Embodiment
The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
The RPR loop network structure that RPR transannular of the present invention guard method is suitable for is: RPR ring and the 2nd RPR ring interconnect by two websites separately; form two transannular service paths; described RPR encircles two websites, can be any two websites on this RPR ring as required.It is main with website and backup site that two websites that are connected with other RPR rings on each RPR ring are respectively, and these two websites are formed the protection group of this RPR ring; The main of the one RPR ring is called primary link with website and the main of the 2nd RPR ring with the link between the website, and the link between the backup site that backup site that a RPR is encircled and the 2nd RPR encircle claims standby link; Carry out the forwarding of transannular business at synchronization by primary link, when primary link failure, carry out the forwarding of transannular business by standby link, the protection that so forms the professional main/slave link of transannular is switched, and has guaranteed transannular forwarding service security.
Typical R PR loop network structure of the present invention comprises two RPR rings as shown in Figure 2, is respectively RPR ring 1 and RPR ring 2, and both link to each other with website 26 by website 12, website 13, website 25, and then these four websites can be called the transannular website.Website 12 and website 26 by Gigabit Ethernet mouth direct physical link to each other, website 13 links to each other by GE mouth direct physical with website 25; Because the employing of the information interaction between the transannular website on two different RPR rings is 802.3 agreements, therefore, from the second layer of TCP/IP, connects by logic port 802.3MAC port between above-mentioned two transannular websites.
Being divided into two websites in the above-mentioned protection group main preferably, is that two websites are provided with different priority with website and backup site, is that high website is made as and mainly uses website with priority, is that low website is made as backup site with priority.The priority that it is pointed out that reciprocity website is identical, then main reciprocity website with website can be called main reciprocity website, its priority is high, with the main primary link that is made as the transannular business with the link between website and the reciprocity website of master; The reciprocity website of backup site is called is equipped with reciprocity website, its priority is low, and backup site and the link that is equipped with between the reciprocity website are made as standby link.As shown in Figure 2, the priority that the website 12 on the RPR ring 1 is set is low for priority high, website 13, and is corresponding, and the priority of website 26 is low for priority high, website 25 on the RPR ring 2; Link between website 12 and the website 26 is that the link between primary link, website 13 and the website 26 is a standby link.
Among the present invention, when active and standby link all just often, be arranged on synchronization is carried out the transannular business by primary link forwarding, when primary link failure, break down or main link when undesired with website with website and main reciprocity website as main, can enable standby link, guarantee the normal forwarding of transannular business with this.Wherein, switching of primary link and standby link need be according to main state exchange with website and backup site, and the state that the present invention will lead with website is divided into four kinds, is respectively: SELFDOWN: initial isolated state; STANDBY: standby condition; MATEDOWN: the pairing website is forbidden this website initiate mode; ACTIVE: normal this website initiate mode of protection group, this state are main peculiar with website, will illustrate by specific embodiment herein; The state of backup site is divided into three kinds: SELFDOWN, STANDBY and MATEDOWN.The master need just can carry out the conversion of state according to certain condition with website and backup site, will illustrate by specific embodiment herein.
The flow process of RPR transannular of the present invention guard method comprises as shown in Figure 3:
Need to prove that step 301 and step 302 can be carried out simultaneously.
Be example with the master with website below, specify the flow process of RPR transannular of the present invention guard method, as shown in Figure 4, comprising:
Main linking status with website detection and main reciprocity website has dual mode:
The one, detect the physical state of self 802.3MAC port, as link up, link down.Can be provided with, one lasting period, as 300ms in, if the physical state of self 802.3MAC port is link up always, then judge main normal with linking of the reciprocity website of master with website; If in this duration the physical state of 802.3MAC port be always for link down or this section in the period state of link down and link up alternately occur, it is main undesired with linking of the reciprocity website of master with website then to judge;
The one, the master sends and receives a kind of newly-built Ethernet explore frame PeerCC frame mutually with website and main reciprocity website, and whether detect its link normal.As required, Peer CC frame can be set accept to be spaced apart 150ms, when receiving continuously that with website Peer CC frame that main reciprocity website sends reaches default number of times, as 3 times, judge main normal with linking of the reciprocity website of master with website when main; When not receiving Peer CC frame in the main frame time of reception interval of presetting with website, it is main undesired with linking of the reciprocity website of master with website to judge.Wherein, Peer CC frame is to adopt similar Spanning-Tree Protocol (STP, Spanning Tree Protocol) control frame of form, this control frame can both be from this port by arriving the destination when the state of data transfer port is Forward or Block, therefore the master by sending and receiving this Peer CC frame, under any circumstance can both detect the linking status with main reciprocity website with website.
When the master is undesired with linking of website and main reciprocity website, illustrate that the master can't carry out information interaction with main reciprocity website with website, the primary link that is the transannular business is undesired, at this moment, the master enters the SELFDOWN state with website, and return execution in step 401, continue to detect itself and the linking status of leading reciprocity website.
The malunion of clear current transannular website of SELFDOWN state table and reciprocity website often, is promptly born the link of transannular business and temporarily can't be enabled, and then this website can't carry out the forwarding of transannular business.
Use website and lead linking just often of reciprocity website when leading, enter the STANDBY state, execution in step 404 then.
Step 404 judges whether backup site can transmit the transannular business, if not, and execution in step 405; If, execution in step 406.
