Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with the accompanying drawings and according to embodiment,
Technical scheme is described in detail.
Referring to Fig. 1, Fig. 1 is the website message processing method schematic flow sheet of MAC Address change in the embodiment of the present application.Tool
Body step is：
Step 101, during the MAC Address change of website, the website opens first timer.
Step 102, first timer then before, the website receive purpose website MAC Address be this website change
During the RPR data messages of the MAC Address after preceding or change, lower ring and lift-off processing are carried out to the RPR data messages.
After the application is in the MAC Address change of website, the MAC Address before the website is not changed directly is deleted,
But a timer is opened, the MAC Address before the timer then preceding safeguards the change, so that the topology of RPR rings is not more
Before new completion, lower ring can be normally carried out by remaining able to the RPR messages to purpose website MAC Address for the MAC Address before change
And lift-off processing, so as to ensure that the normal transmission of data message.
When implementing, the timing of the first timer can be configured according to practical application, such as be ensured
The topology of RPR rings updates can carry out normal process before completion to RPR data messages.
Step 103, in first timer to constantly, the website deletes the MAC Address before the change of this website.
In first timer to constantly, the website deletes the MAC Address before the change safeguarded.The first timer is while shadow
The processing that this website controls RPR message is rung, detailed process is as follows：
Referring to Fig. 2, Fig. 2 is that the website of MAC changes in the embodiment of the present application controls Message processing process to RPR.Specific step
Suddenly it is：
Step 201, website first timer then before, on RPR rings other websites send carry the website change
The RPR control messages of the MAC Address before MAC Address and change after change, so that other stations awares website on RPR rings
MAC Address changes, and the MAC Address before change and after change.
MAC Address after the site change controls the Source Site MAC Address field of message to carry by the RPR of transmission, becomes
MAC Address before change is carried by the custom field or reserved field in the RPR of transmission control messages.
Step 202, the website first timer then after, sent to the other websites on RPR rings and carry this website
The RPR control messages of MAC Address after change.
The website first timer then after, then to other websites send RPR control messages when, compared with realization, no
Need to carry the MAC Address before the change of this website.
If the website is as the unchanged website of MAC Address, the RPR controls that other websites are sent on RPR rings are received
It is handled as follows during message：
(1) if, the RPR control message carry send the RPR control message Source Site change after and change before MAC
The MAC Address after the Source Site changes is not present in address, and local topology database, there is the MAC before the change of the Source Site
Address, then control the topology information calculating network topology that message is carried, when the network topology calculated is with locally opening up according to the RPR
Flutter the Source Site of this in database change before the corresponding network topology of MAC Address it is identical when, then using the change of the Source Site after
MAC Address replace local topology database in the Source Site change before MAC Address；
Contents in table and the MAC Address pair before the change of the Source Site are set up for the MAC Address after the change of the Source Site
The contents in table identical RPR MAC address entries answered；And set up contents in table and the source for the MAC Address after the change of the Source Site
The corresponding contents in table identical RPR of MAC Address before the change of website integrates ring selection list item.
Meanwhile, the website integrates ring selection for the corresponding RPR MAC address entries of MAC Address and RPR before the change of the Source Site
List item sets second timer；Wherein, before the timing of second timer is more than the Source Site for the change of the Source Site
The timing for the timer that MAC Address is set；
Two timer then before, receive the corresponding RPR MAC address entries pair of the MAC Address before the change of the Source Site
During the message answered, the corresponding RPR MAC address entries of MAC Address not refreshed before the change of the Source Site；
In the second timer to constantly, the website deletes the corresponding RPR of MAC Address before the change of the Source Site
MAC address entries and RPR integrate ring selection list item.
(2) if, the RPR control message carry send the RPR control message Source Site change after and change before MAC
The MAC Address after the Source Site changes is not present in address, local topology database, with there is the MAC before the change of the Source Site
Location, then control the topology information calculating network topology that message is carried, when the network topology and local topology that calculate according to the RPR
When the corresponding network topology of MAC Address before the change of the Source Site of this in database is differed, RPR control messages are not handled, directly
To the local corresponding topology information of MAC Address being not present before change.
(3), the RPR control messages outside (1) and (2) two kinds of situations, are handled by existing realization.
Due to the renewal processing procedure of RPR MAC Address list item above, cause second timer then before, website may
There is the RPR MAC Address list items that corresponding two next-hops of destination address are differed, therefore, now receive purpose MAC
During the data message of address, it is handled as follows：
Website receives data message, and when determining that the data message need to carry out upper ring processing, if according to the data message
Target MAC (Media Access Control) address find two RPR MAC Address list items, then select purpose MAC in most newly-established RPR MAC address entries
The corresponding next hop address in address carries out RPR encapsulation and forwarded.
Below in conjunction with the accompanying drawings, after the MAC Address of any node changes on RPR rings in detailed description the application, each
The processing procedure of node.
