Twitter has received much attention recently. In this paper, we investigated the real-time nature of Twitter, devoting particular attention to event detection. An important characteristic of Twitter is its real-time nature. We investigate the real-time interaction of events such as earthquakes in Twitter and propose an algorithm to monitor tweets and to detect a target […]
Design, Implementation, and Performance of a Load Balancer for SIP Server Clusters
This paper introduces several novel load-balancing algorithms for distributing Session Initiation Protocol (SIP) requests to a cluster of SIP servers. Our load balancer improves both throughput and response time versus a single node while exposing a single interface to external clients. We present the design, implementation, and evaluation of our system using a cluster of […]
