Problems solved by technology

The price of network test equipment is very expensive. In order to save costs, equipment developers often only purchase fewer test ports
Nowadays, the number of ports of large-scale carrier-grade switches can often reach hundreds of ports, and the bandwidth of the backplane can reach hundreds of G. It is difficult for existing test equipment to achieve a considerable number of ports.

Embodiment Construction

[0032] The technical solution of the present invention is further described below.

[0033] First, define the terms that will be used below:

[0034] 1) Ethernet switch: It is a network device based on MAC (hardware address of network card) identification, which can complete the function of encapsulating and forwarding data packets. The switch can "learn" the MAC address and store it in the internal address table. By establishing a temporary switching path between the originator and the target receiver of the data frame, the data frame can directly reach the destination address from the source address.

[0035] 2) Wire speed: The theoretical maximum value of data forwarded by the switch.

[0036] 3) Backplane bandwidth: The backplane bandwidth of the switch is the maximum amount of data that can be handled between the switch interface processor or interface card and the data bus. The backplane bandwidth marks the total data exchange capability of the switch. The unit is Gbps...

Abstract

The invention comprises the following steps: the port of network test device is connected to the network port of exchange; using network port simulated by the network test device to simulate the user in network, and meanwhile sending and receiving the test data message; examining the data receiving state to determine the forwarding performance of the exchange; the port of tested Ethernet exchange is connected to the port of network tester; wherein two testing ports are used to test several ports of the exchange.

Description

technical field [0001] The invention relates to the test technology of the Ethernet switch, more specifically, to a method for testing the forwarding performance of the Ethernet switch and a network configuration method thereof. Background technique [0002] With the development of data communication technology, the performance of Ethernet switches has been greatly improved, and the port rate has gradually developed from 10M bps and 100M bps in the 1990s to today's 1000M bps and 10000M bps. In order to realize wire-speed forwarding between ports of the switch (that is, forwarding according to the maximum rate of the ports), the switch needs to have a larger backplane bandwidth. Generally speaking, the backplane bandwidth of the switch needs to be equal to or greater than the sum of the highest port rates of all ports of the switch, so as to ensure that the switch forwards data at the wire speed. [0003] In the past, when comparing switch backplane bandwidth and forwarding ...
