Active networks represent a quantum step in the evolution of packet - switched network by providing a programmable network interface in network nodes 主動(dòng)式網(wǎng)絡(luò)技術(shù)提出了可編程的網(wǎng)絡(luò)體系結(jié)構(gòu)的思想,標(biāo)志著分組交換網(wǎng)絡(luò)設(shè)計(jì)思想的飛躍。
In this paper , we propose a novel approach - ip virtual switches ( ipvsw ) . ipvsw is a programmable network architecture that consists of dynamic virtual switches supporting multi - services in the ip traffic network 本文介紹了一種多服務(wù)網(wǎng)絡(luò)的技術(shù)途徑? ? ip虛擬交換機(jī), ip虛擬交換機(jī)是一種支持動(dòng)態(tài)可編程的多ip服務(wù)流的體系結(jié)構(gòu)。
The " active " of active networks exhibit in two aspects : firstly , the resources of active network node are highly abstracted to a programmable network application programming interface . with this interface , the functionality of network nodes can be dynamically constructed and refined , and it could provide the more rich process capability with the packets . on the other hand , some executable programs are carried in user packets , which can execute in network nodes and change the network ' s behaviors as seen by user 主動(dòng)式網(wǎng)絡(luò)的“主動(dòng)性”表現(xiàn)在兩個(gè)方面:首先,在主動(dòng)式網(wǎng)絡(luò)中,結(jié)點(diǎn)資源(包括計(jì)算處理,緩存以及傳輸資源)被高度抽象為一種可編程的網(wǎng)絡(luò)應(yīng)用編程接口,通過這一網(wǎng)絡(luò)應(yīng)用編程接口,網(wǎng)絡(luò)結(jié)點(diǎn)所具備的處理能力可以動(dòng)態(tài)的擴(kuò)展,更新和增強(qiáng),它能夠提供對(duì)流經(jīng)的用戶數(shù)據(jù)流進(jìn)行高層復(fù)雜的計(jì)算處理能力;其次,用戶數(shù)據(jù)包中能夠攜帶可以在主動(dòng)式結(jié)點(diǎn)中運(yùn)行的程序代碼,利用這一方式,用戶可以對(duì)網(wǎng)絡(luò)進(jìn)行編程,在網(wǎng)絡(luò)中靈活定制其所需的網(wǎng)絡(luò)業(yè)務(wù)和應(yīng)用,提供它們對(duì)自身特定數(shù)據(jù)進(jìn)行處理的功能。
