Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] figure 1 It is a schematic diagram of the forwarding plane model, describing the functions that the forwarding plane needs to complete. The forwarding plane mainly includes "service forwarding chip" and "forwarding chip driver", etc. Due to the high degree of customization of the network processor (NP), the "service forwarding chip" is generally undertaken by the NP chip. The "service forwarding chip" needs to complete the functions of service forwarding, discarded packet extraction, and packet loss cause marking.
[0027] Such as figure 2 As shown, the configuration processing method suitable for next-generation transmission and data equipment fusion provided by the present invention includes the following steps:
[0028] Step 1. Set up a decision node on each service processing module in the forwarding plane, and set a "packet loss cause ID" correspondin...

The invention discloses a configuration processing method suitable for next-generation transmission and data equipment fusion, which includes the following steps: respectively setting a judgment node on each service processing module in the forwarding plane, and setting and corresponding packet loss on the judgment node Cause ID corresponding to the cause of packet loss; the control plane pre-assigns unique packet IDs for packets with different attributes, and sends them to the forwarding plane along with the configuration; the forwarding plane uses the packet When the judgment node judges that the message needs to be discarded, it adds the packet loss cause ID of the decision node in the message, and imports it into the packet loss processing module for processing; the packet loss processing module records the corresponding discarding through the message tag ID and the packet loss cause ID Packet; through the control plane to realize discarded packet extraction and monitoring. The present invention greatly shortens the time for problem location.
Description
technical field [0001] The invention relates to a packet transmission network, in particular to a method for rapidly locating network faults of the packet transmission network. Background technique [0002] Packet Transport Network (PTN) supports a variety of bidirectional point-to-point connection channels based on packet switching services. It has end-to-end networking capabilities suitable for various fine-grained services. The business isolation function maximizes the management and utilization of fiber resources and ensures business security. Today, PTN has become an important networking form. [0003] During the process of configuring PTN services, if there is a service failure, the engineering staff usually locates the problematic site by querying the service traffic one by one, and then checks the configuration to determine the problem. However, this method of finding problems requires a lot of work and is not efficient. Contents of the invention [0004] The te...
