Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
Middle attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is only
It is some embodiments of the present application, instead of all the embodiments.The application being usually described and illustrated herein in the accompanying drawings is real
The component for applying example can be arranged and be designed with a variety of different configurations.Therefore, below to the application's provided in the accompanying drawings
The detailed description of embodiment is not intended to limit claimed scope of the present application, but is merely representative of the selected reality of the application
Apply example.Based on embodiments herein, those skilled in the art institute obtained without making creative work
There are other embodiments, shall fall in the protection scope of this application.
Fig. 1 is a kind of structural schematic diagram of ERPS networking provided by the embodiments of the present application, as shown in Figure 1, in ERPS networking
In include two loops, one of loop is made of node device A, node device B, node device C and node device D
, another loop is made of node device C, node device D, node device E and node device F, wherein node device
Link between A and node device B is the RPL link of main ring, and the link between node device E and node device F is subring
RPL link is blocked, with subring in the normal situation of ERPS networking with the port of the RPL link connection of main ring
The port of RPL link connection is also to be blocked, so that main ring and subring be avoided to form the loop of closure.
By taking main ring as an example, after the link between node device C and node device D breaks down, node device C and section
Point device D is sending R-APS (Ring Automatic Protection Switching, looped network automatic protection switching) message
Before, can on the position of the Request/State of R-APS message increase for identify the message be SF (Signal Fail,
Signal Fail) message field information, such as: in Request/State field increased field information can with 1011, so as to
Node device A and node device B decontrols the port of obstruction using the SF message, to make RPL chain after receiving the SF message
Road conducting, and then makes main ring can continue to work normally, wherein SF message is periodicity sending, so as in node device C and
Before link between node device D does not restore, RPL link is always on state.
After the trouble shooting of link between node device C and node device D, in order to avoid main ring forms closed loop,
At this time node device C and node device D needs temporarily block respective port respectively so that node device C and node device D it
Between link still in blocked state, node device C and node device D does not retransmit SF message at this time, and node device C and
Each self-starting Guard timer of node device D, then respectively to node device A and node device B send NR (No Request,
Link-recovery) message, it is fixed that node device A starts WTR (Wait To Restore, Wait-to-Restore) after receiving NR message
When device, after WTR timer expiry, node device A blocks the port of itself and RPL link connection, and to node device B,
Node device C and node device D sends (RN, RB) (No Request, RPL Block, link-recovery, RPL obstruction) message, with
Node device C and node device D is set to decontrol the port of itself obstruction, so that node device B be made to block itself and RPL link connection
Port, the link-recovery between node device C and node device D is normal at this time, and RPL link is blocked again.
When the network environment of ERPS networking is normal, in each self-starting Guard timer of node device C and node device D
After (a kind of timer), no longer there is SF message in main ring, still, when the network environment of ERPS networking is poor, network can be deposited
Postponing, after each self-starting Guard timer of node device C and node device D, can still there is SF message in main ring at this time,
Also, if RPL link is by before blocking again, node device A and node device B have received the SF message of delay
(old SF message), can also decontrol the port of itself obstruction, at this point, main ring can be made to form closed loop, so as to cause the upheaval of network.
In order to reduce the probability for forming closed loop in ERPS networking, present applicant proposes a kind of message processing method, nodes to set
Standby, electronic equipment and readable storage medium storing program for executing, timestamp information when being broken down by increasing faulty link in SF message,
It is super in the arrival time for determining the SF message by being judged twice SF message after node device receives SF message
Shi Hou abandons the SF message, by the above method, advantageously reduces in the ERPS networking due to caused by network delay and forms closed loop
Probability, thus be conducive to improve ERPS networking stability.
The implementation of the application is described in detail below.
Embodiment one
Fig. 2 is a kind of flow diagram for message processing method that the embodiment of the present application one provides, as shown in Fig. 2, the report
Literary processing method applies the corresponding first node equipment of faulty link in ERPS networking, which includes following step
It is rapid:
Step 201, after generating Signal Fail SF message, add the faulty link in the SF message and break down
When timestamp information.
The SF message for carrying the timestamp information is sent to corresponding second section of the faulty link by step 202
Point device, so that the second node equipment is in the timing length information using the timestamp information, local timer and originally
After ground temporal information determines the arrival time time-out of the SF, the SF message is abandoned.
Specifically, SF message is to be set in ERPS networking after failure link by the node connecting with the faulty link
Standby to send in specific time, when network is normal, being in ERPS networking except the specific time is not in SF message
, but when network environment status is poor (network exist delay the case where), except the specific time in ERPS networking still
There may be SF message, wherein SF message has the function of making port blocked in node device to decontrol, therefore, in order to avoid
Since network delay forms closed loop, need to increase in SF message the timestamp information when faulty link breaks down, so as to
Other node devices can use the timestamp information after receiving the SF message to determine whether the SF message is current
Whether malfunctioning node the is sent and SF message is the SF message (that is: current failed old SF message) postponed.
