Abstract

The invention discloses a networking method for a packet transport network (PTN) access node equipment chain and relevant equipment, which are used for solving the problem of resource utilization rate reduction in communication networks at different transport speed rates actually required in the uplink and downlink directions of the existing networking mode. The method comprises the following steps of: determining the uplink required speed rate and the downlink required speed rate corresponding to PTN access node equipment in the PTN access node equipment chain, and determining the uplink network node interface (NNI) number and the downlink NNI number required by the PTN access node equipment according to the determined uplink required speed rate, the determined downlink required speed rate and the NNI support transmission rate; configuring uplink NNI transmission uplink grouped data packets with the same number as the determined uplink NNI number and downlink NNI transmission downlink grouped data packets with the same number as the determined downlink NNI number; and building the optical fiber connection between the PTN access node equipment and the adjacent PTN access node equipment on the basis of the configured NNI.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a networking method for a PTN access node equipment chain in a packet transport network, a method for transmitting packet data packets, a networking device for a PTN access node equipment chain, and a PTN access node equipment. Background technique [0002] attached figure 1 It is a schematic diagram of a network structure of an existing packet transport network (PTN, Packet Transport Network). A base station eNodeB or a base transceiver station (BTS, Base Transceiver Station) is connected to the access ring through the PTN access node device, and then connected to the core network through the aggregation ring. Due to the limitation of geographical conditions when deploying the network, or the consideration of saving costs when deploying the network in areas with low traffic, quality of service (QoS, Quality of Service) priority, and security performance, the ...
