Broadband service delivery has experienced a great evolution due to significant technological advances, which have favored the appearance of new business models. In this context, multi-play services denote the provisioning of several broadband services over a single broadband connection. In current deployments, there are a concrete number of services available (the same for all the customers), and bandwidth is pre-allocated by each service. This paper proposes a new approach that addresses this topic in a generic way. The new architecture does not impose any restrictions and handles the multi-service delivery with independence of the number of services. The new multi-play approach makes use of Carrier-Grade Ethernet to achieve network convergence, which means that the same network resources are used to carry all the broadband services. Carrier-Grade Ethernet is an umbrella term for a group of initiatives and standards that try to overcome the restrictions of Ethernet as carrier transport technology. Some of these standards such as Provider Bridges, Provider Backbone Bridges, PBB-Traffic Engineering, or Shortest Path Bridging are introduced. Finally, this paper proposes a built-in security scheme, which controls the admission to the network by preventing unauthorized users from accessing services. This approach is based on a modified version of IEEE 802.1X which permits the simultaneous establishment of multiple authentication processes, one per each service that the customer requests.

Advances of diverse wireless access technologies are defining the trends of future wireless networks, named Next Generation Wireless Networks (NGWN), where several access technologies will coexist and devices will be equipped with different network interfaces, in order to take advantage of each access technology. In NGWN communication maintenance is a concept willing to reach. Therefore, strategies to tackle mobility and multihoming issues are required. In this paper we propose an extension of HIP in order to cover challenges that end to end mobility presents in NGWN. Our approach consists on sending access technology related information before handover execution occurs, in order to optimize handover process. Moreover, the extension tackles QoS issues by sending application requirements as well as restrictions or improvements affecting its performance in the new access technology.