It should be noted that in ERPS networking after failure link, corresponding two node devices of the faulty link: section
Point device 1 and node device 2, after regarding node device 1 as first node equipment, node device 2 can be used as second node
Equipment, naturally it is also possible to regard node device 2 as first node equipment, node device 1 is used as second node equipment, it may be assumed that with this
Two node devices of faulty link connection can all send SF message, and can receive the SF message of other side's transmission, save
When point device exercises the function of sending SF message, it can be exercised using the node device as first node equipment in node device
, can be using the node device as second node equipment, further when receiving the function of SF message, first node equipment and
Two node devices are the function distributions exercised according to it.
For example, as shown in Figure 1, after the link between node device C and node device D breaks down, node device C
SF message can be all sent before the link does not restore with node device D, so that node device A and node device B decontrol itself
The port of obstruction, so that RPL link is in the conductive state, when detecting that the faulty link can restore, node device C can face
When block itself the port C1, node device D can temporarily block the port D1 of itself so that the link continues to keep obstruction, this
When node device C and node device D will not all be further continued for send SF message will not be again in network if network is normal at this time
There is SF message, and after RPL link is blocked, node device C and node device D can just decontrol the port of itself obstruction,
But when if there is the case where network delay, before RPL link is not blocked, there are still SF messages in network, and can
It can be received by node device C and node device D, after node device C and node device D receive SF message, can decontrol
The port of itself obstruction causes net to make node device A, node device B, node device C and node device D-shaped at closed loop
Network upheaval.
In order to reduce the probability of above situation appearance, the link between node device C and node device D breaks down
Afterwards, node device C adds timestamp information when faulty link breaks down after generating SF message in SF message, and will
The SF message is sent to node device D, so that node device D judges whether to be node device C for this using the SF message
The SF message that faulty link is sent, and judge whether the SF message is the SF message postponed, to reduce node device A, node
Equipment B, node device C and node device D-shaped are at the probability of closed loop, and node device C can be used as first node equipment at this time, section
Point device D as second node equipment, meanwhile, node device D can also be added in the SF message of generation faulty link occur therefore
Timestamp information when barrier, and the SF message is sent to node device C, node device D can be used as first node and set at this time
Standby, node device C is as second node equipment.
After increasing timestamp information when faulty link breaks down in SF message, second node equipment root can be made
Determine whether the SF message is that current malfunctioning node is sent and whether the SF message is the SF report postponed according to the SF message
Text, to perform corresponding processing second node equipment according to judging result, to advantageously reduce in ERPS networking
The probability of closed loop is formed, and advantageously reduces ERPS networking and the probability of upheaval occurs, to be conducive to improve ERPS networking
Stability, simultaneously as being to increase timestamp information in SF message, there is no need to increase additional signaling, to be conducive to
Save signal resource.
About second node equipment in the timing length information and local zone time letter using timestamp information, local timer
After breath determines the arrival time time-out of SF, abandons explaining in detail for SF message and be described in detail subsequent, herein no longer in detail
Explanation.
It, can be in the optional TLV of the SF message when executing step 201 in a feasible embodiment
The field information for indicating the timestamp information is added in (Type/Length/Value, type/length/value) field.
Specifically, the field information of timestamp information can occupy 8 bytes, and in optional TLV field include 32 bytes,
Therefore the field information of timestamp information is added to optional TLV field, may not need and SF message is transformed, thus favorably
In the transmission cost for reducing signaling.
Embodiment two
Fig. 3 is a kind of flow diagram for message processing method that the embodiment of the present application two provides, as shown in figure 3, the report
Literary processing method applies the corresponding second node equipment of faulty link in ERPS networking, which includes following step
It is rapid:
Step 301, after receiving Signal Fail SF message, judge whether local timer overtime.
Step 302, when determining the local timer time-out, believed according to the timestamp that is carried in the SF message
Breath, the timing length information of the local timer and local time information, judge whether the arrival time of the SF message surpasses
When.
Step 303, when determining the arrival time time-out of the SF message, abandon the SF message.
Specifically, after a link breaks down in ERPS networking, other links it can also happen that failure (with Fig. 1
For, after the link between node device C and node device D breaks down, between node device A and node device C
Link may also can break down, alternatively, the link between node device B and node device D may break down), therefore
There may be the SF message sent for different faults link in ERPS networking, it may be assumed that the SF that second node equipment receives
Message may be what first node equipment was sent, or, it is also possible to what other node devices were sent, in first node equipment and
Before link between second node equipment will restore, first node equipment and second node equipment all can temporarily block itself
With the port of the link connection, and (such as: Guard timer, wherein first for this interim obstruction starting local timer
The local timer started in node device and second node equipment is synchronous in time), before the timer expires not
Any SF message can be handled, to avoid closed loop is formed, therefore after second node equipment receives SF message, needs to judge this
Whether ground timer is overtime, when determining local timer time-out, illustrates that the SF message received may be the SF report of delay
Text (at this time in order to avoid forming closed loop, needs to abandon the SF message), or is also likely to be new SF message (ERPS networking at this time
It is middle new faulty link occur, need to decontrol the port of itself obstruction immediately after local timer time-out, to guarantee
The normal work of ERPS networking), when determining that local timer has not timed out, illustrate that second node equipment needs continue obstruction certainly
Therefore the port of body when determining that local timer has not timed out, needs to lose SF message, determining that local timer is super
Constantly, it needs to carry out secondary judgement, to determine that the SF message is the SF message or new SF message of delay, to be tied according to judgement
Fruit carries out subsequent processing.
