Technical Field

The invention relates to the technical field of ARP data packets of an IASS network platform, in particular to an optimization method and an optimization system for processing ARP data packets under the IASS network platform.

Background

With the development of the internet, cloud computing is also becoming more and more a trend. For a traditional cloud computing IASS service, the transmission of the network thereof is required to follow the network transmission protocol. Under the TCP/IP network architecture, the conversion of the IP address and the MAC address needs to use an ARP protocol. The traditional network architecture is a network situation under a physical device, wherein the traditional network architecture is as follows: the router is connected with the switch through the gateway, and the switch can be connected with a plurality of PC terminals. Under the traditional network architecture, the method has the following characteristics: 1. the device sends out broadcast packets (flooding the network link) continuously and periodically; 2. then the device receiving the broadcast unicasts (replies the data packet) if the device requests the device, and directly discards the data packet if the device does not request the device; 3. the ARP request packet, whether needed or not, is sent to the outside in the default 5 minutes (since the corresponding entry of the ARP table information is deleted by default for this period, it is sent to the outside).

The broadcast packet of the ARP request is always filled on a network link, and the birth of the protocol is the flow, so that with the development of cloud computing, more clients exist in a local area network in a virtual environment, and more network devices exist. Causing broadcast packets of ARP requests to ramp up. The method occupies part of network bandwidth, and simultaneously, broadcast packets can be captured during packet capture analysis, which affects analysis efficiency.

For a traditional ias service platform, virtualization is performed under a traditional network architecture, that is: the virtual router is connected with the virtual switch through the gateway, and the virtual switch can be connected with a plurality of virtual machines or virtual servers.
