Project Abstract (Project overview - 25 lines max.):

The trend today is for easy, ubiquitous access to advanced broadband services. People will expect to be able to connect to a broadband network for business and personal use, irrespective of time, terminal and location. The consumed content may be generated in any part of the network and will include both professional production and user generated content. Access to content will involve both peer-to-peer usages as well as centralised service delivery.

MARCH aims at significantly lowering the cost of converged broadband service delivery by establishing scalable multilink network architectures. Although a multiplicity of fixed and mobile networks exists today there has been little real attempt to achieve harmonisation or interworking. Today’s terminals incorporate multiple access technologies, but the strategies for connecting to IP networks generally result in simple selection of one of the available networks. The potential for simultaneously using the available access technologies in a multi-link manner has yet to be exploited.

MARCH addresses key issues for ubiquitous broadband access with a particular focus on service provision under the new broadband reality and network architecture effective for connecting all types of users, either fixed or on the move. The project aims at convergence of broadband, mobile, and broadcast approaches and its application to urban and rural deployment.

Focus areas are:

1) Multilink network technology

Convergence between broadband, mobile, and broadcast services is central in delivering ubiquitous and seamless services. MARCH focuses on the techniques enabling a multilink architecture whereby terminals operate dynamically over several broadband/broadcast access networks simultaneously enabling intelligent multi-service provision offering enhanced service availability and improved resource utilisation.

2) Modular scalable architecture

MARCH will recommend a modular scalable architecture for multilink networks and provide standardisation inputs such that networks can be realised at significantly lower cost. Networks have to scale well both allowing initial development with low demand and subsequent flexible growth.

1  Project Summary

1.1  Main focus

The trend today is for widespread, easy access to advanced broadband services. People will expect to be able to connect to a broadband network for business and personal use, irrespective of time, terminal and location. The consumed content may be generated in any part of the network and will include both professional production and user generated content. Access to content will involve both peer-to-peer usages as well as centralised service delivery.

MARCH aims at significantly lowering the cost of converged broadband service delivery by establishing scalable multilink network architectures, as illustrated in Figure 1. The broadcast and telecommunications landscape is today characterised by a multiplicity of heterogeneous access technologies, both fixed and mobile. Users can connect to a broadband service using one of several technologies; they have access to a mobile network and to a satellite network and more and more to a digital terrestrial broadcast network. These technologies have generally evolved from legacy architectures with little real attempt to achieve harmonisation or interworking. Whilst today’s terminals incorporate multiple access technologies, the strategies for connecting to IP networks generally result in simple selection of one of the available networks. For example many mobile handsets have both 3G and WiFi interfaces, but the user has to choose between the networks one at a time. The potential for simultaneously using the available access technologies in a multi-link manner has yet to be exploited. Additionally, requiring users to manually switch between different access networks and maybe also to manually specify which applications may use which networks at which time is clearly impractical. In mobile scenarios the characteristics of the networks may also change rapidly, making manual control not only impractical but also impossible. However, users still need a way to control network usage, due to for example cost considerations. This reasoning illustrates a need for automatic adaptation where user preferences are taken into account.

Figure 1. In a multilink scenario a user can connect to the network using several links simultaneously

Now, is it beneficial to use several networks simultaneously? Yes it is and MARCH will show why both the user and the network service providers benefit and how it can be achieved in the practical world. For example the user can be offered a significant increase in capacity and the broadband network can reach further out. The project aims at convergence of broadband, mobile, and broadcast approaches and its application to urban and rural deployment. In short MARCH addresses key issues for ubiquitous broadband access with a particular focus on multimedia service provision and network architecture effective for connecting all types of users, either fixed or on the move.

1.2  State-of-the-art situation

Combining several access network links for enhancing performance (back-up, throughput, etc) is not new. Channel bonding (as exists in Ethernet switches), layer 2 (link) aggregation and even layer 3 (IP) aggregation have been considered but with a lot of drawbacks. The former method is attached to one technology only; the second is for one Internet Service Provider only and the latter is a partial solution based on IP multi-homing without considering inbound traffic.

