Description
Technical field
The utility model belongs to technical field of network equipment, and specifically, relating to a kind ofly increases inter-exchange transmission bandwidth and realize the device of link redundancy backup.
Background technology
Along with the explosion of network size and application, network becomes part indispensable in social life day by day, the communication of enterprise and individual with exchange the use all be unableing to do without network.Along with enterprise is to the increase of mesh dependence, network must be safe and reliable, once network service occurs unavailable, may have a strong impact on productivity and the profit of enterprise.Realize higher availability, avoid occurring causing network unavailable due to Single Point of Faliure.Should redundant link be had between the overall situation two communication nodes, and carry out the automatic management of topology.
Redundant link operation concrete principle be: switch A and B all by two links respectively on be linked to switch C and D, wherein a link is primary link, be in active state and carry out normal exchanges data, an other link is backup link, need its obstruction can not be carried out exchanges data, to avoid the generation of data loopback; (generally include: the connecting line fault of primary link when primary link breaks down, the equipment of primary link opposite end or port failure) and when disconnecting, need the obstruction cancelling backup link automatically, make it normally exchange, so just can realize the redundancy backup of link.
When primary link breaks down, system has the function automatically opening backup link.Normal convergence time is 30 seconds, and that is link is from breaking down, and to again recovering, needs the time of 30 seconds, and this can not meet far away in 50 milliseconds that present operator proposes and recovers the requirement of fault.And, traditional Spanning-Tree Protocol produces a tree topology based on whole switching network, all VLANs share a spanning tree, this structure can not carry out the load balancing of network traffics, make some switching equipment busier, and other switching equipment are very idle, thus it is wide to reduce net.
