Multi-protocol-stack load balancing method and multi-protocol-stack load balancing device

Abstract

Disclosed in the present invention are a multiple protocol stack load balancing method and apparatus. The method comprises: creating a first socket in response to an application request, and deploying the first socket on all protocol stacks; receiving data packets requesting connection; judging the protocol type of the data packets requesting connection, and creating a second socket to establish a session connection if the protocol type is TCP; choosing one protocol stack for the second socket on the basis of the load condition of each protocol stack, creating a matching flow table on a network card on the basis of a shunt policy of the network card when the data packets of the second socket cannot be shunted, through a default shunt rule of the network card, to an RSS network card reception queue bound to the chosen protocol stack, and upon the reception of the data packets, shunting the received data packets of the second socket to the RSS network card reception queue; and completing data packets distribution between the second socket and the chosen protocol stack. By doing so, the present invention enables protocol stack load to balance and reduces the data distribution overhead of CPU in an environment of multiple protocol stacks by matching and combining load awareness of protocol stack and application with RSS network card reception / transmission queues and flow table.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-protocol stack load balancing method and device. Background technique [0002] With the rapid development of cloud computing, the computing work is more and more concentrated in the data center, and the terminal uses the network to quickly send the requested tasks to the data center, so the terminal's demand for computing power is decreasing, and the demand for The demand for network capacity is increasing. However, the protocol stack, as a bridge between applications and physical networks, has not been developed rapidly, and has gradually become a bottleneck between the two. It has become inevitable to combine multiple protocol stacks to handle single or multiple ports. At this time, a splitting algorithm should be used to forward the data packets belonging to the same connection to different protocol stacks. Since all protocol stacks share a distribution module...

Problems solved by technology

For example, usually the data packets sent through the firewall gateway have the same IP (Internet Protocol, network protocol). If the RSS distribution of the network card is only based on the source, destination IP and protocol triplet for hash (hash) distribution, these through The data packets of the same gateway are likely to be allocated to the same RSS network card receiving queue, which may cause the protocol stack connected to the queue to be overloaded.

Therefore, simple hash distribution based on triples / quintuples of data packets has the disadvantage of not being able to perform flexible load balancing distribution by sensing the real load situation of the protocol stack.
