Description
Technical field
The present invention relates to communication technical field, particularly a kind of collocation method of APS mode of operation and equipment.
Background technology
APS (Auto Protocol Switch, automatic protection switching) is a kind of automatic protection switching mechanism of SDH (Synchronous DigitalHierarchy, synchronous digital signal framework) link.
The principle that realizes of APS is exactly the switch protecting using redundant link to carry out transfer of data.In the system of application APS technology; the link composition of chain route two type between two communication equipments; comprise active link and protection link; when active link goes wrong; transfer of data between two communication equipments is switched to protection link and proceeds work, thus ensures normally carrying out of transfer of data.
In actual applications, the realization of APS technology comprises 1+1 and 1:n two kinds of backup modes.
1+1 pattern is exactly that the communication equipment of transmitting terminal all sends data on two links (active link and protection link), and the communication equipment data specifically received on which bar link of receiving terminal depend on the configuration of the communication equipment self of receiving terminal.
1:n pattern is protected many active links by a protection link; protection link is in idle condition usually; only when certain active link goes wrong; just the data exchange that this active link gone wrong transmits is sent to protection link; in concrete application scenarios; also have the backup mode of a kind of 1:1, this pattern then can think a kind of special case of 1:n pattern, is namely protected an active link by a protection link.
When APS switches, two-way switching and unidirectional handover two kinds of switch modes can also be divided into.
If two-way switching; before and after then switching; all the time same link (active link or protection link) to be used to carry out data transmit-receive by the communication equipment at link-attached two ends; as shown in Figure 1; for applying the schematic diagram of the application scenarios of the two-way switching of APS in prior art; in this scenario; before switching; active link is used to carry out data transmit-receive between communication equipment A and communication equipment B; and after handover; data transmit-receive between communication equipment A and communication equipment B all switches and all switches, and uses protection link to carry out data transmit-receive.
And for the switch mode of unidirectional handover, before and after then switching, different link (active link or protection link) can be used to carry out data transmit-receive by the communication equipment at link-attached two ends, as shown in Figure 2, for applying the schematic diagram of the application scenarios of APS unidirectional handover in prior art, in this scenario, before switching, active link is used to carry out data transmit-receive between communication equipment A and communication equipment B, and after handover, the link that communication equipment A sends data to communication equipment B switches, be switched in protection link, communication equipment B sends the link of data to communication equipment A and then remains on active link and do not switch, therefore, for two communication equipments, the link at its data transmit-receive place has been come by different links after handover.
APS handoff protocol controls to switch by K1, K2 byte in SDH frame format head.K1 byte can identify the type of request switching and need the link number of switching (active link identifies by numbering with protection link); K2 byte then identifies the link number switched, and the operating mode information that the communication equipment of local terminal configures: comprising backup mode is 1+1 or 1:n (comprising 1:1), and switch mode is application unidirectional handover or applies two-way switching.
In existing technical scheme, for the application scenarios of application APS handoff protocol, the communication equipment that both link ends connects, its APS mode of operation (backup mode of APS is 1+1 or 1:n, and switch mode is application unidirectional handover or applies two-way switching) is all that user carries out manual configuration on the communication equipment at two ends.

In the application scenarios of reality, consider the compatibility with the technology of existing manual configuration APS mode of operation, in technical scheme proposed by the invention simultaneously compatible manual configuration with automatically configure two kinds of configuration modes, concrete implementation is the setting being configured mode in a communications device, communication equipment needs at it identification being configured mode during configuration or the renewal carrying out APS mode of operation, if recognition result is auto configuration mode, the APS mode of operation configuration of self is then carried out according to opposite end APS mode of operation, if recognition result is manual configuration, then continue to use the configuration that existing manual configuration mode carries out APS mode of operation.By such technical scheme, can be implemented in communication equipment carries out APS mode of operation flexibly configuration by auto configuration mode or manual configuration mode, increase the flexibility of corresponding hardware configuration deployment strategy.
In concrete application scenarios, the way of realization of above-mentioned configuration mode can be realized by instruction mode, specifically as shown in table 1.
The instruction of table 1 configuration mode
| Command forms | Order implication |
| Mode-Gen peer-Match | The APS mode of operation of the communication equipment of coupling opposite end |
| Mode-Gen Local-Config | The APS mode of operation configuration of coupling local terminal |
In concrete enforcement scene, if the content recognized is " Mode-Gen peer-Match ", then determine that the configuration mode of the APS mode of operation of self is that the APS mode of operation of the communication equipment of adaptive opposite end carries out adaptation, if the content recognized is " Mode-Gen Local-Config ", then determine that the configuration mode of the APS mode of operation of self is the configuration that the configuration information directly applying local terminal carries out APS mode of operation, the similar and manual configuration process flow process of the prior art of concrete workflow.
