Problems solved by technology

The current fast-forwarding HASH algorithm is fixed. In order to take into account the comprehensive change effect of the quintuple information, when selecting the HASH algorithm, the changes of all members are often taken into consideration. From this point of view, the current HASH algorithm is not The best algorithm for a specific application scenario, then the forwarding performance of the router cannot be better optimized

Embodiment Construction

[0068] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0069] figure 1 The flow chart of the fast forwarding method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the specific steps are as follows:

[0070] Step 101: For each router, pre-configure multiple fast forwarding HASH algorithms on the router; set one of them as the default fast forwarding HASH algorithm, and pre-configure HASH algorithm switching conditions on the router.

[0071] Here, the fast forwarding HASH algorithm configured on the router is a better HASH algorithm under various traffic types obtained from past experience. In order to facilitate the selection operation of the subsequent step 110, the HASH algorithms can be classified according to the following rules:

[0072] Classify the HASH algorithms with the same arrangement order of the weights of the quintuple components into one c...

Abstract

The invention discloses a method and a device for quickly forwarding a data report. The method comprises the following steps that: a default quick forwarding HASH algorithm and a HASH algorithm switching condition are set on routing equipment; the routing equipment is started and takes the default quick forwarding HASH algorithm as the current quick forwarding HASH algorithm; the routing equipment receives the data report and performs forwarding processing on the report by adopting the current quick forwarding HASH algorithm; when finding that the current quick forwarding HASH algorithm accords with the HASH algorithm switching condition, the routing equipment starts to count variables of flow characteristic components in the received report; and when counting is finished, the routing equipment switches the current quick forwarding HASH algorithm according to the obtained variables of the flow characteristic components. By the method and the device, a HASH conflict is reduced during quick forwarding, and the forwarding performance is improved.

Description

technical field [0001] The invention relates to the technical field of routing equipment forwarding, in particular to a method and device for fast forwarding of data messages. Background technique [0002] Router forwarding performance is a key indicator to measure the cost performance of routers. According to the conventional forwarding process, after a router receives a message, it will search for a matching route in the routing table according to the destination address of the message, determine an optimal path, and then forward the message. Because each message needs to check the routing table, this process is time-consuming and seriously affects the forwarding performance of the router. In fact, most of the data on the Internet is based on data flow. If the characteristics of a certain data flow can be recorded , the subsequent forwarding can be greatly improved by looking up this feature instead of checking the routing table. [0003] In recent years, the concept of ...
