Embodiment

[0043] The present invention provides a large-scale local area network content collaboration method, which replaces the existing technology of providing content services with the application layer with the two-layer data link layer technology, so as to shorten the service processing time and deliver the content in time. The Layer 2 device used in the following embodiments is a switch.

[0044] In order to achieve the purpose of the above invention, a large-scale local area network content collaboration method of the present invention includes: cache node discovery, data discovery, collaborative data cache and data service methods. The method involves the following entities: a switch and a host. In the present invention, the switches can be physical entities such as Ethernet metropolitan switches, Ethernet access switches, wireless APs (access points); the hosts can be physical entities such as servers, PCs, mobile phones, and PDAs. In the present invention, the switch has rel...

Abstract

The invention discloses a content providing method and system for a large local area network based on two-layer link layer equipment. The method comprises the following steps of discovering the rest of two-layer link layer equipment based on the two-layer link layer equipment and taking the rest of the discovered two-layer link layer equipment as cache nodes of the two-layer link layer equipment; sending a data request to the cache nodes discovered by the two-layer link layer equipment based on one two-layer link layer equipment through a multicast or unicast way; and when the two-layer link layer equipment receives a data request frame of a host, checking local data storage, if data exists, sending the data to the host in a form of data frames, otherwise checking a data cache mapping table of the two-layer link layer equipment, finding the cache node stored with the data, if the cache node and the host are arranged in the same Ethernet segment, redirecting the host to the cache node, and providing data services for the host through the cache node.

Description

technical field [0001] The invention relates to the field of network technology, in particular to data service and sharing in a large local area network. Background technique [0002] Since the birth of DARPANET in the late 1960s, researchers began to explore the method of network information sharing; in the early 1980s, with the help of the Berkeley BSD operating system, the TCP / IP protocol stack became the de facto protocol standard of the Internet. In the 1990s, the emergence and rapid spread of the World Wide Web set off an upsurge in content sharing; at the beginning of the 21st century, P2P ( Peer-to-peer) applications have had a severe impact on traditional CDNs (Content Delivery Networks). Nowadays, from computers to PDAs to mobile phones, almost all kinds of P2P sharing software can be found. Among these software, video sharing is one of the main applications. [0003] Whether it is early content sharing or content sharing in the 21st century, there are two basic...
