The specific embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
The method of hoop configuration that realizes in loop network provided by the invention comprises: the transmit leg node send comprise self loop to the hoop information of precedence information; When recipient's node is received from the hoop information of transmit leg node, the corresponding priority of precedence information that relatively comprises in self priority and the hoop information of receiving, when the priority of recipient's node was hanged down relatively, recipient's node determined self to comply with the hoop of loop according to the hoop that comprises in the hoop information of receiving; Otherwise, recipient's node according to the hoop collocation strategy that sets in advance determine self loop to.
The system of hoop configuration that realizes in loop network provided by the invention comprises RPR administrative unit and the interface unit that links to each other with the RPR administrative unit, also comprises the hoop negotiation element; Wherein, interface unit is used for carrying out the transmitting-receiving of loop information; The RPR administrative unit is used for safeguarding described interface unit incidence relation and communicating management work; The hoop negotiation element, the hoop information that comprises hoop and precedence information for other communication node of receiving according to interface unit, judge whether self corresponding device has relatively the highest priority, if so, determine the hoop of self corresponding device according to the hoop collocation strategy that sets in advance; Otherwise, determine that according to the hoop that comprises in the hoop information from the relatively the highest communication node of priority self corresponding device complies with the hoop of loop.
After having set up incidence relation between two loop interface that application prior art each communication node on the RPR ring comprises, just can carry out having disposed for the hoop of each communication node. In multiple situation, the communication node on the RPR ring might need to carry out hoop configuration, as: RPR only is provided with on the ring and adds/deleted communication node on a communication node, the RPR ring, two RPR rings are formed a RPR encircles etc. during initial networking. The below uses a plurality of embodiment and respectively the hoop layoutprocedure under the different situations is described.
Embodiment one: RPR only is provided with a communication node during initial networking on the ring.
Referring to Fig. 2, Fig. 2 is the hoop configuration schematic diagram of the embodiment of the invention one. Only comprise node A 210 on the RPR ring among Fig. 2, loop interface 211 is connected with dotted line between the loop interface 212 that to represent between loop interface 211 and the loop interface 212 be inner the connection.
In actual applications, also can further comprise other communication node on the RPR ring, but other communication node except node A 210 all is in (shutdown) state of closing, a communication node communication information that self is received that is in the shutdown state is carried out transparent transmission, and does not carry out other operation.
When carrying out the hoop configuration, node A 210 determines the hoop of self according to the hoop collocation strategy that sets in advance. Described hoop collocation strategy can be to determine hoop according to the loop interface shut sequence of node A 210, as: when related loop interface 211, the loop interface 212, shut sequence is again related loop interface 212 of the related loop interface 211 of elder generation, 210 definite loop interface 211 of node A are that the west is to interface, loop interface 212 is the east orientation interface, that is: node A 210 determine its upper loop interface 211 residing ends be western to, loop interface 212 residing ends are east orientation. Certainly, also first related loop interface can be defined as the west to interface, the loop interface of rear association is defined as the east orientation interface, that is: node A 210 determines that its upper loop interface 211 residing ends are east orientation, loop interface 212 residing ends be western to.
Described hoop collocation strategy also can be random setting, determines at random that such as: node A 210 its upper loop interface 211 residing ends are east orientation, loop interface 212 residing ends be western to.
After node A 210 has finished and self has been arranged circumferentially, sent to end goes out the west to direction from hoop information to the local terminal loop by self west; And by self east orientation end the direction that east orientation hoop information goes out to the local terminal loop is sent. Concrete operations are: by loop interface 211 direction that the west goes out to hoop information to this interface loop is sent; By loop interface 212 east orientation hoop information is sent to the direction that this interface loop goes out.
Described east, west to hoop information except comprising heading of the prior art, also comprise node priority parameter and this hoop information of indication the hoop parameter of corresponding hoop. Described hoop information normally periodically sends. The nodal informations such as address that comprise node A 210 in the described heading.
