Description

The collocation method of a kind of RRPP, system and equipment
Technical field
The present invention relates to communication technical field, particularly relate to collocation method, system and the equipment of a kind of RRPP.
Background technology
In the networking of the network planning and reality is used, adopt the looped network technology to improve the reliability of network usually, the looped network technology realizes intercoming mutually by the shape of some network equipments by ring connected together.In looped network for fear of producing broadcast storm; adopt STP (Spanning Tree Protocol; Spanning-Tree Protocol) Loop Protection mechanism or RRPP (Rapid Ring Protection Protocol; rapid ring protection protocol) Loop Protection mechanism avoids producing broadcast storm; wherein; broadcast storm is meant that too much broadcast data packet has consumed a large amount of network bandwidths, causes normal packet to transmit in network.
In actual applications, the convergence time of STP agreement is subjected to the influence of network topology, convergence time is longer when network diameter is big, can not satisfy transmission quality requirement to data when higher, and the RRPP agreement has shortened the convergence time of looped network, and eliminated the influence of network size, thereby be widely used.Wherein, RRPP is the link layer protocol that is specifically applied to Ethernet ring, when Ethernet ring is complete, can prevent because the broadcast storm that causes of data loopback, and when a link on the Ethernet ring disconnects, can enable backup link rapidly, thus the connectedness of assurance looped network.The RRPP agreement has the following advantages: topological convergence speed fast (being lower than 50ms); The node number is irrelevant on convergence time and the looped network; In phase cross ring topology, the variation of a ring topology can not cause the topology surge of other rings, and transfer of data is more stable, the load balancing of support RRPP ring net, has made full use of the bandwidth of physical link.
In the RRPP agreement; represent the topological scope that the RRPP agreement is controlled by using RRPP domain; wherein; this RRPP domain is by the ID sign of integer representation; one configuration set identical territory ID, control VLAN (Virtual Local Area Network; and the device populations that is interconnected constitutes RRPP domain VLAN) and protection VLAN (or data vlan).Wherein, control VLAN is used to transmit the protocol massages of RRPP; protection VLAN is used to transmit the data message of RRPP; each RRPP domain is furnished with master control VLAN and two control of son control VLAN VLAN; master control VLAN is used to transmit the RRPP protocol massages of main ring, and son control VLAN is used to transmit the RRPP protocol massages of subring, and the RRPP port of main ring should belong to master control VLAN; also will belong to simultaneously son control VLAN, the RRPP port of subring only belongs to son control VLAN.
As shown in Figure 1, the element of a RRPP domain comprises: RRPP ring, control VLAN, protection VLAN, host node, transmission node, fringe node, assistant edge node, wherein, Edge node and assistant edge node is special transmission node.In Fig. 1, Domain (territory) 1 is a RRPP domain, and equipment S1~equipment S6 all belongs to this Domain 1.In RRPP domain 1, comprise two RRPP ring, Ring (ring) 1 is being configured to main ring, when Ring 2 is configured to subring, the control VLAN of RRPP ring is master control VLAN (VLAN 3) and son control VLAN (VLAN 4), among Fig. 1 nodal scheme be 3 all are master control VLAN, nodal scheme be 4 all are son control VLAN; Wherein, the host node of main ring is S1, and the host node of subring is S6; The transmission node of main ring is S2, S3 and S4, and the transmission node of subring is S5.And S3 is a fringe node, and S2 is the assistant edge node.
When the node of configuration in the RRPP domain, a host node must be arranged on each RRPP ring, and a host node can only be arranged, for example the S1 among Fig. 1 is the host node of main ring, S6 is the host node of subring, and host node is the promoter of looped network state active detecting mechanism, also is the policymaker who detects executable operations after the RRPP ring fault; In RRPP ring, other nodes except host node all are transmission nodes, and for example the S2 among Fig. 1, S3 and S4 are the transmission nodes of main ring, and S5 is the transmission node of subring, and transmission node is responsible for transmitting the HELLO message of host node; And Edge node and assistant edge node is special transmission node, is subring and the main ring node when intersecting, and fringe node and assistant edge node must dispose in pairs.For example the S3 of Fig. 1 terminal is a fringe node, and S2 is the assistant edge node.Insert in two ports of RRPP ring at host node and transmission node, one is master port, and another is secondary port, and the port of Edge node and assistant edge node access RRPP ring can also be edge port or public port, wherein, the attribute of each port disposes decision by the user.Host node sends the HELLO message from master port, and as when when secondary port is received this message, then this node place RRPP ring net is complete, when secondary port can not receive this message at the appointed time, and this node place RRPP ring net fault then.
