Embodiment Construction

[0028] In order to realize multi-core parallel processing and scheduling of data packets and service flows under high-speed links, the present invention provides a multi-core parallel network service flow load balancing method and system.

[0029] First of all, the terms used in the present invention are given as follows:

[0030] Service flow: refers to a five-tuple including the source IP, destination IP, source port, destination port and protocol of both communication parties.

[0031] Business Flow ID: The unique identifier of the business flow.

[0032] Service flow ID space: a collection of all service flow IDs.

[0033] Service flow ID subspace: a set composed of a part of service flow IDs after being divided by the scheduling core.

[0034] Packet capture device: refers to the device in the computer system that can provide packet data from the Internet to the user space, such as Ethernet network card, DAG card, etc.

[0035] Scheduling core: One or several cores in ...

Abstract

The invention discloses a multi-core paralleled network traffic load balancing method and a multi-core paralleled network traffic load balancing system, which can equally share network traffic load on processing cores of a processer according to the actual network loading condition. The system and the method mainly comprises the following steps: matching data packets in a network into the traffic; generating a traffic record according to a traffic spacial mapping mechanism to make the traffic uniformly mapped into an ID space; and according to the network loading condition, dividing the traffic space, and dispatching the traffic load to different processing cores by a dispatching core. The method utilizes the appeared multi-core technology to effectively meet the requirements on parallel processing and dispatching of the data packets and the traffic under high-speed links.

Description

technical field [0001] The invention relates to a network service flow load balancing method and system thereof. Background technique [0002] With the rapid increase in the number and scale of Internet users and the continuous increase in network bandwidth, how to improve the performance of network traffic analysis equipment to meet the challenges of current high-speed link development has become a major problem that needs to be solved urgently. [0003] The methods currently adopted mainly include: 1. Adopting a dedicated business flow analysis hardware platform: matching data packet business flow, data packet application protocol analysis and other services. But the implementation is more complicated and the cost is very expensive. At the same time, due to the fixed hardware structure and poor scalability, it cannot adapt to the current complex network situation. 2. Use the sampling method to reduce system overhead: In the process of service flow processing, the service...
