Embodiment Construction

[0100] Since the quintuples of each packet in the same service flow are the same, and the security service entries are usually established based on the quintuples of the packets, and the forwarding entries: FIB entries and ARP entries are also based on the quintuples of the packets. Based on the tuple, it can be known that the security service processing and forwarding processing for each packet of the same service flow are the same. Therefore, the core idea of ​​the present invention is: when the FIB entry is learned, the ARP entry corresponding to the FIB entry is searched, the first association relationship between the FIB entry and the ARP entry is established, and the first packet of the service flow is processed according to In the prior art, search for security service table items, FIB table items, and ARP table items is performed, and according to the search results, the attribute information of the package, the information of all security services that need to be perfo...

Abstract

The present invention discloses a method and a system for packet forwarding based on the security service. A first association relation between an FIB table and an ARP table is established; the firstpacket of the service flow is received, the corresponding security service information and the FIB table of the first packet are obtained, and a second association relation between the attribute information of the service flow packet carried by the first packet and the security service information and the FIB table are established; the follow-up packet of the service flow is received, and according to the attribute information of the follow-up packet and the second association relation and the first association relation, the security service information and the ARP table information are searched, the follow-up packet is processed with the security service according to the security service information, and the follow-up packet is forwarded according to the ARP table information. The presentinvention does not need to search the security service table and the ARP table of each packet, thus greatly improving the packet forwarding efficiency based on the security service.

Description

technical field [0001] The invention relates to the technical field of security services, in particular to a packet forwarding method and system based on security services. Background technique [0002] With the popularization and development of the network, the requirements for network equipment are not only simple fast forwarding, but also need network equipment to provide security services. This market demand promotes the development of security equipment, and puts forward the following requirements for security equipment: in the case of implementing security services such as security inspection and filtering on network data, it still provides relatively good forwarding performance. [0003] For security devices to meet the above requirements, it depends on the improvement of hardware performance, as well as the organization of software-related entries and the optimization of related business processes. How to organize related main entries and rely on them to improve pro...
