Rings based high capacity expandable packet switching network arrangement

Abstract

The invention discloses a large capacity and expandable grouping exchange network structure, which adopts three level structure, wherein a first level is a flow distribution level, a second level is a transfer level consisting of a plurality of separated loop network, and a third level is a transaction flow convergence level. The structure can fully utilize the middle level loop network to accomplish multicast, and provides a good network property and expansion capacity, so as to be suitable for serving as an exchange network for the grouping internet core router.

Description

Technical field: [0001] The invention relates to the technical field of communication, in particular to a large-capacity scalable packet switching network structure based on rings, which is used to construct Internet T-bit core routers. Background technique: [0002] At present, with the rapid growth of the number of Internet users and the number of sites in the world, the demand for network bandwidth has increased sharply, and users have also put forward higher requirements for Internet service quality and service content. Therefore, the design of Internet core routers is proposed. new challenge. Due to the development of optical communication technology, the transmission bandwidth resources are multiplied, which can meet the requirements of the network for bandwidth growth. However, because the growth rate of network switching capacity is far lower than the growth rate of bandwidth, Terabit Router (TSR), as a solution for building a high-performance information network, h...