Described node priority parameter sets in advance in each communication node on the RPR ring usually, described hoop parameter is a numerical value normally, as: the hoop parameter is 0 o'clock, represent described hoop information for the west to hoop information, send this west to an end of the communication node of hoop information for the west to; The hoop parameter is 1 o'clock, and representing described hoop information is east orientation hoop information, and an end that sends the communication node of this east orientation hoop information is east orientation.
Certainly, also can set in advance the master slave mode of communication node, and set and to only have host node could send hoop information, described state setting as; The master slave mode of communication node is set to slave mode, makes the communication node acquiescence certainly as slave node. Arranging of master slave mode can pass through to add the realization of master slave mode parameter in the configuration parameter of communication node, as: the master slave mode parameter value of communication node is 0, and the master slave mode that represents this communication node is slave mode.
Have again, state conversion timing device can be set in communication node, make state conversion timing device when not receiving hoop information, continue timing, and when state conversion timing device is overtime, determined certainly as host node by the communication node at state conversion timing device place; State conversion timing device restarts when receiving hoop information. Described state conversion timing device does not have strict some start-up time, and its any time in communication process all can start.
Described communication node is determined to have from the method as host node multiple, as: the master slave mode parameter value of communication node self is set to 1, and representing this communication node is host node. The duration of described state conversion timing device can be according to the settings such as transmission cycle of described hoop information, as: the duration of state conversion timing device is three times that hoop information sends the cycle.
As seen, if be provided with the master slave mode of communication node, communication node will be given tacit consent to certainly at first as slave node; Communication node is determined certainly as host node when state conversion timing device is overtime. And, communication node application of aforementioned correlation method determine self loop to; After having determined hoop, the application of aforementioned correlation method sends described hoop information.
By the above as can be known, among Fig. 2, if the RPR ring is open loop, then no matter only have node A 210 still further to comprise the communication node that other is in the shutdown state on the RPR ring, node A 210 can not receive the hoop information from self or other node, and node A 210 can determine when state conversion timing device is overtime from as host node and send self hoop information so. Aforesaid operations will circulate down always. If the RPR ring is closed loop, then no matter only have node A 210 still further to comprise the communication node that other is in the shutdown state on the RPR ring, node A 210 can both receive hoop information before state conversion timing device is overtime, and peels off this hoop information when definite this hoop information belongs to self.
Above-mentioned hoop collocation strategy, node priority parameter, master slave mode, state conversion timing device etc. also can be applied among other the embodiment. And the node priority parameter of each communication node and hoop can arrange when the initial configuration communication node on the RPR ring, and the respective rings of describing in can Application Example one when described hoop is set is to collocation method.
In actual applications, if newly added a communication node on the RPR ring shown in Figure 2, the visible embodiment two of hoop layoutprocedure so afterwards.
Embodiment two: added communication node on the RPR ring.
Referring to Fig. 3, Fig. 3 is the hoop configuration schematic diagram of the embodiment of the invention two. Comprise node 310, node 320 on the RPR ring among Fig. 3. Wherein, node 310 is originally just to be arranged on the RPR ring, and 320 of nodes are newly to add the RPR ring. Under normal circumstances, node 310 should be determined certainly as host node, and send the hoop information of self; Node 320 is given tacit consent to certainly as slave node when the new RPR of adding ring.
When node 320 is received hoop information from node 310, the priority that the hoop information that node 320 is relatively received comprises and the priority of self, if the priority of node 320 is relatively high, node 320 is determined to send the hoop information of self from the hoop of also determining self as host node according to the hoop collocation strategy that sets in advance again; If the priority of node 320 is relatively low, the hoop information that 320 bases of node are received determines self to comply with the hoop of loop, and the described hoop information that will receive continues to send.
