Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to a signal degradation processing method. In the present embodiment, it is determined whether or not the signal degradation state has changed, based on the detected signal degradation state of the link; if the signal degradation state is judged to be changed, a first message carrying the changed signal degradation state is sent to the opposite terminal equipment in real time based on a preset first protocol; wherein the first protocol is the LLDP protocol.
The following describes the implementation details of the signal degradation processing method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
The embodiment of the invention can be applied to a receiving device in a link, namely the receiving device in the link executes the signal degradation processing method. In other embodiments, the signal degradation processing method provided in the embodiments of the present invention may also be applied to a transmitting device in a link, that is, the transmitting device in the link executes the signal degradation processing method.
As shown in fig. 1, the signal degradation processing method according to the present embodiment includes:
Specifically, the interface management module of the receiving device determines whether the signal degradation state has changed according to the detected signal degradation state of the link.
The signal degradation state of the link is detected based on a preset second protocol, which is different from the first protocol. The degradation detection means that the signal degradation or the signal degradation does not exist on the link is sensed through different detection modes; the degradation processing refers to a series of operations further performed after detecting that there is signal degradation, including degradation notification and link reselection. For example: the second protocol may be the y.1731 protocol, the CFMM protocol, etc. The signal degradation state can be obtained by counting the packet loss rate of the protocol message, when the second protocol is the Y.1731 protocol, the packet loss rate can be counted by the frame loss measurement message, and the signal degradation state can be obtained by comparing the packet loss rate with a set threshold value.
In a specific example, the signal degradation state can also be obtained by means of a Frame Check Sequence (FCS), which is known as a Frame end, i.e., a tail field of a protocol data unit (Frame) of a data link layer of a computer network, and is a 4-byte cyclic redundancy Check code. The detection principle is as follows: when a source node sends a data frame, calculating the FCS by the frame head and the data part of the frame, after the destination node receives the data frame, calculating the FCS again in the same way, if the FCS is different from the received FCS, considering that the frame has errors in the transmission process, and then selecting to discard the frame, and comparing the frame discarding rate with a set threshold value to obtain a signal degradation state.
In a specific example, the signal degradation state may also be obtained by means of Cyclic Redundancy Check (CRC), which is a fast algorithm for generating a short fixed bit Check code according to data such as a network data packet or a computer file, and is mainly used to detect or Check errors that may occur after data transmission or storage.
It should be noted that the signal degradation state of the link can be detected by the interface management module of the receiving device through the above method; the detection module of the receiving device for detecting data may also detect the data through the above method, and send the detected signal degradation state of the link to the interface management module.
And 102, sending the first message carrying the changed signal degradation state to opposite-end equipment in real time based on a preset first protocol. Specifically, the first protocol is an LLDP protocol, which is a basic two-layer link layer protocol supported by two-layer or three-layer switching routing devices of many manufacturers, and has high protocol stability and wide application range. A message generation module of the receiving equipment generates a first message carrying the changed signal degradation state based on a preset LLDP protocol, and sends the first message to the opposite terminal equipment in real time; the opposite terminal device of the receiving device is the sending device corresponding to the receiving device.
The data format of the first packet is TLV (Type/Length/Value) format. The structure diagram of the TLV data format in this embodiment is shown in fig. 2, where the TLV header defines a TLV general format for LLDP organization, and the TLV information string is 5 bytes. Wherein OUI is 00-1E-73 occupies 3 bytes, subtype is 1 occupies 1 byte, and status represents the signal degradation state of the link (2 is signal present state, 0 is no signal degradation) occupies 1 byte. For example: if the changed signal degradation state is that there is signal degradation, status is 2. It is noted that the TLV may also be in other formats as long as the basic requirements of the LLDP protocol are met.
