Embodiment two
Whether direct-connected embodiments provide and a kind ofly to detect between router method, in conjunction with the content of above-described embodiment one, as shown in Figure 3, the method that the present embodiment provides comprises:
301: transmitting terminal router sends to receiving terminal router and detects code stream.
Wherein, receiving terminal router and transmitting terminal router are the routers that can be found by the webmaster of IPRAN network, are two known routers.Whether the detection code stream that transmitting terminal router sends to receiving terminal router is direct-connected for detecting the two, this detection code stream includes but not limited to distinguish over existing agreement code stream based on detection identifier, it can be a kind of self-defining code stream, also can realize based on the reservation position of existing agreement code stream, the present embodiment does not limit error detecting code stream.Preferably, in the present embodiment, detect code stream to realize based on the reservation position in electric mouth auto-negotiation information coding or light mouth auto-negotiation information coding, that is, the frame format detecting code stream obtains by modifying to the frame format of electric mouth auto-negotiation information coding or light mouth auto-negotiation information coding, and the reservation position of the corresponding electric mouth auto-negotiation information coding of the detection identifier detecting code stream or light mouth auto-negotiation information coding.
Table 1 is electric mouth auto-negotiation information coding base page frame structure, and wherein, A7 position is for retaining position; Table 2 is electric mouth auto-negotiation information coding additional page frame structures, and wherein, U5 ~ U10 position is for retaining position.When transmitting terminal router is connected by network with receiving terminal router, detecting code stream can realize based on the reservation position of electric mouth auto-negotiation information coding, and it can utilize one or multidigit realization in above-mentioned A7, U5 ~ U10.Such as, can it is defaulted as 0 by above-mentioned A7 position is set to 1() be used as the detection identifier detecting code stream, also can by U5, U6 and U7 tri-being all set to the detection identifier that 1 is used as detecting code stream.
For simplicity, the present embodiment is only described using A7 position as the situation of the detection identifier detecting code stream.When the frame head of the code stream that receiving terminal router receives is identical with the frame head of the code stream of electric mouth auto-negotiation information coding, it extracts the first numerical value from the first precalculated position of A7 position correspondence, first numerical value may be 1 or 0, represent that when the first numerical value is 1 the code stream received detects code stream, when the first numerical value is 0, represent that the code stream received is the code stream of common electric mouth auto-negotiation information coding.
Table 1
| S0 | S1 | S2 | S3 | S4 | A0 | A1 | A2 | A3 | A4 | A5 | A6 | A7 | RF | ACK | NP |
Table 2
| U0 | U1 | U2 | U3 | U4 | U5 | U6 | U7 | U8 | U9 | U10 | T | Ack2 | MP | Ack | NP |
For light mouth auto-negotiation information coding, in its frame structure 0 ~ 4, and 9 ~ 11 are reservation position, be similar to the frame format obtaining detecting code stream above by modifying to the frame format of electric mouth auto-negotiation information coding, when transmitting terminal router and receiving terminal router are by Fiber connection, can obtain by modifying to light mouth auto-negotiation information coding frame structure detecting the frame format of code stream, namely choosing in electric mouth auto-negotiation information coding that one or more retains position as the detection identifier detecting code stream.Its implementation is similar with the situation of modifying to the frame format of electric mouth auto-negotiation information coding, repeats no more herein.
In addition, transmitting terminal router and receiving terminal router, all through pre-configured, can send and recognition detection code stream, specifically can carry out pre-configured to transmitting terminal router and receiving terminal router by order line.Meanwhile, testing staff can trigger transmitting terminal router by order line and send detection code stream to receiving terminal router.
302: receiving terminal router receiving end/sending end router transmitted stream.
For this step, the present embodiment does not limit the mode of receiving terminal router receiving end/sending end router transmitted stream, because receiving terminal router is connected by network with transmitting terminal router, therefore, receiving terminal router is by network reception transmitting terminal router transmitted stream.In addition, whether direct-connected transmitting terminal router transmitted stream can for for detecting detection code stream, and also can be existing agreement code stream, the present embodiment limit the type of the transmitting terminal router transmitted stream that receiving terminal router receives.
