“…The lack of a common trust, privacy and security approach is just one of the shortcomings of the current Internet architecture. The Ambient Networks project, a European sixth frame work project identified some of the requirements to be addressed for their next generation communication architecture [7]. Haggle [8] identifies that the root cause for some of the usability deficiencies with regards to mobile devices today arises from the synchronous IP-based APIs presented to applications along with the numeric addresses as end-points.…”

The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architecture. While a clean slate approach to address these shortcomings is not an option in a realistic scenario, it is important to examine the architecture as a whole to address emerging network requirements and overcome existing shortcomings at the architecture level rather than engineering solutions to an existing inefficient one. This architectural re-examination should also facilitate discussion into what design principles for future generations of Network Architectures which will eventually replace the design tenets for the current Internet. While 3G and 4G systems were more focussed on convergence towards an All-IP network and some improvements in the core network, the architectural design remains stagnant with layered paradigms and inherent inefficiencies. A departure from this shackled approach could be the distinguishing feature of 5G systems and beyond. We claim that there is a pressing need to move towards a Next Generation Network architecture built to natively support requirements such as network resource abstraction, mobility, security, enhanced routing, privacy, context communications, QoS, parallel processing, heterogeneous networking etc. Instead of treating the network as just providing connectivity specified by endpoints, it is of great advantage to applications to recognise it as a service characterized by attributes, abstracted to a higher level to represent a collection of capabilities that the network offers. This uniform high level abstraction can effectively mask the heterogeneity and implementation discrepancies in the underlying infrastructure. Besides, in a network environment where an connectivity instance might transverse diverse business/ownership/capability domains, the approach proposed in this article can provide a transparent abstraction for resource negotiations across the domain to be available for end-to-end setup.

Abstract-Recent endeavors in addressing the challenges of the current and future Internet pursue a clean slate design methodology. Simultaneously, it is argued that the Internet is unlikely to be changed in one fell swoop and that its next generation requires an evolutionary design approach. Recognizing both positions, we claim that cleanness and evolution are not mutually exclusive, but rather complementary and indispensable properties for sustainable management in the future Internet.In this paper we propose the in-network management (INM) paradigm, which adopts a clean slate design approach to the management of future communication networks that is brought about by evolutionary design principles. The proposed paradigm builds on embedded management capabilities to address the intrinsic nature, and hence, close relationship between the network and its management. At the same time, INM assists in the gradual adoption of embedded self-managing processes to progressively achieve adequate and practical degrees of INM. We demonstrate how INM can be exploited in current and future network management by its application to P2P networks.

ivThe convergence of diverse but complementary wireless access technologies and inter-operation among administrative domains have been envisioned as crucial for the next generation wireless networks that will provide support for end-user devices to seamlessly roam across domain boundaries. The integration of existing and emerging heterogeneous wireless networks to provide such seamless roaming requires the design of a handover scheme that provides uninterrupted service continuity while facilitating the establishment of authenticity of the entities involved. The existing protocols for supporting re-authentication of a mobile node during a handover across administrative domains typically involve several round trips to the home domain, and hence introduce long latencies. Furthermore, the existing methods for negotiating roaming agreements to establish inter-domain trust rely on a lengthy manual process, thus, impeding seamless roaming across multiple domains in a truly heterogeneous wireless network.In this thesis, we present a new proof-token based authentication protocol that supports quick reauthentication of a mobile node as it moves to a new foreign domain without involving communication with the home domain. The proposed proof-token based protocol can also support establishment of spontaneous roaming agreements between a pair of domains that do not already have a direct roaming agreement, thus allowing flexible business models to be supported.We describe details of the new authentication architecture, the proposed protocol, which is based on EAP-TLS and compare the proposed protocol with existing protocols. roaming and universal access with the convenience of having a single bill for all services. INTER-DOMAIN AUTHENTICATION FOR SEAMLESS ROAMING IN HETEROGENEOUS WIRELESS NETWORKS BACKGROUND AND MOTIVATIONA mobile user desires to be "Always Best Connected" [4], which means the user is driven by a quest for higher speed and lower prices. The user also wants a ubiquitous coverage so that he can get access to network resources from anywhere, anytime. However, data rate and coverage are complementary to each other. Higher data rates are easier to provide for a smaller coverage. For example, a 3G network has a wider coverage but slower speeds; whereas WirelessLANs have higher speeds but smaller coverage.Thus, wide wireless network coverage with high data rates is not possible with a single technology and a single wireless provider. A heterogeneous wireless network will consist of wireless networks of multiple technologies operated by multiple service providers. A mobile user must be able to discover and select the best service provider at a given location [5]. As he moves in space and time, he must be able to seamlessly roam from one network to the other in a secure manner, being always connected to the best network. In particular, the solutions that support 3 such seamless roaming should ensure that the authenticity of the entities as it connects to the new domains is properly established. is the handover delay...
