Specifically, due to introducing the detection of operation layer performance in embodiments of the present invention so that communications protection switching becomes For selection of the business to passage, thus it is particularly important that the detection of operation layer performance, therefore, in embodiments of the present invention, operation layer Performance detection uses Y.1731 technology and Y.1564 technology；Wherein, Y.1731 it is a kind of mode of business detection, it provides entity Discovery mechanism, entity continuity detection CC mechanism, and packet loss, time delay and shake mechanism are provided, and due to being Y.1731 business An attribute, so being generally used for the detection of the operation layer performance of main channel；Y.1564 it is one kind side of detection of activating the service Formula, can be detected the packet loss of business, time delay and shake index based on bandwidth test passage, so Y.1564 general use In the detection of the operation layer performance of standby passage.
It should be noted that either main side equipment, or from end equipment, configure Y.1564 terminal and Y.1731 hold Son；Also, if current business is on main channel when transmitting, main side equipment and Y.1731 terminal from end equipment are and main channel Association, main side equipment and the Y.1564 terminal from end equipment are associated with standby passage；Conversely, if current business is uploaded in standby passage When defeated, then main side equipment and Y.1731 terminal from end equipment are then associated with standby passage, main side equipment and from end equipment Y.1564 terminal is associated with main channel.
In addition, in main side equipment side, Y.1564 terminal and Y.1731 terminal is originating end, and from end equipment one Side, Y.1564 terminal is loopback end, is responsible for retransmiting away the message of reception, Y.1731 terminal is responder, for connecing Packet loss measurement response message (Loss is replied when receiving loss packet test message (Loss Measurement Message, LMM) Measurement Reply,LMR)。
However, step S303 in embodiments of the present invention is carried out after the configuration for determining passage is correct, so For the detection first of each passage, the state for detecting two passages is original state；Detecting the channel layer performance of two passages During with operation layer performance, channel layer performance is detected using the above-mentioned channel layer detection entity (BFD or CC) referred to, and business Layer performance is then generally detected using Y.1564 technology, i.e., the use of main side equipment Y.1564 technology with being handed over from end equipment Mutually, the service bearer quality testing of initial passage is carried out, forms initial operation layer performance；According to the channel layer detected With operation layer performance, the activestandby state of two passage can be determined.
Specifically, due to the detection of the operation layer performance that is Y.1731 generally used for main channel, Y.1564 it is generally used for standby logical The detection of the operation layer performance in road, therefore, in above-mentioned switching method provided in an embodiment of the present invention, sends to from end equipment After the notice for carrying the activestandby state for two passages determined, it can also include：By the main channel determined and business Enabled Y.1731 terminal is associated；By the standby passage determined, Y.1564 terminal is associated with service fulfillment detection；So as to fulfill Detection to the operation layer performance of main channel and standby passage, is conducive to provide quality of service index for protection switching, improves network To the perception of quality of service.
Also, before the activestandby state between switching main channel and standby passage, main channel and Y.1731 terminal phase Association, standby passage is associated with Y.1564 terminal, so after the activestandby state for determining main channel and standby passage needs to switch, Before the notice to the activestandby state that carrying switching main channel in need and standby passage are sent from end equipment, it can also include： Cut-out main channel is associated with Y.1731 terminal；The standby passage of cut-out is associated with Y.1564 terminal；It is active and standby so as to be advantageously implemented Passage respectively with Y.1731 terminal and Y.1564 terminal is associated, is realized and the operation layer performance of primary channel is examined again Survey.
Further, after the feedback message from end equipment is received, show to have distinguished primary channel from end equipment With Y.1731 terminal and Y.1564 the incidence relation of terminal is reset, i.e., has been completed each passage and each end from end equipment The association of son, so main side equipment can complete the switching of the activestandby state of primary channel, to ensure main side equipment with being set from end Normal communication between standby；Therefore, the step S206 switchings main channel in above-mentioned switching method provided in an embodiment of the present invention With the activestandby state of standby passage, can specifically include：Will be associated with Y.1731 terminal for passage；By main channel with Y.1564 holding Son is associated；Detected in real time so as to fulfill Y.1731 being transmitted to the business on standby passage, while by Y.1564 to main logical Road is monitored in real time.
For example, as shown in Figure 4 and Figure 5, Fig. 4 is each terminal before the master/slave switchover of primary channel and each passage Connection relation, Fig. 5 are the connection relation of each terminal after the master/slave switchover of primary channel and each passage；Wherein, 10 table Show Y.1564 terminal, 20 represent Y.1731 terminal, and 30 represent main channel, and 40 represent standby passage；Before handover, main channel 30 with Y.1731 terminal 20 is associated, and standby passage 40 is associated with Y.1564 terminal 10；After the handover, Y.1731 standby passage 40 with holding Son 20 is associated, and main channel 30 is associated with Y.1564 terminal 10, so as to fulfill the switching of the activestandby state of primary channel.