Based on top analysis, when the configuration RRPP ring, there is following shortcoming at present:
Very complicated when the configuration RRPP ring, the port that belongs to RRPP ring on each node all needs the keeper to specify the attribute of this port, being master port or secondary port, is public port or edge port, also needs the keeper to specify fringe node or assistant edge node for each node.More when the RRPP ring node, when being specified one by one by the network manager, the workload of configuration is bigger, and can cause configuration to make mistakes, and brings whole RRPP ring net fault.

Further, when node was fringe node or assistant edge node, on this fringe node or assistant edge node, when port attribute only belonged to subring, then this port was an edge port; When port attribute had both belonged to main ring and also belongs to subring, then this port was a public port; When subring master port attribute is arranged in the public port, public port place node is the assistant edge node, wherein, Edge node and assistant edge node occurs in pairs, for the node that three or three above RRPP ports are arranged on the node, after having determined the assistant edge node, can determine fringe node.
Correspond among the present invention, for node E (fringe node or assistant edge node), port E1 is the secondary port of main ring, port E2 is main ring master port, subring master port, port E3 is the secondary port of subring, after optimizing, port E3 is edge port (attribute of port E3 only belongs to subring), port E2 is public port (attribute of port E2 promptly belongs to main ring and also belongs to subring), and subring master port attribute (E2 is main ring master port, subring master port) arranged among the public port E2, at this moment, public port E2 place node (node E) is the assistant edge node.Among the present invention, the port number of node E and node C is 3, and when node E was the assistant edge node, node C was a fringe node.For node C, port C1 is the main ring master port, port C2 is the secondary port of main ring, the secondary port of subring, port C3 is the subring master port, after optimizing, port C3 is edge port (attribute of port C3 only belongs to subring), port C2 is public port (attribute of port C2 promptly belongs to main ring and also belongs to subring), and there is not subring master port attribute (port C2 is the secondary port of main ring, the secondary port of subring) among the public port C2, at this moment, public port C2 place node (node C) is not the assistant edge node, and this node C is a fringe node.
In sum, each node in the RRPP domain and the RRPP attribute of port are specially: during initial configuration, obtaining node A is the main ring host node, and A1 is the secondary port of main ring, and A2 is the main ring master port; Node G is the subring host node, and G1 is the secondary port of subring, and the G2 subring is a master port.After other nodes were optimized, can obtain Node B was the main ring transmission node, and B1 is the main ring master port, and B2 is the secondary port of main ring; Node C is a fringe node, and C1 is the main ring master port, and C2 is the secondary port of main ring, the secondary port of subring and public port, and C3 is subring master port and edge port; Node D is the main ring transmission node, and D1 is the main ring master port, and D2 is the secondary port of main ring; Node E is the assistant edge node, and E1 is the secondary port of main ring, and E2 is main ring master port, subring master port and public port, and E3 is secondary port of subring and edge port; Node F is the subring transmission node, and F1 is the subring master port, and F2 is the secondary port of subring.
Step S405 is the RRPP attribute of above-mentioned each node that gets access to the attribute modification of transmission node, is the RRPP attribute of above-mentioned each port that gets access to the attribute modification of transmission node port.
Wherein, be that the RRPP attribute of above-mentioned each port that gets access to specifically comprises with the attribute modification of transmission node port: the control vlan information of described transmission node port is revised as the port controlling vlan information that gets access to; Be revised as port domain-name information, port ring information and the port information that gets access to port domain-name information, port ring information and port information with the transmission node port, and port ring information is the ring at port place is main ring and/or subring, port information is that port is master port and/or secondary port, and port is edge port or public port.
Correspond among the present invention, with the attribute modification of transmission node B is common main ring transmission node, transmission node C is special transmission node (fringe node), transmission node D is common main ring transmission node, transmission node E is special transmission node (assistant edge node), and transmission node F is common subring transmission node.
