Problems solved by technology

However, because it needs to be compatible with the original 802.3 Ethernet protocol, a very complicated protocol must be used to realize the compatibility of the access network protocol and the Ethernet protocol, and a complex protocol layer and functional structure have been added, which has a great influence on the hardware design and software process. have made high demands
More importantly, the backbone transmission network and access network are not considered in a unified manner, a unified routing and signaling exchange mechanism is not implemented, and the understanding of service quality indicators in the entire network is lacking, resulting in lower transmission efficiency and service quality indicators
In the future, the all-optical intelligent network will adopt the unified management and control platform of the universal multi-label switching protocol, and the scope of application of the above method is limited

Abstract

A method for realizing passive light network operation and management is that general labels of the general multiprotocol label exchange protocol are applied to realize data forward multiple addressing base, the labels are taken as the basis of data service sorting forward. The label exchange path is applied to realize the forward of direct user end to user end, the strengthened route protocol is used to realize uniform flow engineering of passive light network and back bone network, the strengthened signaling protocol is used to realize the uniform label distribution of the passive light network and back bone network and the network management structure is applied to realize a uniform network management platform of the passive light network and backbone network.

Description

technical field [0001] The invention relates to a method for realizing the operation and management of a passive optical network, in particular to a method for realizing the operation and management of a passive optical network by using a general multi-protocol label switching protocol. The technical field of access network used in optical communication. Background technique [0002] At present, optical passive access networks include asynchronous transmission mode passive optical networks, Gigabit Ethernet-based passive optical networks and Gigabit passive optical networks. These three technologies are the focus of current access network technology research. Although these three technologies already have international standards, and some products have come out, but they do not consider the close integration of the access network with the backbone network and Internet protocol services. The protocol is also more complicated, resulting in too much information unrelated to tr...