The MAC Address change of website on RPR rings has a variety of situations, and the change such as artificially configured, the website is other
Standby equipment, the website are IRF equipment in system and main equipment and standby equipment in IRF equipment change.
Referring to Fig. 3, Fig. 3 is IRF division networking schematic diagrams in the application RPR networks.As shown in figure 3, the website on RPR rings
A is IRF equipment, and the IRF equipment is stacked and formed by device A 1 and device A 2, and device A 2 is that the member that election is main equipment sets
It is standby, device A 1 be do not elect be main equipment member device.Two logic interfacings of the IRF equipment (website A) on RPR rings exist
In device A 1.
During IRF equipment normal works, website A MAC Address is the MAC Address (00E0-0000- of main equipment (device A 2)
00A0)。
If a certain moment, IRF equipment divides, device A 1 is only existed in the new IRF equipment where device A 1, because
This, device A 1 is elected as main equipment, then website A MAC Address becomes the MAC Address 00E0-0000-00A1 for turning to device A 1
If (there is multiple equipment in the IRF where device A 1, the MAC for the equipment for being main equipment will be elected in this multiple equipment
Location as website A MAC Address).Therefore, website A MAC Address changes, and the MAC Address before change is 00E0-0000-
00A0, the MAC Address after change is 00E0-0000-00A1.
Now, website A opens a timer, configures timing by concrete application, is such as set to 3 seconds, in this 3 seconds,
When website A receives the RPR data messages that purpose website MAC Address is 00E0-0000-00A0 or 00E0-0000-00A1, stand
Point A carries out lower ring and lift-off processing to the RPR data messages.
It is timed to constantly in this timer, website A deletes the MAC Address before the change of maintenance, can also identify this
MAC Address before change is not the MAC Address of this equipment；Receive the RPR that purpose website MAC Address is 00E0-0000-00A0
Data message is handled by existing realization.
The application is when implementing, when website A MAC Address changes, and other equipment may not felt also on ring
Know, this retains the MAC Address before change using a period of time, it is the MAC before change that can make point of destination point MAC Address
Location 00E0-0000-00A0 message still can correctly perform lower ring and lift-off processing.
After website A MAC Address changes, can with the MAC Address 00E0-0000-00A1 after changing on ring other
Website sends RPR control messages, for example, TC (Topology Checksum, topology verification and) message, TP (Topology
Protection, topology protection) message, ATD (Attribute Discovery, Attribute Discovery) message, i.e., RPR control report
MAC Address 00E0-0000-00A1 after the Source Site MAC fields filling change of text, while carrying one in RPR control messages
MAC Address 00E0-0000-00A0 before mark and change, i.e., control reserved field or the custom field filling of message in RPR
MAC Address 00E0-0000-00A0 before change, so as to receive stations aware website A on the ring of these RPR control messages
MAC Address is changed, and knows the MAC Address before change and after change.
Website A, to constantly, is sent in timer with the MAC Address 00E0-0000-00A1 after change to other equipment on ring
When RPR controls message, the MAC Address 00E0-0000-00A0 before change is no longer carried.
Other websites receive the MAC Address 00E0-0000- before the change that website A is carried while website A is sent on ring
During the 00A0 and MAC Address 00E0-0000-00A1 after change RPR control messages, it is handled as follows and (enters by taking website D as an example
Row explanation)：
(1), website D determines to be not present in local topology database after the change for the website A that the RPR controls message to carry
MAC Address 00E0-0000-00A1, and there is the MAC Address 00E0-0000- before RPR control message carrying websites A change
During 00A0, according to the RPR control message carry topology information calculating network topology, when the network topology calculated with local
When the corresponding network topologies of MAC Address 00E0-0000-00A0 in topological database before website A change are identical, it is determined that should
RPR controls message to be that the MAC Address before changing sends for 00E0-0000-00A0 website A, then by local topology data
MAC Address 00E0-0000-00A0 in storehouse is revised as 00E0-0000-00A1.
In this case, website D needs processing RPR to integrate ring selection table and RPR after topological database has been updated, also
Mac address table.
Website D sets up 00E0- in the RPR MAC Address list items that next hop address is 00E0-0000-00A1, the list item
The corresponding other guides of 0000-00A1 replicate the corresponding content of list item that next-hop mac address is 00E0-0000-00A0.
Referring to table 1, table 1 is the content that the RPR MAC Address list items that next hop address is 00E0-0000-00A0 are included.
Referring to table 2, table 2 is the content that the RPR MAC Address list items that next hop address is 00E0-0000-00A1 are included.
| MAC Address | Next-hop |

Table 1
| MAC Address | Next-hop |
| 0000-0000-0002 | 00E0-0000-00A1 |
Table 2
From Tables 1 and 2, table 2 is equivalent to the content for replicating a table 1, and by the next-hop 00E0-0000- in table 1
00A0 is revised as after 00E0-0000-00A1, is used as the content of table 2.