In the prior art, the signal degradation sensing direction is only the port receiving direction, a sending end cannot sense the signal degradation of the sending direction of the sending end, the signal degradation state notification needs to periodically send a message for notification, and the message cannot be sent immediately for notification, so that the switching of a standby link or the convergence of a route is not timely enough, the service quality of a user is affected, and faults such as long-time data cutoff and the like can be caused in serious cases. Compared with the prior art, in the embodiment, whether the signal degradation state of the link changes is judged according to the received signal degradation state of the link, and if the signal degradation state changes, the first message carrying the changed signal degradation state is sent to the opposite-end device in real time based on the preset first protocol, so that the periodic waiting is not needed, and the time for the opposite-end device to perceive the signal degradation state in the sending direction of the opposite-end device is shortened.
A second embodiment of the present invention relates to a signal degradation processing method. This embodiment is substantially the same as the first embodiment, except that: in the present embodiment, the signal degradation state of the link detected this time is compared with the signal degradation state of the link detected last time, and it is determined whether or not the signal degradation state has changed.
As shown in fig. 3, the signal degradation processing method according to the present embodiment includes:
step 203 is similar to step 102 and will not be described herein.
Specifically, the signal degradation state detected last time is stored in the interface management module of the receiving device, and the interface management module of the receiving device compares the signal degradation state of the link detected this time with the signal degradation state detected last time, where the signal degradation state is the presence or absence of signal degradation.
In step 202, it is determined whether the signal degradation state has changed. If the signal degradation state has changed, step 203 is entered.
Specifically, the interface management module of the receiving device stores the signal degradation state detected last time, determines that the signal degradation state has changed if the signal degradation state of the link detected this time is different from the signal degradation data detected last time, and updates the signal degradation state detected last time to the signal degradation state after the change. If the signal degradation state of the link detected this time is the same as the signal degradation state detected last time, the signal degradation state is judged not to be changed, and the signal degradation state is kept unchanged.
After determining that the signal degradation state is changed, the signal degradation state detected last time is updated to the changed signal degradation state, and a specific flowchart is shown in fig. 4.
In step 2003, the signal degradation state detected last time is updated to the changed signal degradation state. For example: if the signal degradation state of the link detected this time is the presence of signal degradation, the signal degradation state is changed, and the signal degradation state detected last time is updated to the changed signal degradation state; if the signal degradation state of the link detected this time is that no signal degradation exists, the signal degradation state is not changed, and the signal degradation state is still that no signal degradation exists.
In this embodiment, the signal degradation state of the link detected this time is compared with the signal degradation state detected last time, and whether the signal degradation state of the link changes is determined, and if the signal degradation state changes, the first packet carrying the changed signal degradation state is sent to the peer device in real time based on the preset first protocol, without waiting for a period, so that the time for the peer device to perceive the signal degradation state in the sending direction of the peer device is shortened.
A third embodiment of the present invention relates to a signal degradation processing method. This embodiment is substantially the same as the second embodiment, except that: in this embodiment, if it is determined that the signal degradation state has not changed, the second message carrying the signal degradation state is sent to the peer device according to a preset period based on a preset first protocol. As shown in fig. 5, the signal degradation processing method according to the present embodiment includes:
And step 304, sending the second message carrying the signal degradation state to the opposite terminal device according to a preset period based on a preset first protocol.
Specifically, when the signal degradation state is not changed, the message generation module of the receiving device generates a second message carrying the signal degradation state based on a preset LLDP protocol, and sends the second message to the peer device according to a preset period, without sending the second message to the peer device in real time, thereby reducing the occupation of link broadband resources. The data format of the second packet is also TLV (Type/Length/Value) format.
It should be noted that the receiving device and the peer device may process the signal degradation state in the same manner. The preset period may be set as needed, and the embodiment is not particularly limited.
In a specific example, when the signal degradation state is not changed, the message generation module of the device does not generate message information, and further no message is sent to the peer device. The processing mode of the receiving device and the opposite terminal device for the signal degradation state is consistent.
