Round Robin based Intermittent Periodic Transmit (RR-IPT) has been proposed which achieves highly efficient multi-hop relays in multi-hop wireless backhaul networks (MWBN) where relay nodes are 2-dimensionally deployed. This paper newly investigates multi-channel packet scheduling and forwarding scheme for RR-IPT. Downlink traffic is forwarded by RR-IPT via one of the channels, while uplink tra...

Routers in the Internet do not perform any verification of the source IP address contained in the packets, leading to the possibility of IP spoofing. The lack of such verification opens the door for a variety of vulnerabilities, including denial-of-service (DoS) and man-in-the-middle attacks. Currently proposed spoofing prevention approaches either focus on protecting only the target of such at...

The transport of connectionless data is necessary for the compatibility of emerging wide area ATM networks with existing computer networks. This paper investigates the design and performance of a virtual connectionless network overlayed on top of cell-based connectionoriented ATM networks. The virtual connectionless network is made possible by utilizing connectionless servers. Two packet forwar...

This paper proposes an isolation layer – a shim – between inter-domain routing and packet forwarding. The job of this layer is to coordinate between Autonomous Systems (AS’s) on when and how to modify the forwarding state to ensure interdomain routing loops do not cause forwarding loops. The benefits of a consistency layer are twofold. First, it prevents the creation of transient inter-domain f...

In this paper, we propose a novel Secure Name Service (SNS) framework for enhancing the service availability between collaborative domains (e.g., extranets). The key idea is to enforce packet authentication through resource virtualization and utilize dynamic name binding to protect servers from unauthorized accesses, denial of service (DOS) and other attacks. Different from traditional static n...

In this paper, we investigate the performance of M-LANMAR by implementing the protocol in Linux platform. With existing Linux implementation of ODMRP, we compare the performance of M-LANMAR to that of ODMRP. The two components constitute MLANMAR implementation: routing and packet forwarding. Because M-LANMAR requires packet manipulations (e.g., the source duplicates the packet and each landmark...

Network virtualization provides the ability to run multiple concurrent virtual networks over a shared substrate. However, it is challenging to design such a platform to host multiple heterogenous and often highly customized virtual networks. Not only high degree of flexibility is desired for virtual networks to customize their functions, fast packet forwarding is also required. This paper prese...

Problem statement: In mobile adhoc network, broadcasting is a common operation for route establishment and for sending control and emergency messages. Most of the existing broadcasting algorithms consider broadcasting from single source node and consider only single message broadcasting. Initiating multiple messages broadcasting from multiple sources is a challenging task which requires minimum...

In mobile ad hoc network, broadcasting is a common operation for route establishment and for sending control and emergency messages. Initiating multiple messages broadcasting from multiple sources is a challenging task which requires minimum number of retransmission by the forwarding nodes. Network coding-based broadcasting is proposed which focuses on reducing the number of transmissions each ...

The explosive growth of Internet users, the increased user demand for bandwidth, and the declining cost of technology have all resulted in the emergence of new classes of high-speed distributed IP-router architectures with packet-forwarding rates on the order of gigabits, or even terabits, per second. This paper develops an analytical framework for modeling and analyzing the impact of technolog...
