Abstract

The invention discloses a universal GPON-OLT system inter-plate communication middleware system. Inter-plate communication middleware serves as network adaptive layers of all distributed-type node equipment in a GPON-OLT machine frame system to be installed in GPON control board cards and GPON business board cards. The GPON control board cards achieve dispatching of multiple GPON business board cards, complete issuing of user configuration commands, monitor the states of all the service business cards and process system alarming information. The GPON service business cards achieve operation of a GPON controller. According to the universal GPON-OLT system inter-plate communication middleware system, an IO multiplexing technology based on a TCP networking protocol is utilized, and through the combination of an event frame and a distributed message queue designed by an observer pattern and means like resource pools and zero copy, the high reliability and high performance of inter-plate communication are achieved, the concurrent processing capability of the system inter-plate communication is strengthened, the occupancy of resources is reduced, and channel jams which possibly occur are reduced.

Description

technical field

[0001] The invention relates to the field of computer communication, in particular to a general GPON-OLT system board-to-board communication middleware system. Background technique

[0002] 1. The commercial GPON system currently on the market uses a proprietary machine-machine interface for inter-board communication, and the communication between the GPON control board and the service board uses a customized interface, and the communication parties use a private protocol to achieve the purpose of message analysis; the board The inter-communication uses the proprietary machine-machine interface customized by the merchant. The sender and receiver in the system network nodes are highly interdependent and highly coupled. If another network device is added, the communication interface needs to be renegotiated and adjusted, which is not conducive to expansion.

[0003] 2. The GPON rack system with distributed deployment is adopted. The communication between the GP...

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] This embodiment provides a general high-reliability and high-performance GPON-OLT system inter-board communication middleware system design method, in order to solve the machine-machine interface that occurs in the distributed deployment process of the existing GPON-OLT rack system Scalability, inter-board communication reliability, and performance bottlenecks in the communication process.

[0035] The inter-board communication middleware in the present invention is installed in the GPON control board and the GPON service board as the network adaptation layer of each distributed node device in the GPON-OLT rack system. Among them, the GPON control board realizes the scheduling of multiple GPON business boards, completes the issuance of user configuration commands, monitors the status of each business board and processes system alarm in...
