Background technology
The reliability of raising such as the key network nodes such as data center becomes the problem that the user is concerned about most gradually, and the most frequently used mode is to adopt Redundancy Design.Be such as network nodes such as data centers symmetrical redundant node is set, perhaps for network link, redundant link is set, so that when a network node or a network link break down, can be fast by flow switch on redundant node or redundant link, reduce the time of service disconnection, improve system reliability.
Data center's the most frequently used reliability network design is the network composition proposal of Multiple Spanning Tree Protocol (MSTP) in conjunction with rapid ring protection protocol (RRPP), but, along with the development of business, the network of data center forms and the trend that some are new occurred.The most outstanding is in some large-scale gardens, a plurality of data centers are arranged in the building of a plurality of dispersions, the client generally can link together a plurality of building by a RRPP ring net, with outside wide area network, by multiprotocol label switching (MPLS), is connected, as shown in Figure 1 simultaneously.Wherein, RRPP is a link layer protocol that is applied to Ethernet ring, when Ethernet ring is complete, can prevent the broadcast storm that data loopback causes, when a link disconnects on Ethernet ring, can recover rapidly the communication path between each network node on looped network.
The MPLS network is modal is VPLS, and as shown in Figure 2, switch A, B, C and D are as the PE equipment of VPLS, and the master port of the master on RRPP ring (master) node is opened, secondary port block.On RRPP ring, the Primary port and secondary port of host node is difference to some extent on function, and in this simple declaration once: the master port of host node is used for sending the loop probe messages, and secondary port is used for receiving the loop probe messages; When RRPP ring is in health status, the secondary port of host node is blocking data VLAN logically, only allows the message of controlling VLAN to pass through; When RRPP ring is in off-state, the secondary port of host node is unblocking, the message of forwarding data VLAN.When the RRPP ring shown in Fig. 2 during in health status, in order to prevent that double situation from appearring in data center's 2 to LAN1 direction broadcast packets, link between switch C and switch D does not configure the VLAN of VPLS business, normal Business Stream is forwarded by switch A-B-C-F, as shown in dotted arrow in Fig. 2.
If switch C breaks down, the control message that host node sends from master port can't receive by secondary port, thereby determine the RRPP ring fault, host node is the message of switch D open auxiliary port repeat data vlan, form the forward-path of switch A-D-E-F, as shown in dotted arrow in Fig. 3.The service outage duration of this handoff procedure is very little, usually in the 50ms left and right.
If it is normal that switch C recovers, host node on RRPP ring is the secondary port of switch D rapid occlusion, but C just recovers due to switch, also need a route recovery process, and the switch in the MPLS network, switch A and B also do not have study to arrive the route of data center 2 by switch C, therefore, will cause the message of up data vlan to be dropped at switch C place, the message of descending data vlan is dropped on switch D, as shown in Figure 4.Because route learning is a longer process, therefore, switch C will bring the service disconnection of long period after recovering normally, can reach the 50s left and right break period.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the drawings and specific embodiments, describe the present invention.
Method provided by the invention mainly comprises: when transmission node newly adds RRPP ring, the host node on this RRPP ring notifies this transmission node in routing failure (Route-Down) state, so that host node does not block secondary port; When this transmission node detects the MPLS network and can reach to the route of this transmission node, the host node on this RRPP ring notifies this transmission node in route recovery (Route-UP) state, so that host node blocks secondary port.
Below still take framework shown in Fig. 1 as example, by specific embodiment, said method is described in detail.
Can increase a kind of RRPP in the present invention newly and control message, type is route indication (Route-Ready) message, and this Route-Ready message sends to host node by transmission node, is divided into Route-Up and Route-Down two states.
Transmission node on RRPP transmission ring, i.e., during the switch C fault recovery in Fig. 4, send to host node the Route-Ready message that carries the indication of Route-Down state immediately.Particularly, during switch C fault recovery, can receive the RRPP control message that host node sends on RRPP ring by master port, this RRPP controls the indication information that message comprises RRPP domain.After switch C receives this RRPP control message, for example hello (hello) message or health (Health) message, switch C confirms self newly to add this RRPP ring, and can control the indication information that obtains RRPP domain message from this RRPP, now, switch C sends to host node the Route-Ready message that carries the indication of Route-Down state on RRPP ring, as shown in Figure 5.It should be noted that, the present embodiment is usingd switch C fault recovery as a kind of example that newly adds RRPP ring, and the present invention also is applicable to other situation that newly adds RRPP ring, for example, and the situation of a switch of new configuration on RRPP ring.
In the present embodiment can be in advance on switch C IP address of configuration for carrying out the MPLS network, to the route of this switch C, whether can reach.The IP address of this configuration can be the IP address of the PE in the MPLS network, can be configured according to actual network composition situation, for example, the IP address of configuration switch A on switch C in advance, the IP address of switch A is 202.1.1.1, configures a RRPP order for RRPP ring on switch C: rrpp route-ready 202.1.1.1enable.
When switch C fault recovery, switch C starts the IP address of configuration is periodically detected, once switch C be detected, to this IP address, can reach, and as shown in Figure 5, determines that the MPLS network can reach to the route of switch C.In the process of the route of MPLS network to switch C before can reaching being detected, the message forwarding path of data vlan still as shown in phantom in Figure 5, by the secondary port repeat of host node.
Even if being switch D, host node the RRPP recovery detected normally, the RRPP sent from master port controls message and can receive from secondary port, but the Route-Ready message due to the Route-Down state that the carries indication that receives switch C transmission, switch C wouldn't carry out the port switching, do not block secondary port, but continue to adopt secondary port to carry out the message repeating of data vlan.
Particularly, switch C carries out periodically detection mode to the IP address of configuration and can be: take the IP address of this configuration periodically sends BFD detection messages or heartbeat ping message etc. as destination address.For example, periodically send the BFD detection messages of purpose IP address for the IP address of configuration, if receive the BFD back message using in the setting-up time after transmission, determine that this IP address can reach, otherwise determine that this IP address is unreachable.
Once router C determines the MPLS network and can reach to the route of this router C, stops sending the Route-Ready message that carries the indication of Route-Down state.Host node does not receive the Route-Ready message that carries the indication of Route-Down state in setting-up time, carries out the port switching, blocks the message repeating function of secondary port to data VLAN.
Perhaps, once router C determines the MPLS network, to the router of this router C, can reach, to host node, send the Route-Ready message that carries the indication of Route-Up state.Host node carries out the port switching after receiving the Route-Ready message that carries the indication of Route-Up state, blocks the message repeating function of secondary port to data VLAN.
As shown in Figure 6, after host node blocks the message repeating function of secondary port to data VLAN, because the link between switch C and switch D does not configure VLAN, therefore, according to the route LAN1 recovered, to the data forwarding paths between data center 2, revert to switch A-B-C-F.
