It crosses RPR ring to turn, then can send a service request to rpr interface plate and request for the PP into rpr interface plate as Ethernet
Data message distributes RPR physical rings, and the RPR node device of one reception Ethernet data message of distribution, the RPR node are set
Standby distribution can be determined based on the business information carried in service request.Ethernet data message can be to be multiple
Multiple data messages that one user terminal is sent simultaneously, the multiple data messages for being also possible to a plurality of clients while sending.
S302, according to receive Ethernet data message port information and RPR virtual ring division rule predetermined,
Determine the corresponding RPR virtual ring of port information.
In RPR virtual ring division rule predetermined, the corresponding relationship of port information Yu RPR virtual ring is defined, i.e.,
Which port is divided into same RPR virtual ring.In this way, can determine this according to the port information for receiving Ethernet data message
The corresponding RPR virtual ring of port information.
S303, search Ethernet data message the corresponding RPR MAC Address of target MAC (Media Access Control) address and RPR virtual ring on
RPR forwarding table corresponding with RPR MAC Address.
The target MAC (Media Access Control) address of the data message is carried in data message, target MAC (Media Access Control) address is ether netting index in Ethernet
According to the address information for the purpose user terminal that message needs to be forwarded to, the target MAC (Media Access Control) address is corresponding with RPR MAC Address, RPR
MAC Address is the mac address information for the RPR node device that data message needs lower ring, that is, corresponds to data message from which RPR
Ring under node device can reach purpose user terminal.
It can be true according to optimal ring selection strategy (such as the shortest RPR ring in selection path, selection the smallest RPR ring of flow etc.)
Surely by 0 ring or 1 ring forwarding data packets to RPR MAC Address, ring selection result determines the next of data message forwarding
RPR node device.Each RPR virtual ring is equivalent to independent RPR ring, and therefore, each RPR virtual ring has independent
RPR forwarding table, record has forwarding relevant information, such as target MAC (Media Access Control) address, RPR MAC Address etc. in RPR forwarding table.
Ethernet data message is encapsulated as RPR data message according to RPR MAC Address by S304.
In RPR virtual ring, data message is forwarded with RPR format, in addition to including Ethernet data report in RPR data message
It should also include RPR MAC Address other than text, that is, the data message final RPR node device that needs to be forwarded to
MAC Address, to guarantee that data message can be accurately forwarded to purpose user terminal.Since each RPR virtual ring is equivalent to independence
RPR ring, therefore, each RPR virtual ring carry out data message encapsulation/decapsulation be independent from each other.
Optionally, S304 is specifically as follows:
Ethernet data message is sealed according to RPR virtual ring corresponding priority mapping rule according to RPR MAC Address
Dress is RPR data message corresponding with the priority of Ethernet data message.
Since each RPR virtual ring is equivalent to independent RPR ring, each RPR virtual ring has independent excellent
First grade mapping ruler.Each data message has different priority, and the higher message of priority can be forwarded preferentially, and ether
The priority of network data message is corresponding with the priority of RPR data message, i.e. the priority of Ethernet data message is higher, right
Its priority for encapsulating obtained RPR data message is also higher, and the priority mapping rule of each RPR virtual ring is mutually indepedent.
Optionally, S304 is specifically as follows:
According to RPR MAC Address, Ethernet data message is encapsulated, and empty in the specified reserved place of specific field record RPR
The ring of near-ring identifies, and obtains RPR data message.
Most of RPR node device after receiving RPR data message, be merely able to identify the RPR data message from which
A RPR node device forwards, the RPR data message is needed from the information such as ring under which RPR node, and can not identify this
RPR data message is the data message of which RPR virtual ring, needs to identify forwarding RPR data message again by the above method
RPR virtual ring, in this way, forwarding rate can be seriously affected, therefore, in order to guarantee that other RPR node devices can distinguish RPR number
It is the data message of which RPR virtual ring according to message, improves forwarding rate, needs to carry RPR virtual ring in RPR data message
Ring mark.
Comprising an extended control (extension control) field in RPR data message, for providing RPR datagram
The data description of text, as shown in figure 4, extended control field includes 8 altogether, wherein ef accounts for 1, is used to indicate this
Whether RPR data message is amplifying message；Fi accounts for 2, is used to indicate whether the RPR data message is broadcasting packet；Ps accounts for 1
Whether position is used to indicate the RPR data message for the second time by source RPR node device；So accounts for 1, is used to indicate the RPR data
Whether message is sequence message；Res is reserved place, accounts for 3, since res is reserved place, can identify the RPR by extending res
Which RPR virtual ring data message belongs to, and after RPR node device receives RPR data message, is determined according to res by this RPR number
Corresponding RPR virtual ring processing logic, which is sent to, according to message is forwarded processing.
Certainly, the ring mark of RPR virtual ring is not limited only to carry in extended control field, can also utilize
The reserved place of other fields is carried.
S305 forwards RPR data message according to the exit port of RPR MAC Address in RPR forwarding table.
After determining RPR virtual ring, logic is handled into corresponding RPR virtual ring, due to being stored in RPR forwarding table
RPR MAC Address, what the exit port of the RPR MAC Address determined forwarding RPR data message is the east orientation end of RPR node device
Mouth is western to port.Also, the type of data message also determine RPR node device to the mode of operation of RPR data message,
For example, in each intermediate node of data message approach, then passing through east orientation port or west if data message is unicast message
Ring operation was executed to RPR data message to port；If data message is broadcasting packet, pass through east orientation port or west to end
While mouth executed ring operation to RPR data message, lower ring operation is executed to RPR data message.
When ring under carrying out RPR data message operates, can be determined based on the RPR virtual ring of forwarding RPR data message
The service logic mouth of Ethernet data message after sending RPR data message decompression on RPR node device, from business logic interface
It in trunk group, optionally selects a port and sends datagram, ring determines RPR virtual ring in the process and Ethernet data message
Process it is exactly the opposite, I will not elaborate.
