Factors necessary to promote the development of Ethernet Switches

Ethernet switches are still commonly used, so I have studied the necessary factors to Promote the Development of Ethernet switches. I would like to share with you here, hoping to help you. With the free E-mail and WWW services, the Internet is growing rapidly, promoting the rapid development of Ethernet. Nowadays, more and more manufacturers are entering the Ethernet market. New Brands and new products are emerging, and there seems to be a trend of Homogeneous Competition.

However, as Ethernet switches expand in the market, their product quality requirements are constantly improved. At present, the development of Ethernet switches is following three major development directions: speed, intelligent application, and constant expansion. Whether it is for high-end module chassis switches or for low-end fixed port switches, all comply with this development trend.

Speed: main indicator of network performance

Network speed from Mbit/s to Mbit/s is an important milestone in the development of Ethernet over the past 30 years. The arrival of the 10G network age will bring people a completely new and unimaginable experience. At present, people's requirements for bandwidth are rapidly increasing, such as the rapidly developing storage network massive data transmission channels, a large number of hundred megabytes of bandwidth convergence of metro networks, large financial institutions data concentration, enterprise core business, ERP, CRM, and other complex application extensions. Today, the gigabit network is the backbone and the 10-Gigabit network is the mainstream access architecture. It will gradually transition to the 10-Gigabit network and 1-gigabit network access architecture. Like Cisco's next-generation switch products, ipvst6500 and 3750 are typical of the next-generation 10-Gigabit/Gigabit Switch, the emergence of these products in the market provides excellent product support for 10-Gigabit core and 1-gigabit desktop services and the possibility of further network upgrading in the future.

Intelligence: simplifying the network

Networks are changing our ways of learning, living, and working. Today's networks require more intelligent application development to support a variety of people's needs. From Initial email sending and receiving, to multimedia transmission of data, voice, and video, network technicians have achieved stable and fast operation of multiple complex applications with the help of QoS implementation, we are continuously developing vswitches to support innovative smart services. With the implementation of QoS and secure switching, vswitch application technology has become another development direction for voice support. The Intelligent Voice Service of an Ethernet switch can integrate data with voice transmission. The customer only needs to maintain a unified network system, which greatly reduces network management costs. The voice service over Ethernet not only guarantees excellent call quality, but also supports rich value-added application development. For example, you do not need to repeat IP phone numbers, powerful IP phone conferences, and easy-to-use wireless IP phone numbers and IP soft phone numbers. The Application of IP Voice Over Ethernet will bring people from the traditional communication mode to the IP communication era. To support IP communication, in addition to implementing various security exchange technologies that ensure network security and maximize the QoS of effective network bandwidth applications, Ethernet switches are particularly important for online power supply. In addition, as some switches are directly connected to the WAN, more and more switches have some routing functions. Considering the large-scale application of the next-generation Internet Protocol IPv6 in the future, cisco's next-generation switch provides hardware support for IPv6.

Expansion: The network is everywhere

Ethernet is constantly expanding its coverage and is evolving towards wireless and long distance. Wireless Ethernet can meet the needs of people to access the Internet anytime, anywhere, and the world is setting off a climax of Wireless LAN construction. Wireless Ethernet technology has greatly expanded its coverage and is currently a hot technology. The background network technology and the support of the complete infrastructure are the basis for the development of wireless applications. The complete Ethernet architecture ensures the expansion of wireless network space and the perfect use of a variety of smart applications on wireless networks. Some technical companies, such as Cisco, provide users with comprehensive Wireless Network Solutions, positioning wireless networks in the application of group users to facilitate the work and use of customers, A wireless network is built on the basis of the wired network system, so that the wired and wireless networks complement each other and form a good fusion and unity between the two. In addition, Cisco's long-distance Ethernet solution also expands Ethernet over distance. This technology is the Ethernet over the telephone line. VDSL signals are transmitted at the physical layer and Ethernet signals are transmitted at the second layer. It can extend the transmission distance from the original 100 meters to up to 5 kilometers, which is especially suitable for the city range and the speed remains unchanged. Any cable can be supported, greatly facilitating the application.

Modular and fixed port exchange

From the perspective of system architecture, Ethernet switches can be divided into fixed port switches and rack-type switches. Among them, the switch ports of the fixed port switch are basically fixed with the switch; while each switch port of the fixed port switch of the host machine box switch is plug-in and modular, and can be increased or decreased as needed. Generally, the former is mainly used for low-end and Middle-end network applications, and the latter is mainly used for medium-and high-end applications. The products of these two systems will all develop in three ways: speed, intelligent application, and coverage.

A fixed port switch can expand its capacity by means of stacking to increase the overall speed of the network. However, such stacking should not be physically connected together. The traditional stacking method is similar to hub stacking, that is, using a bus to connect vswitches on the backplane. In fact, vswitches are still operated on a single machine and separated from each other, it is impossible to implement a unified traffic policy, which not only wastes bandwidth, but also cannot support the integration of multiple applications. To address these problems, Cisco's next-generation stackable switch ipvst3750 introduces an innovative technology-intelligent stack StackWise. It provides an innovative stack architecture that provides a 32 Gbps stack interconnection, up to 9 switches can be stacked and managed and planned from physical stack to logical data flow. This integrated and optimized device allows customers to deploy voice, video, and data applications with greater confidence. This innovative technology can bring many unexpected advantages to customers of stack switches, such as stack redundancy, distributed forwarding, and QoS based on advanced failover functions based on hardware and software) provides unified services, simplifies management through automatic configuration, meets the requirements of Gigabit Ethernet connections, and supports the Next Generation Internet Protocol IPv6.

The most important trend in the development of multi-Chassis modular switches for the core network is 10 Gigabit. The key of this product is that the component performance in the chassis is getting stronger and stronger. Because of the adoption of a more flexible modular structure, it provides a variety of functional modules beyond the basic connection. For example, Cisco's next-generation ipvst6500 switch is most introduced to ensure its 10g switching performance. It is equipped with a powerful switching engine and a built-in switching matrix, it also uses hardware acceleration to implement high-performance embedded network management, MPLS, IPv6, and other smart service hardware support, and uses distributed forwarding technology to achieve up to mpps of performance. Cisco has also developed many new functional modules based on the original ipvst6500. These modules are compatible with all existing ipvst6500 interfaces and service modules, it provides a cost-effective way for users to port to 10-Gigabit Ethernet. The wheel of technological progress is still rolling forward. Breakthroughs in speed, intelligence, and expansion will bring the development of Ethernet switches to a new level.
