The Processing Method of the Message Based on the In-band Network Telemetry Technology

With the innovation of business applications and the continuous growth of user scale, the network presents the characteristics of "high-speed, large-scale, multi access and unpredictable". The management and control methods and means of the traditional network have been difficult to solve the challenges of existing networks and future networks. Therefore, the network managers urgently need to subvert the monitoring and troubleshooting methods of the traditional network and put forward real-time and flexible measurement solutions that can deal with scenario use cases such as the network state measurement, network failure detection, fault location and recovery. Therefore, the paper proposes a system and method for how the In-band Network Telemetry (INT) technology of switching equipment is applied in complex public packet networks, to deal with scenario use cases such as the network state measurement, network failure detection, fault location and recovery. However, in a cross-domain network, it is difficult to implement the network telemetry in a cross-domain network. Therefore, this paper proposes a method to realize the network telemetry in the cross-domain network (the complex public packet networks) by using the tunneling technology to deal with scenario use cases such as the network state measurement, network failure detection, fault location and recovery.