In the specific implementation, in order to be detected to the channel layer performance on primary channel and operation layer performance, with Determine the state of each passage, the performance of the step S202 detections main channel in above-mentioned switching method provided in an embodiment of the present invention With the performance of standby passage, can specifically include：
The operation layer performance to main channel and the operation layer performance of standby passage are detected in real time respectively, and according to default Business detection cycle exports testing result；
The channel layer performance to main channel and the channel layer performance of standby passage are detected in real time respectively, and determine to pass through master Passage and/or standby passage do not received within continuous three default Air conduct measurement cycles from the message that end equipment is sent when send out Go out warning.
Specifically, when to channel layer performance detection, realized using the above-mentioned traditional Air conduct measurement entity referred to, such as BFD or CC, and when being detected to channel layer performance, it is accomplished that real-time detection, with the state of abundant monitor channel；And And according to the regulation of BFD or CC, set if main side equipment is not received from end within continuous three default Air conduct measurement cycles During the message that preparation is sent, show channel interrupt, main side equipment and can not realize that normal business is transmitted from end equipment, because This, channel layer detection entity gives a warning immediately, so that switching system knows that main channel has been interrupted or standby passage has interrupted, The activestandby state of switching primary channel is needed, to ensure the normal communication of principal and subordinate's end equipment；Meanwhile if passage is always maintained at turning on State, then will not give a warning；Therefore, when detecting the channel layer performance of main channel and standby passage, if being examined in default business Survey in the cycle and do not give a warning, then it represents that passage is not completely deteriorated, if giving a warning in default business detection cycle, then it represents that Passage deteriorates.
Specifically, when carrying out operation layer performance detection, realization is also real-time detection, with the shape of abundant monitoring business layer State, since packet loss or time delay etc. are an accumulated times as a result, being detected so needing periodically to export, rather than output in real time Testing result；It should be noted that since the testing result of operation layer performance is exported according to default business detection cycle, So can be in operation layer performance test results of every output, whether the joint passage layer detection entity gives a warning, and true The fixed activestandby state for once whether needing to switch main channel and standby passage, so as to fulfill effective prison to main channel and standby passage Control, ensures main side equipment and from the normal communication between end equipment.
Therefore, in above-mentioned switching method provided in an embodiment of the present invention, exported according to default business detection cycle During testing result, default business detection cycle is determined using the following formula：
Tai=(t/a)+i × [t/ (a-1)-t/ (a)]/(2 × N), a is the integer more than 1；
Tai=t+i × (t/2)/(2 × N), a=1
Wherein, t represents measurement window, and Tai represents that i-th of class of business is corresponding default in a grades of the grade of service Business detection cycle, N represent class of business total quantity in a grades of the grade of service.
Specifically, measurement window is usually definite according to the time from network failure to network recovery, usually For 300 seconds, certainly, however it is not limited to this, it is merely illustrative herein；The grade of service is definite (industry according to the species of business Business grade can be represented with numerical value, and the bigger expression grade of service of numerical value is higher；Such as, the grade of service can be generally divided into 8 etc. Level, 8 represent grade of service highest, and 1 represents that the grade of service is minimum), in embodiments of the present invention, can be by the grade of service come area Divide the detection time of different business species, and the detection time of the different business inside the same grade of service, wherein, business etc. Level is higher, and the ratio of measurement window t and grade of service a is just smaller, represents that the high grade of service is more sensitive to quality of service, energy The change of enough quick response passages, rapidly switches to another passage, to ensure being normally carried out for business；Therefore, above-mentioned t with The ratio of a, can represent that business cannot switch at the same time, and have to progressively switch, to avoid face is still wanted after switching at the same time Face the situation appearance for tying up mutually, disturbing, so as to avoid the quality of service in passage not up to standard, and shake back and forth with preventing business Swing.
Also, in real network, there are multiple business transmission, each business is corresponding with corresponding service protection logic (specific visible herein below), and main channel and standby passage；For each business, operation layer is carried out under this kind of business Performance detection and channel layer performance detection, based on testing result perform determine this kind of business under primary channel active and standby shape The switching of state；Wherein, different business species is different on the default business detection cycle of operation layer；It may be noted that That main channel is generally used for transmitting real business, and standby passage be generally used for transmission simulation with corresponding main channel The identical artificial service of actual services.
For example, if measurement window t is 300 seconds, when grade of service a is 8, and i × [t/ (a-1)-t/ is determined by calculating (a)] when/(2 × N) is 4, the ratio of measurement window t and a are：T/a=300/8=37.5 seconds, thus the grade of service be 8 it is pre- If business detection cycle be T=37.5+4=41.5 seconds；If grade of service a is 1, and definite i × (t/2) of process calculating/ When (2 × N) is 0.5, the ratio of measurement window t and a are：T/a=300/1=300 seconds, thus the grade of service be 1 it is default Business detection cycle is T=300+0.5=300.5 seconds.Certainly, it is merely illustrative herein and how determines Tai, but is not limited to This.
