Development Status SDN technology
SDN technology I believe we are no stranger to many people even have ears hear the calluses. After a period of controversy, SDN has finally been recognized by some of the data center market, began expanding the size of the relevant market, the market size in 2015 is expected to SDN switches and controllers will be more than 1.4 billion US dollars, and by 2019, this figure will reach $ 12 billion. SDN technology data center has been gradually recognized by the market for the development of the data center has brought vitality, which just a few years ago raised when SDN technology is very different, a lot of technical conservatives no longer ignore the existence of SDN technology, began to accept even like SDN technology, so the market opportunity came out. Compared to a few years ago talk SDN technology, now we have begun to emerge scale commercial trial, but to the number of data centers are being tested SDN technology program, a thriving affect SDN technologies emerge.
SDN is a change in the traditional network technology, breaking the technical barriers to the traditional network, allowing network technology to open. In the data center, the only network technology is the most closed technique, each network technology manufacturers all play each, have a lot of proprietary technology, which makes a lot of network equipment interoperability difficult, to the development of network technology, data center development have brought resistance . The network has become a stumbling block to the rapid development of the data center, it must make changes to the network. It is in this context, SDN onto the stage was. Although SDN wonderful dance, can not understand the appreciation of the audience are seated audience, or even think of SDN danced well ugly, so the emergence of SDN be more challenged, the development of resistance is not small, but not the network Support giant companies, almost unable to move. Not long, cloud computing, big data, virtualization technologies are fire, these new technologies detonated a data center, however, these techniques rely on a network are SDN, which highlights the importance of the SDN, only have the ability to network SDN to cloud computing, big data, virtualization techniques communion. At this Internet giant manufacturers have to accept SDN, joint networking vendors strive together for the network open. This time, SDN really angry, especially since 2015, with SDN network technology based data centers around the world, the country is also true. Three operators SDN and network manufacturers to do the test in the actual deployment of network applications, three Internet giants have been deployed in the data center SDN technology, these SDN deployment has played a good role model, peace, human security, government, banks, etc. hundred hundred lines industry giants are beginning to test and deployment of SDN, SDN technology has been widely promoted.
SDN hot market is one thing. In fact, from a technical point of view, is not currently commercially available SDN SDN original definition, in accordance with the definition of SDN by the controller to automatically manage the entire network, issued a stream table, traffic forwarding through the flow meter. This design for completely new data center, can be adapted, but the face of massive existing data center, are facing can not be practical situation. Massive data center contains a variety of network equipment, different manufacturers, different protocols and different specifications, which SDN controller is also compatible with these devices can not be, and traditional network devices do not support flow table, so that the data center is not possible to deploy SDN, which will replace all of these devices, these devices for the data center is the most precious asset, needs to be replaced gradually, upgrading it to deploy SDN brought great difficulty. Even for the new data center, we need the support of all network devices send flow table, and now all network controller manufacturers can not compatible with each other, so that the construction of such a SDN network, you can only choose an online vendor of all devices and controllers , which for a data center is very negative, which will purchase network equipment and a lack of future devices on the network operation and maintenance bargaining power, so in general the data center will purchase two to three network equipment manufacturers of equipment, compared with each other, merit-based selection, Thus there is a number in the network of network equipment, SDN nature can not be deployed, SDN technology to unify the online world is still a long way to go.
The current status of data centers SDN technology applications actually uses two deployment options, one is no controller scheme, which is clearly still a need for manual configuration of network equipment, changes in servers, network devices need to manually do some networking configuration change, but also the deployment of such networks VXLAN, NFV, TRILL and other SDN with technology, these techniques can be realized through a virtual machine across a data center server stateless migration, which no controller program but also to allow data center in the future Prepare to have the controller direction; the other is to have controller solutions, network equipment in the fiber optic interconnect good, good basic configuration interconnect port after delivering network configuration by the controller, when issued not flow table configuration, but the actual network configuration, such as ARP, MAC, routing these network elements to achieve up among all the devices within the network. When such change or increase during network equipment NE, own calculation by the controller to automatically deliver the configuration, which will greatly reduce the workload of operation and maintenance, the benefits it brings to the data center is obvious. This program, although not with a controller flow table under real hair, but already has a network of automated management software capabilities, the most important is that such programs can be compatible with existing data center network, is currently the most popular SDN program, which Species SDN program is not lofty, very down to earth, it was widely recognized. The last is a natural flow table SDN standard definition programs, this ideal SDN program, in fact, there is little use, but in some technical strength of strong research data center testing is still relatively far away from the actual commercial.
