Embodiment 1
A method of overcoming RRPP fringe node flow interrupt, the corresponding edge port of smallest subring in looped network is selected to put
It opens, specifically includes the following steps:
Step 1, RRPP are a kind of agreements of layout type, are matched using RRPP agreement to every interchanger in networking
It sets.In the present embodiment: network environment is 6 H3C S58 series of switch.One main ring is set in networking, and two subrings are such as schemed
Shown in 1.DeviceA~DeviceF constitutes RRPP domain 1, and configuration main control VLAN is set as VLAN 100, and protection VLAN is set as VLAN
200to 300.Main ring includes equipment A, B, C, D, and subring 1 includes equipment B, D, E, and subring 2 includes equipment B, D, F.Configure main ring
Host node be equipment A and designated equipment A major-minor port.The transmission node of main ring and the edge port of subring are equipment B.It is main
The transmission node of ring and the assistant edge node of subring are equipment D.The host node of subring 1 and 2 is respectively equipment E and F, specified to set
The major-minor port of standby E and F.The port that edge port and assistant edge port only access subring is set as edge port.
Step 2, when primary link is all broken between Edge node and assistant edge node, select smallest subring in 2 subrings
Edge port decontrol.For the case where there are two subrings in RRPP network topology, there are two common nodes for each ring, and the two
Common node is identical.The number self-defining of subring, is generally incremented by since 2.Subring is stored in certainly from small to large by ring number
In the chained list of definition.When fringe node has received Major-Fault message, it was demonstrated that main ring link breaks down, fringe node
Edge port is blocked, and at this moment the edge port of smallest subring can be selected to decontrol in chained list.It neither will lead to 8 words cyclization,
" isolated island " will not be formed.The flow chart such as Fig. 2 for selecting smallest subring to decontrol.
Step 3, when subring a certain in networking be deleted, if fringe node has selected for the edge port of smallest subring
It decontrols.And failure has occurred in certain link for connecting edge port at this time.Whether it is to decontrol that at this moment fringe node can perceive
That link failure has occurred, if it is not, then keep current state without modification.If it is, need to be in remaining health
The edge port that a smallest subring is reselected in subring is decontroled, and flow chart is as shown in Figure 3.
When there is subring increase in networking, in the case where chained list non-empty, in order to reduce the processing load of CPU, block immediately,
Other processing are not done.Selection smallest subring need not be thus traversed again.If current chained list is sky, newly-increased subring is decontroled
Edge port, the following Fig. 4 of flow chart.
It selects the corresponding edge port of smallest subring in looped network to decontrol methods experiment interpretation of result, passes through the life of VTP tool
Enable row display as can be seen that the edge port XGE2/0/3, XGE2/0/4 of fringe node the port status whole by
Obstruction, the edge port XGE2/0/3 for becoming smallest subring are decontroled, and the edge port XGE2/0/4 obstruction of non-minimum subring is such as schemed
Shown in 5.It is consistent to check that the bottom state of interface and platform are got.
The XGE2/0/5 mouth of 3 mouthfuls of tester connection equipment B beats stream, and equipment C, D, E, F are also separately connected a tester and make
For the exit port of flow, (3 ports are the head piece of beating of tester in lower Fig. 6, and 4 ports are flow exit port, only acquire equipment here
D exit port packet receiving number, other three outlet lip reflexes are consistent with this).When a primary link is broken, flow can be rapidly switched to
Another chain road.When two primary links are all broken, edge port is all blocked, and fringe node forms " isolated island ", some
Time point tester send and receive packets number screenshot, such as Fig. 6.After the present invention, the corresponding edge port of smallest subring is released, some
Time point tester send and receive packets number screenshot, as shown in Figure 7.
Fig. 8,9 are the packet sending and receiving samples acquired in different time points, and horizontal axis is the tester for connecting fringe node in figure
It beats head piece message and sends number, the tester exit port that the longitudinal axis is connecting node D receives message number, and edge port is all blocked
When, exit port packet receiving number is very few, passes through almost without flow, such as Fig. 8.After the present invention, exit port packet receiving number and beat
Head piece is given out a contract for a project several almost the same, and flow is not blocked, and such as Fig. 9, demonstrates feasibility of the invention.
