Embodiment one

Fig. 2 shows the flowchart of the embodiment of the networking optimization method of IP bearer network of the present invention, as shown in Fig. 2, this method comprises the following steps:

S201: For each CE router, establish a first transmission link between the CE router and the access router corresponding to the CE router through the first port of the CE router; establish a first transmission link between the CE router and other CE routers through the second port of the CE router. A second transmission link is established between the routers.

Wherein, the first port and the second port are distributed on different slots of the CE router. Specifically, use the first port as the uplink port of the CE router, and use the second port as the interconnection port of the CE router; then apply for the uplink and interconnection transmission link resources of the CE router, which are required to be distributed on different transmission planes above, so as to ensure that single-plane transmission failures will not cause the uplink and interconnection links of the CE router to be disconnected at the same time; the uplink and interconnection link pigtails of the CE router are placed through the first port of the CE router, on the A first transmission link (that is, an uplink) is established between the CE router and the AR router corresponding to the CE router, and a second transmission link is established between the CE router and other CE routers through the second port of the CE router. (that is, the interconnection link), and then joint transmission for link commissioning. Specifically, configure the commissioning IP address on the CE router and the AR router, such as: 192.168.0.1/30, and select a large packet (such as a data packet with a size of 1500KB) and a small packet (such as a data packet with a size of 128KB) as the long Ping test, observe that there is no packet loss in the link test within 10 minutes, then the link debugging is successful, otherwise, the link commissioning and troubleshooting will be performed after the joint transmission, until the link commissioning does not lose packets and the delay jitter meets the requirements. After successfully debugging the link, configure the port office data on the CE router and the AR router, thus completing the CE-AR, CE-CE dual-port network.

S202: For each access router, establish a third transmission link between the access router and the core router corresponding to the access router through the third port of the access router; A fourth transmission link is established between the ingress router and other access routers.

Wherein, the third port and the fourth port are distributed on different slots of the access router. The link debugging methods of the third transmission link and the fourth transmission link may be similar to the link debugging methods of the first transmission link and the second transmission link, and will not be repeated here.

In steps S201 and S202, since most of the original interconnection links are carried by POS links, POS ports cannot allocate sub-interfaces on physical ports due to technical reasons, and multiple sub-interfaces of a single port cannot be multiplexed to carry different services. Therefore, By adjusting the cutover of the interconnection link originally carried on the POS port to the newly allocated Ethernet link, the network withdrawal of the POS port and the POS link is realized, that is, the de-POSization of the interconnection link; at the same time, a single POS chain The parameters are modified on the transmission side and split into two Ethernet GE links. Therefore, it is only necessary to allocate new Ethernet GE ports on the CE router and the AR router, and interconnect them through two transmission Ethernet links to realize CE - Dual link optimization for AR uplink.

Wherein, as shown in Figure 3, the solid line part is the existing transmission link, and the dotted line part is the corresponding newly added first transmission link, second transmission link, third transmission link and fourth transmission link, CE router 1, AR router 1, AR router 2, and CE router 2 form a dual-port network, which implements CE-AR and CE-CE link capacity expansion and carries actual traffic. Through this networking method, the link-level networking protection of CE routers is realized, so when a single transmission channel fails or a board card of a CE router fails, it can be ensured that the CE router is still dual-node bearing services, which greatly reduces the Fault risk of paired CE routers disconnecting from the network at the same time. And through this networking method, in the case of a single board failure of the access router, because the two links of the AR-CR are deployed on different ports, the failure of a single board will only cause a single AR-CR If the CR link is faulty, there is still a transmission link that can carry services, the network can still be carried by a zigzag network, and services can still be forwarded through two ARs, thus improving the stability of the IP bearer network.

As shown in Figure 3, AR1-CR1 interconnection link 1 and AR2-CR2 interconnection link 1 are on the same transmission plane 1, AR1-CR1 interconnection link 2 and AR2-CR2 interconnection link 2 are on the same transmission plane 2, and AR1-CR2 interconnection link 2 is on the same transmission plane 2. AR2 interconnection link 1 and AR1-AR2 interconnection link 2 belong to transmission plane 3 and transmission plane 4 respectively. Wherein, the AR1-CR1 interconnection link 2 and the AR2-CR2 interconnection link 2 correspond to the above-mentioned third transmission link, and the AR1-AR2 interconnection link 2 corresponds to the above-mentioned fourth transmission link. When the transmission plane 1 of AR1-CR1 fails, and the failure of transmission plane 1 causes a single link failure of AR1-CR1 and AR2-CR2, the network structure of the IP bearer network can be maintained through transmission plane 2, transmission plane 3, and transmission plane 4. ZigZag bearing, will not cause business interruption.