303: receiving terminal router judges whether the code stream received is detect code stream, if so, performs step 304.
Wherein, whether direct-connected transmitting terminal router transmitted stream except can for for detecting except detection code stream, can also be existing agreement code stream.If have the 3rd network element device between receiving terminal router and transmitting terminal router, and transmitting terminal router transmitted stream is for detecting code stream, then because the 3rd network element device is the network element device that can not be found by the webmaster of IPRAN network, such as switch, microwave equipment, wave-division device, and the router etc. in double layer network, 3rd network element device detects code stream due to None-identified, thus after the detection code stream that transmitting terminal router sends is sent to the 3rd network element device, 3rd network element device will abandon it, receiving terminal router also just cannot receive the detection code stream that transmitting terminal router sends.But if there is between receiving terminal router and transmitting terminal router the 3rd network element device, and transmitting terminal router transmitted stream is existing agreement code stream, then the 3rd network element device can identify it, and is transmitted to receiving terminal router.And for example there is no the 3rd network element device between fruit receiving terminal router and transmitting terminal router, namely receiving terminal router and transmitting terminal router are direct-connected, then no matter transmitting terminal router sends is detected code stream or sends existing agreement code stream, and receiving terminal router can receive and obtain.
To sum up, receiving terminal router is after receiving transmitting terminal router transmitted stream, directly can not determine that the code stream that it receives detects code stream or other agreement code streams, therefore, whether at the needs receiving the transmission of transmitting terminal router, receiving terminal router judges whether this code stream is detect code stream, thus determine with transmitting terminal router direct-connected according to judged result.
Judge whether the code stream received is the mode detecting code stream, and the present embodiment does not do concrete restriction, specifically includes but not limited to: receiving terminal router extracts the first numerical value from the first precalculated position of the code stream received about receiving terminal router; The detection identifier of the first numerical value with the detection code stream prestored is compared, judges whether the code stream received is detect code stream according to comparing result.Wherein, the present embodiment does not limit the particular location of the first precalculated position in code stream.
Further, if the code stream received detects code stream, the frame format of this detection code stream obtains by modifying to the frame format of auto-negotiation information coding, and the reservation position of the corresponding auto-negotiation information coding of the detection identifier detecting code stream.Therefore, this first precalculated position can correspond to the reservation position of auto-negotiation information coding, receiving terminal router is by extracting the numerical value of the reservation position corresponding to auto-negotiation information coding in the code stream that receives, after it can be used as the first numerical value extracted, by itself and the detection identifier of detection code stream prestored are compared, if consistent, then determine that the code stream received is for detecting code stream.
Certainly, whether the code stream received except above-mentioned judgement is detect except the mode of code stream, and can also take other judgment modes, the present embodiment does not do concrete restriction to this.
Preferably, consider that the form of other custom protocols may be identical or similar with the form of described detection code stream, such as, other custom protocols also choose electric mouth auto-negotiation coding base page in A7 position as its identifier, in order to avoid the code stream of other custom protocols is mistakenly identified as described detection code stream by receiving terminal router, transmitting terminal router also sends detection validation password to receiving terminal router, receiving terminal router is apprised of detection validation password in advance, the second value that receiving terminal router extracts from second precalculated position (position of corresponding detection validation password) of the code stream received and detection validation password are to contrast, if identical, then judge whether the code stream received exists detection identifier further, if second value is different from detection validation password, even if the code stream received exists detect identifier, code stream neither be detected, therefore also just without the need to judging whether the code stream received exists detection identifier again.By above-mentioned design, receiving terminal router recognition detection code stream by mistake can be avoided, thus can improve the accuracy of testing result further, improve the accuracy of IPRAN fault location.Further, in order to more effectively avoid situation about identifying by mistake, detection validation password is generally multidigit, and it can be kept in the reservation position of the register of receiving terminal router, and can be kept in newly-increased register, the present embodiment does not do concrete restriction to this yet.