In the application of reality; above-mentioned instruction type and setting means can adjust according to actual needs; and the processing mode that can reach configuration mode setting equally can be applied to the technical program equally, and such change does not affect protection scope of the present invention.
The content of the K2 byte in the SDH frame received by step S503, communication equipment obtain.
In concrete application scenarios, the whether effective basis for estimation of APS operating mode information for opposite end in technical scheme proposed by the invention can set for the byte in SDH frame format head in conjunction with in APS handoff protocol, is set by the content of information entrained in SDH frame.
Such as, can by the content in the K2 byte of SDH frame as basis for estimation, in existing APS handoff protocol, the implication representated by the content in the bit6 ~ bit8 of K2 byte is as shown in table 2:
Table 2 K2 [6:8] Operation Mode or Non-APS Use
(mode of operation state representated by the bit6 ~ bit8 of K2 byte or non-APS purposes)
| Bit contents | Representative state content |
| 111 | Line AIS (Line Alarm Indication Signal, alarm indication signal link) |
| 110 | Line RDI (Line Remote Defect Indication, remote bug instruction link) |
| 101 | Bidirectional Mode (two-way switch mode) |
| 100 | Unidirectional Mode (unidirectional handover pattern) |
| Other | Reserved for future use (being that other following purposes are reserved) |
Consider in above-mentioned every content, other guide all illustrates the state content of non-APS, and only have 101 and 100 to illustrate switch mode in APS mode of operation, also only have the APS mode of operation just representing opposite end at this moment in running order, therefore, if need to carry out APS mode of operation to the communication equipment of local terminal to be configured, so, in order to ensure that the APS mode of operation after configuring can normally work, need by the APS mode of operation of local terminal and the APS mode of operation of opposite end suitable, namely the APS mode of operation configured according to the communication equipment of opposite end carries out the APS mode of operation configuration of local terminal.
Based on above-mentioned analysis, pre-conditionedly can be set as aforesaid: the content in the bit6 ~ bit8 of the K2 byte of the SDH frame received is 101 or 100, to be i.e. in the bit6 ~ bit8 of K2 byte, to carry the switch mode configuration information of the communication equipment of opposite end.Only when meeting this and being pre-conditioned, just determine that the APS mode of operation of the communication equipment of opposite end starts, this APS operating mode information entrained by SDH frame is effective, otherwise, judge that the APS mode of operation of the communication equipment of opposite end is not activated, this APS operating mode information entrained by SDH frame is invalid.
Based on above-mentioned analysis, after getting the content of K2 byte of SDH frame, perform step S504 further.
Step S504, communication equipment judge that whether Bit6 ~ the Bit8 of K2 byte is effective.
If effectively, namely the content of Bit6 ~ Bit8 is 101 or 100, then perform step S505;
If invalid, namely the content of Bit6 ~ Bit8 is the other guide beyond 101 or 100, then perform step S506.
The APS operating mode information that the communication equipment that step S505, communication equipment obtain opposite end from SDH frame configures, and the APS mode of operation configuring self according to APS operating mode information.
As stated in the Background Art, APS mode of operation mainly comprises switch mode and backup mode, therefore, if the switch mode of the communication equipment of opposite end and the configuration information of backup mode can be obtained, then local communication equipment just can carry out the configuration of local APS mode of operation according to such configuration information, so, in the application process of reality, the processing procedure of the APS operating mode information that the communication equipment obtaining opposite end in SDH frame in this step configures is specially the process of the switch mode of the communication equipment obtaining opposite end in SDH frame respectively and the configuration information of backup mode.
Further combined with aforesaid application scenarios, when the content judging in the bit6 ~ bit8 of K2 byte is in step s 302 101 or 100, communication equipment confirms that the APS operating mode information entrained by SDH frame is effective, therefore, obtain the content in the bit6 ~ bit8 of K2 byte as the communication equipment of opposite end switch mode configuration information (as previously mentioned, 101 is two-way switch mode, 100 is unidirectional handover pattern), and obtain the backup mode configuration information of the content in the bit5 of K2 byte as the communication equipment of opposite end further (in the application of reality, the backup mode of 1+1 can be represented with 0, the backup mode of 1 expression 1:n), after the switch mode configuration information of communication equipment completing opposite end and the acquisition of backup mode configuration information, this communication equipment just can complete the configuration of the APS mode of operation of self according to these configuration informations.
Step S506, communication equipment use the APS mode of operation of the APS mode of operation configuration self of local terminal.
If the judged result in step S502 is no, then represent that this communication equipment still continues to use prior art, directly carry out the configuration of the APS mode of operation of this communication equipment according to the APS work mode configuration information of local terminal.
