Embodiment Construction

[0051] The present invention proposes an ARP proxy method for the same network segment with a specific address, maintains a global proxy ARP address list, and also requires maintaining an ARP local address list on each external interface that runs the ARP protocol, and saves the ARP proxy on this interface. Address, the interface address of this interface can also be saved during implementation.

[0052] Regularly check whether all proxy IPs in the global proxy ARP address list are valid, and global refers to the entire device or system. The global proxy ARP address list saves all proxied IPs including invalid IPs, and the ARP local address list only saves valid IPs of this interface.

[0053] Same network segment ARP proxy method of the present invention comprises the steps:

[0054] Step 110, set up a list of global proxy ARP addresses, save the currently configured IP addresses to perform ARP proxy on the same network segment, maintain an ARP local address list on each int...

Abstract

The invention provides a communication process among internal processing panels. A mobile communication system comprises several network elements which respectively comprise an internal processing panel and an interface panel, wherein the network elements are mutually connected through the interface panels. The communication among the internal processing panels of different network elements comprises the following steps that choosing a transferring interface for the internal processing panel to communicate with the external portion, allocating an interface address, building up a virtual interface on the internal processing panel and allocating a virtual address which is located in the same network section with the interface address of the transferring interface, establishing a address resolution protocol ARP local address list on the transferring interface, adding the virtual address of the internal processing panel which is transferred by the transferring interface in the list, and conducting the communications among the internal processing panels through the ARP agency of the transferring interface. The invention further provides an ARP processing process in the same network section.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for performing address resolution protocol (ARP) proxy on the same network segment IP (Internet Protocol) and a communication method between internal processing boards. Background technique [0002] When the IP data packet is transmitted through the Ethernet, the destination IP address needs to be converted into the destination link layer address, and this conversion is completed through the Address Resolution Protocol (ARP). Its main working method is that the local end sends an ARP request message containing the destination IP address, and the peer end responds with an ARP response message containing its own link layer address after receiving it, and the local end combines the destination IP address with the link layer address. One-to-one correspondence is stored in the ARP cache table. When the subsequent data packets are sent, the ARP cache table can b...