In particular, as an improved implementation of the solution in this embodiment, when the paired CE routers and the paired AR routers are deployed in different computer rooms, all the uplinks of the paired CE routers are connected to the AR routers through transmission link channels. , there is a risk that the uplinks of the paired CEs will be disconnected due to transmission channel failures. By connecting the uplinks of CE1 and CE2 to one AR in the same computer room and another AR in a different computer room, the One plane between CE and AR in the equipment room is directly connected through bare wires, which is not affected by the transmission channel, and the other CE-AR link is carried by the transmission channel; after optimization, when the transmission channel fails, the same The CE-AR link in the computer room is normally carried, and the business can still be carried out safely through the AR/CE, so as to ensure that at least one CE-AR link is not affected by the cross-computer room transmission channel, which effectively improves the security of the network.

S203: Detect link quality of multiple transmission links in the IP bearer network, and obtain link quality detection results.

Wherein, as an improved implementation of the solution of this embodiment, before step S203, the method further includes:

According to the link aggregation protocol, link aggregation is performed on multiple transmission links in the IP bearer network to obtain a link aggregation group.

Specifically, link aggregation (Link Aggregation) technology simply aggregates multiple physical links into a logical link with higher bandwidth, and the bandwidth of the logical link is equal to that of the multiple physical links aggregated together. sum of bandwidth. The number of aggregated physical links can be configured according to service bandwidth requirements. Therefore, link aggregation has the advantages of low cost and flexible configuration. In addition, link aggregation also has the function of link redundancy backup. The aggregated links dynamically back up each other, which improves the stability of the network.

Further, as an improved implementation of the solution of this embodiment, step S203 further includes:

Detect whether there is packet loss in each transmission link in the link aggregation group;

Determine the link quality detection result according to the detected transmission link with packet loss.

S204: Determine the faulty link according to the link quality detection result, and process the faulty link.

Further, as an improved implementation of the solution of this embodiment, step S204 further includes: determining the transmission link with packet loss recorded in the link quality detection result as a faulty link, and The services of the link aggregation group are switched to other transmission links in the link aggregation group, and the faulty link is withdrawn from the link aggregation group.

Specifically, in order to realize rapid detection of link quality, on the basis of implementing CE-AR and AR-CR interconnection dual-link bearer through steps S201 and S202, by deploying BFD and SCTP detection technologies on the transmission link, when a problem occurs link, the BFD and SCTP detection technologies can quickly detect abnormal link packet loss, and realize millisecond-level detection of link quality degradation. When a link loses packets, the link will automatically exit the link aggregation group, services are carried by other normal transmission links of the link aggregation group to avoid service interruption.

Further, as an improved implementation of the solution of this embodiment, step S203 further includes:

Detect whether the bit error rate in multiple transmission links in the IP bearer network exceeds the preset bit error rate threshold;

According to the detected transmission link whose bit error rate exceeds the preset bit error rate threshold, the link quality detection result is determined.

Further, as an improved implementation of the solution in this embodiment, step S204 further includes:

The transmission link whose bit error rate recorded in the link quality inspection result exceeds the preset bit error rate threshold is determined as a faulty link, and link overhead is added to the faulty link so that the service is switched to another transmission link.

Specifically, when there are many bit errors in the transmission link but the BFD technology does not detect the failure of the transmission link, through the preset bit error rate threshold, when a transmission link in multiple transmission links is detected When the bit error rate exceeds the preset bit error rate threshold, it means that the business has been affected. By deploying the IGP bit error switching technology, the transmission link whose bit error rate recorded in the link quality detection result exceeds the preset bit error rate threshold The link is determined as a faulty link, and link overhead is added to the faulty link, so that the service is soft-switched to other normal transmission links. The whole process is unaware, and the service can be restored immediately without manual intervention, effectively greatly improved the quality of service bearer. The link overhead may specifically be a COST value, for example, the COST value is 10000.

Optionally, after the faulty link is determined, alarm information can also be generated and pushed to the operation and maintenance terminal, so that the operation and maintenance personnel on the operation and maintenance terminal side can find out the link failure and deal with it in time, thereby minimizing the impact on the business Impact.

By using the method provided in this embodiment, for each CE router, establish a transmission link between it and the corresponding access router and between it and other CE routers; for each access router, establish a transmission link between it and the corresponding Establish transmission links between core routers and other access routers, which improves the reliability of the IP bearer network structure. When transmission channels, links, equipment boards, ports, etc. fail, It can still effectively maintain the dual-node bearer, avoiding the risk of dual-route failure in the IP bearer network; at the same time, through the link quality detection and faulty link processing, the quality problems of the entire link can be quickly found and the response capability is improved.
