Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inventors have analyzed the occurrence of link failures in a communication network. Fig. 1 shows a schematic diagram of a link normal situation and a link failure situation in a communication network. As shown in fig. 1, links 1, 2, and 3 are load balancing links in the same direction between two network devices. In the case of normal links, IP links 1, 2, 3 collectively carry the data flow between the two network devices.
In the related art, when a part of IP links in a load balancing link in the same office direction are interrupted or failed, due to the inherent characteristic of the shortest path algorithm adopted in the IGP protocol, these data flows are not switched to other links, but original data flows are carried by the link that has not failed, resulting in serious congestion of the link. For example, when IP links 2 and 3 fail, link 1 cannot completely carry all traffic of the original data stream, and a serious congestion and packet loss of the link occur.
In the disclosure, for the problem that a data stream cannot be switched to another link when a part of IP links in the same office direction fail, the inventor considers that when a failed link is higher than a certain proportion, the IP link 1 is blocked, and at this time, a path formed by the IP links 1, 2, and 3 is interrupted, and triggers the communication network to recalculate the path according to an algorithm of an IGP protocol, so that the data stream is shared to other offices upwards, and when the IP links 2 and 3 fail completely or partially, the IP link 1 is reopened so as to relieve the congestion condition when the failed link is not higher than the certain proportion.
Some embodiments of the disclosed link control method are described below in conjunction with fig. 2.
Fig. 2 illustrates a flow diagram of a link control method of some embodiments of the present disclosure. As shown in fig. 2, the present embodiment includes steps S201 to S203.
In step S201, the cooperative service orchestrator acquires link information of the load balancing link in the same direction between the two network devices through the IP network controller, and sets a link control threshold value for the load balancing link in the same direction according to the link information.
In step S202, the cooperative service orchestrator acquires, through the IP network controller, the fault link information of the load balancing link in the same direction, and determines the proportion of the fault link in the load balancing link in the same direction according to the link information and the fault link information.
In step S203, the cooperative service orchestrator determines whether the ratio of the failed link is greater than a link control threshold.
Executing step S204 under the condition that the ratio of the failed link is greater than the link control threshold value; in the case where the failed link ratio is not greater than the link control threshold value, step S205 is executed.
In step S204, the cooperative service orchestrator blocks a non-failed link in the load balancing links in the same direction through the transport network controller to trigger link reselection of the data stream, and then returns to step S203.
In step S205, the cooperative service orchestrator opens a non-failure link in the peer-to-peer load balancing link through the transport network controller to carry the data stream, and then returns to step S203.
In this embodiment, under the condition that the proportion of the faulty link in the load balancing links in the same direction is high, all the load balancing links in the same direction are blocked, so that link reselection of a data stream is triggered, the congestion condition of the link in the communication network can be effectively relieved, and congestion caused by the fact that a few non-faulty links bear the flow of the original data stream is avoided. Meanwhile, the embodiment does not change the structure of the data packet transmitted in the communication network, nor changes the control plane protocol adopted in the communication network, so the implementation is easy.
Further embodiments of the disclosed link control method are described below to introduce cases of controlling a link between any two network devices in a communication network.
Therefore, step S201 can be decomposed into steps S2011 to S2013.
In step S2011, the cooperative service orchestrator obtains link information of a load balancing link in the same direction between any two network devices through the IP network controller;
in step S2012, the collaborative service orchestrator groups load balancing links in the same office direction, where the load balancing links in the same group are connected to the same two network devices and have the same office direction, and the load balancing links in different groups are connected to different two network devices or have different office directions;
in step S2013, the cooperative service orchestrator sets a link control threshold for each packet.
Accordingly, step S202 can be decomposed into step S2021 to step S2023.
In step S2011, the cooperative service orchestrator acquires, through the IP network controller, the failure link information of the load balancing link in the same direction.
In step S2012, the collaborative service orchestrator determines a packet where the faulty link is located according to the link information and the faulty link information.
In step S2013, the cooperative service orchestrator determines the proportion of the faulty links in the group where the faulty link is located, according to the number of the faulty links in the group where the faulty link is located and the number of all links.
Correspondingly, in step S203, the cooperative service orchestrator determines whether the ratio of the failed link in the packet where the failed link is located is greater than the link control threshold set for the packet. When the ratio of the failed link in the packet where the failed link is located is greater than the link control threshold set for the packet, in step S204, the cooperative service orchestrator blocks the non-failed link in the packet through the transmission network controller; in step S205, the cooperative service orchestrator opens a non-failed link in the packet through the transport network controller, when the proportion of the failed link in the packet where the failed link is located is not greater than the link control threshold set for the packet.
In this embodiment, the identifier grouping and threshold setting of each load balancing link in the same local direction in the communication network are implemented through the cooperative service orchestrator. Under the condition that the proportion of the fault link in the group where the fault link is located is not greater than the link control threshold value set for the group, blocking the whole group of links; under the condition that the proportion of the fault link in the group where the fault link is located is not greater than the link control threshold value set for the group, the normal link is recovered; therefore, the congestion condition of the links in the communication network is further relieved, and the congestion condition caused by the fact that a few links which are not failed bear the flow of the original data flow is avoided. Meanwhile, the embodiment does not change the structure of the data packet transmitted in the communication network, nor changes the control plane protocol adopted in the communication network, so the implementation is easy.