Modification to port B1 attribute is specially: the control vlan information that the control vlan information of B1 is revised as port A2, it is 1 (territory at main ring place) that the domain-name information of B1 is revised as domain name, the port ring information of B1 is revised as main ring, the port information of B1 is revised as the main ring master port.Same, other node among corresponding the present invention after getting access to the RRPP attribute of port, all can be made amendment to the attribute of this port, and modification process is identical with above-mentioned modification to port B1, does not repeat them here.
Step S406, after the RRPP attribute of each node in RRPP domain and the RRPP attribute configuration of each port were finished, each node and each port were finished the communication of RRPP ring net equipment room according to the attribute of self.
Wherein, when network initial condition configuration RRPP attribute, HELLO message from the secondary port of host node (A1 and G1) transmission, when being received default number of times by the host node at this pair port place, then the RRPP attribute configuration of the RRPP attribute of each node in the RRPP domain and each port is finished, and stops to send the HELLO message from this pair port, does not promptly re-use this pair port and sends this HELLO message, the numerical value of number of times for choosing according to historical experience that should be default is generally 3; Host node then can periodically send the HELLO message, to detect the property finished of looped network.
Step S407, the looped network state is complete when going forward side by side the line link communication, and when the network topology of looped network changes or looped network when breaking down, transmission node will recomputate the RRPP attribute of port and the RRPP attribute of node.Wherein, the mode that changes of network topology includes but not limited to that new switch (node) joins this RRPP domain or has switch to leave this RRPP domain.
Among the present invention, after the looped network initial configuration is finished, whether host node on the looped network and transmission node will detect looped network and break down, the mode of this detection comprises: (1) host node is by the state of polling mechanism active detecting looped network, processing procedure is specially: host node cycle send the HELLO message from master port, pass through each transmission node successively, and on ring, propagate.When the transmission node on the looped network all is in the UP state, (not breaking down), the secondary port of host node will receive the HELLO message of autonomous node master port, the looped network state is complete, and for the data message on the anti-stop ring forms the broadcasting loop, host node will block secondary port; When having transmission node to be in the Down state on the looped network (generation link failure), the secondary port of host node can't receive the HELLO message of autonomous node master port in the default time, looped network generation link failure, host node switches to Failed (fault) state with state, decontrol secondary port, and from the master, all transmission nodes refresh MAC (Media Access Control on secondary port transmission COMMON-FLUSH-FDB (refreshing mac address forwarding table) the message notifying ring, medium access control) list item and ARP (AddressResolution Protocol, address resolution protocol)/ND list item.(2) host node detects the state of looped network by link failure notification mechanism, processing procedure is specially: the port Link State of host node monitoring oneself, behind host node master port Down, host node perception link failure, decontrol secondary port, and send from secondary port that all transmission nodes refresh MAC address entries and ARP/ND list item on the COMMON-FLUSH-FDB message notifying ring.(3) whether transmission node detects this node and breaks down, processing procedure is specially: during RRPP port generation link DOWN on the transmission node, this transmission node will send LINK-DOWN message notifying host node from another RRPP port with the non-working port pairing, host node is after receiving the LINK-DOWN message, decontrol secondary port, state is switched to the Failed state, and refresh MAC address entries and ARP/ND list item from major and minor all transmission nodes of port transmission COMMON-FLUSH-FDB message notifying.Wherein, above-mentioned COMMON-FLUSH-FDB message is initiated by host node, notification transmission node updates MAC address entries and ARP/ND list item separately when RRPP ring is moved to the Failed state, node is received this message that the subring host node sends on the main ring, also need refresh MAC address entries and ARP/ND list item.
Among the present invention, when the topology of network changes, for avoiding the directed mistake of message, host node also needs to refresh MAC address entries and ARP/ND list item, and promptly major and minor all transmission nodes of port transmission COMMON-FLUSH-FDB message notifying from host node refresh MAC address entries and ARP/ND list item.For example, when having new switch to join RRPP domain, this switch can send the information that adds to host node, and host node sends COMMON-FLUSH-FDB message all transmission nodes to looped network after receiving this information.
