Embodiment
For solving technical problem mentioned in background technology, the present invention proposes a kind of QoS processing method as shown in Figure 1, the method is applied in SDN the switching equipment building Overlay network, described SDN also comprises Open flow switch device, described Open flow switch device, by described Overlay network interconnection, comprises the steps:
S101, described switching equipment receives the encapsulated message with QoS operation requirements, and carry Open flow ID in described encapsulated message, described Open flow ID is uniquely corresponding with the QOS occurrence of described encapsulated message.
In order to enable the message of user side perform identical QOS operation when there is Overlay network in SDN in Openflow network and Overlay network, the present invention realizes this object by following two aspects:
On the one hand, Open flow switching equipment adds Open flow ID performed Meter operation according to the forwarding flow table of self to described encapsulated message before performing encapsulation operation to described encapsulated message after, wherein, the forwarding flow table of this Open flow switching equipment comprises the corresponding relation between the Open flow ID that issued to each QOS occurrence of described Open flow switching equipment, QoS action command and required interpolation.Wherein, QOS occurrence is the contents such as the MAC/VLAN/IP/L4 PORT in heading, and the QOS occurrence of the encapsulated message of different user is different.
On the other hand, before this step, switching equipment receives and the QoS that storage control issues forwards control table, described QoS forwards control table and is shown and the generation of stream table according to the Meter being issued to current all Open flow switching equipment by described controller, described Meter table comprises each QoS action command of issued Open flow switching equipment, described stream table comprises each QOS occurrence of issued Open flow switching equipment, corresponding relation between QoS action command and Open flow ID, described Open flow switching equipment generates forwarding flow table according to described Meter table and described stream table.
Above specific implementation process is by being distributed unitedly the Meter resource of network by controller, the flow control of crossing over Overlay network is achieved in SDN, but it is to be noted, issuing QoS at the controller switching equipment completed respectively to Overlay network forwards after control table and Open flow switching equipment issue Meter table and stream table, each QOS occurrence existing in the forwarding flow table of final current Open flow switching equipment is consistent with the corresponding relation that the corresponding relation between QoS action command and described QoS forward in control table between each Open flow ID and QoS action command.
S102, described switching equipment forwards in control table at the QoS self stored and inquires about the QoS action command whether mated with described Open flow ID, and described QoS forwarding control table comprises the corresponding relation between each Open flow ID of current existence and QoS action command.
S103, if there is the QoS action command mated with described Open flow ID, described switching equipment forwards described encapsulated message according to the destination address that described encapsulated message carries, and carries out QoS process according to described QoS action command to described encapsulated message.
In addition, after step, if the Meter table being issued to described Open flow switching equipment is deleted, then show the QoS action command comprised based on deleted Meter, the QoS deleting current all switching equipment forwards the corresponding relation comprising described QoS action command in control table.
In order to set forth technological thought of the present invention further, the existing application scenarios combined as described in Figure 2, is described technical scheme of the present invention.In this SDN, SW1, SW2 and SW3 are in Openflow network, these switches all support Openflow agreement, and the route between switch can reach the topological path that information safeguarded by controller completely and generate, and the forwarding information table in these switches comes from the stream table that controller issues.SW4, SW5 are in Overlay network, and these switches are by the control of Openflow agreement, by study route, network internal administration's Routing Protocol and two-layer protocol, guarantee that the IP in network can reach, and forwarding information table then comes from self Routing Protocol.In order to enable controller, response is made to the event of rolling off the production line on switches all in current SDN, create TCP interface channel between the switch of this specific embodiment in Overlay net and SDN controller, controller is by switch existing in this TCP interface channel perception Overlay network.
