Abstract

To achieve fair bandwidth allocations, router mechanisms are attained in the network. Router mechanisms designed to achieve fair bandwidth allocations, like RED, have many desirable proper ties for congestion control in the Internet. In this paper, we propose an architecture that contains edge router and core router, significantly reduces this implementation complexity yet still achieves fair bandwidth allocations. We apply this approach to core routers that is, a nearby region of the network and we difference between edge routers and core routers. Edge routers maintain per flow state; they estimate the incoming rate of each flow and insert a label into each packet header based on this estimate. Core routers maintain no per flow state; they use FIFO packet scheduling. We call the scheme Core-Stateless Fair Queuing. We present simulations and analysis on the performance of this approach, and discuss an alternate approach.

Abstract

In today’s life people face lot of accidents, to save their lives we try to notify it to the hospitals and authorised persons. By this devices reducing time of notifying the emergency situation to the authorised person and hospitals, how this devices reduces the timing of notify the situation at that time surrounding peoples of that accidental area are in nervous condition. So the people didn’t know to call the emergency services at that time the impasse notifier. The emergency is sensed by the impasse notifier sensors and emergency alert will transmitted in text message using GSM (Global System for Mobile). The Emergency Location is detected by the GPS (Global Positioning System) and location is transmitted through text message using GSM.
