Problems solved by technology

The flows flowing through the network are considered independent of each other and processed separately. The separate processing of the flows requires frequent changes in the route of the flow table in the network, making the network highly unstable and busy with transmission and processing of connection request signaling.

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] Programmable exchange system structure of the present invention is as attached figure 1 shown. The programmable switch system consists of multiple bypass units and multiple processing units, and also includes standard interfaces with the virtual layer, division of channels, and so on. Among them, the bypass unit is used to establish logical links between non-adjacent nodes; the channel is used to divide each physical link into multiple channels (such as optical paths) to meet the different requirements for bandwidth or QoS between processing units ; The virtual machine in the processing unit is used for forwarding, processing, computing and caching of data packets, and its right-angle exchange provides basic switching functions for the processing unit; the standard interface is used to program the programmable switch through the virtual layer. Programmable ite...

Abstract

The invention provides a programmable switchboard system applicable to the future internet, which is used for building a structured network, achieving simple transmission mechanism and complex network functions, and enabling the network architecture to be provided with programmable and virtualized characteristics. Each programmable switchboard is divided into a plurality of bypass units and logic processing units and provided with certain transmission functions and programmable ports. The bypass units are used for building a logic link between non-adjacent processing units for meeting requirements of building a structured network topology and achieving low latency and high speed transmission performance, the processing units are used for programming and achieving complex node functions such as transmitting, processing, calculating and buffer memory, a right angle switch function customized for the structured network is used for achieving shortcut switch, safe route and multicast, and the programmable port provides programming and virtualized management of a bypass mode, the link rate, a switch mechanism and functions of the processing units.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a design technology of a programmable switch system suitable for the future Internet. technical background [0002] The goal of the future Internet is to create a brand-new architecture suitable for the rapid development of future Internet services. In the research of architecture, new network architecture schemes centered on information, centered on service, and centered on users have appeared, and programmable and virtualization have become the technical characteristics of these new network architecture schemes. [0003] In the network architecture of ICN (Information-centric Future Internet), different from the traditional network node technology, nodes are endowed with the function of caching content. The content requested by the user is cached in the nodes along the way during transmission, so that other users can obtain the content from nearby nodes, so as to ...
