With reference to figure 1, show the flow chart of a kind of tunnel configuration method embodiment 1 of the present invention, can may further comprise the steps:
S101, a plurality of PE that provider edge node PE is divided into corresponding to business organize, and generate PE group division information;
In actual applications, can at first preset a PE group division rule, according to preset rules a plurality of PE that provider edge node PE is divided into corresponding to business be organized then.Wherein, preset rules can comprise: according to the historical professional preset rules that the use information of PE is formulated.Concrete execution mode has multiple, as: according to historical business the access times information of PE is formulated, if a certain business is under the situation of the certain number of times of transmission in the history, use the number of times of some PE to surpass a predetermined threshold value, then these PE are divided into one group of PE, corresponding to this business, can think that the corresponding PE of this business organizes the PE that often uses when interior PE transmits for this business.Certainly, also can formulate according to the historical professional efficiency information of using PE to transmit, higher as the efficiency of transmission of should business in the history using some PE to transmit, then these PE can be divided into one group, corresponding to this business, can think that the PE in the corresponding PE group of this business is the higher PE of this business efficient of transmission.Certainly, in actual applications, can also adopt other use information to formulate preset rules, the present invention does not do restriction at this.
Certainly, in actual applications, can also be divided into groups to the PE in the network according to analysis and professional requirement to communication network by the technical staff.As: professional 1 requires to send to PE2 from PE1, and a plurality of tunnels that connect the two will then can be divided into one group with PE1, PE2, PE3, PE4 and PE5 through PE3, PE4 and PE5, corresponding to business 1.
In addition, the PE group division information that generates of step S101 can be stored in the various memory devices.PE group division information can carry out upgrading in real time or regularly.
S102, according to described PE group division information, the professional corresponding PE that selects and be transmitted organizes;
It will be appreciated by persons skilled in the art that when service needed is transmitted the present invention just can find the PE group corresponding with this business according to this business.
Adapter path in S103, the described PE group of control between each PE generates a plurality of connection links;
Those of skill in the art would appreciate that after obtaining PE group division information system just can directly control in the professional corresponding PE group that is transmitted and connect between each PE, generates a plurality of connection links.Concrete, each the PE equipment in can organizing to identical PE sends bind command, controls between these PE equipment to connect.Ways of connecting has multiple, as connecting in twos or when distance between PE is not more than predetermined threshold value, then connecting.Certainly, also can allow each PE obtain PE group division information, control then in the corresponding PE group of this business and connect between each PE, generate a plurality of connection links.What need explanation a bit is that the tunnel belongs to and connects a kind of of link.
For allowing each PE obtain the mode of PE group division information, it will be appreciated by persons skilled in the art that each PE carries out data access to the memory device of storing PE group division information and just can obtain PE group division information.Certainly, the PE group division information of storing in the memory device can be sent among each PE yet, make each PE obtain PE group division information, the present invention does not do restriction at this.Concrete, PE group division information can be passed through Interior Gateway Protocol (IGP, Interior Gateway Protocols) and send among each PE.Interior Gateway Protocol IGP can have multiple, as: Intermediate System-to-Intermediate System (IS-IS, Intermediate System to Intermediate System) Routing Protocol and ospf (OSPE, Open Shortest Path First) agreement.Certainly, PE group division information also can pass through Border Gateway Protocol (BGP, Border Gateway Protocol) or other agreements send among each PE, and the present invention does not do restriction at this.
Need to prove, after obtaining concrete PE grouping information and corresponding business information, be between each PE of same group and just can connect, generate and connect link.Concrete, ways of connecting can have multiple, is connected as between: each PE and all PE of same group, and namely each PE connects in twos in the PE group, generates the connection link; Or for each PE, judge whether distance is not more than preset value between other PE of same group and this PE, if then this PE and distance are not more than between the PE of this preset value and are connected, and generate the connection link, otherwise do not connect.
It will be appreciated by persons skilled in the art that between the PE and can directly connect each other, generate the connection link, also can connect by the backbone equipment P of service provider, generate the connection link.When a PE connected another PE by different P, the connection link of its generation also was different.
