Problems solved by technology

However, the current ARP protocol can only provide a simple conversion function from IP address to MAC address, and cannot provide the load sharing function of the link layer, which must be implemented by the application program.
The application program realizes the load sharing between multiple network ports. According to the ARP protocol, each interface of the processing line card is required to have a separate IP and MAC, so that the application program must constantly change when sending a message. Destination IP address, very inconvenient to implement

Embodiment Construction

[0022] The hardware address resolution method and communication processing equipment of the present invention mainly include the following two aspects:

[0023] Implement hardware address resolution in the internal user plane through non-broadcasting, and establish a resolution table from IP address to MAC address;

[0024] In the link layer, the protocol handles the load sharing algorithm between multiple network ports on the line card, which is suitable for high-traffic services.

[0025] In the hardware address resolution method and the communication processing device of the present invention, the hardware address resolution module on the switching line card processes the IP address and the MAC address of the line card according to the protocol, generates all hardware address resolution table entries centrally, and transmits the The hardware address resolution table entry is synchronized to all protocol processing line cards. After receiving the multicast message, the proto...

Abstract

In this invention, the hardware address analysis method is applied to the inside user interface of communication device, generates the hardware address analysis item for all protocol process cards according to card IP and MAC addresses, and synchronizes all the cards by said analysis item. It applies non-broadcast hardware address analysis method, prohibits the message entering in the inside user interface to avoid broadcast storm, can converse IP address into MAC address reliably and accurately, and convenient to top application program.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a hardware address resolution method capable of avoiding broadcast storms and supporting a load sharing algorithm. Background technique [0002] For a general server or client, when sending an IP message in Ethernet, we usually use the address translation protocol (ARP) to obtain the Ethernet address (MAC) corresponding to the destination IP in the message, and then encapsulate it into an Ethernet frame. The ARP protocol is implemented based on the broadcast method. When the host sends a message out, it first checks whether there is a MAC address corresponding to the destination IP in the cache. If not, it will broadcast an ARP request message to all hosts in the subnet. . After the host receives this ARP message, if it finds that the destination IP in the request message is itself, it will return its own MAC address to the requester. [0003] The shortcoming of t...