According to above-mentioned example, it is low that the high default business detection cycle of the grade of service will be far smaller than the grade of service Default business detection cycle so that the high business of the grade of service can rapidly perceive the change of quality of service, can be quick Selection and switching of the business to passage are realized in ground, and decision-making is carried out to passage so as to fulfill according to business, when realizing passage switching, Meet the requirement of business, improve the service ability and open ability of network.
In the specific implementation, step S203 in above-mentioned switching method provided in an embodiment of the present invention is according to detecting The performance of the performance of main channel and standby passage, it is determined whether need to switch the activestandby state of main channel and standby passage, can be specific Including：
Whether the channel layer performance and/or operation layer performance for the main channel for determining to detect deteriorate；
In the channel layer performance and not completely deteriorated operation layer performance for the main channel for determining to detect, it is not necessary to which switching is main logical The activestandby state in road and standby passage；
In the channel layer performance and/or operation layer performance degradation for the main channel for determining to detect, determine to detect standby Whether the channel layer performance and/or operation layer performance of passage deteriorate；
In the channel layer performance and not completely deteriorated operation layer performance for the standby passage for determining to detect, it is necessary to switch main channel With the activestandby state of standby passage；
In the channel layer performance and/or operation layer performance degradation for the standby passage for determining to detect, it is not necessary to which switching is main logical The activestandby state in road and standby passage.
Specifically, in above-mentioned switching method provided in an embodiment of the present invention, channel layer performance degradation is：The state of passage For interrupt status；Operation layer performance degradation is：The numerical value of operation layer performance is more than predetermined threshold value.Wherein, predetermined threshold value can root It is configured, is not limited thereto according to specific actual conditions.
Specifically, as shown in fig. 6, showing the switching between each state of primary channel, wherein, master is up to standard to refer to passage Layer performance and operation layer performance are not completely deteriorated, and main not up to standard refer to channel layer performance and operation layer performance at least one is bad Change；Similarly, refer to that channel layer performance and operation layer performance are not completely deteriorated for up to standard, and refer to channel layer performance and industry for not up to standard At least one deterioration of layer performance of being engaged in；Also, the passage that P represents carry out business transmission is defined, then P is associated with Y.1731 terminal, Q Represent the passage transmitted without business, then Q is associated with Y.1564 terminal.
For example, after by the channel layer performance and operation layer performance of two passages of detection in above-mentioned steps S303, determine The performance of main channel is up to standard, when the performance of standby passage is also up to standard, is denoted as state 1, at this point it is possible to main channel is determined as passage P, Standby passage is passage Q, i.e. business is transmitted on main channel.
When the performance degradation of standby passage, state 2 is switched to by state 1, i.e. the performance of main channel is up to standard, the performance of standby passage It is not up to standard；Since the performance of main channel is still up to standard, so business can still be transmitted on main channel, it is not necessary to cut Change, so main channel is still passage P, standby passage is still passage Q.
When the performance degradation of main channel, state 3 is switched to by state 1, i.e. the performance of main channel is not up to standard, the property of standby passage Can be up to standard, at this time since main channel deteriorates, cause business can not be transmitted on main channel, so business is transmitted just on standby passage It can guarantee that main side equipment and the normal communication from end equipment, therefore, standby passage is passage P, and main channel is passage Q.
When the performance degradation of main channel, when the performance of standby passage also deteriorates, state 4 is switched to by state 2, or by state 3 when switching to state 4, i.e. the performance of main channel is not up to standard, and the performance of standby passage is not up to standard, even if being switched at this time to passage It cannot be guaranteed that the business transmission between principal and subordinate's end equipment, so maintaining the state of current each passage.
Certainly, after the channel layer performance and operation layer performance by detecting two passages in above-mentioned steps S303, determine The performance of main channel is not up to standard, when the performance of standby passage is up to standard, or by detecting the passage of two passages in above-mentioned steps S303 After layer performance and operation layer performance, determine that the performance of main channel is up to standard, when the performance of standby passage is not up to standard, then or by upper After stating channel layer performance and operation layer performance that two passages are detected in step S303, determine that the performance of main channel is not up to standard, When the performance of standby passage is not also up to standard, specific handoff procedure may refer to the above, and overlaps will not be repeated.
It should be noted that can mutually be changed between each state, for example, state 1 can switch to state 2, So state 2 can also switch to state 1, and similarly, state 1 can switch to state 3, and state 3 can also switch to state 1；But no matter How to be changed between each state, when the activestandby state in main channel and standby passage switches over, if the performance of main channel is not bad Change, then business can be transmitted on main channel all the time；If the performance of main channel deteriorates, it is necessary first to determine standby passage Performance whether also deteriorate, if not having, then business can be transmitted and switched on standby passage, if deterioration, then maintain Current state, waits the recovery of main channel or standby passage, so that the communication recovery between master-slave equipment.