Since local timer has timed out, and the SF message postponed is different with the timestamp information in new SF message,
Therefore timing length information, timestamp information and the local time information of local timer be can use to judge arriving for SF message
It is whether overtime up to the time, if when reaching time time-out of SF message, illustrate that the SF message is the SF message of delay, if SF is reported
The arrival time of text has not timed out, and illustrates that the SF message is new SF message, in the arrival time time-out for determining the SF message,
Due to needing to continue to block the port itself temporarily blocked, need to lose the SF message, to advantageously reduce in ERPS networking
The probability of closed loop is formed, and advantageously reduces ERPS networking and the probability of upheaval occurs, to be conducive to improve ERPS networking
Stability.
It about the setting of first node equipment and second node equipment, is described in detail in example 1, herein no longer
It is described in detail.
In a feasible embodiment, Fig. 4 is another message processing method that the embodiment of the present application two provides
Flow diagram, as shown in figure 4, can be realized by following steps when executing step 302:
Step 401, using the timestamp information as initial time, using the timing length information as process duration, determine
Initial time information at the time of reached after the process duration.
Step 402 is compared the time information and the local time information, when the time information is earlier than institute
When stating local time information, step 403 is executed, when the time information is later than or is equal to the local time information, is held
Row step 404.
Step 403, the arrival time time-out for determining the SF message.
Step 404 determines that the arrival time of the SF message has not timed out.
Specifically, since the timestamp information in the SF message of delay is different with the timestamp information in new SF message,
Also, the timestamp information in new SF message relative to the timestamp information in the SF message of delay more preferably close to it is current when
Between, and since local timer has timed out, can be with timing length information using timestamp information as initial time
Cheng Shichang determines the time information that reaches of the SF message, then reaches time information using this and is compared with local time information
Compared with, when the arrival time information is earlier than local time information, illustrate the SF message be delay SF message, it may be assumed that the SF message
Arrival time time-out, when the arrival time information be later than or be equal to local time information when, illustrate that the SF message is new
SF message, it may be assumed that the arrival time of the SF message has not timed out, and in the arrival time time-out for determining SF message, illustrates this
SF message is the SF message of delay, in order to avoid formation closed loop, needs to abandon the SF message.
For example, as shown in Figure 1, the temporal information that the link between node device C and node device D breaks down
Are as follows: 10:00:00, the temporal information that the link between node device C and node device A breaks down are as follows: 10:20:00, wherein
Node device C is as second node equipment, in node device C, for the link between node device C and node device D
The timing length of local timer is 1 minute, and after local timer time-out, and there is still a need for continue to block the end C1 by node device C
Mouthful when, if the local zone time of node device C be 10:20:10, node device C receive be delay SF message
In the case of, information at the time of the timing length information of timestamp information and local timer in SF message can reach are as follows: 10:
01:00, information is earlier than local zone time at the time of the arrival of the SF message at this time, hence, it can be determined that the SF message is delay
SF message, node device C receive be new SF message in the case where, timestamp information and local timing in SF message
Information at the time of the timing length information of device can reach are as follows: 10:21:00, information is late at the time of the arrival of the SF message at this time
In local zone time, hence, it can be determined that the SF message is new SF message.
It should be noted that above-mentioned example is only the exemplary illustration to the embodiment of the present application, the application is not implemented
Example forms specific limit.
It, can be according to described when determining that the arrival time of SF message has not timed out in a feasible embodiment
SF message decontrols port blocked corresponding with the faulty link in the second node equipment.
Specifically, illustrating to be directed to when the SF message received at this time when determining that the arrival time of SF message has not timed out
The SF message that new faulty link is sent, it may be assumed that there is new link failure occur in ERPS networking at this time, and due at this time the
The local timer of two node devices has timed out, and second node equipment can handle SF message at this time, in order to make ERPS networking
Can work normally, need after second node equipment receives SF message at this time as soon as possible, decontrol in itself with faulty link
Corresponding port blocked.
For example, by taking Fig. 1 as an example, when node device C is as second node equipment, if node device C faces at this time
When block the port C1, and in node device C for the timer of faulty link between node device C and node device D
When overtime, after node device C judges the SF message received for the SF message for new faulty link transmission, need to put
The port C1 temporarily blocked is opened, node device D similarly decontrols the D1 temporarily blocked, so that recovery nodes equipment C and node are set
Link between standby D, to guarantee normal work that ERPS networking can continue to.
In a feasible embodiment, after executing the step 301, determining that the local timer do not surpass
Constantly, any SF message (SF message and new SF message including delay) cannot be handled by illustrating second node equipment at this time, this
When need to lose the SF message that receives.
