Description

Method and the routing bridge of maintenance of neighbor relation in a kind of TRILL network
Technical field
The present invention relates to communication technical field, particularly method and the routing bridge of maintenance of neighbor relation in a kind of TRILL network.
Background technology
It is the L2 network standard that IETF recommends that multichain connects transparent interconnection (TRILL).TRILL has very high importance, be connected because large-scale data center starts to utilize the new technologies such as Ethernet optical-fibre channel (FCoE) that storage transmission and IP transmission are fused to Ethernet, and the Spanning-Tree Protocol of standard (STP) will no longer applicable UNE or the expansion of ultra-large type data center.Along with the raising of FCoE employing rate, enterprise stores other agreements that start to add in IP network.From point of view from a storage, As time goes on, TRILL at least can replace the STP agreement generally using on L2 network.
In TRILL network, each RB uses other RB equipment on hello packet and link to carry out alternately.Between RB on same link, elect DRB, determine that by DRB follow-up encapsulation TRILL controls the assigned vlan of message and data message, enables the appointment message repeating port (AVF) of VLAN for the each VLAN of enabling on link distributes unique sending and receiving port of specifying as this.Be responsible on data message relevant this VLAN in local network, sending TRILL network as the RB port of AVF, use assigned vlan to carry out being sent to by TRILL networking after TRILL encapsulation the object RB of far-end.At the object RB of far-end by after the TRILL data message decapsulation receiving, by AVF port repeat in local network.
The same with other Routing Protocols of three layers, TRLLL agreement also on link, carries out neighbours' discovery by hello packet and neighborhood is safeguarded.But with three layers of Routing Protocol are different, because TRILL agreement runs on double layer network, so agreement regulation, for DRB, the hello packet of finding for neighbours need to enable VLAN at each and send; For non-DRB, hello packet need to send in assigned vlan and the VLAN as AVF.
In actual networking application, the forwarded upstream port of TRILL network tends to enable a lot of VLAN, by the regulation of TRILL agreement, need in each VLAN, send for the hello packet that neighbours find and neighborhood is safeguarded, and, because the acquiescence refresh time interval of hello packet is very short, on DRB, acquiescence sent once every 3 seconds, on non-DRB, send once every 10S, so, when a port enables VLAN more time, have a large amount of hello packet and be sent out.A large amount of hello packet has not only consumed link bandwidth, but also has wasted the CPU disposal ability of RB.
Summary of the invention
In view of this, the invention provides method and the routing bridge of maintenance of neighbor relation in a kind of TRILL network.Can reduce the quantity that sends hello packet, reduce the consumption of link bandwidth, improve the CPU disposal ability of RB.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that
A method for maintenance of neighbor relation in TRILL network, described method comprises:
Current RB receives the hello packet that in TRILL network, other RB of same link send, and carry out DRB election according to the hello packet receiving, if self is elected as DRB, selected assigned vlan and in assigned vlan the cycle send hello packet and notify other RB; If other RB are elected as DRB, receive the hello packet that carries assigned vlan that DRB sends, obtain described assigned vlan and cycle transmission hello packet in described assigned vlan.
A routing bridge for maintenance of neighbor relation in TRILL network, described routing bridge comprises: receiving element, election unit, transmitting element and reception acquiring unit;
Described receiving element, the hello packet sending for receiving other RB of TRILL network same link;

Referring to Fig. 1, Fig. 1 be in the embodiment of the present invention in TRILL network the method flow diagram of maintenance of neighbor relation.Concrete steps are:
Step 101, current RB receives the hello packet that in TRILL network, other RB of same link send, and carries out DRB election according to the hello packet receiving.
This step is the hello packet sending between RB before DRB election to carry out DRB election consistent with existing realization, the hello packet that enables to send within the scope of VLAN at self.
Step 102, if current RB is elected as DRB, selected assigned vlan and in assigned vlan the cycle send hello packet and notify other RB.
In this step, after the selected assigned vlan of DRB, only in this assigned vlan, the cycle sends hello packet, and other enable not send in VLAN hello packet.
Step 103, if other RB are elected as DRB, receives the hello packet that carries assigned vlan that DRB sends, and obtains assigned vlan and cycle transmission hello packet in this assigned vlan.
In this step, other RB are elected as DRB, and current RB is that the RB that is not elected as DRB obtains after assigned vlan, and only in the assigned vlan obtaining, the cycle sends hello packet.
If current RB receives the hello packet in non-described assigned vlan, in the non-described assigned vlan of correspondence, send and reply hello packet, and re-start DRB election according to the hello packet receiving.
If current RB is at the DRB re-electing, while being elected as DRB, again selected assigned vlan and in described selected assigned vlan again the cycle send hello packet and notify other RB; If when other RB are elected as DRB, receive the hello packet that carries again selected assigned vlan that DRB sends, obtain again selected assigned vlan and cycle transmission hello packet in the assigned vlan that this is selected again.
If current RB is elected as DRB, and described assigned vlan be send the hello packet in non-described assigned vlan RB enable VLAN, using described assigned vlan as again selected assigned vlan.
After DRB election, receive the hello packet of RB transmission that newly adds network in non-designated VLAN time, the RB that had participated in election sends hello packet in assigned vlan, therefore only has the RB newly adding just may in certain VLAN outside assigned vlan, send hello packet.If receive such message, in corresponding VLAN, can send and reply hello packet, and re-start DRB election according to the hello packet of new RB.If due to the more high reason of RB priority newly adding, DRB changes, check the assigned vlan carrying in the hello packet of the DRB re-electing out, if assigned vlan wherein changes, automatically change sends hello packet in assigned vlan, and if the VLAN that enables of the RB newly adding comprise the assigned vlan before re-electing, assigned vlan is constant as far as possible, use original assigned vlan, avoid the frequent variations of assigned vlan to cause unstable networks.The selected of assigned vlan should obtain from the common factor that enables VLAN of each RB.
If current RB is DRB, this current RB also distributes respectively unique AVF for respectively enabling VLAN on link, and cycle transmission hello packet is notified other RB in assigned vlan.
If current RB is not elected as DRB, what this current RB reception DRB sent carries the hello packet that respectively enables the AVF of VLAN on link, obtain the VLAN that enables that is assigned with AVF of self, when the cycle sends hello packet in assigned vlan, carry from the AVF as the described VLAN of enabling.
