Abstract

The disclosure relates to an ARP table management method, a processor core, a storage medium, and an electronic device. The method is applied to the only writing processor core capable of writing the ARP table in the multi-core processor, and the method includes: when receiving an ARP response, establishing a new ARP in the ARP table according to the ARP response entry, the ARP response is used to respond to the ARP request broadcast by any processor core in the multi-core processor core; determine whether the ARP response is the response to the ARP request sent by the write processor core; if the The ARP response is the response to the ARP request sent by the write processor core, then send the cached ARP message to the destination according to the physical address in the newly established ARP entry; if the ARP response is not the write processor core In response to the sent ARP request, all other processor cores in the multi-core processor are notified that the ARP table is updated.

Description

technical field [0001] The present disclosure relates to the computer field, and in particular, relates to an ARP table management method, a processor core, a storage medium, and an electronic device. Background technique [0002] ARP (Address Resolution Protocol, Address Resolution Protocol) is a TCP / IP protocol for obtaining a physical address based on an IP address. Before the host sends a packet, it broadcasts the ARP request containing the target IP address to all other hosts on the network, and receives the return message to determine the physical address of the target. After receiving the return message, the IP address and physical address are stored in the machine The ARP table is reserved for a certain period of time, and the ARP table is directly queried before the next contract to save resources. [0003] The ARP table is a packet operation resource, that is, the ARP table needs to be queried before sending a packet. In an asynchronous multi-core processor, the ...
