Problems solved by technology

[0003] The load balancing algorithm in the prior art is to use the four-tuple of IPv6 source IP, destination IP, source port number, and destination port number in the XOR Hash operation, but in the mainstream tunnel application scenario in the IPv6 transition technology, some tunnels outside Layer IP addresses rarely change, some tunnel IPv6 addresses only change some of the bit segments, and the rest of the bit segments do not change, and have specific meaning and content, directly used as operands for load balancing operations, the effect is not good

Abstract

The invention provides a load balance processing device applied to network management equipment. The processing device comprises a table look-up matching unit and a balance branching unit, wherein after receiving a message, the table look-up unit matches the message with a preset tunnel character table, and according to a data extraction rule corresponding to matched tunnel characteristics, operational data is extracted from the message; the balance branching unit calculates the extracted data according to a preset algorithm, and sends the message to a link corresponding to an obtained calculated result. The processing device disclosed by the invention can ensure a good load balance effect aiming at the main stream tunnel characteristics of an IPv6 transition technology.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a load balancing processing device. Background technique [0002] With the rapid development of the Internet, IP addresses are exhausted in many areas. In this case, IPv6 came into being and gradually replaced IPv4, but for the current widely used IPv4 network, the transition from IPv4 to IPv6 still needs a process, and the use of tunnel technology to complete the connection between IPv4 and IPv6 networks is also a transition Important technical means during this period. Load balancing is the optimization of network equipment, which increases the throughput of the network, strengthens the data processing capability of the network, and improves the flexibility and availability of the network. Therefore, how to perform load balancing in the environment of transition from IPv4 to IPv6 is an urgent problem to be solved. [0003] The load balancing algorithm in the prior...
