In this paper we present PACK (Predictive ACKs), a novel end-to-end Traffic Redundancy Elimination (TRE) system, designed for cloud computing customers. Cloud-based TRE needs to apply a judicious use of cloud resources so that the bandwidth cost reduction combined with the additional cost of TRE computation and storage would be optimized. PACK's main(More)
Online hotel searching is a daunting task due to the wealth of online information. Reviews written by other travelers replace the word-of-mouth, yet turn the search into a time consuming task. Users do not rate enough hotels to enable a collaborative filtering based recommendation. Thus, a cold start recommender system is needed. In this work we design a(More)
This work presents a thorough investigation of the structure of multicast trees cut from the Internet and power-law topologies. Based on both generated topologies and real Internet data, we characterize the structure of such trees and show that they obey the rank-degree power law; that most high degree tree nodes are concentrated in a low diameter(More)
Communicating during disaster times is crucial for both survivors and rescue forces. While fast reaction is critical communication infrastructures, wired and cellular, are often lost, and cannot be restored in a timely fashion. In this paper we present HelpMe, a self learning opportunistic ad-hoc system, which enables smartphone-based ad-hoc communications(More)

In this paper we present Celleration, a novel gateway-to-mobile Traffic Redundancy Elimination (TRE) system, designed for the new generation of data-intensive cellular networks. Cellular TRE needs to account for the mobile device's limited battery power and the characteristics of the cellular network such as users' mobility, high packet-loss and long(More)
The Border Gateway Protocol (BGP), the defacto routing protocol of the internet, is known to generate excessive traffic following changes in the underlying backbone topology. Specifically, BGP was shown to converge very slowly and have a worst case of O(N !) message complexity after a fail down (detachment) of a network in [1, 2]. The authors show that BGP(More)