If and the judged result in step S504 is invalid, then represent that the APS mode of operation in the communication equipment of opposite end is not activated, or the APS operating mode information that cannot get in the communication equipment of opposite end accurately, therefore, the configuration of the APS mode of operation of self can not be carried out according to the APS operating mode information of the communication equipment of opposite end, in concrete application scenarios, on the one hand, the APS mode of operation of the APS mode of operation configuration self of the use local terminal proposed in this step can be applied, on the other hand, processing policy in such cases can also be pre-configured in, such as:
(1) default configuration
Be configured according to acquiescence APS mode of operation collocation strategy, such acquiescence APS mode of operation collocation strategy can pre-set in a communications device, also can be a kind of default configuration being applicable to all communication equipments, everyly all will directly apply this default configuration when not configuring concrete ASP operating mode information, thus, ensure that communication equipment can configure APS mode of operation, and carry out follow-up start treatment, the content of concrete acquiescence APS mode of operation collocation strategy can adjust according to the needs of embody rule scene, such change does not affect protection scope of the present invention.
(2) manual configuration
Namely the mode of carrying out configuration automatically according to the APS operating mode information of the communication equipment of opposite end is abandoned; and again continue to use existing manual configuration scheme; the APS operating mode information of manual configuration can be configured to (i.e. the APS mode of operation of the APS mode of operation configuration self of aforesaid use local terminal) in communication equipment in advance; also can when the judged result of step S504 be invalid; prompting or alarm is sent by communication equipment; manual configuration is carried out in prompting, and such change does not affect protection scope of the present invention.
(3) configuration is abandoned
Namely when the judged result of step S504 is invalid, directly abandon the configuration this communication equipment being carried out to APS mode of operation, this kind of strategy can be applied in the system environments allowing not apply APS, and, if abandon configuration, whether send prompting to user or network manager, can be configured according to actual needs.
In the application scenarios of reality, except above-mentioned three kinds of subsequent treatment strategies, can also determine the processing policy of other types according to actual needs, which kind of subsequent treatment strategy of embody rule, can't affect protection scope of the present invention.
By the processing procedure of above-mentioned steps S505 or step S506, communication equipment completes the configuration of the APS mode of operation of self, then, performs step S507.
Step S507, communication equipment normally start APS process, realize corresponding transfer of data to the communication equipment of opposite end.
It is further noted that, starting APS process and carrying out in the process of normal transfer of data, if the communication equipment of opposite end needs adjustment APS mode of operation, the APS that the communication equipment that communication equipment can receive opposite end sends interrupts Indication message, notify that this communication equipment carries out the config update of APS mode of operation, corresponding renewal process and aforesaid layoutprocedure similar, its schematic flow sheet as shown in Figure 6, specifically comprises the following steps:
Step S601, communication equipment receive APS and interrupt Indication message.
Step S602, communication equipment determine whether the APS mode of operation configuration carrying out self according to opposite end APS mode of operation.
If judged result is yes, perform step S603;
If judged result is no, perform step S608.
APS received by step S603, communication equipment obtain interrupts the content of the K2 byte in Indication message.
In concrete enforcement scene, the effect that APS interrupts Indication message can be specially the change notifying K2 byte, so the K2 change information that this step is directly interrupted in Indication message according to APS carries out follow-up basis for estimation.
Step S604, communication equipment judge that whether Bit6 ~ the Bit8 of K2 byte is effective.
Concrete judgment rule arranges the explanation with reference to aforesaid step S503 to step S504, at this no longer repeated description.
If effectively, namely the content of Bit6 ~ Bit8 is 101 or 100, then perform step S605;
If invalid, namely the content of Bit6 ~ Bit8 is the other guide beyond 101 or 100, then perform step S608.
The information of the APS mode of operation that the communication equipment that step S605, communication equipment interrupt obtaining opposite end Indication message from APS configures.
Concrete acquisition process is with reference to the explanation in aforesaid step S505, and the content obtained comprises the switch mode of the communication equipment of opposite end and the configuration information of backup mode.
Step S606, communication equipment judge that whether self current configured APS mode of operation is consistent with the APS mode of operation that the communication equipment of the opposite end again got configures.
Namely the renewal that there occurs APS operating mode information is determined whether.
If inconsistent, then perform step S607;
If consistent, then perform step S608.
Step S607, communication equipment upgrade the APS mode of operation of self according to the APS operating mode information again got.
After renewal completes, communication equipment restarts APS process, continues to realize corresponding transfer of data to the communication equipment of opposite end.
The APS mode of operation upgrading self abandoned by step S608, communication equipment.
Under the scene performing this step, communication equipment continues to perform current APS process, carries out transfer of data with the communication equipment of opposite end.
