Abstract
The present invention provides a message shunting method for ensuring Transmission Control Protocol (TCP) connection proportionality, wherein the method comprises the steps of: establishing a shunting list based on quadruples, recording information of each quadruple and distributing flow sequence numbers for the quadruples; and searching the shunting list when an Internet Protocal (IP) packet arrives a network device, taking out the flow sequence number of a found quadruple to shunt the IP packet if the quadruple can be found out, and otherwise newly distributing a term for the IP packet in the shunting list and a flow sequence number if the quadruple can not be found out. The scheme provided by the invention can realize the network shunting, and thereby the loads of the devices are more proportional.
Description
Technical field
The present invention relates to field of Internet communication, be specifically related to the balanced message shunt method of a kind of assurance.
Background technology
In a lot of network processes environment,, therefore need input flow rate be assigned to a plurality of processing units and handle according to the disposal ability of back-end processing unit owing to there be the disposal ability of fan-in network interface bandwidth greater than single back-end processing unit.
The shunting process of the network equipment is to realize in the driver of equipment mostly in the prior art, just adopts software to realize that this implementation can increase the load of the network equipment, influences other professional disposal abilities.
Application number be 200910176725 patent disclosure a kind of message diversion processing method and device carries out the Hash computing according to the four-tuple of described message, obtains the VCPU of described message correspondence, also promptly shunts target.
Determine that the method for shunting target can guarantee the message number basis equalization that each stream is handled though adopt four-tuple hash value, but can not guarantee that tcp connects or the pseudo-harmony that connects of udp, and during the host process flow based on connecting Resources allocation, guarantee that the message harmony might not guarantee the harmony of load on host computers.
Summary of the invention
The object of the invention is to provide a kind of assurance balanced message shunt method, and basic thought is to shunt according to connection.
A kind of TCP of assurance connects balanced message shunt method, and step is as follows:
A, set up a shunting table based on four-tuple;
B, write down each quaternary group information and divide the flow sequence number;
C, when IP bag arrives the network equipment, search the shunting table, if can find this four-tuple, then take out the stream sequence number and shunt; Otherwise be that it newly distributes one in the shunting table, and distribute a stream sequence number.
First kind of optimal technical scheme of the present invention is: described stream sequence number divides timing can adopt the counter accumulate mode.
Second kind of optimal technical scheme of the present invention is: described stream sequence number divides timing can adopt random number way.
The third optimal technical scheme of the present invention is: described stream sequence number divides timing can also adopt the most idle shunting target of calculating of feedback according to the shunting target, distributes the most idle stream sequence number at every turn.
The 4th kind of optimal technical scheme of the present invention is: described four-tuple comprises source IP, purpose IP, source port, destination interface.
The present invention adopts this mode can realize that the load of network shunting device is balanced more.

Embodiment
The method that the technical program provides can realize shunting based on connection on the network equipment.Specific practice is to safeguard the shunting table based on four-tuple on the network equipment, the stream sequence number of record quaternary group information and this four-tuple correspondence in the table.This stream sequence number is set up at this four-tuple item, distribute when also promptly distributing for the first time, concrete distribution method can be that the mode that adopts counter to add up also can be to adopt the mode of random number, and these two kinds of methods can both guarantee to be assigned to the linking number basically identical of each stream substantially.When an IP bag arrival network equipment, at first search the shunting table, shunt, otherwise be that it newly distributes one in the shunting table, and distribute a stream sequence number if in table, can find this four-tuple then to take out the stream sequence number.
Claims (5)
1. one kind guarantees that TCP connects balanced message shunt method, is characterized in that:
Step is as follows:
A, set up a shunting table based on four-tuple;
B, write down each quaternary group information and divide the flow sequence number;
C, when IP bag arrives the network equipment, search the shunting table, if can find this four-tuple, then take out the stream sequence number and shunt; Otherwise be that it newly distributes one in the shunting table, and distribute a stream sequence number.
