Many methods for finding the optimal design of an optical packet switching ring network are without the performance guarantees, leading to the unexpected network behavior in terms of the QoS performance that network offers to its clients. The inter-dependability between the network QoS performances and the cost optimal design of an optical packet switching ring with a single tunable transmitter...

This paper proposes a dynamic shared-memory packet buffer management algorithm for a protocol processor in a network terminal. The protocol processor is located in a network interface card (NIC). In general, two types of packet buffer management algorithms, static and dynamic, can be used in a NIC; the dynamic buffer management algorithms work better than the static ones for reducing the packet...

Internet is built as a packet-switching network. The kernel function of Internet infrastructure, including routers and switches, is to forward the packets that are received from one subnet to another subnet. The packet forwarding is accomplished by using the header information extracted from a packet to look up the forwarding table maintained in the routers/ switches. Due to rapid growth of net...

A packet dropping and message tampering attack contains data which routed between source and destination. Packet dropping attack happens accidently or deliberately on network or packet switching network. Message tampering attack causes measure problem in message transmission activity, due to unauthorized party tampered message and can change message contains so it hard to detect that tampered m...

Packet Tracer uses two representation schemes to represent a network: logical workspace and physical workspace. In this paper, our implementation uses these two schemes to build networks and to demonstrate our experiments. Logical workspace is used to build a logical topology and physical workspace is used to arrange devices physically. Packet Tracer as demonstrated in this paper has an operati...

Mobile IPv6 allows a Mobile Node to remain reachable by a Correspondent Node while roaming from one network to another network. In Mobile IPv6, a Mobile Node directly updates its current location information to a Correspondent Node using a route optimization method. Route optimization helps to culminate the packet delay incurred due to suboptimal route traversed by the packets from a Correspond...

We present an approach to network forensics that makes it feasible to trace the content of all traffic that passed through the network via packet content fingerprints. We develop a new data structure called the “Rolling Bloom Filter” (RBF), which is based on a generalization of the Rabin-Karp stringmatching algorithm. This merges the two key advantages of space efficiency and an efficient conte...

In this work, we performed variety of tests to see the effects of network loads and latency in multiplayer online games. We applied hierarchical load testing architecture using large scale virtual clients to find out the bottlenecks of the game servers. We also investigated the effect of latency on multiplayer online games. We controlled network game packets (i.e. packet delay, packet drop rate...

Network coding in Mobile Ad hoc Network (MANET) is well-known in reducing delay, increasing throughput, and improving transmission reliability. While the data throughput capacity of MANETs is unknown, the scaling of capacity with the number of nodes has recently received increasing attention. This paper proposes a Complex Field Network Coding-based Multipath Routing in MANETs (CFNC-MRM). The pe...

We present a network design that provides flexible and policy-compliant forwarding. Our proposal centers around a new architectural concept: that of packet rules. A rule is a simple if-then-else construct that describes the manner in which the network should – or should not – forward packets. A packet identifies the rule by which it is to be forwarded and routers forward each packet in accordan...
