Method and system for processing protocol packet

Abstract

The invention discloses a method and a system for processing a protocol packet, and relates to the technical field of communications. The method comprises the following steps: a service disc obtains the packet type after parsing the protocol packet sent by a main control disc; when the forwarding function of the sent protocol packet is at an enabled state, the service disc stores the protocol packet in the cache after preprocessing, and stores the packet storage information in the corresponding message queues, wherein each packet type corresponds to a message queue; at the same time or later,the preprocessed protocol packet is obtained from the cache and processed according to the packet storage information extracted from the message queues. The invention reduces the processing links, avoids the loss of the management protocol packet, and ensures that the configuration message and the event message are preferentially processed, which improves the communication efficiency and reliability of the service disc, and is beneficial to the maintenance and management of the operator.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and system for processing protocol messages. Background technique [0002] A passive optical network (Passive Optical Network, PON) system generally includes an optical line terminal (OpticalLine Terminal, OLT), an optical distribution network (Optical Distribution Network, ODN), several optical network units (Optical Network Unit, ONU) or optical network Terminal (Optical network terminal, ONT), unless otherwise specified below, ONU and ONT are collectively referred to as ONU. The OLT is connected to several ONUs through the ODN. The OLT is located on the network side, placed at the central office, provides network concentration and access, can complete optical / electrical conversion, bandwidth allocation and control of the connection of each channel, and has real-time monitoring, Management and maintenance functions. ONU is located on the user side, realizes th...

Problems solved by technology

Since the CPU of the service disk processes the received or to-be-sent management protocol messages sequentially, it takes a long time, resulting in low communication efficiency and poor reliability between the service disk and the main control disk, which is not conducive to the maintenance and management of the operator.

Especially when a large number of certain types of protocol packets are generated in the existing network, for example, flooding of multicast protocol packets will keep the CPU of the service disk busy processing this type of protocol packets, resulting in other types of protocol packets The file is not processed in time, or other types of protocol messages are lost, and in severe cases, even the communication between the service disk and the main control disk is interrupted
