Background technology
Along with society to the dependent increase of information, network is also increasing to the influence of people's daily life, in case network breaks down, will cause great impact and loss to the normal operation of society.Can how making up safe bearer network becomes pendulum most realistic problem in face of each operator, provide stable ripe protection mechanism also to determine the success or failure that its multi-service and emerging service are carried out.
In the last few years, based on the voice of local area network (LAN) and the deployment of multimedia application, the performance of local area network (LAN) infrastructure bottom became most important along with increasing.The availability of each network components all is indispensable, and not only wide area network link, ISP and route network should have redundancy, and bridge path also should have redundancy.Double-ascending network is one of the networking of using commonly used, and its operation principle is: networking is blocked redundant link through Spanning-Tree Protocol, plays the backup effect, when the active link fault, flow is switched to reserve link, thereby protecting network is unimpeded.Though this scheme can realize the demand of client's redundancy backup on the function, on performance, but can not reach a lot of users' requirement.
Spanning-Tree Protocol STP (Spanning Tree Protocol) can provide path redundancy, uses STP to make and have only an active path in two terminals, and force certain backup path to be in stand-by state.If the active path part in the generation tree is unavailable or the STP value has changed, spanning tree algorithm can recomputate spanning-tree topology, and rebulids connection through starting backup path.The convergence time of Spanning-Tree Protocol is crucial; This will have influence on network performance; 30 to 60 seconds time of STP needs is detected these variations and reconfigures, and this is a very disadvantageous performance parameter for the high-end Ethernet switch that is applied to the carrier class network core.In order to improve the convergence time of Spanning-Tree Protocol, RSTP has been proposed.
RSTP RSTP (Rapid Spanning Tree Protocol) sets up loop-free tree network through rapid spanning-tree algorithm blocking part redundant path in switching network.The rapid spanning-tree algorithm that RSTP adopted is a distributed algorithm, and it selects a switch as the tree root that generates tree, and algorithm is that the different port on every switch distributes the port task.RSTP has defined five kinds of port roles according to the effect of port in active topology:
Inactive port (disabledport),
Root port (root port),
Designated port (designated port),
Substitute port (alternate port),
Backup port (backup port).
No matter port is born any task; They can become under situation about breaking down provides internuncial alternative port or standby port; RSTP has guaranteed after switch ports themselves or local area network (LAN) break down; Recover network quickly and connect, the time that reconfigures and recover to serve is reached below level second, but this still can not satisfy the high-end Ethernet switch of carrier class network core.
Though adopt the looped network solution can improve constringency performance, bigger limitation is arranged in networking, need adopt same area to intersect the configuration of ring for double-ascending network, complexity is higher.
