Layer-4 Switching level of the OSI Model Transport classified as grade level, which is responsible for data communication End-to-End, or between the recipient and sender. Coordinate with the communication between the source and destination on the network. A class that uses the TCP and UDP.
Layer 4 Switching will provide tools that can be arranged. Configuration. The network in the form of Application by defining how the Security screen, as well as levels of service (Class of Service) to control the network better.
Layer 4 Switching Hardware still has more acts of Traffic statistics for each Port, which features these Work in the form Application to collect Traffic is made on the basis of information of Layer 4 Application Information (in addition to Layer 3 IP Header) which allows network administrators to control and investigate the network better. For example, 3COM CoreBuilder to support RMON on the operation of each of the Port Switching Hub.
Layer 4 Switching Hub will have a table of data used for the Forward, which is a particularly large store Table it in the core of the Enterprise Hub at Layer 2 and Layer 3 Switch are likely to be the size of the table Forwarding whose size is proportional to the number of devices on the network at Layer 4 Switching must be more than that is. double Because the network is used. Application-level protocol with various Therefore, the size of the Forwarding Table is growing in size rapidly. The number of network devices. Type of Application, including increased as well.
Summary The purpose of the Layer 4 Switching.
* To get better performance. On the basis of the information in Layer-4.
* Provide support. Routing protocols provide. There are also security screening systems and support Multicast (sending information only group).
* There are various Class of Service for Application.
* Routing Table has a large support under Forwarding Traffic on Layer 4 information, as well as improved administrative systems in the network.
