This paper provides an exhaustive performance analysis by simulation of the SCTP transfer protocol in WiMAX and Wi-Fi networks. We provide also a comparison of SCTP with both transfer protocols UDP for VoIP applications and TCP for FTP sessions, as SCTP can support these two types (elastic and non-elastic) of traffic. Finally, we study how SCTP performs when a mobile is multi-homed, i.e. connec...

n engl j med 366;11 nejm.org march 15, 2012 973 public insurance have marked the past six decades of health care in the United States. As the country struggles to emerge from a multiyear financial and economic crisis, policymakers and the public have increasingly homed in on those skyrocketing health care expenditures. What lessons can be drawn from the evolution, since 1950, in the sources of ...

This working paper describes a possible design for a new Internet namespace. A primary goal of creating this new namespace is to use the new namespace as a non-topological network-layer identifier for hosts. By doing so, a number of current routing issues, particularly those related to mobile hosts and to multi-homed campuses become simpler to solve. As this is a working paper, there is also di...

This document describes an optional extension to Router Advertisement messages for communicating default router preferences and morespecific routes from routers to hosts. This improves the ability of hosts to pick an appropriate router, especially when the host is multi-homed and the routers are on different links. The preference values and specific routes advertised to hosts require administra...

In this paper we propose a protocol for media streaming in wireless IP-capable mobile multi-homed hosts. Next generation wireless networks like 3G, 802.11a WLAN, Bluetooth are the target underlying technologies for the proposed protocol. Operation at the transport layer guarantees TCP-friendliness, error resilience, and independence from the inner workings of the access technology. Furthermore,...

A proper support for multimedia communications transport has to provide fault tolerance capabilities such as the preservation of established connections in case of failures. While multi-homing addresses this issue, the currently available solution based in massive BGP route injection presents serious scalability limitations, since it contributes to the exponential growth of the BGP table size. ...

This paper proposes an autonomic connection management mechanism for multi-homed mobile terminals. The knowledge repository and the case-based reasoning technique are used to enhance the autonomicity of the connection management. The multi-criteria handoff decision is the core of the mechanism. Analytic Hierarchy Process (AHP) and Simple Additive Weighting (SAW) are combined to make the handoff...

The Transmission Control Protocol (TCP) is the most used transport protocol to exchange reliable data between network devices. A considerable number of extensions have been implemented into TCP to achieve better performance. In this paper, we will present, describe, implement, and analyze a new protocol extension called Bandwidth-Aggregation TCP (BATCP), which enables the concurrent use of netw...
