End-to-end inverse multiplexing for mobile hosts

Abstract

This paper presents a framework for the creation of transport protocols for mobile hosts that use multiple link layers simultaneously for the same connection. This abstraction provides an end-to-end transport layer channel between two applications that do not have to be aware of host mobility. The channel is composed of multiple network layer sub-channels. A sub-channel is an end-to-end network layer connection that is mapped to one physical interface. Inverse multiplexing is used at the transport level to divide application data into sub-channels, and a rate-based transmission mechanism provides congestion avoidance. The same mechanism is used to differentiate transmission losses from congestion losses, resulting in good throughput in lossy wireless links. Experimental results for two protocols created using this framework validate our design choices.

Design, implementation, and evaluation of a Programmable Bandwidth Aggregation System for home networks

“…Application-agnostic BASs use a special network-layer (Chebrolu et al, 2005;Hari et al, 1999;Phatak and Goff, 2002) or transport-layer protocol (Argyriou and Madisetti, 2003;Hsieh and Sivakumar, 2002;Magalhaes and Kravets, 2001) to distribute packets among computers in the group (the minimal group having the only one multi-homed computer to distribute packets among the multiple External Interfaces) and the computers in the group use their External Interfaces to cooperatively forward packets to the host with Internet Connectivity. By working at the network layer or the transport-layer, applicationagnostic BASs can aggregate bandwidth without application awareness.…”

“…By working at the network layer or the transport-layer, applicationagnostic BASs can aggregate bandwidth without application awareness. However, application-agnostic BASs need to modify the protocol stacks of computers in the group (Argyriou and Madisetti, 2003;Chebrolu et al, 2005;Hari et al, 1999;Magalhaes and Kravets, 2001), deploy a proxy between the Internet host and computers in the group (Carter and Kravets, 2002;Kim and Shin, 2005;Rodriguez et al, 2004;Sharma et al, 2004), or modify the protocol stack in the Internet host (Argyriou and Madisetti, 2003;Chebrolu et al, 2005;Hari et al, 1999;Kim and Shin, 2005;Magalhaes and Kravets, 2001). Application-agnostic BASs modify computers in the group in order to inverse multiplex (Duncanson, 1994) and distribute packets among the External Interfaces.…”

Increasing wide-area download throughputs on the roads by trunking multiple cellular channels over a vehicular ad hoc network

“…In [6], the authors presented a framework for creating transport protocols for mobile hosts to simultaneously use multiple link layers for the same connection. In this study, each mobile host has multiple wireless interfaces and the traffic of a connection is striped over these interfaces.…”

“…In [22] MOPED explores efficient inverse multiplexing at the transport level to aggregate multiple wireless channels and differentiate transmission losses from congestion losses in wireless links. Similarly, in [23] MOPED explores how non-conflicting local area wireless technologies can be used to improve throughput and minimize mobility problems.…”
