Embodiment
For making the present invention easier to understand, the present invention is further elaborated below in conjunction with accompanying drawing, but the embodiment in the accompanying drawing does not constitute any limitation of the invention.
As shown in Figure 1, the method for a kind of PBB-TE path management that the embodiment of the invention one provides may further comprise the steps:
PBB-TE path connection request is set up in step 101, reception, and the link-state information in the inquiry Ethernet.
When data flow need be set up the forwarding of PBB-TE path on Ethernet, server receives that the upper layer application layer of ethernet management system or Ethernet sends sets up PBB-TE path connection request, and by two layers of control protocol of Ethernet, such as the link-state information between a plurality of bridges in LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) the inquiry Ethernet.
Server calculates with described link-state information according to the described PBB-TE of foundation path connection request and sets up the routing iinformation that the PBB-TE path is connected, described routing iinformation comprises the explicit route information of the bringing into of from the source inlet bridge of forward-path to purpose outlet bridge/outbound port, and MSRP (resource registering agreement) message of setting up required Ethernet switched path.
Described explicit route information granularity is divided into two kinds of situations, and a kind of is outbound port information specific to each bridge, such as { node1:porta; Node2:portb; Node3:portb; Node4:porta; Node5}; Another is then only specific to each bridge address information, such as { nodel; Node2; Node3; Node4; Node5}.
Such as at first receiving described release PBB-TE path connection request when the source inlet bridge, just generate a promoter MAD_Leave announcement message send purpose outlet bridge to always along described route, notice each bridge on the way discharges the PBB-TE path; At first receive described release PBB-TE path connection request when purpose outlet bridge, just generate a recipient MAD_Leave announcement message send the source inlet bridge to always that notice each bridge on the way discharges the PBB-TE path along described route.
As Fig. 2, shown in Figure 3, the step 103 in the foregoing description one method can adopt different execution modes, and as first kind of execution mode, when the source inlet bridge in the Ethernet received described routing iinformation, its handling process was as follows:
Step 201, source inlet bridge receive described routing iinformation, generate first and connect the declaration signaling message, and along described route (as solid arrow direction among the figure) will as described in first connect the bridge transmission downstream of declaration signaling message.
Concrete, when source inlet bridge 1, it is edge inlet bridge, when receiving described routing iinformation, just generate first according to the explicit route information that comprises in the described routing iinformation and connect the declaration signaling message, promptly the promoter declares MAD_Join message, and this promoter declares that MAD_Join message is a kind of MSRP (resource registering agreement) message, comprise data flow ID, applicant ID, direction signs, declaration type, TSpec, the accumulative total time-delay, Frame parameter, Frame priority, rank can also comprise failure information.Wherein a MAC Address being associated by promoter's bridge of data flow ID adds that an integer constitutes, and integer described here is used for identifying the not homogeneous turbulence that same promoter's bridge sends; Applicant ID is used for mating the different MSRP announcement messages that constantly send of same port, applicant ID is made of port mac address and integer that bridge sends declaration, integer described here is used for distinguishing applicants different on the same MAC Address, it is unique that applicant ID requires same LAN to go up, and data flow ID then requires same bridged network unique; It is declaration of promoter's bridge or the declaration of recipient's bridge that described direction signs are used for identifying this declaration; Described TSpec is a transmission specifications parameter of describing stream, comprises bandwidth and frame speed; The Frame parameter, is made up of destination address and vlan sign with generating reserved address registering entities (Reserved Address Registration Entries) by bridge; Rank is used to refer to the importance of stream.
Described explicit route is at a connection, explicit route provide connection process hop-information and connect the condition that the jumping of process is satisfied, provide the information of all jumpings of connection process as explicit route.When explicit route during specific to the outbound port of each bridge, source inlet bridge 1 declares that with described promoter MAD_Join message issues bridge in the middle of the downstream from the outbound port of explicit route appointment.
Step 202, receive described first when connecting the declaration signaling message when downstream mid-level net bridge joint, record related data stream information, simultaneously self receiving port and mac address information being added to described first is connected in the declaration signaling message, continue then along route bridge forwarding downstream, until purpose outlet bridge.
Bridge (2,3,4) is receiving after described promoter declares MAD_Join message in the middle of the downstream, declare to generate a list item in the database (Registrar Declaration List) its Registrar, the information that record is relevant is such as data flow ID, applicant ID, direction signs, declaration type, TSpec, the accumulative total time-delay, the Frame parameter, Frame priority, rank etc.Declare that receiving described promoter the port of MAD_Join message and self bridge MAC Address add described promoter to and declare in the MAD_Join message in addition, the next bridge in explicit route is transmitted then, until purpose outlet bridge.
Step 203, receive amended successively described first when connecting the declaration signaling message when described purpose outlet bridge, carry out the record of associated upstream bridge MAC Address and transmit port, and generate the second connection declaration signaling message, return to upstream bridge (as dotted arrow direction among the figure) by former route.
Described purpose outlet bridge 5 receives the promoter and declares MAD_Join message, just generates second and connects the declaration signaling message, and promptly the recipient declares MSRP message, and it comprises data flow ID, applicant ID, direction signs, declaration type, information such as TSpec and accumulative total time-delay.Described purpose outlet bridge 5 declares that with the recipient MSRP message sends to the upstream bridge from the port that receives same data stream ID by former road.
Step 204, receive described second middle the bridge (2,3,4) that connects the declaration signaling message and declare that according to this signaling message carries out resource reservation, and the resource reservation result is added to described second connection declare in the signaling message, continue then to return to the upstream bridge, until described source inlet bridge by former route.
Step 205, when described source inlet bridge 1 receive amended successively described second connect the declaration signaling message after, result according to each downstream bridge resources reservation, judge whether whole Internet resources reserve success,, can transmit related data flow if then set up the PBB-TE path.
As Fig. 4, shown in Figure 5, be second kind of execution mode of the step 103 in the foregoing description one method.When the outlet of the purpose in Ethernet bridge received described routing iinformation, its handling process was as follows:
Step 303, receive amended successively described first when connecting the declaration signaling message when described source inlet bridge 1, carry out the record of associated upstream bridge MAC Address and transmit port, and generate the second connection declaration signaling message, return to the downstream bridge by former route;
Second kind of execution mode of step 103 compared with first kind of execution mode in the foregoing description one method, the described first connection declaration signaling message that generates is connected the declaration signaling message with second be the same, all adopt the target MAC (Media Access Control) address of the multicast address of the MSRP that keeps as described declaration signaling message, the difference part is at first to receive the edge bridges difference of described routing iinformation, and the direction that transmits the described first or second connection declaration signaling message is different.In the present embodiment first connects declares that signaling message is connected the declaration signaling message and only enumerates with second, also can comprise different contents in other embodiments, perhaps not that the promoter declares that MAD_Join message and recipient declare MSRP message, as long as can be used to set up the path according to route messages.
The method of the PBB-TE path management that the employing embodiment of the invention one provides, can concentrate and set up and the maintaining network topology, route between the centralized calculation connection end point bridge, needn't transmit each bridge respectively, the configuration of resource etc., and only need be at routing iinformation of edge bridges transmission of Ethernet switched path (ESP), use signaling to be connect forward-path between the end points bridge of data flow automatically, thereby make the data flow in the Ethernet have manageability, make Ethernet provide service quality (QoS for the user, Quality ofService) guarantees, traffic engineering can be made things convenient for, in Ethernet, realize simply.
