[0046] The setting of the bandwidth rate can be realized through forced negotiation. Example 1: Negotiate the data rate of the Ethernet chip at the wired end to a lower rate through forced negotiation, which is lower than the data rate of the wireless path, and send the test traffic from the first test device corresponding to the wireless interface to the packet receiving interface of the router , so that the sending queue (stack) at the wired end and the receiving queue (stack) at the wireless end will be in a full state. Example 2: By forcing the wireless network card with a low data rate to make the data rate of the wireless end of the device under test lower than the data rate of the wired end, the test traffic is sent from the first test device corresponding to the wired interface to the packet receiving interface of the router. The transmit queue (stack) on the wireless side and the receive queue (stack) on the wired side will be full. In this way, the robustness of sen...

Abstract

The invention relates to a method and system for testing the robustness of a data path of a router. The method comprises the steps: configuring a first interface and a second interface of the router, a first configuration testing device connected with the first interface, and a second configuration testing device connected with the second interface; leading the second configuration testing deviceto be visited by the first configuration testing device; setting the first configuration testing device to work at a first bandwidth and the second configuration testing device to work at a second bandwidth, wherein the first bandwidth is far larger than the second bandwidth; using the first configuration testing device to continuously send the test flow with the time length of T to the first interface, and using the second configuration testing device to receive the test flow through the second interface; and detecting whether the working state of the router is normal, and obtaining the detection result. The invention also relates to the system for testing the robustness of the data path of the router. By adopting the scheme, the invention can better test and verify the robustness of sending and receiving queue (stack) software treatment within a shorter time, so that a testing method under the abnormal condition can be provided.

Description

technical field [0001] The invention relates to the field of router testing, more specifically, to a method and system for testing the robustness of router data paths. Background technique [0002] figure 1 Taking the investigation of the robustness of the LAN To WAN data path of the router as an example, a general topology for testing the robustness of the LAN To WAN data path of the router is shown. Because the chip solutions are the same or the capabilities of multiple chip solutions are equivalent, usually the router's LAN (Local Area Network, Local Area Network) interface and WAN ((Wide Area Network, Wide Area Network) interface support the same rate mode, for example, both are Gigabit Ethernet The usual practice is that the LAN interface is connected to the test PC with a Gigabit Ethernet card, and the WAN interface is also connected to the test PC with a Gigabit Ethernet card, and then use the contract sending tool to continuously generate the size from the test PC a...
