Embodiment Construction

[0054] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. It should be noted that the implementation of the technology for associating unidirectional flow URIs under asymmetric routing according to the present invention is only an example, but the present invention is not limited to this specific implementation.

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

[0056] figure 1 An architecture diagram of communication is shown. Such as figure 1 As shown, there are multiple identical gateway servers (both gateways A and B are one of the gateway ser...

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, association of request flow and response flow in multi-machine HTTP session, fast sharing of URI information and the like. More specifically, it involves the identification of one-way HTTP traffic caused by asymmetric routing and the association of its request flow and response flow in a large-scale border network, and then finds out the URI associated with the response flow. Background technique [0002] At present, network flow identification technology has become the focus of attention. Accurately and quickly identifying the type of network flow application layer protocol has great practical significance for the operation and management of the current network, such as helping to deepen network flow engineering, network Research on capacity design and allocation, quality of service (QoS) control, network performance monitoring, anomaly root cause analysi...
