Abstract

The invention relates to a method for sharing a medium access control address on an elastic packet ring network interface, which belongs to the technical field of computer networks. In this method, the RPR control sends initialization messages to the two media access control nodes of the node respectively, specifying the relative positions of A and B sides; after receiving the initial message, the media access control on the A side obtains its own MAC address, and send this MAC address to the RPR control, and then the A side enters the normal working state; after receiving the initialization message, the media access control on the B side remains in the non-working state; the RPR ring control receives the MAC address from the A side. After receiving the message of the address, save the MAC address and send the MAC to the B side; after receiving the MAC address, the B side enters the normal working state. The method of the invention has simple process and good realizability, and the same MAC address can be used on the A side and the B side of the RPR interface.

Description

A Method for Sharing Media Access Control Addresses on Resilient Packet Ring Network Interfaces

technical field

The invention relates to a method for sharing a medium access control address on an elastic packet ring network interface, which belongs to the technical field of computer networks.

Background technique

Usually a logical block diagram of a resilient packet ring network (Resilient Packet Ring, hereinafter referred to as RPR ring network) interface is shown in Figure 1, including one RPR control and two RPR media access controls (Media Access Control, hereinafter referred to as MAC), The two MACs are called A-side MAC and B-side MAC respectively. Each MAC has its own MAC address, and the MAC addresses of side A and side B are inconsistent. However, as an RPR interface, the MAC address is the only representation method of this node on the ring network. Therefore, if A and B use different MAC addresses, other nodes on the ring network will mistakenly believe that A and B are on two different nodes, which leads to confusion in the working state, so the A side and the B side are required to use the same MAC address. In this way, the problem of how to share a MAC address on two different MACs of an RPR interface arises. In the existing technology, the RPR control directly sends a MAC address obtained from a configuration command to both sides of AB, and both sides of AB enter into a normal working state after obtaining the MAC address. The disadvantage is that the MAC addresses on both sides of AB need to be manually configured, which increases the complexity of using the RPR interface; the MAC addresses owned by both sides of AB are not fully utilized, resulting in a waste of MAC addresses.

Contents of the invention

The purpose of the present invention is to propose a method for sharing the media access control address on the elastic packet ring network interface, to solve the problem of inconsistent MAC addresses on both sides of the elastic packet ring network, so that the two MAC layers of the entire RPR interface share one same MAC address.

The method for sharing the media access control address on the elastic packet ring network interface proposed by the present invention includes the following steps:

1. A method for sharing a medium access control (MAC) address on a resilient packet ring (RPR) network interface, characterized in that the method comprises the following steps:

(1) The RPR ring network control sends initialization messages to the MACs on both sides of the RPR ring network interface.

(2) After initialization, the MAC on the side of the RPR ring network interface sends its own MAC address to the RPR ring network control, and then enters the normal working state;

(3) After receiving the MAC address information, the RPR ring network controller sends the MAC address to the MAC on the other side, and the MAC enters a normal working state.

The initialization message specifies the relative positions of the MACs on both sides of the RPR ring network interface.

The MAC on the other side remains in a non-working state before receiving the MAC address issued by the RPR ring network control.

The method for sharing the media access control address on the RPR interface proposed by the present invention is simple in process and good in realizability, and can use the same MAC address on both sides of the RPR interface, thus effectively solving the problem of an RPR interface. The sharing of MAC addresses ensures the internal and external consistency of the RPR system.

Detailed ways

As shown in Figure 2, in the method for sharing the MAC address on the RPR network interface proposed by the present invention, first, the RPR control sends initialization messages to the two MACs of the node respectively, specifying the two sides of the RPR network For example, if one side is designated as side A, the other side is the two sides of B. The relative positions on both sides of A and B can be specified arbitrarily. After receiving the initialization message, the MAC controller on the A side obtains its own MAC address from the local side, and sends the MAC address to the RPR controller, and then the A side enters the normal working state. After receiving the initialization message, the MAC on side B remains in a non-working state. After the RPR ring control receives the message with the MAC address from side A, it saves the MAC address and sends the MAC address to side B. After receiving the MAC address, side B enters the normal working state.
