1 Introduction In today's wired and wireless networks, the trends in networking technology very much point to a dominance of Internet technology with all its flavours. IP is the common " lingua franca " to enable the exchange of data across various networks. There is, however, an increasing divergence in the network control layer: different control(More)
— Providing end-to-end communication in heterogeneous internetworking environments is a challenge. Two fundamental problems are bridging between different internetworking technologies and hiding of network complexity and differences from both applications and application developers. This paper presents abstraction and naming mechanisms that address these(More)
The General Packet Radio Service (GPRS) is currently being standardized by the European Telecommunications Standard Institute (ETSI) to extend the services provided by the Global System for Mobile Communications (GSM). GPRS is dedicated to support packet-oriented traffic, e.g. Internet traffic. Packet oriented transmission is by nature better suited to(More)
<i>Ambient Networks</i> interconnect independent realms that may use different local network technologies and may belong to different administrative or legal entities. At the core of these advanced internetworking concepts is a flexible naming architecture based on dynamic indirections between names, addresses and identities. This paper gives an overview of(More)
This paper provides a comparative overview of the candidates being discussed as successors for current mobile broadband data networking technologies. The comparison is based on typical network operator requirements that are summarized under the term &#x201C;Next Generation Mobile Networks&#x201D; (NGMN) and governed by a comprehensive approach to technology(More)
Ambient Networks (AN) project. This paper describes the Overlay architecture. Its name is derived from the use of an overlay control plane that allows for internetworking between different network technologies, as well as for control of functionality that is today found in different and sometimes proprietary middleboxes such as NATs, firewalls, mobility(More)
