Embodiment Construction

[0031] A technical problem to be solved by the present invention is how to control the upstream service flow to be sent to the OLT only through the main link in the all-fiber protection system.

[0032] In order to solve the problems of the technologies described above, the basic idea of ​​the present invention is as follows:

[0033] The switch chip can set the STP (Spanning Tree Protocol, Spanning Tree Protocol) status of the port. The STP status of the port includes the following five types:

[0034] Disabled: disable the port;

[0035] Blocking: The port in this state does not forward data packets, but can receive STP configuration messages such as BPDU (Bridge Protocol Data Unit, Bridge Protocol Data Unit), cannot send BPDU, and does not perform address learning;

[0036] Listening (listening): The port in this state does not forward data packets, can receive and send BPDUs, and does not perform MAC (Media Access Control, Media Access Control) address learning;

[0037]...

Abstract

The invention discloses a method for implementing service control in an all-fiber protection system and a device thereof. The method comprises the following steps: determining a primary port and a standby port of a network node interface (NNI), setting the spanning tree protocol status of the primary port to be a forwarding state, and setting the spanning tree protocol status of the standby port to be a learning state; and processing board-to-board communication messages between a main control board and an Ethernet passive optical network (EPON) subcard by the mode of a bridge protocol data unit (BPDU) via a switching chip. In the invention, service flow only passes through a main link; and in addition, when changeover occurs between the main link and a standby link, the service flow can be rapidly switched between the main link and the standby link, thus reducing packet loss and enhancing protective performance.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and device for realizing service control in an all-fiber protection system. Background technique [0002] With the development of broadband access technology, operators are gradually accepting and deploying Optical Access Network (OAN) to provide users with faster speed and higher quality services. [0003] Ethernet Passive Optical Network (EPON for short) is an Ethernet-based passive optical access technology that follows the IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 8203.ah series of standards. EPON is developed from Ethernet technology and is suitable for carrying Ethernet-based services, such as broadband Internet access, VOIP (Voice Over Internet Protocol, Internet Voice Transmission Protocol), IPTV (Internet Protocol Television, Interactive Network Television) and other applic...
