Problems solved by technology

However, under normal circumstances, whether it is OAM or BFD detection, it will put forward higher requirements on the processing performance of the equipment, and the occupancy rate of network bandwidth will also increase; and the detection cycle of this method needs 3.5 transmission cycles, that is, if the business is in Failure occurs within 3.5 cycles, and this method cannot accurately reflect the business status

application example 1

[0049] The application scenario of this application example is that the access side of the PE equipment loses the los fault. For example, image 3 , 4 As shown in , it is a schematic diagram of an los fault on the access side of the PE device. In this scenario, the implementation process of the method described in the embodiment of the present invention is:

[0050] Step 1, the local PE device determines that the access side los is faulty;

[0051] Step 2, the local PE device continuously sends 5 pseudowire packets with pseudowire control words to the peer PE device; wherein, when encapsulating the pseudowire packets, set the pseudowire control word First nibble=0001 (binary) , and set the lowest bit of the Flags field to 1;

[0052] Step 3, the peer PE device detects that the local PE device sends a pseudowire message on the current service path;

[0053] Step 4, the peer PE device extracts the pseudowire control word of the pseudowire message, and obtains the status of t...

application example 2

[0056] The application scenario of this application example is a linkdown failure on the access side of the PE device (the Ethernet port is not connected), such as Figure 5 As shown in , it is a specific schematic diagram of the linkdown fault on the access side of the PE device. In this scenario, the implementation process of the method described in the embodiment of the present invention is:

[0057] Step 1. The local PE device determines that the access side linkdown is faulty;

[0058] Step 2, the local PE device continuously sends 5 pseudowire packets with pseudowire control words to the peer PE device; wherein, when encapsulating the pseudowire packets, set the pseudowire control word First nibble=0001 (binary) , and set the third bit of the Flags field to 1;

[0059] Step 3, the peer PE device detects that the local PE device sends a pseudowire message on the current service path;

[0060] Step 4, the peer PE device extracts the pseudowire control word of the pseudo...

application example 3

[0063] The application scenario of this application example is the failure of the aggregation port on the access side of the PE device. For example, Image 6 As shown in , it is a schematic diagram of failure of the aggregation port on the access side of the PE device. In this scenario, the implementation process of the method described in the embodiment of the present invention is:

[0064] Step 1. The PE device at the local end determines that the aggregation port on the access side fails;

[0065] Step 2, the local PE device continuously sends 5 pseudowire packets with pseudowire control words to the peer PE device; wherein, when encapsulating the pseudowire packets, set the pseudowire control word First nibble=0001 (binary) , and set the second bit of the Flags field to 1;

[0066] Step 3, the peer PE device detects that the local PE device sends a pseudowire message on the current service path;

[0067] Step 4, the peer PE device extracts the pseudowire control word of...

Abstract

The invention discloses a method, device and storage medium for judging business service status. The method is applied to operator edge PE equipment, including: determining that the business service status at the access side of the PE equipment is abnormal; setting a pseudowire control word , so that it carries abnormal service status information, and sends a pseudowire message with the pseudowire control word to the peer PE device connected to this PE device; and when receiving the pseudowire message sent by the peer PE device When the message is sent, the business service status is judged according to the pseudo-wire control word of the pseudo-wire message. The method for judging the business service state based on the PW control word proposed by the present invention does not need to configure OAM or BFD, and directly judges according to the state of the PW control word, thereby saving network bandwidth and improving detection efficiency.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method, device and storage medium for judging business service status in the field of packet transmission. Background technique [0002] In a PTN (Packet Transport Network, packet transport network) network, the business service status refers to whether the business is in a normal working state or an abnormal working state. How to determine whether the business is normal, and how to quickly determine the cause of the fault when the business is in an abnormal state, are problems that need to be solved by the business service status determination method. [0003] For the determination of business service status, the existing methods need to be based on MPLS-TP (Multi-Protocol Label Switching Transport Profile, Multi-Protocol Label Switching Transport Application) OAM (Operation, Administration and Maintenance, operation management and maintenance) technology or BFD (Bid...
