Advantages of multi-layer switching technology in network management applications

Multi-layer Switching MLS: Multilayer Switching) provides high-performance Layer-3 Switching for the Catalyst 5000 Series LAN switches. Multi-layer switching uses advanced integrated circuits for specific applications to exchange IP data packets between subnets, the standard routing protocol is used to determine whether a route involves OSPF, OSPF, RIP, and other routing protocols ).

Multi-layer switching hardware-based layer-3 switching technology can free the router from the increased workload of forwarding "Single Point transfer IP" packets in the shared media network technology. Whenever there is a partial or complete switch path between two hosts, data packets are forwarded by the layer-3 switch function. However, data packets that do not have certain or fully switched paths to their destination are still forwarded using vrouters.

In addition, multi-layer switching also provides the data stream statistics function, which is an important part of its switching function. These statistics are used to identify data flow characteristics and can be used for network management, planning, and troubleshooting.

Benefits

Multi-layer switching technology has many distinctive characteristics that distinguish it from other network management technologies. Therefore, it also has its unique advantages when applied to network management.

Transparency: you do not need to modify the endpoint system or rename the subnet. It can work with DHCP, and does not need new routing protocols.

Fast Convergence: With this feature, you can use hardware to assist in failed operations on entries in the information flow to respond to route failures and changes in the routing topology.

Recovery capability: Provides the advantages of HSRP, but does not require additional configuration. With this feature, when the primary router is offline, it can transparently switch the switch to the Hot Standby Router, which eliminates the problem of single point of failure on the network.

Accounting and Data Stream Management: with this function, you can view the exchange of data streams, which helps to troubleshoot, manage data streams, and execute the centralized account function.

Network settings are simpler: This feature allows you to accelerate your network, but retains the existing Subnet Structure. This feature makes it unnecessary to consider the number of layer-3 network segments in the enterprise's network design.

Fast connectivity between Working Groups: High Performance Requirements for connectivity between Working Groups are met through Intranet and multimedia applications. With the multi-layer menu switching technology, users can obtain the benefits of switching and routing on the same platform.

Media speed for accessing the server group: with this function, you can directly connect servers with multiple VLANs without managing them in a centralized manner. By providing security based on information flows one by one, you can control access to servers and filter data streams based on subnet numbers and transport layer application ports, it will not adversely affect the switching performance of the third layer.
