Ethernet switch development status quo

At present, the development of Ethernet switches is very rapid. Here we analyze the development status of Ethernet switches. MPLS switches follow the trend of combining ATM and IP addresses. Multiprotocol Label Switching (MPLS) is a tag exchange technique between Layer 2 and Layer 3. It is specially designed for IP addresses, the high-speed switching capability of the second layer can be combined with the flexibility of the third layer, so that the IP network has high-speed switching, traffic control, QoS and other performance. Its emergence is accompanied by the development of the network.

As MPLS applications keep increasing, MPLS support is no longer an additional requirement for products or networks, but must be a necessary function. In addition, MPLS from the backbone network to the edge network is also an increasingly obvious trend, this process will give the edge network more bandwidth, higher intelligence and more services. In the access network, using MPLS technology to carry Ethernet switches makes the network more easily upgraded and elastic. A common Ethernet switch can only process 4000 VLANs in each backbone network. MPLS enables each router to support up to 1 million tags. Therefore, there is no doubt that core router manufacturers support MPLS, such as Huawei Quidway NetEngine products. edge router manufacturers are also paying attention to MPLS.

From the perspective of the overall network development direction, in the future core network, all new operators will establish backbone Internet networks in the first place as optical nodes. MPLS is no longer a single existence, and it will complement the underlying optical devices. The previous IP addresses were the first layer, the second layer, and the third layer. Now, using the basis of MPLS, IP addresses are combined with the underlying optical devices to allow optical cables to identify IP routes, that is, IP-based routing is used to drive the network. In the future, the core of the network is wavelength routing, while the outside is a main road routing. This is the necessity of the core of the large network in the future. For carriers, the relationship between today's network and the future network is that all other networks of today's telecom, such as ddnleased line networks and ATM relay networks, it will be the Access Node of the entire large network in the future. This network will not discard all previous technologies and products, but integrate them, but all applications must be implemented in the form of IP addresses, all things end in the Internet and routing class in the form of IP addresses.

Currently, China's backbone network bandwidth usage is less than 10%. Therefore, how to attract more users to use network resources is a concern of operators and service providers. Router manufacturers all see the best use of MPLS is to integrate networks carrying a variety of different types of services into a single network. Most network operators and service providers believe that using MPLS to unify various services is a long-term development direction.

Ethernet Switch

In addition, Ethernet switches are another important role in the switch market. With the development of the information and communication industry and the advancement of information technology in the national economy, the Ethernet switch market has steadily increased. Ethernet features high performance, high flexibility, relatively simple, and easy to implement. Therefore, Ethernet technology has become the most important LAN construction technology today. In the global data network, Ethernet occupies an absolute advantage in quantity. Therefore, it is obvious that the use of Gigabit Ethernet technology can avoid compatibility issues caused by network upgrades, and reduce the high costs that may result from network upgrades.

Therefore, Gigabit/10-Gigabit Ethernet has great advantages in both technology and practical applications. The application scope of Ethernet switches must also become wider and wider. At the same time, due to the popularity of network applications, the rapid growth of users, so with the development of the access network technology, Ethernet access switch has become a market with great development potential, it has become another new growth point in the market.