S104, the use tunnel masterplate corresponding with this business are configured described a plurality of connection links, generate a plurality of tunnels;
Need to prove, can use the tunnel masterplate corresponding with this business that link parameter and/or the chain circuit function of described a plurality of connection links are configured.Certainly, also can other attributes that connect link be configured.Concrete, link parameter can comprise: bandwidth, priority and/or affine attribute; Chain circuit function can comprise: heavy-route FRR, backup label switched path LSP and/or auto-bandwidth adjustment fast.For helping to understand, below part of links parameter and part of links attribute are done simple the introduction.
It will be appreciated by persons skilled in the art that bandwidth is one of base attribute of MPLS TE.When the label switched path of setting up based on the constraint route (CR-LSP, Constraint-based Routed-Label Switched Path), the bandwidth that can specify MPLS TE, and determine suitable path according to bandwidth requirement.RSVP (RSVP-TE, Resource ReSerVation Protocol-Traffic Engineering) signaling based on the traffic engineering expansion can be carried bandwidth information, implements RSVP at each node along the path.After CR-LSP sets up successfully, can guarantee for corresponding service provides desired bandwidth.
To connect link in order better managing, can be link configuration priority.If in setting up the process of CR-LSP, can't find the path of satisfying required bandwidth requirement, then remove a certain the CR-LSP that priority is lower, take the bandwidth resources of distributing into it, this processing mode is called seizes (Preemption).
CR-LSP can use and set up priority (Setup Priority), keep two priority attributes of priority (Holding Priority) to determine whether and can seize.The value of priority can be from 0 to 7 integer.Value is more little, and priority is more high, and 7 is lowest priority.
Affine attribute is used for representing to connect the color of link.After connecting the affine attribute of link configuration, when service transmission system is selected to connect link, difference is connected the affine attribute of link and the link management group attribute that is connected of service transmission system compares, determine to select still to avoid the connection link of specific affine attribute.As after selecting a certain connection link that business is transmitted, can connect the different affine attribute of link with other for this connects link configuration, this business will be transmitted along the identical connection link of affine attribute like this, and avoid the different connection link of affine attribute, thereby realized connecting the selection of link.
Heavy-route (FRR, Fast ReRoute) is a kind of locality protection mechanism (also claiming TE FRR) in MPLS TE fast, for the protection of link and the node failure of CR-LSP, and can be to main LSP configured bandwidth protection or non-bandwidth protection.TE FRR walks around the link of fault by foundation in advance or the bypass functionality Bypass tunnel of node reaches the purpose of protecting main CR-LSP.When CR-LSP link or node failure, allow flow to continue from the bypass tunnel transmission, head node can be in the impregnable reconstruction that continues to initiate main path simultaneously of transfer of data simultaneously.
Backup label switched path LSP is widely used in TE, as: the CR-LSP that under the same paths main CR-LSP is carried out backing up in the path is called backup CR-LSP.Backup CR-LSP is used for realization to the traffic protection of important LSP.As an important component part of traffic protection, after main CR-LSP failure, flow need in time be switched on the backup path.When ingress perceives main CR-LSP when unavailable, flow is switched on the backup path, after recovering, main CR-LSP path again flow is switched back, to realize the backup protection to main CR-LSP path.
The auto-bandwidth adjustment can the detection of dynamic flow, and rebulids the path according to testing result according to the bandwidth demand of reality.
It will be appreciated by persons skilled in the art that above link parameter and chain circuit function are the part attribute of link, when this link during corresponding to different business, its part or all of attribute also may be different.For instance: in the time will transmitting the literal business, the bandwidth of its desired link is lower, at this moment only the band width configuration of link just can need be transmitted this literal business smoothly for lower bandwidth.And when the business that will transmit was video traffic, the desired link bandwidth of this business was higher, at this moment just need the band width configuration of link is higher, and to guarantee transmitting this video traffic smoothly.Certainly, it will be understood by those skilled in the art that other link attributes also can be configured to guarantee the smooth and easy transmission of this business according to the characteristic of want transport service, the present invention repeats no more.
