Embodiment
The present invention proposes a kind of up method of RRPP ring shunt that realizes, and is applied to the RRPP ring that comprises a host node and multiple transmission nodes, and this host node comprises Primary port and secondary port; As Fig. 2 be the present invention propose realize along separate routes up method flow diagram of RRPP ring, the method comprises:
Step 201: host node is searched apart from host node transmission node farthest, is defined as host node agency by this transmission node.
Step 202: host node is sent and selected along separate routes hello packet, this shunt to select hello packet to carry described host node agency's mark by master port;
Step 203: transmission node receives described shunt and selects hello packet, judge according to the host node agent identification in this message whether self is host node agency, if, the port that receives this message is defined as to time secondary port, another port is defined as to time master port, inferior secondary port is switched to blocked state on data vlan; Otherwise, continue to forward this shunt and select hello packet;
Step 204: when host node agency receives the common hello packet of autonomous node by inferior secondary port, send host node by inferior master port and act on behalf of hello packet;
Step 205: host node receives described host node by secondary port and acts on behalf of after hello packet switches to forwarding state by described secondary port, and sends Common_Flush_FDB message by Primary port and secondary port on data vlan.
After said method step 205, may further include:
Step 206: transmission node receives this Common_Flush_FDB message, refreshes the mac address forwarding table of self according to this message.
By said process, the flow that can realize RRPP ring divides two-way up, that is, flow goes upward to host node by a host node agency point two-way.The prerequisite of this establishment is that host node is the outlet of the upper flow of ring.
In above-mentioned steps 201, host node is searched apart from the mode of host node transmission node farthest and can is:
Host node sends collecting topology hello packet by master port;
When each transmission node in RRPP ring receives collecting topology hello packet, the mark of self is packed into this collecting topology hello packet, and continues to forward this collecting topology hello packet;
Host node receives collecting topology hello packet by secondary port, obtains the mark of the each transmission node carrying in this collecting topology hello packet, searches apart from all transmission nodes farthest of the Primary port and secondary port of host node according to described mark.
Have 2 apart from host node transmission node farthest if found, host node can be defined as wherein any one host node agency.
In above-mentioned steps 203, transmission node is judged after acting on behalf of as host node, may further include: host node is set and acts on behalf of hello packet timer, the timing cycle that described host node is acted on behalf of the timing cycle of hello packet timer and the common hello packet timer of host node is identical;
Like this, when host node agency receives first common hello packet in host node is acted on behalf of the timing cycle of hello packet timer, can send host node by inferior master port and act on behalf of hello packet; If also receive follow-up common hello packet in this timing cycle, no longer trigger its transmission host node and act on behalf of hello packet.
Host node receives first host node while acting on behalf of hello packet processing procedure that what above-mentioned steps 205 was described is; Once after secondary port is switched to forwarding state and sends Common_Flush_FDB message, when receiving host node subsequent cycle and acting on behalf of hello packet, host node only need maintain current state, and need not perform step the process described in 205.
In said process, collecting topology hello packet, along separate routes select hello packet and host node to act on behalf of hello packet in the reserved field of self, to identify respectively.These three kinds of hello packet are special hello packet that the present invention defines, and in addition, also periodically send common hello packet in system.Below various hello packet are elaborated:
Common hello packet---in reserved field, selecting 4bit territory is common hello packet for identifying this message, and reserved field value is 0000; Be common loop probe messages, send by acquiescence detect cycle, not affected by other flow processs;
Collecting topology hello packet---in reserved field, selecting 4bit territory is collecting topology hello packet for identifying this message, and reserved field can value be 0001, collects for encircling upper topology, periodically sends, and the cycle can be set to 30 minutes;
Select along separate routes hello packet---in reserved field, select 4bit territory for identifying this message for selecting along separate routes hello packet, reserved field can value be 0010, notify the transmission node farthest of choosing (being host node agency) for host node, in this hello packet, carry the mark of the transmission node of choosing.Other transmission nodes are received rear transparent transmission, only have selected transmission node to receive that rear discovery, to oneself, just can process;
Host node is acted on behalf of hello packet---and in reserved field, selecting 4bit territory is that host node is acted on behalf of hello packet for identifying this message, reserved field can value be 0011, the hello packet that host node agency sends, for notifying host node that secondary port is switched to forwarding state on data vlan.
