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.