Based on above-mentioned network settings situation, this specific embodiment is divided into " mapping of QoS across a network " and " message coupling and forwarding " two large processes, is described in detail as follows:
One, QoS across a network maps
As mentioned above, Overlay network is there is between the Openflow switch in SDN, and time by Overlay network interworking, Openflow edge switch equipment is (as the SW1 in Fig. 2, SW3, connect the Openflow equipment of user network, lower same) Overlay net is entered to encapsulation tunnel head after user side message execution Meter operation, switch device on the way needs to identify this message having Meter operation requirements, because intermediate equipment only E-Packets according to tunnel head, the user's message of internal layer can not be identified, therefore need to be in progress to tunnel header, the attribute of unique identification sources Meter table is marked with one, in order to reach this object, controller must set up the QoS forwarding control table that an equity maps between Openflow net and Overlay network, and this mapping table is issued on the switch in Overlay network by safe and reliable TCP channel, the Meter operation performed at Openflow network side is unique to be mapped in message tunnel head, switch in Overlay network only needs to identify that the expansion mark in tunnel head just can perform the QOS control of identical Meter operation,
According to above-mentioned purpose, in controller in SDN is the service creation stream table of user side, if there is the requirement of QOS aspect, then in stream table, comprise Meter table index, comprise a Meter ID distributed in its action command, wherein multiple stream table can use the Meter of same Meter ID to show.Afterwards, controller can be also the QoS forwarding control table that in Overlay network, switch creates identical function, this QOS access control list contains occurrence and QoS action command, wherein occurrence is OpenFlow ID, OpenFlow ID uniquely identify in SDN the user's stream possessing certain QOS occurrence, because the extended field of the tunnel header of the channel message of the follow-up Overlay of entering network comprises OpenFlow ID at whole net.QoS action command then comes from Meter table, and this Meter is consistent with the Meter of original user Business Stream.
Particularly, as shown in Figure 2, controller is that switch SW1 is assigned with Meter table 1 and Meter table 2, for SW3 is assigned with Meter table 1, now must generate corresponding QoS and forward control table in whole Overlay network: Flow table 1 and Flow table 2, corresponding Meter table 1 and Meter table 2 respectively, when certain Meter in Openflow network shows deleted, Flow table corresponding in Overlay network also can be deleted.After QoS forwarding control table is issued to switch by TCP interface channel, switch returns the result creating list item to controller, whether rollback is shown for determining to show to this QOS relevant user's stream by controller during failure when returning results, the Overlay switch that there is QoS forwarding control table not only can E-Packet according to tunnel destination address, also will search QoS forwarding control table according to OpenFlow ID and carry out Meter operation.
Two, message coupling and forwarding
In this process, Overlay network will be entered after the message that user side enters SDN will forward on Openflow edge switch, if perform Meter operation, the mark of OpenFlow ID can be carried in the tunnel header of encapsulation, switch in Overlay network forwards according to destination address in tunnel header when receiving the message in this tunnel on the one hand, the QoS issued according to controller on the one hand forwards control table and mates, if matched certain OpenFlow ID, carries out traffic statistics and supervision according to the QoS action command of correspondence.
In addition, due to OpenFlow id field must be carried in tunnel header, therefore need to expand existing tunnel, if the tunnel that Overlay network adopts is VXLAN tunnel, then to use in VXLAN field reserved field as OpenFlow ID, if the tunnel that Overlay network adopts is IP gre tunneling, then uses the extended field in GRE head, reserved field is below used as OpenFlow ID.
In repeating process as shown in Figure 3, the message present Openflow edge switch SW1 of Business Stream 1 performs Openflow flow forwarding, carries out Meter operation, encapsulation tunnel head, and in head, comprise OpenFlow id field; Message enters Overlay network afterwards, after switch SW4 and SW5 on the way mates OpenFlow ID mark, perform Meter operation, now because Meter contents in table is identical with edge device SW1, therefore this message is identical with SW1 in the QOS action of intermediate equipment; When arriving the edge device SW3 of final jump, bullet falls tunnel header and again identifies user's message, performs Openflow flow forwarding, again performs Meter operation.In this way, the QOS occurrence of original message can be identified on equipment SW4 and SW5 source device SW1, Overlay network, object equipment SW3, makes the stream that there is Overlay network on whole path, all achieve identical Meter operation.
By the process of above-mentioned specific embodiment, in SDN, achieve the flow control of crossing over Overlay network, by the Meter resource of controller unified distribution network, optimize the flow control function of whole net.