After above-mentioned steps, when RRPP ring there is link failure or because of RRPP ring on increase new node cause loop disconnect time, further carry out following steps:
In the time that host node is received Link_down message or host node and is not received host node act on behalf of hello packet in the timing cycle of continuous three common Hello timers by master port or secondary port, the secondary port of host node still keeps forwarding state on data vlan, but the state of RRPP ring is set to failure (Failed) state, to remind network management personnel to check loop;
Or, in the time that host node agency receives Link_down message, inferior secondary port is switched to forwarding state on data vlan, and recover the transmission node identity of self,, receive by inferior secondary port after the common hello packet of autonomous node, no longer common hello packet is processed, but common hello packet described in direct transparent transmission.
After loop fault is disengaged and lays equal stress on and newly set up RRPP ring, repeat above-mentioned steps 201, reselect host node agency, realize flow on RRPP ring up along separate routes.

Step 304: host node is sent along separate routes and selected hello packet by master port, and this shunt selects to carry in hello packet the mark of encoder F, and the reserved field value of this message is 0010.
Step 305: select hello packet to transfer to successively encoder A-F along separate routes;
For encoder A-E, in the time receiving that hello packet is selected in shunt, judging according to the mark of the encoder F wherein carrying self is not the host node agency that host node is selected, and continues to forward and selects along separate routes hello packet;
For encoder F, in the time receiving that hello packet is selected in shunt, judging according to the mark of the encoder F wherein carrying self is the host node agency that host node is selected, the port that receives this message is defined as to time secondary port, another port is defined as to time master port, inferior master port is switched to blocked state on data vlan, and host node is set acts on behalf of hello packet timer.Wherein, to act on behalf of the timing cycle of the timing cycle of hello packet timer and the common hello packet timer of host node identical for host node.
Step 306: encoder F receives by inferior secondary port after the common hello packet of autonomous node, no longer this common hello packet of transparent transmission; But in host node is acted on behalf of the timing cycle of hello packet timer, in the time receiving common hello packet for the first time, send host node by inferior master port and act on behalf of hello packet, the reserved field value of this message is 0011.
Step 307: host node is acted on behalf of hello packet and transferred to host node by encoder G-K, host node receives this host node by secondary port and acts on behalf of after hello packet, secondary port is switched to forwarding state on data vlan, but on host node, the state of RRPP ring is still closed loop state, the relieving that is secondary port on RRPP host node is not because receive Link_down message, but owing to continuing to receive that host node acts on behalf of hello packet; Host node also sends Common_Flush_FDB message by Primary port and secondary port.
Step 308: when each encoder in loop receives this Common_Flush_FDB message, refresh the mac address forwarding table of self.
So far, realized the shunt of monitoring RRPP ring flow up.Fig. 4 adopts the embodiment of the present invention to realize the structural representation of up along separate routes monitoring RRPP ring.As shown in the arrow in Fig. 4, by encoder F, through left and right, two links go upward to host node to flow respectively, thereby have avoided all flows to transmit via a direction, avoid performance bottleneck.
After this,, in the time that link failure appears in monitoring RRPP ring or increase new node on RRPP ring and cause loop to disconnect because of monitoring, host node Proxy Restore need to be become to common encoder, and propose alarm by host node to webmaster.Specifically comprise the following steps:
Step 309: in the time that host node is received Link_down message or host node and do not received host node act on behalf of hello packet in the timing cycle of continuous three common Hello timers by master port or secondary port, think that network breaks down, the secondary port of host node still keeps forwarding state on data vlan, but the state of RRPP ring is set to Failed state, to remind network management personnel to check loop.
Step 310: in the time that encoder F also receives Link_down message, inferior secondary port is switched to forwarding state on data vlan, and recover the transmission node identity of self,, receive by inferior secondary port after the common hello packet of autonomous node, no longer common hello packet is processed, but direct this common hello packet of transparent transmission.
Certainly, above-mentioned steps 309 and 310 is actions that host node and encoder F carry out respectively, there is no fixing sequencing.
