Embodiment
In existing RRPP ring net; Owing to the choke point can only be arranged on the problem that host node causes occurring easily bigger time-delay and load; The present invention proposes a kind of method that the choke point is set; According to the RRPP ring net choke point is set on the corresponding transmission node flexibly, each transmission node reduces flow forward delay interval and transmission node load to the hop count of host node transmitted traffic in the RRPP ring net thereby reduce.
Concrete, the present invention provides a kind of RRPP of setting the method for choke point, is applied to quick ring protection agreement RRPP ring net, comprises a host node and a plurality of transmission node in the said RRPP ring net, and as shown in Figure 2, this method comprises:
Step 201, said host node sending node probe messages is obtained the number of transmission node in the said RRPP ring net;
Step 202, said host node is confirmed the transmission node as the choke point according to the number of transmission node in the said RRPP ring net;
Step 203, said host node are sent to the transmission node that is chosen to be the choke point and are blocked message, notify the said transmission node blocking remote port that is chosen to be the choke point.
Introduce the method for the RRPP of setting provided by the invention choke point in detail below in conjunction with concrete application scenarios.Wherein, the RRPP ring net is an example with a host node, 8 transmission nodes.Wherein, The message that host node sends to transmission node comprises node probe messages, the obstruction message of RRPP protocol massages form and blocks and remove message; The node probe messages is specially the improvement hello packet, blocks message and is respectively Node-Down message and Node-Undown message with obstruction releasing message.Host node can also send the integrality that hello packet is surveyed the RRPP ring net to transmission node.
In the application scenarios of the present invention, do not dispose the choke point in the RRPP network as yet, at this moment, host node selects corresponding transmission node as the choke point through improved hello packet, specifically shown in Fig. 3 a, may further comprise the steps:
Concrete, the form that improves hello packet is as shown in table 1:
Table 1
Wherein, The RRPPTYPE value is 5; In the RRPP agreement, represent hello packet; Improve hello packet further first RESERVED field of hello packet be set to NodeNo, be used to write down the node ID of RRPP ring, each node that receives this improvements hello packet adds 1 with the value of NodeNo and then sends to next node.
Should use in the scene, host node can put 0 with the NodeNo field, the 0th node of expression RRPP ring when master port sends improvement HELLO message; After the next node of host node is received and improved the HELLO message, change oneself node ID into NodeNo+1, the value of revising the NodeNo field in the message simultaneously is NodeNo+1, and the like; Last host node can be learnt the interstitial content on the ring when secondary port receives to improve the HELLO message.As shown in Figure 4, host node receives when improving hello packet, and obtaining the NodeNo that improves in the hello packet is 8, and host node knows that the transmission node number in the RRPP ring net is 8.
Should use in the scene, host node can also be put n with the NodeNo field when master port sends the improvement hello packet, and n is an arbitrary number, the 0th node of representative ring; After first is received and improves the HELLO message, change oneself node ID into NodeNo+1, the NodeNo field of revising simultaneously in the message is NodeNo+1, and the like; Last host node receives that at secondary port when improving the HELLO message, obtaining and improving the NodeNo that carries in the hello packet is n+8, and the NodeNo of this NodeNo and initial setting up is subtracted each other, and the transmission node number of obtaining in the RRPP ring net is 8.
Should use in the scene, host node does not receive when improving hello packet at last, and host node is judged RRPP ring network chain road fault, host node warning reminding user RRPP ring net connection error.
Concrete, host node can be selected the transmission node as the choke point according to multiple mode.For example, host node can be with the intermediate transmission node of RRPP ring net as the choke point, and like this, the maximum delay of RRPP ring net and load will be host node 1/2 during as choke points.If the transmission node of RRPP ring net is an even number, the master port of chosen distance host node is perhaps assisted the nearer transmission node of port as the choke point according to actual needs.
Host node can also be provided with other transmission nodes as the choke point according to actual needs flexibly; The parameter that for example influences data transmission efficiency when the bandwidth of each transmission node etc. is not simultaneously; Can the choke point be set according to actual conditions, with maximum delay and the load that reduces the RRPP ring net as far as possible.
After the choke point receives the Node-Down message, break off remote port and be connected with the link of next node.Concrete, the form of Node-Down message is specifically as shown in table 2:
Table 2
The value of RRPPTYPE is set to 100 among the present invention, expression Node-Down message.The choke point that receives this RRPP protocol massages knows that this message is the Node-Down message, the blocking remote port according to the value of the RRPPTYPE that wherein carries.
After having disposed the choke point in the RRPP ring net, host node cycle property transmission probe messages is surveyed the integrality of RRPP ring net.Should use in the scene, improve hello packet and obtain in the RRPP ring net the transmission node number, also can be used as the integrality that probe messages is surveyed the RRPP ring net except can be used as the node probe messages; At this moment; Host node no longer need send hello packet, and shown in Fig. 3 b, detailed process is following:
Concrete; Each node in the RRPP ring net has two ports; After transmission node receives the improvement hello packet that host node sends, wherein NodeNo field value added 1 after, continue to send from the remote port of this transmission node and should improve hello packet to next node.If host node can receive this improvement hello packet from secondary port after sending the improvement hello packet through master port in Preset Time, then host node judges that the RRPP ring net is complete, execution in step 306; Otherwise host node does not receive that from secondary port when improving hello packet, host node judges that the RRPP ring net is imperfect, execution in step 305 in Preset Time.
The process of confirming new transmission node as the choke point in this step is with same or similar in the step 302, and therefore, detailed process can refer step 302.
Concrete, the form of Node-UnDown message is specifically as shown in table 3:
Table 3
The value of RRPPTYPE is set to 101 among the present invention, expression Node-UnDown message.The choke point that receives this RRPP protocol massages knows that according to the value of the RRPPTYPE that wherein carries this message is the Node-UnDown message, removes the obstruction of remote port.
The choke point that receives the Node-Down message keeps the blocked state of its remote port.
After having disposed the choke point in the RRPP ring net, host node cycle property transmission probe messages is surveyed the integrality of RRPP ring net, and this probe messages can also be hello packet, and detailed process is as shown in Figure 4, comprising:
After the choke point receives the Node-Down message,, then keep its blocked state if its remote port is in blocked state; If its remote port is not in blocked state, then be set to blocked state.
At this moment; Owing to improve the number that hello packet just is used for obtaining RRPP ring net transmission node; Be not used in the integrality of surveying the RRPP ring net, therefore, the transmitting time that host node improves hello packet can be provided with according to actual needs flexibly; Whether for example be set to the transmission of host node cycle property and improve hello packet, judging thus increases in the RRPP ring net or has deleted transmission node; After perhaps in each RRPP ring net, reconfiguring transmission node by the user, host node sends and improves hello packet, confirms the choke point.
In other application scenarioss of the present invention, RRPP ring net system can the initial configuration host node as the choke point, then confirm transmission node when host node as the choke point; And detect the RRPP ring net whether complete after; As shown in Figure 5, when testing result when being complete, execution in step 501; Otherwise, execution in step 502:
Through adopting method provided by the invention; Host node obtains the transmission node as the choke point according to the number of transmission node in the RRPP ring net; Notice is perhaps removed the obstruction of port as the transmission node port blocked of choke point; Thereby the position of choke point at the RRPP ring net is set flexibly, reduces to occur in the RRPP ring net chance of bigger time-delay or load, improve RRPP ring net ability.
The present invention provides a kind of RRPP of setting the equipment of choke point, is applied to quick ring protection agreement RRPP ring net, comprises a host node and a plurality of transmission node in the said RRPP ring net, and as shown in Figure 6, this equipment comprises:
