Background technology
General express network data analysis system is all adopt multiple-core server, each cpu core can be run the parallel processing of a process (or thread), current system is all that the traffic distribution that network interface card received by software is to the message buffer in each cpu core, in distribution procedure, require that the bi-directional data of same connection will be assigned in same process, Here it is homology chummage.In the applied environment of some complexity, the requirement of homology chummage also can be very complicated, can not to single connection, but to a network segment, that is, require all data distributions of certain network segment to 1 process.
The patent No. is " 200910136299.2 ", denomination of invention is a kind of method that the method for non-homogeneous chummage active-standby service resource separation " in grid network " discloses non-homogeneous chummage active-standby service resource separation in a kind of grid network, the steps include: that the service management module of 1. source nodes receives the foundation request of the first business, trigger routing calculation module and calculate route, signaling control module starts to set up the first business; 2. route flood module complete resource identification information upgrade; 3. the service management module of source node receives the foundation request of the second business, triggers routing calculation module and carries out router-level topology according to active-standby service resource separation strategy; 4. signaling control module starts to set up the second business; 5. route flood module complete resource identification information upgrade.The method of the invention, can the active and standby not homology of process but chummage, active and standby homology not chummage, the active and standby not homology active-standby service resource separation also not in chummage three kinds of situations, and can be applied in network that grid network and ring network form jointly, also may be used in the network that grid network forms separately, method reliability is high, good stability.
The patent No. is " CN200610086536.5 ", denomination of invention discloses a kind of load bridging method for " a kind of load bridging method and device ", comprising: set up synchronous between the base station belonging to each community overlapped each other; Base station detects that the current channel in either own cell cannot meet load request, and to the base station requests idle channel of the community with this little area overlapping, the idle channel mark that the base station of Bing Jiangge community returns sends to each shunting subscriber equipment.The present invention discloses a kind of load bridging device, comprising: synchronously set up module, load detecting module, Shunt Load community determination module and load bridging module.The invention solves the excessive and problem that frequency spectrum resource that is that cause is in short supply of cell load in wireless communication system; And the present invention can according to the idle channel situation of the community respectively overlapped each other, select Shunt Load community flexibly, Appropriate application frequency spectrum resource, and do not need to increase overhead.In addition, shunting subscriber equipment, before connecting with new community, can keep, with the connection of former community, ensure that the QoS of subscriber equipment always.
The method realizing homology chummage is generally that the source ip of message and object ip is done symmetrical bit arithmetic, when carrying out complicated homology chummage and calculating, because the mask of the network segment can be very flexible, generally realize in software, software to each message, after extracting ip, according to the requirement of homology chummage, do bit arithmetic after mask operation is carried out to ip, obtain the process number that message should be distributed to.
On express network, software calculates the homology chummage of each message, often becomes the bottleneck of system.
