Abstract
The present invention relates to a method for sharing a medium access control address on an elastic grouping ring network interface, which belongs to the technical field of a computer network. Firstly, RPR control respectively sends initialization messages to two medium access control of nodes so as to appoint the corresponding positions of both sides of A and B; media of the side A access control so as to receive the initialization messages and obtain an own MAC address from the side A, and the MAC address is sent to the RPR control; then the side A enters a normal operation state. Media of the side B access the control so as to receive the initialization messages and keep a non-operation state; after the RPR ring control receives the messages with the MAC address from the side A, the MAC address is preserved and is sent to the side B; after receiving the MAC address, the side B enters the normal operation state. The method of the present invention has the advantages of simple process and good realizability, and the present invention can uses the same MAC address at the side A and the side B of an RPR interface.
Description
Technical field
The present invention relates to a kind of method of on the Resilient Packet Ring network interface, sharing media access control address, belong to technical field of the computer network.
Background technology
A common RPR network (Resilient Packet Ring, hereinafter to be referred as the RPR looped network) logic diagram of interface is as shown in Figure 1, comprise a RPR control and two RPR media access control (Media Access Control, be designated hereinafter simply as MAC), these two MAC are called A side MAC and B side MAC.Wherein each MAC has MAC Address separately respectively, and the MAC Address of A side and B side is inconsistent.But as a rpr interface, MAC Address is the unique method for expressing of this node on looped network, if therefore different MAC Address is used in A, B both sides, can make other node on the looped network think that A, B both sides are on two different nodes by mistake, thereby cause the confusion of operating state, so require A side and B side to use same MAC Address.So just the problem of a MAC Address has appearred how sharing on two different MAC of a rpr interface.In the existing technology, RPR control directly is handed down to the AB both sides with a MAC Address that obtains from configuration order, and the AB both sides obtain to enter normal operating conditions after the MAC Address.Its shortcoming is, needs the MAC Address of manual configuration AB both sides, increased the complexity that rpr interface uses; Do not make full use of all MAC Address that have of AB both sides oneself, caused the waste of MAC Address.
Summary of the invention
The objective of the invention is to propose a kind of method of on the Resilient Packet Ring network interface, sharing media access control address, to solve the inconsistent problem of both sides MAC Address of RPR network, make the shared identical MAC Address of two MAC layers of whole rpr interface.
The method of sharing media access control address on the Resilient Packet Ring network interface that the present invention proposes comprises following each step:
1, a kind of method of sharing medium access control (MAC) address on Resilient Packet Ring (RPR) network interface is characterized in that this method comprises following each step:
(1) control of RPR looped network sends initial message to the MAC of RPR looped network interface both sides respectively.
(2) after the initialization, the MAC of RPR looped network interface one side sends to the control of RPR looped network with the MAC Address of oneself, enters normal operating conditions then;
(3) after described mac address information is received in the control of RPR looped network, this MAC Address is sent to opposite side MAC, this MAC enters normal operating conditions.
Described initial message is for specifying the relative position of both sides MAC on the RPR looped network interface.
Described opposite side MAC keeps non operating state receiving before the MAC Address that RPR looped network control issues.
The method of on the Resilient Packet Ring network interface, sharing media access control address that the present invention proposes, process is simple, realizability is good, can use same MAC Address in the both sides of rpr interface, thereby solved the sharing problem of MAC Address on the rpr interface effectively, guaranteed the uniformity of RPR internal system and external consistency.
Description of drawings
Fig. 1 is the building-block of logic of rpr interface in the prior art.
Fig. 2 is the building-block of logic that the rpr interface that proposes of the present invention is shared MAC.
Embodiment
As shown in Figure 2, the method of on the Resilient Packet Ring network interface, sharing media access control address that the present invention proposes, at first RPR control sends initial message to two medium access controls of node respectively, specify the relative position of the online both sides of Resilient Packet Ring, for example a side wherein is appointed as the A side, then opposite side is the B both sides.The relative position of A, B both sides can be specified arbitrarily.After the MAC of A side control receives initial message, obtain own MAC Address from this side, and MAC Address is sent to RPR control, the A side enters normal operating conditions then.After the MAC of B side receives initial message, keep non operating state.After the RPR ring is controlled the message of receiving from the A side that has MAC Address, preserve this MAC Address, and this MAC Address is sent to the B side.After the B side is received MAC Address, enter normal operating conditions.
Claims (2)
1, a kind of method of sharing medium access control (MAC) address on Resilient Packet Ring (RPR) network interface is characterized in that this method comprises following each step:
(1) control of RPR looped network sends initial message to the medium access control (MAC) of RPR looped network interface both sides respectively, and described initial message is for specifying the relative position of both sides MAC on the RPR looped network interface;
(2) after the initialization, a side of RPR looped network sends to the control of RPR looped network with the MAC Address of oneself, enters normal operating conditions then;
(3) after described mac address information is received in the control of RPR looped network ring, this MAC Address is sent to opposite side MAC, this MAC enters normal operating conditions.
2, the method for claim 1 is characterized in that wherein opposite side MAC receiving before the MAC Address that RPR looped network control issues, keeps non operating state.
