2019 Data Internet market will reach nearly $ 5 billion

ACG research firm expects the global optical fiber data center interconnect market will grow from $ 1.1 billion in 2014 to $ 4.7 billion in 2019, a compound annual growth rate of 44.9%.

"The growth is mainly affected by the fiber DCI markets services to data center and cloud migration demand-driven, because service providers need to simplify deployment model and deliver new services and differentiated services", ACG intelligent transport network Practice Leader Tim Doiron said, "The new expansion data center deployments are subject to a variety of service providers including Internet content providers, network service providers and swap providers and promote business. As more and more functions to develop into automation and virtualization, data center interconnect on the capacity, flexibility and versatility of demand will continue to grow, promoting reliable, cost-effective high-speed data center interconnects demand is also a corresponding increase. "

ACG also evaluated the fiber DCI product sales trends, including long distance and metro applications, whether it is large or small multi-slot rack device packaged fiber accessories. ACG platform is expected to Metro DCI (DCI connection support distances up 150km) will continue to dominate long-distance applications. However, metro and long-distance category CAGR will reach 51.5% and 24.6%.

During 2014 to 2019, especially in North America will continue to lead the Americas DCI fiber sales. DCI markets in Europe, Middle East and Africa and the Asia-Pacific region has grown rapidly in the past few years, but still only half the American market.

According to ACG, on the platform types, most optical fiber DCI deployed using a multi-slot chassis products. However, a big wave SFF-like platforms, such as Infinera's Cloud Xpress, Ciena's Waveserver, ADVA Optical Networking's FSP3000 Cloudconnect and 1FINITY T100 have been or are being paved the way to market Fujitsu.

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.

Lightcounting cut annual optical module market growth

Market research firm Lightcounting latest quarterly report in September this year a combination of the first half of global operators, Internet companies and communications equipment, devices and corporate earnings since the third quarter shipments data and dynamic communications companies. Their analysis shows some interesting results.

LC pointed out that the second quarter of this year compared to the year before, the investment in Internet companies in the field of large data centers increased by 7%, while telecom operators to invest in the telecommunications sector decreased by 12%. Reduce telecom operators to invest mainly receive complete the world's major telecom operators some major investment projects, such as China Mobile LTE deployment, while the growth rate of the Internet companies to invest in the situation significantly better than in previous years.

Year comparison, sales of data communications equipment manufacturers in the field of growth of 2%, telecommunications equipment grew by 4%. White box manufacturers continue to win market in the area of ​​data center equipment. In the field of telecommunications equipment, Huawei and ZTE continue to gain market share. Pressure on prices may be a factor, but operators have become cautious in the evolution of SDN / NFV may also be the cause.

Device manufacturers in the data communications segment grew 10%, an increase of 7% in the field of telecommunications. Increased deployment of 100Gbps device should be the reason behind this beautiful figure, the price is usually higher 100Gbps devices. Divided by product type, the following figure shows the different types of optical components market performance in the second quarter. Optical connector market growth, although high, but due to low prices, overall sales remain low, slightly higher than $ 50 million. Broadband construction to benefit from China's, FTTx market continued to maintain a rapid growth. China's future investment in LTE-building wireless networks will also stimulate the growth of optical device market. Overall, Ethernet and WDM optical devices is still the bulk of optical components market.

In the August report, Lightcounting had predicted annual optical module market growth of more than 25%. But then some of the light module manufacturers lower growth, the Chinese market situation may change, Lightcounting decided to optical module market growth from 25% down to 15%. Even so, the annual light module market will reach $ 4 billion. The rapid development of emerging companies may supplement the decline of traditional manufacturers performance.

ROADM market entered a rapid growth period

According to well-known market research firm IHS Infonetics latest report shows that in the optical transmission market, in addition to still maintain a rapid growth outside 100G, ROADM market has become another one star. 2015 second quarter, ROADM market income ratio in the entire WDM market revenue up 45%. The report predicts that, ROADM market in 2015 revenue will grow 12% in 2104, and 2019, the market's compound annual growth rate as high as 12%, which greatly exceeds the entire WDM market compound annual growth rate of 9%, to become the next four years, WDM segment of the market the fastest growing segment.

Figure: Infonetics report ROADM market entered a rapid growth period

As can be seen from the chart IHS Infonetics report, in fact, starting in 2011, ROADM market performance had already started to speed, there's little need to explain that, 100G technology is also starting in 2011 at a global scale commercial. It is a coincidence?

