The Named Data Networking (NDN) and Content-Centric Networking (CCNx) architectures use a forwarding plane that requires large Forwarding Information Bases (FIB) listing the next hops to name prefixes and Pending Interest Tables (PIT) that maintain per-Interest forwarding state. We introduce CCN-RAMP (Routing to Anchors Matching Prefixes), a new approach to content-centric networking that substitutes...
Using Interests (requests that elicit content) and maintaining per-Interest forwarding state in Pending Interest Tables (PIT) are integral to the design of the Named Data Networking (NDN) and Content-Centric Networking (CCNx) architectures. However, using PITs makes the network vulnerable to Interest-flooding attacks, and PITs can become very large. It is shown that in-network caching eliminates the...
Multicasting is a way to deliver copies of single message to multiple recipients at different locations. On the traditional internet, group members join specific multicast address through membership management protocol and packets are delivered along the path tree built by multicast routing protocol. Now we consider how multicast-style communication can be designed in id/locator separation environment...

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...
In a network, bridging nodes are those nodes that from a topological perspective, are strategically located between highly connected regions of nodes. Thus, they have high values of the Bridging Centrality (BC) metric. We recently introduced the Localized Bridging Centrality (LBC) metric, which can identify such nodes via distributed computation, yet has an accuracy equal to that of the centralized...
Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, efficient multicasting in...
Sharing communications are not easy to do in the mobility networks (MONETs) for the limited bandwidth and the overhead of tunneling. Multicast is an intuitive method to solve this problem. To improve the performance, the multicast topology should be redesigned for the MONETs. We proposed an efficient communication algorithm with multicast schemes in a network mobility (NEMO) environment. The Mobile...
With the development of broadband technologies, more and more multimedia contents such as video or bulk file are being distributed over the Internet. However, an important issue to be resolved is how to construct an efficient overlay to provide users with the acceptable throughput and delay, while receiving multimedia contents. Therefore, this paper designs a tree construction algorithm by distributing...
Application layer multicast (ALM) is an alternative to overcome many problems that prevent IP multicast from widely using. However, when the overlay route changes, it takes time for end-hosts to update new routing table. In this paper, we propose Treemap a technique to alleviate this problem. The main contribution of Treemap is to perform application layer routing which is self contained in a packet...
Thanks to the advances in wireless technologies, mobile vehicular networks are likely to become the most relevant form of mobile ad hoc networks (MANET). Vehicular communication which facilitates the exchange of information between vehicles is the prerequisite not only for extending the access to Internet while on the road, but also to cater for special applications such as of road traffic and travel...
In recent years wireless mesh networks have been deployed and grown in popularity in many metropolitan areas. The deployment of such networks has allowed clients to gain access to publicly available broadband networks. The lack of standards and support for multicasting over wireless mesh networks makes this area very challenging as well as providing much scope for improvement. For first time in this...
IP multicast is an efficient and scalable network layer delivering method for multimedia content to a large number of receivers across the Internet. It saves the network bandwidth and optimizes the processing overhead of the source. However, current IP multicast deployment is still facing many deployment complexities. In particular, the duality and the strong relationship between multicast addressing...
In this paper we propose a new scheme named Differentiated QoS Multicast (DQM) based on the Source Specific Multicast (SSM) model in order to provision limited qualitative QoS channels for supporting heterogeneous end users. Based on Service Level Agreements, both sources and group members should select a specific QoS channel available from the network for group data transmission, and arbitrarily...
Bi-directional shared tree is an efficient routing scheme for interactive multicast applications with multiple sources. Given the open-group IP multicast service model, it is important to support sender access control in order to prevent group members from receiving irrelevant data, and also to protect the multicast tree from denial-of-service (DoS) attacks. Compared with source specific and uni-directional...
End-system multicasting (ESM) is a promising application-layer scheme that has been recently proposed for implementing multicast routing in the application layer as a practical alternative to the IP multicasting. Moreover, ESM is an efficient application layer solution where all the multicast functionality is shifted to the end users. However, the limitation in bandwidth and the fact that the message...
Multicast patching is one of the techniques to reduce the burden of a video on demand (VOD) server. A novel patching mechanism by using multi-homing has placed its logical channel into another network interface of a client terminal. The performance of proposed patching mechanism is presented via numerical analysis. In summary, our proposed scheme modifies multicast patching model using extended client...
Multicast communication in the internet has been growing rapidly over the last few years. Internet applications transmit data from one sender to many receivers, In Multicast protocols while packet broadcasts to a group of receivers the total numbers of packets swamped in a network decrease. Multicast communication reduces both the time it takes to send data to a large no of receivers and the amount...
Multicast is an efficient method to transmit datagrams in the Internet. In this paper, we provide a multicast algorithm in a network mobility (NEMO) environment. We propose the mobile router forwarding scheme (MRFS) algorithm. There are two advantages in the MRFS algorithm. First, MRFS reduces the storages in every MR especially in the TLMR (top level MR). Second, MRFS transmits multicast datagrams...
Internet service providers increasingly wish to monitor the performance of customer traffic within their networks. This paper addresses the problem of scalably performing one-way loss measurements across specific network paths. Our solution addresses the issue of scale by exploiting measurement features of the deployed network infrastructure to a large degree. There are three components. Firstly,...