Describedly determine that the hoop of complying with loop refers to: receive the communication node from other communication node hoop information, determine self to receive the hoop of this hoop information one end, and the definite hoop of assurance can be supported other communication node proper communication on this communication node and the RPR ring. Such as: if an end of node 320 is received west from node 310 to hoop information, 320 of nodes are determined self to receive that described west is east orientation to an end of hoop information; Equally, if an end of node 320 is received the east orientation hoop information from node 310, the end that 320 of nodes determine self to receive described east orientation hoop information for the west to.
Particularly, above-mentioned compare operation comprises: the node priority parameter that the hoop information that node 320 is relatively received comprises and the node priority parameter that self arranges, if the node priority parameter value of node 320 is relatively large, node 320 determines that the priority of self is relatively high; If the node priority parameter value less of node 320, node 320 determines that the priority of self is relatively low; If the node priority parameter value that described hoop information comprises is identical with the node priority parameter value of node 320, the node address that the more described hoop information of 320 continuation of node comprises and the node address of self, if the address value of node 320 is relatively large, node 320 determines that the priority of self is relatively high; Otherwise 320 priority of determining self of node are relatively low.
When node 320 determines that self priority is relatively low, described node 320 determines that self loops comprise to the method for information: the hoop information read loop that node 320 is received from the loop interface that is arranged in the one end is to parameter, determine the corresponding hoop of described hoop information and get opposite hoop according to the hoop parameter that reads, again will this opposite hoop be defined as the hoop of described loop interface. Receive west on the loop to hoop information such as: node 320 from the loop interface that is positioned at its left side, 320 loop interface of determining its left side of node are the east orientation interface; Equally, if node 320 is received east orientation hoop information on the loop from the loop interface that is positioned at its right side, 320 of nodes determine that the loop interface on its right sides be western to interface.
Certainly, node 320 behind the hoop of having determined self end, also can directly get the opposite hoop of definite hoop, and will this opposite hoop be defined as the hoop of node 320 other ends.
Through behind the aforesaid operations, node 310 might be received the hoop information that self once sent, and also might receive the hoop information from node 320. When node 310 had been received the hoop information that self once sent, node 310 was peeled off this hoop information; When node 310 has been received hoop information from node 320, the priority that the hoop information that 310 of nodes are relatively received comprises and the priority of self, if the priority of node 310 is relatively high, node 310 is determined to send the hoop information of self from the hoop of also determining self as host node according to the hoop collocation strategy that sets in advance again; If the priority of node 310 is relatively low, the hoop information that 310 bases of node are received determines self to comply with the hoop of loop, and the described hoop information that will receive continues to send. As seen, the operation that node 310 carries out when receiving from the hoop information of node 320, the operation of carrying out when receiving hoop information from node 310 with aforesaid node 320 is identical.
Have, if node 320 has been received the hoop information that self once sent, 320 of nodes are peeled off this hoop information again.
In actual applications, also further arrange in the communication node on the RPR ring and seize parameter, seize the Parametric Representation communication node with this and whether have the ability as host node. As: the value of seizing parameter is 1 o'clock, represents communication node and has the ability as host node; The value of seizing parameter is 0 o'clock, and representing communication node does not have ability as host node. In this case, communication node on the RPR ring is after receiving hoop information and determining that self priority is relatively high, what also need further to read self seizes parameter to determine whether self has the ability as host node, if have the ability as host node, described communication node is then determined to send the hoop information of self from the hoop of also determining self as host node according to the hoop collocation strategy that sets in advance again; Otherwise described communication node can only determine self to comply with according to the hoop information of receiving the hoop of loop, and the described hoop information that will receive continues to send.
If added again new communication node on RPR ring shown in Figure 3, the hoop layoutprocedure after then is substantially identical with aforementioned as described in Figure 3 hoop layoutprocedure, distinguishes and only is that the communication node number on the RPR ring increases to some extent.
Embodiment three: deleted communication node on the RPR ring.
Referring to Fig. 4, Fig. 4 is the hoop configuration schematic diagram of the embodiment of the invention three.