In the embodiment, whether the signal degradation state of the link is changed or not is judged according to the received signal degradation state of the link, and if the signal degradation state is changed, the message generation module of the receiving device sends the first message carrying the changed signal degradation state to the opposite-end device in real time based on the preset first protocol without waiting for a period, so that the time for the opposite-end device to sense the signal degradation state in the self-sending direction is shortened; when the signal degradation state is not changed, the message generation module of the receiving device sends the second message carrying the signal degradation state to the opposite terminal device according to a preset period based on a preset LLDP protocol, and the second message is not required to be sent to the opposite terminal device in real time, so that the occupation of link broadband resources is reduced.
A fourth embodiment of the present invention relates to a signal degradation processing method. In this embodiment, a first message sent by an opposite-end device is received, and a signal degradation state of a link is obtained according to the first message; the first message is a message carrying the changed signal degradation state and sent in real time based on a preset first protocol when the opposite terminal equipment judges that the signal degradation state changes; judging whether the signal degradation state changes according to the signal degradation state; and if the signal degradation state is judged to be changed, taking the changed signal degradation state as the signal degradation state of the link.
The embodiment of the invention can be applied to the transmitting device in the link, namely, the transmitting device in the link executes the signal degradation processing method. In other embodiments, the signal degradation processing method provided in the embodiments of the present invention may also be applied to a receiving device in a link, that is, the receiving device in the link executes the signal degradation processing method.
As shown in fig. 6, the signal degradation processing method according to the present embodiment includes:
Specifically, the first protocol is an LLDP protocol, and a message analysis module of the sending device receives a first message which is sent by an opposite terminal device and carries a signal degradation state and is generated based on a preset LLDP protocol, and analyzes the first message to obtain the signal degradation state; the opposite terminal device of the sending device is the receiving device corresponding to the sending device. Specifically, the status value in the TLV data format of the first packet is analyzed to obtain the signal degradation state, for example: if status is 2, the signal degradation status is signal degradation is present; if status is 0, the signal degradation state is no signal degradation.
In step 402, it is determined whether a signal degradation state has changed. If the signal degradation state has changed, the process proceeds to step 403.
Specifically, the message analysis module of the receiving device sends the analyzed signal degradation state to the interface management module of the receiving device, the interface management module of the receiving device stores the signal degradation state received last time, if the signal degradation state of the link received this time is different from the signal degradation state received last time, the signal degradation state is determined to be changed, and the signal degradation state received last time is updated to the changed signal degradation state. If the signal degradation state of the link received this time is the same as the signal degradation state received last time, the signal degradation state is judged not to be changed, and the signal degradation state is kept unchanged.
And step 403, taking the changed signal degradation state as the signal degradation state of the link.
Specifically, if the signal degradation state changes, the interface management module of the receiving device uses the changed signal degradation state as the signal degradation state of the link. For example: if the signal degradation state of the link is that there is no signal degradation and the changed signal degradation state is that there is signal degradation, the presence of signal degradation is regarded as the signal degradation state of the link.
In a specific example, if the signal degradation state changes, the interface management module of the receiving device is further configured to change an alarm state of the link, where the alarm state is alarm or non-alarm. Specifically, the interface management module may advertise the signal degradation status of the link by generating data containing the alarm status. By changing the alarm state, the change of the signal degradation state of the link can be notified in an alarm manner.
In a specific example, when the alarm state is a non-alarm state, the method further includes: if the time for acquiring the second message sent by the opposite terminal equipment exceeds a preset period, changing the alarm state of the link; and the second message is a message which is generated to carry the signal degradation state based on a preset first protocol and sent according to a preset period when the opposite terminal equipment judges that the signal degradation state is not changed. When the time for acquiring the second message exceeds the preset period, the alarm state is changed, and the alarm state of the link can be changed in time when the second message cannot be acquired under the signal degradation state during sending.
In this embodiment, when the peer device determines that the signal degradation state changes, the peer device sends the first packet carrying the changed signal degradation state in real time based on the preset first protocol, so that the interface management module of the receiving device can obtain the state of the link in time.
