Opening the way for convergence in the 5G era with MPTCP

Olivier Bonaventure, Nicolas Men

In the emerging architecture for 5G networks, the ATSSS function (Access Traffic Steering, Switching & Splitting) will play a key role in managing data traffic between 3GPP access & non-3GPP access (such as WiFi). In this paper we briefly describe how this works and introduce Multipath TCP (MPTCP), the underlying protocol which has been selected by 3GPP for ATSSS

Hybrid access as an upgrade to fixed wireless

Graham Turnbull

Some operators are rolling out Fixed Wireless Access (FWA) which implies connecting TV's, laptops, phones, tablets, and smart home controls to the Internet over wireless networks. We propose supplementing FWA with fixed line connectivity using our hybrid access solution to offload traffic from the wireless network and to ensure consistent service for end users

How hard can it be? Adding Multipath TCP to the upstream kernel

Mat Martineau, Matthieu Baerts, Christoph Paasch and Peter Krystad

Multipath TCP is a recent TCP extension that allows devices like today's smartphones or laptops to send and receive data over multiple interfaces for better resource utilization, throughput, and reaction to failures and handover. While interest is growing in this new TCP extension, this protocol is not supported by the upstream Linux kernel. A community project is underway to add Multipath TCP to the upstream Linux kernel but is facing some different challenges: from the protocol itself, to creating a design that does not adversely affect TCP or networking structures, to extending networking code without expensive indirection

Can 4G networks provide broadband services?

Olivier Bonaventure, Graham Turnbull

Broadband services are now as important as electricity for most households. In some countries, good network connectivity is an important consideration when buying a house or an apartment. The importance of always-on broadband services will continue to grow in the near future. Broadband services are typically provided by fixed networks using either xDSL or cable technologies but some operators have deployed fixed services based on mobile networks. This article looks at the suitability of 4G networks as the main connection to the Internet.

Network-assisted MPTCP: Use cases, deployment scenarios & operational considerations

Mohamed Boucadair, Christian Jacquenet, Olivier Bonaventnure, Wim Henderickx, Robert Skog

Network-Assisted MPTCP deployment models are designed to facilitate the adoption of MPTCP for the establishment of multi-path communications without making any assumption about the support of MPTCP by the communicating peers. MPTCP Conversion Points (MCPs) located in the network are responsible for establishing multi-path communications on behalf of endpoints, thereby taking advantage of MPTCP capabilities to achieve different goals that include (but are not limited to) optimization of resource usage (e.g., bandwidth aggregation), of resiliency (e.g., primary/backup communication paths), and traffic offload management. This document describes Network-Assisted MPTCP uses cases, deployment scenarios, and operational considerations

A MPTCP option for network-assisted mptcp

Mohamed Boucadair, Christian Jacquenet, Olivier Bonaventnure, Denis Behaghel, Stefano Secci, Wim Henderickx, Robert Skog, Suresh Vinapamula, SungHoon Seo, Wouter Cloetens, Ullrich Meyer, Luis M. Contreras, Bart Peirens

Because of the lack of Multipath TCP (MPTCP) support at the server side, some service providers now consider a network-assisted model that relies upon the activation of a dedicated function called MPTCP Conversion Point (MCP). Network-Assisted MPTCP deployment models are designed to facilitate the adoption of MPTCP for the establishment of multi-path communications without making any assumption about the support of MPTCP by the communicating peers. MCPs located in the network are responsible for establishing multi-path communications on behalf of endpoints, thereby taking advantage of MPTCP capabilities to achieve different goals that include (but are not limited to) optimization of resource usage (e.g., bandwidth aggregation), of resiliency (e.g., primary/backup communication paths), and traffic offload management

Comparing Hybrid access networks solutions

Denis Périquet

To cope with growing user appetite for bandwidth, telecommunication network operators are exploring various solutions to combine different access network technologies together. This will pave the way for hybrid access networks, i.e. access networks that combine very different technologies such as DSL and LTE. In this white paper, we compare different technical solutions that can be used to create such hybrid access networks. In particular, we compare the benefits of the Multipath TCP-based solutions to network-layer solutions. Furthermore, our measurements done on three widely deployed DSL access routers show that a software-based solution using Multipath TCP can achieve high bandwidth on existing devices