Although SDN applications and SDN standards vary, but gained more recognition in the data center began large-scale deployments. This SDN program is still not break the barriers between network technology, manufacturers of controllers on different networks have different, because there is no flow table, naturally they do not comply with OpenFlow protocol, so the current controller for manufacturers but also between the various networks closed, not for outsiders. This SDN solutions for data center operation and maintenance convenience brought on, but still not breaking the blockade network between manufacturers, have to say is a pity. However, SDN development just on the right track. I believe that with the white box switch mature, chip manufacturers on OpenFlow support is getting better, the real SDN technology will obtain greater future development, data center network inevitably more open.

H3C Connect+: let the data center, "Moving"
In the wave of the Internet+ boom, driven by the gradual expansion of construction scale data centers, data center hosting services network is facing pressure surge, operation and maintenance more difficult, how to solve this problem has become the industry focus. Recently, large interconnected Hangzhou H3C Technologies Co., Ltd. (referred to as "H3C") at the Connect+ strategic conference to launch the application-driven data center solutions, to provide users with better data center business resilience deployment, unified management It provides the most practical solution.
Traditional data center construction as a project, each application needs to set by the network, compute, storage, consisting of the underlying architecture, traditional data center is "solid", lack of flexibility and scalability. With the development of business, increase application and data center management software carries more, increasingly redundant system, if the business needs to be adjusted, it is necessary to change the data center architecture, and traditional manual modification high error rate, as well as the deployment of business out slow. In addition, once the network equipment problems, it will affect the business operation of the entire data center to the enterprise serious economic losses.
New IT technology-driven data center transformation, has been one of the key H3C concern. Faced with the user's data center build for the future development, Connect+ H3C's has a very clear point, that is, on the basis of the new release of application-driven network architecture, based on scenarios for data center applications, the development of application-driven data center solutions to achieve business elastically stretchable, minimalist operation and maintenance, to build end service chain, to better integrate the large Internet Connect+ strategic landing.
From the characteristics of view, H3C application-driven data center solutions through hardware resources, NFV pool technology, as well as a cluster controller upward VCFC build resilient network, flexible scheduling resources to service deployment easier; at the same time With the overall platform, form the entire network hierarchy management, resource automatically migrate, there is a problem in the system or re-deployment process, the formation of the business system does not perceive the state, complete and correct operation.
For users, H3C application-driven data center solutions bring value that allows the user via a standard infrastructure, software-defined data center gives the ability to implement the entire network service elastically scalable, automated intelligence and secure. Data Center Planning for confusion often encountered during operation and maintenance, the user can make use of H3C solutions, business address and Internet address are independent, simplifying planning and realization of a one-time physical network configuration, make operation and maintenance easier management more efficient.
In practice, these values have also been tested, such as Tencent data center by deploying H3C application-driven data center solutions, successfully used to take 3-5 days to multiple data center services on-line, the deployment is completed within 1 day , efficiency is improved by 70%. In addition, Tencent also through network virtualization to achieve IT rational allocation of resources, making the effective and rational use of resources, greatly reducing the cost of investment.
Currently, software drivers, application of the concept of the first, has become the industry generally accepted direction. For data center construction, the floor of the road to achieve these concepts is still very long. To be sure, flexible, dynamic data center is the future trend, I believe that with the help of three communications in China, there will be more users join the network change to application-driven parade, with new IT technology to meet the challenges of large Internet era.

Five network challenges of the future trend of development of enterprises
With the emergence of cloud computing and accelerate the deployment of large and ultra-large-scale data, data centers, network managers must constantly readjust and further development of the network. Under the impetus of this challenge, a variety of new technologies and new standards have emerged, not only can be used to improve and optimize the network capacity, security and flexibility, while controlling costs. Let us look at the top five trends in 2015 and the network to the user's meaning.
