Embodiment 1

[0054] Embodiment 1. Fiber Channel Service Fault Delivery Method

[0055] Such as figure 1 As shown, this embodiment mainly includes the following steps:

[0056] Step S110, receiving the FC service (FC client signal input) based on 8B / 10B code input on the optical port;

[0057] Step S120, obtaining the rate level of the FC service (such as FC-x);

[0058] Step S130, according to the nominal rate of the rate level, use the local clock to generate a failure replacement signal based on 8B / 10B encoding for the FC business; the failure replacement signal is the same as the rate of the FC business;

[0059] Step S140, judge whether the FC service is invalid, when it is judged that the FC service is invalid (such as input signal loss or link failure, etc.), go to step S150, otherwise go to step S160;

[0060] Step S150, according to GMP, map the FC service to a low-order optical data unit (OpticalDataUnit, ODU) frame, then multiplex the low-order ODU frame to a high-order ODU fr...

[0077] Embodiment 2: Fiber Channel Service Fault Transmission Device

[0078] combine figure 1 In the illustrated embodiment one, image 3 The illustrated embodiment mainly includes a first receiving unit 310, a first acquiring unit 320, a first generating unit 330, a first judging unit 340, a mapping unit 350, and a first transferring unit 360, wherein:

[0079] The first receiving unit 310 is configured to receive FC services based on 8B / 10B encoding on the optical port;

[0080] The first obtaining unit 320 is connected to the first receiving unit 310, and is used to obtain the rate level of the FC service;

[0081] The first generating unit 330 is connected with the receiving unit 310 and the first obtaining unit 320, and is used to generate a failure replacement based on 8B / 10B encoding for the FC service by using the local clock according to the nominal rate of the FC service of the rate level of the FC service Signal, the rate of the failure replacement signal is the...

Embodiment 3

[0088] Embodiment 3: Fiber Channel Service Fault Delivery Method

[0089] Such as Figure 5 As shown, this embodiment mainly includes the following steps:

[0090] Step S510, receiving the OTU frame input on the line;

[0091]Step S520, demap the OTU frame to the high-order ODU frame, and demultiplex the high-order ODU frame to the low-order ODU frame, and then demap the low-order ODU frame according to GMP to obtain the 8B / 10B coded FC business;

[0092] Step S530, acquiring the rate level of the FC service input on the line;

[0093] Step S540, according to the nominal rate of the FC service of the rate level, use the local clock to generate a failure replacement signal based on 8B / 10B coding for the FC service, and the failure replacement signal is the same as the rate of the FC service;

[0094] Step S550, judging whether there is a fault in the line, when it is judged that the line is faulty, go to step S560, otherwise go to step S570;

[0095] Step S560, transmit th...

Abstract

The present invention discloses a fiber channel service failure transmission method and device, which overcomes the technical problem that FC service failure cannot be transmitted through GFP management frames in the prior art, wherein the method mainly includes: according to the nominal rate of the rate level of the FC service, Generate a failure replacement signal for the FC service; judge whether the FC service is failure; when it is judged that the FC service is failure, map the failure replacement signal and transmit it to the line. Compared with the prior art, the technical solution of the present invention uses the substitute signal to replace the failed FC service when the FC service input by the client optical port fails, and uses the substitute signal for the downstream GMP mapping process and service transmission, It ensures the transparent transmission of link faults to downstream links until the egress of the OTN network, thereby realizing the transmission of service faults.

Description

technical field [0001] The invention relates to the technology of fiber channel service (FC), in particular to a method and device for FC service failure transfer. Background technique [0002] With the development of communication systems, the Optical Transport Network (OTN) has gradually become the mainstream of the transmission network. More and more customer signals can be carried through the OTN network, and the Fiber Channel service (FC) is also one of them. For FC services based on 8B / 10B coding, there are FC-100 (1.0625G), FC-200 (2.125G), FC-400 (4.25G) and FC-800 (8.5G) according to different rate levels. different business. [0003] When the FC service input by the OTN network fails, it needs to be able to transparently transmit the failure to the downstream OTN network egress. In the traditional practice, FC services are usually encapsulated through the Generic Frame Procedure (GFP-T) in transparent mode defined by G.7041, and then mapped to the Optical Channel...
