Description

Communication link determining method and communication device Technical Field The present application relates to the field of communications technologies, and in particular, to a method for determining a communication link and a communication device. Background Dedicated traffic for optical transmission networks typically configures both the active and the standby communication links and requires that both the active and the standby communication links meet the same communication requirements, e.g. latency requirements. At present, the time delay is usually determined based on the road network distance of the node on the map, and the actual communication line arrangement related to the private line service is not considered, so that the time delay accuracy of the designed communication link is low, the communication difference between the main communication link and the standby communication link is easy to occur, and the operation of the private line service is influenced. Disclosure of Invention The application provides a method and a device for determining a communication link, which can improve the accuracy and the credibility of time delay of the determination communication link. In a first aspect, the application provides a method for determining a communication link, which comprises the steps of obtaining first information, determining a communication link between a first node and a second node according to the first information, wherein the communication link comprises I nodes, the communication link corresponds to I-1 communication time delays, the I communication time delays in the I-1 communication time delays are determined based on one of the following parameters, namely network measurement information between the I node and the i+1 node in the I nodes, optical cable time delays between the I node and the i+1 node in the I nodes, and position information of the I node and the i+1 node in the I nodes, wherein I is an integer greater than or equal to 2, and I is a positive integer less than or equal to I-1. According to the design, network measurement information, optical cable time delay and position information among nodes are introduced to calculate the time delay of a communication link, and compared with the existing road network distance, more information references are added to attach to actual communication line deployment related to special line service, so that the time delay accuracy and reliability of determining the communication link can be improved. In one possible design, the I-1 th communication delay is determined based on the network measurement information between the I-1 th node and the i+1 th node in case the network measurement information between the I-1 th node and the i+1 th node is acquired, and the I-1 th communication delay is determined based on the optical cable delay or the position information between the I-1 th node and the i+1 th node in case the network measurement information between the I-1 th node and the i+1 th node is not acquired. In the design, the priority corresponding to the communication delay is higher than the priority of the communication delay based on the optical cable delay or the position information, the actual measurement can accord with the actual communication line arrangement related to the special line service, and the accuracy and the reliability of the delay of the communication link can be improved. Optionally, it may be further configured that the priority corresponding to the communication delay determined based on the optical cable delay is higher than the priority determined based on the position information, for example, in a case where the optical cable delay between the I-th node and the i+1th node in the I-th node is acquired, the I-1 th communication delay is determined based on the optical cable delay between the I-th node and the i+1th node, and in a case where the optical cable delay between the I-th node and the i+1th node in the I-th node is not acquired, the I-1 th communication delay is determined based on the position information of the I-th node and the i+1th node. In one possible design, the confidence level may be set for different communication delay calculation modes. For example, the ith communication delay corresponds to a first confidence level when the ith communication delay is determined based on the network measurement information, corresponds to a second confidence level when the ith communication delay is determined based on the fiber optic cable delay, and corresponds to a third confidence level when the ith communication delay is determined based on the location information. It can be understood that the first confidence coefficient is higher than the second confidence coefficient, the second confidence coefficient is higher than the third confidence coefficient, and the confidence coefficient corresponding to the communication time delay calculation mode with high priority is high. The design is used