Trend 1: 802.11ac rapid spread
Enterprise networks are at the peak of a new era of mobile computing, tablet PCs and smart phones can be seen everywhere in the workplace. As the number and deployment of enterprise cloud services, mobile devices continues at an alarming rate of sustained development, network managers must rethink how they will provide the protection and control of enterprise computing resources and information access.
According to IEEE 802.11ac standard, 5G 802.11n wireless technology when compared to its predecessor, not only three times faster, the power efficiency is improved by six times, while maintaining the 802.11n and legacy 802.11b/g/a wireless interface interaction operability. Infonetics recent data show that sales of 802.11ac access points increased by nearly 10-fold in the past year. This gives enterprise technology managers to better manage and protect their network connection point tremendous pressure.
Figure 1: Wi-Fi technology evolution shows that the development process as well as the rapidly growing exponentially handling capacity over the past 15 years, currently 802.11ac (5G) has reached 3.6Gbps. 802.11ac access points 10-fold increase in sales to the enterprise has brought enormous pressure.
Trend 2: wiring closets 2.5G and 5G coexist
With 802.11ac Wi-Fi Wave Release 2 flow rate through the access point will be more than thousands of megabits per second, we need an access point and Ethernet switch port expansion to 1000 Base-T (1G) above. However, due to the length it has been put into use over five and six cable of millions of feet of business operations are seeking through this existing single pair unshielded twisted-pair copper to fill vacancies between 1G and 10G.
802.11ac Wave 2 standard will usher in a progressive multi-user MIMO antenna technology and other technologies to help the theoretical maximum wireless speed up to 6.93Gbps. With respect to the typical 10 times the speed of the Ethernet trail, this creates opportunities for faster Ethernet speeds and quickly upgrade to a rate of 2.5G and 5G. Although the newly installed equipment will be used wisely to support 10G super six cable, but most of the existing installed base will stay in 1Gbps, or when you need more than 1Gbps uplink rate using 2.5 / 5Gbps rate.
Existing programs in a variety of industries through existing five / six cable support 2.5G / 5Gbps same time, the industry needs a unified standard to avoid confusion between the various solutions and non-interoperability. This might give this potential emerging market adversely affected. The good news is, IEEE 802.3 standards bodies are working on the multi-rate Gigabit Ethernet BASE-T program by 2.5G and 5G used in enterprise access point.
The focus of this work is the need to achieve the goal in the near future and is currently installed through UTP (100 meters 2.5G) and six (100 meters 5G) cable. Because of limited bandwidth, convenient way to achieve this is to use a higher modulation scheme.
Join in the wiring closet Ethernet link protocol 2.5G and 5G rate, not only will achieve enterprise access point network bandwidth low-cost expansion, but will also provide more data rate options for IT professionals.
Trend 3: Data center 25G, 50G and 100G
Enterprise and cloud environments network operators must comply with technical roadmap carefully planned build its own network in order to expand based on changing needs. Typically, these carriers must maintain the lowest possible capital and operating expenditures (CAPEX / OPEX) while the balance of performance optimization. One way to achieve these often conflicting objectives is to upgrade to higher-speed Ethernet technology.
Experts predict that the biggest cloud service providers to upgrade to 100G Ethernet architecture, and low cost 25G and 50G will continue to be the majority of the other well-known companies in the data center of the main force. 25G / 50G Ethernet Alliance is a relatively new organization, it has its 25G and 50G Ethernet specification is open to all suppliers of data center ecosystem (royalty-free) to create and deploy interoperable Compliance product implementation. The standard can accelerate 25G and 50G Ethernet ports widely deployed, it also happens to be synchronized with the cloud architecture suitable for the introduction of 100G Ethernet.
25G / 50G standards may appear to be some kind of backwards, because 40G and 100G Ethernet already exists, but it is mainly used to meet the needs of lower-cost rate, especially low-cost speed demand cloud data center servers. For example, 25G and 10G wiring have substantially the same cost structure, but the performance is 2.5 times the 10G. Similarly, 50G cost is half of 40G, but the performance increased by 25%.
Trend 4: Cloud-level network
How can companies reduce mobile network costs while improving efficiency and flexibility of their IT infrastructure? Virtual networking, storage and servers are reshaping the way businesses use IT. Cloud computing plays a crucial role in this process, you can provide network access to computing resources and a huge amount of complex applications.
