Problems solved by technology

[0022] The present invention describes a method for reasonably processing and forwarding PPPoE+ or DHCP Option 82 protocol messages in an EPON system, and solves the problem of excessive user bandwidth consumption and network congestion caused by the downlink broadcast of all or part of such protocol messages. Potential safety hazards and memory waste during message processing

Embodiment Construction

[0047] The invention provides a method for forwarding and processing the line identification message. In the OLT of the EPON system, by defining a reasonable array and data structure, the uplink protocol message is recorded and the relevant information is dynamically updated. The information includes the chip ID (address), PON slogan and LLID (logical link label) and so on. Ensure that the protocol packet processing of each request interaction of each user will not time out due to user record coverage and not forwarded downstream, and also ensure that each upstream location record of each user is up-to-date. In the downlink, the user record is searched through the user MAC address and chip ID. If the user record is found, set the downstream forwarding information with the recorded chip ID, PON port number and LLID number. When the destination MAC address of the downstream protocol packet is the broadcast MAC address, when the offer, ack, nack and other messages of the DHCP Op...

Abstract

The invention relates to a forwarding processing method of a line identification message. When an OLT of an EPON system receives an uplink protocol message reported by a user equipment, a management CPU of the OLT creates or updates a corresponding user according to user information in the uplink protocol message. record, to manage the destination MAC address and downlink forwarding information that match the user information; when the OLT receives the downlink protocol message from the server, the management CPU searches the recorded user MAC address and the target MAC address in the downlink protocol message. The user record with the same address, and the downlink protocol message is forwarded to the user equipment specified by the user record; when the destination MAC address in the downlink protocol message is a broadcast address, the management CPU replaces the broadcast address with the user record in the user record The unique unicast forwarding to the specified user equipment is realized, which solves the problem of excessive consumption of user bandwidth caused by broadcasting all or part of downlink protocol packets.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a new method for forwarding and processing line identification messages in an EPON system. Background technique [0002] For the EPON (Ethernet Passive Optical Network) system in which the PON (Passive Optical Network) service and switching service are processed by the PON chip, there are two methods for processing and forwarding the line identification protocol message: [0003] 1. PPPoE+ processing: [0004] The implementation process of PPPoE (point-to-point protocol based on Ethernet) includes the discovery (Discovery) phase and the session phase, and the line identification mainly handles the discovery phase. The discovery phase process is as follows: [0005] 1. The user host sends a PPPoE Active Discovery Initial (PADI) packet. The PADI package must contain at least one service name type (Service-Name) tag, which is used to provide the requested service to the acces...
