Technology of Ethernet Switch Telecom/Datacom Systems


In the process of data transmission, multimedia data and ordinary data are transmitted in different ways. Multimedia data has higher requirements on network performance during transmission. If you want to improve the performance of multimedia data transmission, you can use information flow priority technology to achieve transmission. There are two commonly used methods for assigning priority to information flow, which are: the first method is to use the switch to complete the confirmation of the input information flow, and then classify the information flow and assign the corresponding priority. The general three-layer Ethernet Switch Telecom/Datacom Systems can be done this way. Another way is to use the terminal to assign priority to the data frame, and place the data frame in the corresponding priority queue, and implement forwarding according to the priority.

The second method allows all Ethernet Switch Telecom/Datacom Systems on the path between the source end and the destination end to recognize the priority mark. There are two organizations dedicated to specifying information flow priority standards, namely IEEE802.IP and IPV4TOS domains. The former is more suitable for switching Ethernet environments, and the IPV4 service type domain priority standards are mainly used in wide area networks.
