Networks have become multipath: mobile devices have multiple radio interfaces, datacenters have redundant paths and multihoming is the norm for big server farms. Meanwhile , TCP is still only single-path. Is it possible to extend TCP to enable it to support multiple paths for current applications on today's Inter-net? The answer is positive. We carefully(More)
Successful deployment of new network protocols on the Future Internet is not a trivial task. Deployable protocol design is necessary but not sufficient condition for protocol's success, unless it takes all stakeholders involved in the deployment process into account. This paper investigates the challenges of deploying a new transport protocol on the(More)
Multipath TCP (MPTCP) is a resource pooling mechanism which splits data across multiple subflows (paths) and ensures reliable data delivery. Although Multipath TCP is a relatively small technical change to the TCP protocol providing improved resilience, throughput and session continuity, it will have considerable impact on the value networks and business(More)
Over the past decades, the fundamental principles of the Internet architecture have not significantly changed. However, Internet evolution and its effects on participants' interests have triggered the need for redefining these design principles. " Design for Tussle " is an aspiration for future network designs , which enables the involved stakeholders to(More)
During the last decade the Internet has faced an architectural stagnation due to lack of wide scale adoption of new communication protocols. A significant reason for non-adoption is that the conflicting interests of networked stakeholders involved in the diffusion process are not understood or taken into account during the protocol development. This paper(More)
Fourth Generation mobile devices incorporate multiple interfaces with diverse access technologies. The current Mobile IP protocol fails to support the enhanced fault tolerance capabilities that are enabled by the availability of multiple interfaces. In particular, established Mobile IP communications cannot be preserved through outages affecting the Home(More)
This document presents a proposal for the architecture of the Future Internet. The architecture has been developed by the Trilogy collaborative research project, whose focus is the development of the current Internet, and in particular its network and transport layers. The key challenges identified include scaling and flexibility in the global routing(More)
This document describes the resource control work done in Trilogy during the second year of the project. The work items fall in one of the two directions Trilogy is pursuing: 1. Accountability exposes to the network the congestion users cause on the path to the destination, allowing the network to monitor and enforce desired policies. This documents(More)