Let's take a look at the status quo of large cities in China, the road to development, and perhaps give us some enlightenment. In recent years, some large cities continue to build and expand roads, often encounter the problem of the transformation of urban interchange. Some design and construction of transportation hub earlier, in the rapid development of today's urban road traffic has become the bottleneck. Similarly, the development of optical networks is also facing a similar situation. With 2011 global begin large-scale commercial 100G coherent optical transmission technology, many operators have seen the super-high-speed optical transmission technology challenge existing optical network architecture, and embarked on a strategy to reshape the optical network architecture project. Therefore, it is not a coincidence, but the optical network development inevitable trend.

Technology and market jointly call new networking technology of optical network

With the rise of Internet penetration to various industries in various fields, as well as cloud computing, big data, networking and other technology applications, data traffic is continuing to grow rapidly. According to IHS Infonetics analytical report 100G module shipments increased from 2011 in 2000 to 2014 or so quickly over 120,000. 100G optical transmission system on a global scale is rapidly expanding. In recent years, the industry has set his sights on Super 100G technology. Alcatel-Lucent deployed the world's first commercial 400G optical transport network in 2013, its 200G wavelength-division-board programmable achieve volume shipments in 2014. According to market analysts predict that by around 2017, 400G will gradually begin large-scale commercial.

You can see from the above data, ultra-high-speed optical transmission technology is rapidly improving the transmission capacity of the fiber, which makes electrical cross-way network to OTN optical network node is facing great challenges. According to the development trend of optical networks, long-distance backbone and metro core network topology often will tend to grid, the dimensions of each node may reach 8-dimensional, or even more. In this case, if pure electric cross 100G OTN networking mode, which means that the capacity of each node will reach 8x8T = 64T. If you consider the way for future 400G OTN network, then the capacity will be close to 200T, which is currently on the market, the largest capacity OTN electrical cross-connect equipment is far unable to meet. Meanwhile, large-scale OTN electrical cross matrix bound to bring higher power requirements and cooling requirements, as well as the difficulty of network evolution challenges operators have realized in the actual deployment of the deployment faced.

Future-oriented development, technology and markets are calling the new Optical Networking technology.

SDN development of optical networks exist different technical route

Comparative data networks SDN different optical network SDN has its own unique characteristics. First, due to the characteristics of the physical layer, the optical network control architecture itself has control forwarding separation. Secondly, centralized control, optical network has a mature network management, the path calculation unit (PCE) and other centralized management and control systems. Third, the light has the characteristics of a connection-oriented network, all traffic using pre-configured, without the controller forward packets according to the following service packets instant hair flow, reducing the controller performance requirements, with better network scalability . We can say that the optical network already has some characteristics of SDN for evolution to SDN has laid a good foundation. But on the other hand, optical network physical layer device programmability weak, resource virtualization and sliced ​​more difficult to achieve, so that the light is introduced SDN network technology there are some difficulties.

SDN optical network based on the characteristics of the development of optical network SDN take the evolution of ideas and data networks SDN differ. Meanwhile, the optical network backbone, metro and access layer development needs and the technology used different, SDN also introduced different technical route.

(1) Route One: enhancement based on optical network control plane, stressed north to open interfaces.

Backbone OTN, DWDM optical network equipment and other support capabilities better control plane, based on the existing ASON / GMPLS control plane and centralized path computation unit PCE technology, to interface to achieve SDN centralized control by extending and enhancing management and control capabilities and open PCE North devices, applications and services and provide open programmable upper network and applications. This route can better protect existing technology investment, and facilitate smooth network evolution. Since the optical network physical layer private information more difficult to south standardized interface protocol is relatively large, south to the interface may allow multiple interface technologies.

(2) Route II: Introducing openflow agreement, stressing the south to open interfaces.

For packet transmission PTN and PON access network equipment, it does not have the intelligent control plane, can be introduced directly on the device openflow agreement to achieve south to an open and standardized interfaces. This route due to the realization of the South to interface standardization, equipment and services in favor of decoupling, simplify network node function, reduce equipment costs, ease of operators for metro and access massive multi-vendor sites centralized management control. For existing network equipment has been deployed, will consider implementing a centralized controller capacities through network upgrade approach.

WDM and SDH difference?

SDH, called "digital synchronization sequence", mainly used for drop multiplexing E1 (2M), E3, T3, STM-1 ~ STM-64 and other ranking data transmitted. And it can be various types of data such as: ATM, E1, FE, GE and other types of data transmission unified package, compatibility strong;WDM, called wavelength division multiplexing system with DWDM and CWDM points, primarily distinguished by the frequency of the light wave signals of different channels used to transmit signals, which can carry include transmission SDH, FCOM, GE and other large particles of business, Mainly used for inter-provincial and provincial transport network.
