Problems solved by technology

Although the dual-plane switching system is simple in design and easy to implement, due to the need to pass through different switching planes, the business organization and scheduling are very inflexible, the scalability is poor, and there are defects such as high equipment power consumption and high OPEX
[0004] At the same time, for centralized POTN equipment, due to factors such as switch board density, power consumption, and cost, it is often only possible to use a single switch board, that is, a single-plane switching architecture to complete POTN service forwarding

Embodiment Construction

[0084] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0085] see figure 1 As shown, the embodiment of the present invention provides a POTN service forwarding system, including an Ethernet tributary board, a switching board and an OTN line board;

[0086] An Ethernet tributary disk, the Ethernet tributary disk is used to transfer the packet service received from the Ethernet to the switching disk in the uplink direction, and transfer the data packet received from the switching disk to the Ethernet in the downlink direction;

[0087] A switching board, the switching board is used to realize data interaction between the Ethernet tributary board and the OTN line board; the switching board includes at least two tributary side backplane ports connected to the Ethernet tributary board and at least Four line-side backboard ports connected to the OTN line tray; one of the branch-side backboard ports is ...

Abstract

The invention discloses a POTN service forwarding system and a forwarding method and relates to the technical field of POTN transmission. The system comprises an Ethernet branch disk, a switch disk and OTN line disks. POVE is instantiated to multicast in an up direction to realize bridging, packet services take the multicast as an outlet of an up direction service channel, and an OTN service takes the multicast as a source port interacting with an ODUK channel; the POVE is instantiated to VLANDOMAIN in a down direction to realize bridging, the OTN service maps a line side back plate port connected to the ODUK channel to the VLANDOMAIN, and the packet services take the VLANDOMAIN as a common physical port to complete classification processing of the packet services. The invention also discloses a POTN service forwarding method.

Description

technical field [0001] The invention relates to the technical field of POTN transmission, in particular to a POTN service forwarding system and a service forwarding, configuration delivery and protection method. Background technique [0002] POTN integrates the network functions of the optical layer (WDM), OTN and SDH layers, and the packet transport layer (MPLS-TP, ETH). Unified and flexible transport functions for various services such as packet, OTN, and SDH. [0003] Traditional POTN equipment is designed based on TDM (ODUk) / Packet dual-plane switching architecture, that is, packet and TDM (ODUk) services are forwarded through different switching boards. Although the dual-plane switching system is simple in design and easy to implement, due to the need to pass through different switching planes, the business organization and scheduling are very inflexible, the scalability is poor, and there are defects such as high equipment power consumption and high OPEX. [0004] At...
