An important requirement for Internet protocol (IP) networks to achieve the aim of ubiquitous connectivity is network mobility (NEMO). With NEMO support we can provide Internet access from mobile platforms, such as public transportation vehicles, to normal nodes that do not need to implement any special mobility protocol. The NEMO basic support protocol has(More)
Since the ARPAnet, network designers have built localized mechanisms for statistical multiplexing, load balancing, and failure resilience, often without understanding the broader implications. These mechanisms are all types of resource pooling whichmeans making a collection of resources behave like a single pooled resource. We believe that the natural(More)
Host mobility has traditionally been solved at the network layer, but even though Mobile IP has been standardised for 15 years, it hasn't been supported by operators. IP's double role as a location identifier and communication endpoint identifier brings a number of functional and performance problems. We argue that the best place to handle mobility is at(More)
Multihoming (i.e., the connection to the Internet through multiple providers), has been widely adopted by Internet sites, mainly to provide fault tolerance. In the multihoming solution currently deployed in the IPv4 Internet, the multihomed site announces a single address block through all its providers using Border Gateway Protocol (BGP). As a result, for(More)
Network Mobility (NEMO) Basic Support Protocol enables mobile networks to change their point of attaehment to the Internet, while preserving estahlished sessions of the nodes within the mobile network. NEMO basie solution is an extension of Mobile 1Pv6 and it is based on tunnelling, whieh leads to sUboptimal routing, packet overhead and latency, especially(More)
In this paper, we propose the use of prefix visibility at the interdomain level as an early symptom of anomalous events in the Internet. We focus on detecting anomalies which, despite their significant impact on the routing system, remain concealed from state of the art tools. We design a machine learning system to winnow the prefixes with unintended(More)
Fourth-generation mobile devices incorporate multiple interfaces with diverse access technologies. The current Mobile IPv6 protocol fails to support the enhanced fault tolerance capabilities that are enabled by the availability of multiple interfaces. In particular, established MIPv6 communications cannot be preserved through outages affecting the home(More)
