Abstract

The present invention provides a PON port energy-saving method and an ONU supporting multiple LLID ONUs, wherein the method includes: receiving a sleep notification from an OLT; when the ONU works in a multi-LLID mode, judging whether all LLIDs of the ONU are required Enter the dormancy state, when all LLIDs of this ONU are required to enter the dormancy state, determine the total dormancy time of all LLIDs according to the dormancy time corresponding to each LLID, and the dormancy time is made up of dormancy start time and dormancy duration; Enter the dormant state within the above shared dormancy time, and close the PON port. The present invention can realize that the ONU with multiple LLIDs is simultaneously compatible with multiple LLID OLTs and single LLID OLTs.

Description

technical field [0001] The invention relates to an optical network unit (ONU) of an Ethernet-based passive optical network (EPON), in particular to a passive optical network (PON) port energy-saving method and an ONU supporting multiple logical link identifiers (LLID) ONUs . Background technique [0002] In the traditional EPON technology described in the IEEE802.3 protocol, at the MAC layer, one ONU supports one LLID. When used in the upper layer, the ONU will send a data from the LLID of the optical line terminal (OLT) to its own N different queues for processing. [0003] With the rapid development of IT technology and the increasing number of business types, the ONU supporting a single LLID can no longer distinguish a large number of emerging business types. Therefore, China Telecom's EPON technology will enable the ONU to support more business types. Each ONU is expanded to support 8 LLIDs, that is, each queue in the ONU corresponds to one LLID, and the OLT that suppo...
