Method and system for limiting speed of token bucket based on priority

ActiveCN101997766AHigh probability of discardingAvoid the problem of random dropData switching networksDistributed computingSpeed limit
The invention discloses a method and a system for limiting speed of a token bucket based on priority. The method comprises the following steps of: configuring speed limiting parameters of a message according to the attribute of the message, wherein the speed limiting parameters comprise a speed limiting value and gradually decreased depths of token buckets at different stages, and ensuring that the token number in the token bucket at the highest stage is greater than or equal to sum of the token numbers in the token buckets at the rest stages of the token buckets; calculating the token number to be added after receiving the message; limiting the speed of the current message by using the token bucket at the highest stage when determining that priority speed limiting is not needed; limiting the speed of the current message by using the token bucket corresponding to the number of stages of the current message for the messages with the same priority number of the message as the speed limiting stage number when determining that priority speed limiting is needed; and limiting the speed of the current message for the messages with different priority stage of the message from the speed limiting stage number by using the token bucket at the highest stage. Through the method and the system, different messages have different discard probabilities under the condition of the same speed limiting condition, and the service quality of a network is improved.

Method and apparatus for performing packet classification for policy-based packet routing

A method and apparatus for performing packet classification in a digital signal processor for policy-based packet routing. For one embodiment, the digital signal processor includes a policy statement table for storing policy statements. Each policy statement has associated with it a priority number that indicates the priority of the policy statement relative to other policy statements. The priority numbers are separately stored in a priority index table. The priority index table includes priority logic that determines the most significant priority number from among the policy statements that match an incoming packet during a classification of filter operation. The priority logic also identifies the location in the priority index table of the most significant priority number. The identified location in the priority index table can be used to access associated route information or other information stored in a route memory array. New policy statements can be added at any location in the policy statement table, and the associated priority numbers loaded into corresponding locations in the priority index table. Priority numbers of previously stored priority policy statements may be updated such that the new policy statement does not have the same priority number as the previously stored policy statements.
