Embodiment
First embodiment of the invention provides a kind of method that improves business data transmission quality, and this method obtains through the load flow on each bar network link of this network node by at network node link flow being detected.The dangerous threshold value of distributing according to the load flow of this link and for the business datum of this link transmission determines whether and need protect loaded service data on this link, if need, then loaded service data on this link is switched on the reserve link.
Before implementing this first embodiment, be that the active link that needs protection configures reserve link according to the FRR technology.According to client's demand,, distribute corresponding priority level for the business datum of different CoS (Class of Service, business-level).As, the priority level of special user's business datum is set to the highest; The priority level of the business datum of responsible consumer is set to inferior high; The priority level of the business datum of domestic consumer is set to the 3rd, by that analogy, and up to distributing corresponding priority level for all users' business datum.Afterwards, respectively according to link bandwidth and business datum priority level, for the business datum of different priority levels is distributed a dangerous threshold value, and the definition corresponding control strategies.As be that the business datum of first priority level is distributed the first dangerous threshold value, as 75% of link bandwidth; Control strategy regulation: when the link load flow surpassed the first dangerous threshold value, the business datum of first priority level was dodged this link; Be the vpn service data allocations second dangerous threshold value of second priority level, as 85% of link bandwidth; Control strategy regulation: when the link load flow surpassed the second dangerous threshold value, the business datum of second priority level was dodged this link, and the rest may be inferred.
The specific implementation process of first embodiment comprises following content as shown in Figure 1:
When execution in step 101, respectively on the node of each in network topology structure, the load flow of each interface of detection node; Load flow and topology of networks according to the interface of detected each node utilize Tomogravity (Gravity Models) technology, calculate the load flow of source node to each link between the destination node.
Load flow on each link that calculates can be preserved with the form of form, perhaps, generate corresponding discharge model figure, so that further analyze.
In the step 104, can be according to load flow and the bandwidth of source node to each link of destination node, the link of selecting the surplus resources maximum is as reserve link.Like this, the link that can avoid crowding.
In the step 104, also can in the alternative link that is current link configuration, select a reserve link, the business datum of transmitting on the current link is switched on the reserve link.
Can use the FRR technology that the business datum of transmitting on the current link is switched on the reserve link.
In the such scheme, in the time of can also reaching dangerous threshold value at the load flow on finding link, this link is carried out danger warning.
Be a kind of concrete application of first embodiment of the invention below, be illustrated in fig. 2 shown below,
User's border router CE1 transmits the vpn service data to destination node, i.e. user's border router CE2 as source node.
According to topological structure, the business data transmission link between source node and the destination node has 3: CE1-PE1-PE4-CE2 (for convenience of description, it being labeled as link 1), CE1-PE1-PE2-PE4-CE2 (for convenience of description, it being labeled as link 2); CE1-PE1-PE2--PE3-PE4-CE2 (for convenience of description, it being labeled as link 3).
Link 1 is assigned the bandwidth of 120Mbit/s, and link 2 is assigned the bandwidth of 110Mbit/s, and link 3 is assigned the bandwidth of 100Mbit/s.
Transmission is user 1 vpn service data on the link 1; Transmission is user 2 vpn service data on the link 2; The user's 3 of transmission vpn service data on the link 3.
The vpn service data of different user are carried out the CoS classification, and be the different control strategy of business datum definition of different priority levels.As, the priority level of user 1 vpn service data is for the highest, corresponding control strategies is: the load flow on link reach the first dangerous threshold value (as, link bandwidth 70%) time, then user 1 business datum is dodged this link 1; User 2 priority level for time high corresponding control strategies is: when link flow reach the second dangerous threshold value (as, link bandwidth 80%) time, then user 2 business datum is dodged this link 2; User 3 priority level is the 3rd, and corresponding control strategies is: when link flow reach the 3rd dangerous threshold value (as, link bandwidth 90%) time, then user 3 business datum is dodged this link 3.
Detect the load flow on CE1, PE1, PE2, PE3, last each interface of PE4, CE2, and according to the load flow of each interface and network topology structure as shown in the figure, calculate the load flow on 3 links between source node CE1 and the destination node CE2, as to obtain load flow on the link 1 be that load flow on 84Mbit/s, the link 2 is that load flow on 80Mbit/s, the link 2 is 60Mbit/s.
The load flow on the link 1 and the first dangerous threshold value are compared, the load flow on the link 2 and the second dangerous threshold value are compared, load flow on the link 3 and the 3rd dangerous threshold value are compared, find load flow on the current link 1 reach the first dangerous threshold value (as, link bandwidth 70%), then the link 3 of selecting the surplus resources maximum in link 2 and link 3 is as reserve link, and uses VPN FRR technology that user 1 business datum is switched to transmission on the link 3.
The employed dangerous threshold value of above-mentioned first embodiment also can be only according to being used for the bandwidth of link of service data transmission, set.Corresponding control strategies is: when the load flow on the link reached dangerous threshold value, then the business datum on this link need be dodged this link.