Whether the master detects backup site with website can transmit the transannular business, be specially: main send the RPR explore frame Mate CC frame of 802.17 agreements mutually with website and backup site, the topological frame in the frame structure and 802.17 of this Mate CC frame, the frame structure of Attribute Discovery frame are consistent; Mate CC frame can be set as required receive and to be spaced apart 150ms, when main when receiving continuously that with website Mate CC frame from backup site reaches default number of times,, judge that then backup site can transmit the transannular business, execution in step 406 as 3 times; Do not receive Mate CC frame with website when main in frame receives at interval, the judgement backup site can not be transmitted the transannular business, execution in step 405, and can think that the state of backup site is SELFDOWN this moment.
Wherein, when main when in default frame receives the interval, not receiving MateCC frame from backup site, show that backup site is unavailable, be that the standby link of transannular business is undesired that then backup site can not be carried out the forwarding of transannular business with website; When receiving continuously that with website Mate CC frame from backup site reaches default number of times, show that standby link is normal when main, backup site can be transmitted the transannular business, can carry out switching of the professional active and standby link of transannular at any time.
When main with website in this state following time, show that the primary link of transannular business is normal, carry out the forwarding of transannular business by main with website, but standby link is undesired, can not carry out switching of main/slave link at any time.This moment is main to continue to detect self and the linking status of main reciprocity website with website, and continues to detect backup site and whether can transmit the transannular business, can carry out the forwarding of transannular business in case detect backup site, and then execution in step 406.
When backup site can be transmitted the transannular business, the master entered the ACTIVE state with website.Main with website in this state following time, show that the primary link of transannular business and standby link all are normal, carry out the forwarding of transannular business by primary link this moment, and can carry out switching of main/slave link at any time.
Which kind of state embodiment by Fig. 4 mainly is in website and needs the linking status with main reciprocity website is detected, promptly primary link detected as can be seen; When the master is in STANDBY, MATEDOWN and ACTIVE state with website, sends and receive Mate CC frame, judge whether backup site can transmit the transannular business to backup site; And only when the SELFDOWN state, do not send or receive Mate CC frame to backup site, in this case, backup site does not receive the Mate CC frame of independently using website in default frame receives at interval, then backup site thinks that the master can not transmit the transannular business with website, and this moment, backup site began to carry out the forwarding of transannular business; When backup site receives main Mate CC frame with website when reaching default number of times again continuously, show and mainly can transmit the transannular business that the forwarding of transannular business at this moment is switched to primary link by standby link again with website.
Be example with standby website below, specify the flow process of RPR transannular of the present invention guard method, as shown in Figure 5, comprising:
The mode that the operation of this step is adopted repeats no more with step 401 herein.
When backup site be equipped with linking of reciprocity website when undesired, illustrate backup site can't be equipped with reciprocity website and carry out information interaction, be that the standby link of transannular business is undesired, at this moment, backup site enters the SELFDOWN state, and return execution in step 501, continue to detect itself and the linking status that is equipped with reciprocity website.
It is pointed out that backup site does not send or receive Mate CC frame to main with website under this state.
When backup site be equipped with linking just often of reciprocity website, enter the STANDBY state, execution in step 504 then.
Step 504 judges whether the master can transmit the transannular business with website, if not, and execution in step 505; If return step 503.
Backup site judges whether the master can transmit the transannular business with website, and concrete detection mode repeats no more with step 404 herein.
When the master can not transmit the transannular business with website, think that main state with website is SELFDOWN, execution in step 505; If the master can carry out the forwarding of transannular business with website, then backup site will continue to remain on the STANDBY state.
When the master can not transmit the transannular business with website, think that main state with website is SELFDOWN, this moment, backup site began to carry out the forwarding of transannular business, and detect constantly and the linking status that is equipped with reciprocity website, and detect the master constantly and whether can transmit the transannular business with website, can transmit the transannular business in case backup site detects the master with website, carry out switching of main/slave link at once.
By the embodiment of Fig. 5 as can be seen, when backup site is in SELFDOWN, STANDBY and MATEDOWN state, needs to detect with the linking status that is equipped with reciprocity website, promptly standby link detected; When backup site is in STANDBY and MATEDOWN state, sends and receive Mate CC frame, judge whether the master can transmit the transannular business with website with website to main; And only when the SELFDOWN state, do not send or receive Mate CC frame with website to main, in this case, the master does not receive the Mate CC frame of independently using website with website, then mainly think that with website backup site can not carry out the forwarding of transannular business, be that standby link is undesired, this moment is main to enter the MATEDOWN state with website; When main when receiving the Mate CC frame of backup site again with website, show that backup site can have been transmitted the transannular business, to be that standby link recovers normal, this moment is main to enter the ACTIVE state with website, begins to transmit the transannular business.
Embodiment by Fig. 4 and Fig. 5 as can be seen, the ACTIVE state is main distinctive with website because primary link and standby link all are normal under this state, this state indication this moment is born the forwarding of transannular business by primary link, standby link is the STANDBY state; If primary link failure is born the forwarding of transannular business by standby link, for backup site, the state of this moment is that pairing website forbidding, this website are enabled corresponding MATEDOWN state; When primary link failure recovers; bear the forwarding of transannular business again by primary link; the state of this moment be the protection group normally, promptly main all normal with website and backup site, corresponding main ACTIVE state, and backup site is got back to the STANDBY state by the MATEDOWN state with website.
In order to realize said method, the present invention also provides a kind of RPR transannular protection system, and this system is based on RPR ring, and as shown in Figure 6, this system comprises: main with website 10, backup site 20, lead reciprocity website 30 and be equipped with reciprocity website 40, wherein:
The main website 10 of using links to each other with backup site 20; The main website 10 of using links to each other with main reciprocity website 30; Backup site 20 be equipped with reciprocity website 40 and link to each other; Main reciprocity website 30 be equipped with reciprocity website 40 and link to each other;
