Abstract
An attractive target for a computer system attackeris the router. An attacker in control of a routercan disrupt communication by dropping or misrout-ing packets passing through the router. We present aprotocol called WATCHERS that detects and reacts torouters that drop or misroute packets. WATCHERSis based on the principle of conservation of ow ina network: all data bytes sent into a node, and notdestined for that node, are expected to exit the node.WATCHERS tracks this ow, and detects routers thatviolate the conservation prin ....etc

Router
Router is a device which extracts the destination address from the incoming packet and sends it to the destination through the optimal path. Directing data between portions of a network is the purpose of a router.

hi,

I am a student of Dr.A.I.T pursuing my M.tech fourth semester.I had submitted my project report which was based on the paper with the title Rate and Delay guarantees provided by clos packet switches . The report has been rejected for modifications.I kindly request you to guide me through in preparing my project report.

Differentiated Bandwidth Allocation with TCP Protection in Core Routers


Abstract

Differentiated Services (DiffServ) networks categorize routers into edge routers and core routers.In core routers, one of the technological challenges is how to implement differentiated bandwidth allocation and TCP protection together with low complexity.We present an Active Queue Management (AQM) scheme called CHOKeW. A method is borrowed from a previous scheme, CHOKe, which draws a packet at random from the buffer, compares it with the arriving packet, a ....etc

Abstract:
IEEE is currently standardizing a new high-speed backbone technology for MANs--Resilient Packet Ring (RPR). A key performance objective of RPR is to achieve high utilization, spatial reuse, and fairness simultaneously. However, the algorithms proposed in current draft standards have some critical limitations. As shown in unbalanced traffic scenario, drafts RPR algorithm will suffer from dramatic bandwidth oscillations within nearly the entire range of the page link capacity. In this paper, we propose a new dynamic ....etc