The use of multilink in the Internet is known but is generally limited to selecting a single path, with the alternative paths being used in the case of transmission failure. Three approaches are however of particular relevance:

·  Recent work in the IETF Monami6 group has extended the Mobile IP protocol to encompass multiple interfaces on the terminal. This is achieved through establishing several tunnels between the terminal and a network agent. Such an approach could enable the terminal to distribute multiple communications over several tunnels. However, the notion of using several tunnels for one service is not envisaged.

·  Multi-homing protocols (SHIM6, HIP) allow each end of a communication link to know the pool of addresses of the other end of the link. The simultaneous use of these addresses is however not envisaged, the approach targeting address switching in the event of a link failure.

·  SCTP proposes a transport layer approach whereby all possible addresses are exchanged at the start of a connection. Once again the using multiple links for a given communication is not envisaged.

The always best connected concept as envisaged in [1], [2], [3] consists of selecting one or more access networks among a plurality of access networks for connecting the multi-mode terminal with any other terminal or service supporting or not the always best connected architecture. Connecting heterogeneous networks and devices at various locations will enhance the user experience in terms of improved service performance, perceived Quality of Service (QoS) and reduced costs

Both ITU [4] and ETSI [5] have conducted standardisation work aiming at modular scalable network within their next generation network (NGN) initiative. There are also other initiatives for modularity, such as open base station architecture initiative (OBSAI) [6] and similarly for Worldwide Interoperability for microwave access (WiMAX) [7]. These inactivates are ongoing work, but they are not covering the multilink issues so far. Also monolink network solutions are today lacking modularity.

Previous research has addressed several issues like the overall architecture, the end to end QoS, signalling and advertising and the link selection based on user profile, economical inputs (e.g. price) and network status. [2] focuses mainly on an end to end QoS framework providing a consistent QOS whatever the number of [wireless] hops crossed by the end-to-end bearer. [3] focuses on a middleware architecture that abstracts the usage of different modules for adapting the communication to the network interface.

A number of European and North American projects have also envisaged such multi access network architecture:

Ambient Networks [8] introduces a multi-access functionality by specifying a multi-radio resource management (MRRM) entity that can manage the handover acting as the network interface selector. It is present in the terminal and also in the network and controls the forwarding point (FP) that realizes the mapping between high level flows (e.g. HTTP/TCP) to access network flows (e.g. UMTS/3G ). Such mapping results in an active access flow that operates an access network path temporarily until the next handover occurs, ordered by the MMRM. In a particular architecture embodiment, the terminal can also operate the multi radio transmission diversity (MRTD) at different levels including IP level. The transmission diversity consists basically into sending/repeating a data packet several times over several access interfaces. However [8] also envisages the case where packets are sent using, in parallel several interfaces for increasing the bandwidth. MARCH will address this issue with different basic requirements and assumptions including network architecture composed of different access network operators, supporting and extending mobile IP, focusing on video applications, etc.

Multinet [9] aims at designing an always best connected network infrastructure. As with Ambient, Multinet focused on a QOS framework and the network interface selector. They have based their work on NEMO [10], a multi-homing router that acts as a front-end for handling multi-interface management allowing the terminals to operate the infrastructure seamlessly. Although the router can be considered embedded into a terminal this solution is suitable for mobile networks like in trains, automotive contexts.

Daidalos [11] deals with heterogeneous networks and aims at unifying the access to networks whatever their characteristics (including one way broadcast network). Besides building their architecture on IPv6, they have taken various directions ranging from mobility management, virtual identity to broadcast/unicast inter-working. However the typical scenario of using concurrent access networks is not part of the scope.

The Tetherless Computing [12] concept enables communications to be maintained under varying access network conditions through the implementation of a proxy enabling multi-links to be established in an opportunistic manner.
