Embodiment Construction

[0054] The specific implementation of the present invention will be further described below with reference to the drawings and embodiments. It should be noted that the implementation of the associated technology of the unidirectional flow URI under asymmetric routing according to the present invention is merely an example, but the present invention is not limited to this specific implementation.

[0055] The invention relates to a network communication model, which is functionally divided into two different network entities: a large number of gateway nodes and a central dispatch system. The network security system is deployed on the gateway node, and they use the central scheduling to communicate with each other to find the URI information of the unidirectional flow they need.

[0056] figure 1 Shows the communication architecture diagram. Such as figure 1 As shown, there are multiple identical gateway servers (gateway A and B are one of the gateway servers), on which a network se...

Abstract

The invention provides a finding and correlation method for a one-way flow uniform resource identifier (URI) under asymmetric routing. A network comprises a plurality of peer-to-peer gateway nodes (A, B, C and D) and a center scheduling node (S), wherein a network security system based on content scanning runs on the peer-to-peer gateway nodes (A, B, C and D), and a URI relevant center schedulingsystem runs on the center scheduling node (S) which is used for scheduling each gateway node to solve the URI correlation problem. The plurality of gateway nodes (A, B, C and D) are in a peer-to-peerrelationship, and any one gateway node can be used as a URI inquiry request gateway node to issue a URI inquiry request to the center scheduling node (S); and any one gateway node can also be used asa URI inquiry response gateway node so as to process the URI inquiry request, search a local URI hash table and return a relevant URI to the center scheduling node (S). In the method, inquiry requestinformation is collected through the center scheduling node (S) and the inquiry request information is regularly spread to other nodes in bulk, thereby improving the inquiry efficiency of the URI, and reducing the logic complexity of strategy implementation of the gateway nodes.

Description

Technical field [0001] The invention relates to the technical fields of asymmetric routing, network flow identification, the association of request flow and response flow in a multi-machine HTTP session, and rapid sharing of URI information. More specifically, it relates to the identification of unidirectional HTTP traffic caused by asymmetric routing and the correlation between its request flow and response flow in a large-scale border network, and then to find the URI associated with the response flow. Background technique [0002] At present, network flow identification technology has become the focus of attention. Accurate and rapid identification of the types of network flow application layer protocols is of great practical significance for the current network operation and management, such as helping to deepen network flow engineering, network Research on capacity design and allocation, quality of service (QoS) control, network performance monitoring, abnormal root cause an...
