We introduce a simple solution for the support of host mobility in the Internet called DIME (Dynamic Internet Mobility for End- Systems). DIME is based on dynamic address translation between the transport and network layers of end hosts, combined with a new out-of-band protocol that updates host-address bindings between communicating hosts opportunistically. It does not require modifications to the...
Forwarding data by name has been assumed to be a necessary aspect of an information-centric redesign of the current Internet architecture that makes content access, dissemination, and storage more efficient. The Named Data Networking (NDN) and Content-Centric Networking (CCNx) architectures are the leading examples of such an approach. However, forwarding data by name incurs storage and communication...
The first comparison of the performance of name-based content routing protocols based on distance vectors and link-states is presented. The protocols used for this comparison are the Named-data Link State Routing (NLSR) protocol, which is the main representative of name-based content routing based on link states, and the Distance-based Content Routing (DCR) protocol, which is the first name-based...
We revisit some of the basic premises of the Content Centric networking (CCN) and Named Data Networking (NDN) architectures, which have been proposed as alternatives to the IP Internet architecture in order to support more efficient access to content available in the Internet. We address the large overhead incurred in NDN and CCN by maintaining forwarding state for each Interest traversing a router...
Information Centric Multicasting (ICM) is introduced for the support of multicast groups with multiple sources in information centric networks. ICM supports two modalities: source-initiated multicasting and receiver-initiated multicasting. In contrast to all prior multi-source multicast approaches, routers do not have to flood the network from each multicast source, or know about the core or rendezvous...
Prior solutions for routing to multi-instantiated destinations (e.g., Internet multicasting and any casting, and routing in information centric networks) simply adapt existing routing algorithms designed for single-instance destinations, or rely on flooding techniques. As a result, they are unnecessarily complex and incur excessive overhead. A new approach for routing to multi-instantiated destinations...
Today's socket API requires an application to bind a socket to a network address before it can use the socket to communicate. Early bindings of names to addresses create significant bottlenecks, reliability problems, and force applications to manage complex lower-layer issues. Many approaches have been introduced to address this problem; however, all prior proposals introduce additional identifiers,...
Today's socket API requires an application to bind a socket to a transport-layer identifier (e.g., TCP80) and network-layer identifier (e.g., an IP address). These early bindings create significant bottlenecks, reliability issues, and force applications to manage complex lower-layer issues. Many approaches have been proposed to address these problems; however, all of them introduce additional identifiers,...
We introduce prefix ordering for efficient multicasting (POEM), the first approach to multicast routing in MANETs in which the network-wide dissemination of control information is independent of the number of groups and sources per group. POEM establishes a labeled directed acyclic graph (LDAG) rooted at an elected node in the MANET and assigns a prefix label to each node denoting its network location...
Applications that require the communication of multiple video streams can consume considerable bandwidth and computing resources, which poses a challenge for the widespread use of videoconferencing over the IP Internet. On the one hand, the bandwidth of the link connecting a given participant to a videoconferencing session may not be enough to support many video streams at bit rates of 500 kbps or...
