Embodiment Construction

[0030] The working process of the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] As shown in FIG. 1 , the network processor includes a flow analysis module 1 , a flow classification module 2 , a flow distribution module 3 , a flow search module 4 , a flow database 5 , a flow update module 6 , and a flow forwarding module 7 .

[0032] (1) After the network processor receives the message, it first goes to the stream analysis module 1 for processing. The main function of the flow analysis module 1 is to extract the fields set in the message according to the register design and connect them together to form a 128-bit key value, which is provided to the flow classification module for 2 lines of message classification; the hardware flow analysis module 1 can It can extract 6 independent fields from the message header to form the key value. The length of each field does not exceed 16 bytes, and...

Abstract

The utility model discloses a stream-based strategic routing method on a network processor, comprising following procedures: after receiving the message, the processing is carried out by a stream analytic module, and the heading key assignment is extracted and supplied to a stream sorting module to process the key assignment; a stream distribution module decides to send the message to the specific threading of the stream sorting module. The searching and handling are carried out by a stream searching module in the stream database to see whether the same stream mark as that of the message already exists; if the search succeeds, the message is handed to the stream distribution module for disposal; and then the message is transferred to a stream forwarding module for further processing through the stream distribution module. If the search fails, the message is transferred to a renewal module for disposal. The stream renewal module establishes relevant stream list entries and then stores them in the stream database, and then, begins a new search. The utility model can adopt different routing strategy according to various application types, so that the availability of the network is promoted.

Description

technical field [0001] The invention relates to a strategy routing method, in particular to a flow-based strategy routing method implemented on a network processor. Background technique [0002] Traditional routing policies use routing tables derived from routing protocols to forward packets based on destination addresses. Under this mechanism, the router can only provide users with a relatively simple routing method according to the destination address of the message. It is more to solve the problem of network data forwarding, but cannot provide differentiated services. [0003] Policy-based routing provides network managers with stronger control over packet forwarding and storage than traditional routing protocols. Compared with traditional routing, policy-based routing has stronger control capability and more flexible use. It enables network managers to select forwarding paths not only according to destination addresses, but also according to protocol types, packet sizes...