In application process, single board default/machine failure might occur in communication node, and this will cause it can't normally carry out hoop configuration even can't proper communication. Suppose that single board default/machine failure has occured Node B 420.
When single board defaults/machine failure occured for Node B 420, Node B 420 was used prior aries self and is set to the shutdown state. Like this, 420 communication informations that self is received of Node B are carried out transparent transmission, and do not carry out other operation, at this moment can think Node B 420 from the deletion of RPR ring, and any appellation in the subsequent descriptions, operation etc. are all irrelevant with Node B 420. Certainly, if Node B 420 can't proper communication, even Node B 420 is the shutdown state so, Node B 420 may also can't normally be received and sent messages.
If Node B 420 is slave node, other communication node on the RPR ring can be used prior art continuation proper communication so, need not additionally carry out other any special operational.
If Node B 420 is host node, when other communication node application prior art on the RPR ring is known Node B 420 fault, send respectively the hoop information of self so. Certainly, other communication node on the RPR ring also can when the described state conversion timing device that arranges is overtime, send respectively the hoop information of self.
As seen, each communication node on the RPR ring all can be received the hoop information that other each communication nodes are sent. The below describes as an example of node A 410 example:
The priority that each hoop information that node A 410 relatively receives comprises and the priority of self, if comparative result is that the priority of node A 410 is relatively high, node A 410 determines from the hoop information that also no longer continues to send as host node from other communication node; If comparative result is that the priority of node C 430 is relatively high, the node C 430 hoop information that 410 bases of node A are received determine self to comply with the hoop of loop, and the hoop information of node C 430 continued to send, and no longer send the hoop information of other communication node.
After node C 430 receives hoop information from each communication node, the priority that each hoop information of relatively receiving comprises and the priority of self, if the priority of node C 430 is relatively high, node C 430 determines from the hoop information that also no longer continues to send as host node from other communication node; If node C 430 determines that the priority of other certain communication node is relatively high, the hoop information of this communication node that 430 bases of node C are received determines self to comply with the hoop of loop, and the hoop information of this communication node continued to send, and no longer send the hoop information of other communication node.
As seen, through behind the aforesaid operations, all communication nodes on the RPR ring can finally be determined a host node, and determine that other communication node is slave node, and all slave nodes have all determined self to comply with the hoop of loop according to the host node hoop.
Have, host node might be received the hoop information that self once sent again, and at this moment host node is peeled off this hoop information.
In actual applications, also further arrange in the communication node on the RPR ring and seize parameter, and carry out follow-up seizing the operation of parameter correlation with this, this operation is identical with corresponding operating among the embodiment two.
By Fig. 4 is described, can find out that Fig. 4 and Fig. 3 have correlation: when the node 310 among Fig. 3 and node 320 are arranged on the RPR ring simultaneously, 320 of node 310 and nodes be on being arranged into the RPR ring time or the state conversion timing device of setting when overtime, carries out respectively with the described identical really fixed ring of Fig. 4 to, the relatively operation such as priority; Difference only is that the communication node number on the RPR ring is relatively less.
Embodiment four: two RPR rings are formed a RPR ring.
Referring to Fig. 5, Fig. 5 is the hoop configuration schematic diagram of the embodiment of the invention four. Among Fig. 5, node A 510, Node B 520, node C 530, node D 540 are former to belong to a RPR ring, and a communication node is wherein arranged is host node, and other communication node is slave node, and each communication node has all been determined hoop; From node A 510, Node B 520, node C 530, node H 550, node I 560, node J 570, node K 580 former another RPR rings that belong to that node D 540 colors are different, and it is host node that a communication node is wherein arranged, other communication node is slave node, and each communication node has all been determined hoop. When networking, node A 510 can be linked to each other with node H 550, node D 540 is linked to each other with node K 580, make the communication node that originally belongs to two different RPR rings belong to same RPR ring.