Cloud technology to provide more capacity to fully meet the third-party business or small business increasing demand, which can provide enterprises with a need to invest in new IT infrastructure will be able to increase the capacity of the route. Will host processing and data to the cloud, it frees capacity of network managers, they can create the capacity re-allocated to the data location and control device generates the data. Ethernet networks can be designed to achieve low latency and high bandwidth, can fully meet the needs of all the efficiencies of cloud computing to achieve its value.
Figure 2: Cloud-level network has three elements, namely, the physical network layer, network services and SDN and NFV platform support. The physical network layer elements can provide a blueprint for efficient network design. Low-cost network services can be expanded to achieve high performance for all workloads, while SDN and NFV can achieve dynamic service configuration and faster innovation and deployment.
Trend 5: Open Source Network
Cloud-level network without software is useless, and each part of the switch also requires the operating system. The software must provide a hardware-independent network operating system, an abstraction layer on a commercial switch chip, like Linux and Windows provide the same abstraction layer on the server side.
Eliminate patent barriers and allows developers to collaboration, debate, integration and motivation to each other, is an important advantage of open source network. Gartner predicts 2015 open source technology will be included in 85% of commercial software packages, 95% of major IT companies will use some elements of open source software.
For decades, customers have been buying servers, patent portfolio data storage, networking and software. Now, these customers require the system to use a different approach with, so open source software can be combined with existing hardware and its internal legacy systems. This method is expected to bring advantages to mix and match the speed, cost and innovation.
Traditional "one factory dominant" proprietary solutions are into "flourishing" multi-vendor mode. This can be a significant cost savings for customers in any market area and bring noteworthy performance optimization for them. And now the challenge has been transformed into how successfully integrated these systems suppliers. Fortunately, the server and PC market to provide a template, which can be through a new open-source hardware, open source software and open standards will combine all of this complete integration.

Hong Kong FTTH penetration has reached 82%
On 8 September 2015, held the world's ultra-wideband Forum, Peter Lam PCCW-HKT, general manager of engineering department director level to share broadband development in Hong Kong.
Peter Lam expressed, PCCW has 100% of pay-TV, Huawei also our partners in the mobile space, and last year our entire network can achieve 300M bandwidth, and now we can achieve 3 carriers mobile network bandwidth. For residential customers in Hong Kong, he introduced a lot of high-rise buildings has become a landmark in Hong Kong, Hong Kong, more than 80 percent of the buildings are high-level, in this real estate layout, PCCW already has 82% of FTTH penetration, we can realization within four days of the fiber to the home, while FTTB penetration reached 77%.
PCCW past many networks are copper network, starting in 2010, PCCW begin large-scale FTTH deployment, Peter Lam further stated, HKT is Hong Kong's largest ISP, we are very proud that we are the first optical fiber instead of copper network in Hong Kong operators, is also the largest IPTV provider, which gives us a double benefit, fiber to the home for future consumption of high-bandwidth pave the way, to promote the development of mobile services, LTE network, 100% fiber ensures the 100M back pass rate. Other operators are required to rent mobile backhaul networks.
PCCW customers currently installed basically 500M to 1G networks while PCCW has begun deploying 10G networks to the home, which for PCCW to enter the field of intellectual life has brought convenience.

SPTN technical architecture
SPTN system architecture consists of the forwarding plane, the control plane, management plane and application plane composition, shown in Figure 1.
When the number of network elements of a network control capability is greater than the controller needs to perform NE-level multiple controllers to control. In order to meet the networking needs of large carrier-class network control plane using hierarchical control architecture into the domain controller (D-Controller) and Inter-Domain Controller (S-Controller), in which the D-Controller is responsible for control within the business, and forwarded to the interface control surface equipment through the South. S-Controller is responsible for inter-domain control of the business by calling the North D-Controller provided to interface to complete the resource coordination and operational scheduling of the entire network, cross-domain cooperative control of network resources.
In SPTN system architecture, management plane still persist, management will continue to be responsible for forwarding plane resources and version management, alarm and performance monitoring surface and controllers to meet the needs of network operation and maintenance.
