Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and the device that report switch type.
Background technology
Increasing disadvantage is exposed and the demand of people to network performance is more and more higher due to present network, researcher has to a lot of sophisticated functions to join in the middle of the architecture of router, such as ospf (OpenShortest Path First, be called for short OSPF), Border Gateway Protocol (Border Gateway Protocol, be called for short BGP), multicast, Differentiated Services, traffic engineering, network address translation (Network Address Translation, be called for short NAT), fire compartment wall, multiprotocol label switching (Multi Protocol Label Switching, be called for short MPLS) etc.This just makes the switching equipment such as router space that is more and more too fat to move and performance boost more and more less.
But distinct with the predicament of network field, computer realm achieves development with rapid changepl. never-ending changes and improvements.The development of careful review computer realm, is not difficult to find that its key is that computer realm have found a kind of simply available hardware bottom layer (x86 instruction set).Owing to there being a kind of so public hardware bottom layer, so in software, no matter be that application program or operating system all achieve development at full speed.Now much advocate that the personage redesigning computer network architectures thinks: the success that network can copy computer realm solves all problems that present network runs into.Under the guidance of this thought, network in the future will be such: data path such as switch, the router etc. of bottom are " mute, simple, minimum ", and define the public API about stream table of an opening, adopt controller to control whole network simultaneously.The API that following researcher just can call bottom on the controller freely programmes, thus realizes the innovation of network.
Based on above-mentioned theory, occurred software defined network (Software Defined Network is called for short SDN), it is that a kind of new network as shown in Figure 1 proposed by clean slate seminar of Stanford Univ USA innovates framework at first.At present, as shown in Figure 2, its core technology open flows (OpenFlow, being called for short OF) agreement is by separating network equipment chain of command (comprising OpenFlowController) and data surface (comprising OpenFlow Logical Switch), thus achieve the flexible control of network traffics, for the innovation of core network and application provides good platform.
OpenFlow agreement is used to the standard describing mutual information used between controller and switch, and the interface standard of controller and switch.The core of agreement is the set for OpenFlow protocol information structure.
OpenFlow flow table (Fig. 2) or form pipeline through multiple stream table cascade of layout and be used for configuration switch forward-path (Fig. 3), stream table clause is made up of following several fields such as matching field, counter and instruction set:
Wherein matching field (Match Fields) is the input keyword of message coupling, for mating a stream table clause; Counter (Counters) is the various statistical informations for managing; Instruction set (Instructions) refers to the operational order to message, comprises abandoning, the designated port that E-Packets, arranging header field value, increase encapsulated tags etc.Behavior aggregate (Action Set) and each message are associated, it transmit between multiple stream tables of pipeline and the instruction shown by each stream revise, until line treatment terminates, form final behavior aggregate.
As shown in Figure 3, step (1): the coupling stream entry finding limit priority; Step (2): application instruction: the territory of amendment message or renewal coupling; Update action collection; More new metadata; Step (3): matched data and behavior aggregate are sent to next stream table.
OF switch has defined two types in a standard: pure OF switch and mixed mode OF switch.For OF logical switch (OpenFlow Logical Switch, be called for short OFLS), the difference of two types is only, the latter needs to support NORMAL this reservation interface, makes OpenFlow flow table pipeline can by flow lead in the forward process flow process of traditional switch or router.
But current OF agreement does not define OF controller, and how perception OFLS is any type, it is mixed mode switch type that such OF controller may give tacit consent to OFLS, then issues some according to APP business demand and exports (output) to the stream table clause retaining interface " normal (NORMAL) ".
Although do not support that the OF switch of NORMAL is when the interface receiving output (output) is the stream table clause of NORMAL interface, mistake (error) message can be replied, carry the ofp_bad_action_code value of OFPBAC_BAD_OUT_PORT, but this needs controller to be that NORMAL carrys out comprehensive descision according to the interface of this error message and output, need to require that APP cancels this service request further simultaneously, flow process is more complicated, and the mode semantic ambiguity of this perception OF switch type, bad understanding.
OF controller finds that certain OFLS is pure OF switch (OpenFlow-only Switch), should refuse the stream table clause issuing output to NORMAL to it.
Fig. 3 a is the application architecture figure of OF configuration protocol according to correlation technique and OF agreement, OF collocation point configuration or obtain OF switch type after, correlation technique does not support OF collocation point by the type notification of OF switch to corresponding OF controller.
Cannot perception OF switch be the problem of the OF switch of any type for OF controller in correlation technique, not yet propose effective solution at present.