The letter that VLAN ID, status, TTL etc. need to record can also be included in existing realization in RPR mac address tables
Breath, the application is when implementing, to this and without modification, and related content present in list item is replicated.
After the completion of the foundation of table 2, ageing time can be set to table 1, and (as set timer, the timing of timer is
For ageing time), time of the ageing time slightly larger than the timer opened on website A of setting, arrived in the ageing time
Shi Qian, website D are not carried out when receiving the data message that source MAC is 0000-0000-0002 to the list item shown in table 1
Refresh；In the ageing time to constantly, website D deletes the list item shown in table 1.For newly-established table 2, by real in existing realization
It is existing, ageing time is such as set, refreshes ageing time.
Website D is that MAC Address 00E0-0000-00A1 sets up RPR synthesis ring selection list items, the 00E0- in the list item of foundation
The RPR that the corresponding contents of 0000-00A1 replicate MAC Address 00E0-0000-00A1 integrates corresponding content in ring selection list item.
Referring to table 3, table 3 integrates the corresponding content of ring selection table for MAC Address 00E0-0000-00A0 RPR.
Referring to table 4, table 4 integrates the corresponding content of ring selection table for MAC Address 00E0-0000-00A1 RPR.
| MAC Address | Ring number |
| 00E0-0000-00A0 | 0 |
Table 3
| MAC Address | Ring number |
| 00E0-0000-00A1 | 0 |
Table 4
From table 3 and table 4, table 4 is equivalent to the content for replicating a table 3, and by the MAC Address 00E0- in table 3
0000-00A0 is revised as after 00E0-0000-00A1, is used as the content of table 4.
RPR, which is integrated, in existing realization can also include the information that TTL, TYPE, device identification etc. need to record in ring selection table,
The application is when implementing, to this and without modification, and related content present in list item is replicated.
It is that table 3 sets ageing time (such as to set timer, the timing of timer is old after the completion of the foundation of table 4
The change time), the ageing time of setting is identical with the ageing time set for table 1, when ageing time then, delete table 3 institute
The list item shown；Table 4 can integrate the ageing time of ring selection table compared with setting RPR is realized, with the ageing time of table 2.
When implementing, RPR can also be integrated ring selection list item and merge realization with RPR MAC Address list items,
Together handled, be not detailed herein.
(2), website D determines to be not present in local topology database after the change for the website A that the RPR controls message to carry
MAC Address 00E0-0000-00A1, and there is the MAC Address 00E0-0000- before RPR control message carrying websites A change
During 00A0, according to the RPR control message carry topology information calculating network topology, when the network topology calculated with local
When the corresponding network topologies of MAC Address 00E0-0000-00A0 in topological database before website A change are different, this is not handled
RPR controls message.
(3), website D determines exist in local topology database after the website A change that the RPR controls message carrying
(no matter whether RPR control messages also carry other MAC Address to MAC Address 00E0-0000-00A1, before such as website A change
MAC Address), by existing realization handle, according to the control message carry topology information calculating network topology, and determine calculate
Whether the network topology gone out network topology corresponding with the MAC Address of this in local topology database 00E0-0000-00A1 is identical,
If it is, maintaining the corresponding network topologies of MAC Address 00E0-0000-00A1 in local topology database constant；Otherwise, make
MAC Address 00E0-0000-00A1 map networks topology in local topology database is updated with the network topology calculated.
(4), website D is when receiving other RPR control messages, compared with realization, according to message content determine whether into

Realization is handled；If finding correspondence list item, handled according to contents in table：
When the outgoing interface in the MAC forwarding-table items found is local port, then the message is passed through into the port that finds
Forwarding；If the outgoing interface found is RPR logic interfaces, illustrate that this data message needs to perform upper ring processing on website D.
Second step, when data message needs to carry out upper ring processing, need to find the target MAC (Media Access Control) address correspondence of the data message
Next hop address encapsulate the data message for RPR data messages；And know by being sent out with which logic interface that the RPR is bound
Send, i.e., sent by outer shroud or inner ring.
Website D is according to the target MAC (Media Access Control) address 0000-0000-0002 of the data message in local RPRMAC address tables
Search, when finding a correspondence MAC Address list item, according to corresponding next-hop in the RPRMAC address list items to the data
Message carries out the encapsulation of RPR；
And hair is found in RPR integrates ring selection table according to the target MAC (Media Access Control) address 0000-0000-0002 of the data message
Give the RPR ring numbers of the data message, and the data message of encapsulation RPR is passed through on the corresponding ring of RPR ring numbers that finds
The port for sending message is sent.
When being searched in RPR mac address tables, if finding next in two correspondence list items, most newly-established list item
Address is jumped, that is, the MAC Address after changing carries out RPR encapsulation., can will be newly-established and originally set up when implementing
This two list item mark-ons are known, and are the MAC Address after change to distinguish the corresponding next hop address of which list item.
3rd step, the purpose website MAC Address that website B receives website D transmissions is 00E0-0000-00A1 or 00E0-
