Step S202, flow controller obtains business game.This business game is for the abstract of operation layer and describes, and is dynamically changeable.Business game abundant in content various, no longer exhaustive herein, for instance can be ensure that certain high-quality business is not congested.The acquisition mode of business game, for instance, flow controller can obtain business game by the Restful interface of north orientation from business management system, it is also possible to by management personnel's configuration service strategy on flow controller.
Step S204, flow controller generates stream table according to business game, is expanded with network virtual path action field in stream table.
Reference table 1, stream table such as includes matching domain, enumerator, action (or claiming instruction) field, it is also possible to include Priority field etc..Wherein, action field includes forwarding, abandoning, and the present invention also extends network virtual path action field, is used for indicating network virtual path information.
Table 1
Wherein, for including with data packet matched tuple in matching domain: inbound port, source MAC (MediaAccessControl, medium access control) address, target MAC (Media Access Control) address, ethernet type, VLAN (VLAN) mark, VLAN priority, source IP address, purpose IP address, IP agreement, IP type of service, TCP (TransmissionControlProtocol, transmission control protocol) or UDP (UserDatagramProtocol, UDP) source port, TCP or UDP destination interface etc..Utilizing this 12 tuple to carry out flow scheduling can make service traffics adjustment granularity thinner.
Step S206, stream table is handed down to network edge device by flow controller, in order to network edge device identifies service traffics according to stream table and forwards according to corresponding network virtual path.A kind of method, stream table can be handed down to network edge device by OpenFlow interface by flow controller, supports network virtual path action field according to this OpenFlow interface aforementioned.
The present embodiment is by centerized fusion mechanism, simplify network configuration management work, and flow controller generates stream table according to business game, real time down gives each network edge device, stream table is expanded with network virtual path action field, network edge device identifies service traffics according to stream table and forwards according to corresponding network virtual path, thus realizing service traffics Real-Time Scheduling, the adjustment response ratio of service distributing is very fast.
In step S204, flow controller generates the first of stream table according to business game and realizes method and include: flow controller determines service traffics match information and service traffics virtual path information according to business game, using service traffics match information and service traffics virtual path information as the content in the matching domain and network virtual path action field of stream table.
Wherein, service traffics match information includes ingress port information, source MAC address information, target MAC (Media Access Control) address information, ethernet type information, VLAN ID information, VLAN precedence information, source IP address information, purpose IP address information, IP protocol information, IP type of service information, TCP or UDP source port information, TCP or UDP destination interface information.Service traffics virtual path information includes label switched path information.Every kind of service traffics match information can be respectively added in matching domain in corresponding tuple type.
Such as, business game is that every IPv4 flow selects LSP1 (label switched path), every ipv6 traffic selects LSP2, then service traffics match information is IP protocol information, including IPv4 and IPv6, service traffics virtual path information is LSP information, including LSP1 and LSP2, then in stream table 1, the IP agreement tuple of matching domain is IPv4, and network virtual path action field is LSP1, in stream table 2, the IP agreement tuple of matching domain is IPv6, and network virtual path action field is LSP2.
In step S204, flow controller realizes method according to the second of business game generation stream table and includes: flow controller determines precedence information, service traffics match information and service traffics virtual path information according to business game, the content in using precedence information, service traffics match information and service traffics virtual path information as the stream Priority field of table, matching domain and network virtual path action field.

Such as, business game is that every IPv4 flow selects LSP1, every ipv6 traffic selects LSP2, and ensure that IPv4 flow is not congested as far as possible, then service traffics match information is IP protocol information, including IPv4 and IPv6, service traffics virtual path information is LSP information, including LSP1 and LSP2, then in stream table 1, the IP agreement tuple of matching domain is IPv4, and network virtual path action field is LSP1, and Priority field forwards prior to routing table for stream table, in stream table 2, the IP agreement tuple of matching domain is IPv6, and network virtual path action field is LSP2.
In step S204, flow controller generates the third of stream table according to business game and realizes method and include: flow controller generates stream table according to business game and network condition, namely generates stream table according to business game and in conjunction with current network condition.Specifically, flow controller determines service traffics match information and service traffics virtual path information according to business game and network condition, the content in matching domain using service traffics match information and service traffics virtual path information as stream table and network virtual path action field.Or, flow controller determines precedence information, service traffics match information and service traffics virtual path information according to business game and network condition, the content in using precedence information, service traffics match information and service traffics virtual path information as the stream Priority field of table, matching domain and network virtual path action field.
Such as, business game is for virtual LAN VLAN 1 and VLAN2, better delay guarantee is provided for VLAN1, then according to current network condition, planning has two strip label switching path LSP1 and LSP2, and wherein the link bandwidth of LSP1 is bigger, then LSP1 can be distributed to VLAN1 by network flow table strategy, LSP2 distributes to VLAN2, may further specify that the VLAN1 priority relative to VLAN2 is higher further, may further specify that the stream table of VLAN1 forwards prior to routing table further.Then in stream table 1, the VLAN ID tuple of matching domain is VLAN1, and VLAN priority tuple is that VLAN1 is higher than VLAN2, and network virtual path action field is LSP1, and Priority field forwards prior to routing table for stream table；In stream table 1, the VLAN ID tuple of matching domain is VLAN2, and VLAN priority tuple is that VLAN1 is higher than VLAN2, and network virtual path action field is LSP2, and Priority field can be not provided with.
As can be seen here, according to business game, if desired in conjunction with current network condition, it is possible to select the combination of a corresponding tuple or multiple tuple in matching domain plan as occurrence and dispatch service traffics.The particular content difference of business game then needs to select from matching domain adaptively corresponding tuple.12 tuples having at least aforementioned list in matching domain can be used to carry out flow scheduling, therefore relative to existing five-tuple scheduling scheme, it is possible to makes service traffics adjust granularity thinner.