304: receiving terminal router is determined with transmitting terminal router direct-connected, send to transmitting terminal router and detect response code stream corresponding to code stream.
For this step, detect code stream and whether be direct-connectedly used for determining between two routers, thus when receiving terminal router determines that the transmitting terminal router transmitted stream that receives is for after detecting code stream, can determine with transmitting terminal router direct-connected.Further, direct-connected in order to make transmitting terminal router also can determine with receiving terminal router, the method that the present embodiment provides receiving terminal router determine direct-connected with transmitting terminal router after, also comprise and send to transmitting terminal router the process detecting response code stream corresponding to code stream.
Wherein, the general form with detecting code stream of response code stream is corresponding, and can be sent out and hold router to identify.Therefore, when detecting code stream using the reservation position in auto-negotiation information coding as detection identifier, one or more reservation positions responsively identifier that response code stream can take with identifier not detected in auto-negotiation information coding, such as when detecting code stream using the A7 position in electric mouth auto-negotiation coding base page as detection identifier, response code stream can with the U5 position responsively identifier in electric mouth auto-negotiation coding additional page, also can based on the responsively identifier jointly of the U5 ~ U7 in electric mouth auto-negotiation coding additional page.
Similar, when detecting code stream using the one or more reservation positions in light mouth auto-negotiation information coding as detection identifier, one or more reservation positions responsively identifier that response code stream can take based on identifier not detected in light mouth auto-negotiation information coding, about the form of response code stream, the present embodiment does not do concrete restriction.
305: transmitting terminal router judges whether the response code stream receiving the correspondence detection code stream that receiving terminal router returns, and if so, performs step 306, if not, performs step 307.
For this step, because receiving terminal router is at the detection code stream receiving transmitting terminal transmission, and judge that it is detect after code stream, receiving terminal router can return the corresponding response code stream detecting code stream to transmitting terminal router, therefore, transmitting terminal router is receiving receiving terminal router transmitted stream, and judges that whether direct-connected this code stream is as after response code stream, can judge with receiving terminal router.Judge whether the mode of the response code stream receiving the correspondence detection code stream that receiving terminal router returns about transmitting terminal router, the present embodiment does not do concrete restriction.During concrete enforcement, judge that whether the code stream that receives is that to detect the principle of code stream identical with receiving terminal router.Such as, transmitting terminal router, can by extracting the numerical value in the precalculated position of the code stream that receive after receiving the code stream that receiving terminal router returns, and compared by its identifier with the response code stream prestored, if consistent, then determine that the code stream received is response code stream.
Certainly, transmitting terminal router receives except the response code stream of the correspondence detection code stream that receiving terminal router returns except judging whether by the way, and can also adopt other judgment modes, the present embodiment does not do concrete restriction to this.
306: transmitting terminal router is determined with receiving terminal router direct-connected, and flow process terminates.
For this step, detect code stream because response code stream corresponds to, and whether detect code stream direct-connected for detecting, because transmitting terminal router judges to receive the response code stream that receiving terminal router returns, therefore, transmitting terminal router is determined with receiving terminal router direct-connected.
307: transmitting terminal router is determined to be provided with the 3rd network element device between receiving terminal router, and flow process terminates.
For this step, code stream is detected because response code stream corresponds to, and whether detect code stream direct-connected for detecting, therefore, if the judgement of transmitting terminal router does not receive the response code stream that receiving terminal router returns, then transmitting terminal router is determined to be provided with the 3rd network element device between receiving terminal router, and its detection code stream sent to receiving terminal router is abandoned by the 3rd network element device.
The method that the present embodiment provides, code stream is detected by sending between two known routers, and whether receive detection code stream according to receiving terminal router, whether the mode whether transmitting terminal router receives response code stream judges between two routers direct-connected, thus to improve between detection two routers the accuracy of whether direct-connected method, and then the accuracy of IPRAN fault location can be improved.

Embodiments provide a kind of receiving terminal router, as shown in Figure 4, this receiving terminal router comprises its structure:
Receiver module 41, for receiving end/sending end router transmitted stream;
