in this paper, we propose a scheme to improve existing ad-hoc on-demanddistance vector (aodv) routing protocol by discovering and maintaining multiplenon-overlapped routes. our routing protocol is a multipath version of aodvrouting protocol that considers only the disjoint path. due to non-overlappingamong paths, when a link breaks in the network, only one of paths is expired. thepresented rout...

We develop algorithms for the design of optical packet-switched networks. These algorithms are aimed at upgrading an existing ber-based, network infrastructure, such as the NSFNET backbone, by using Wavelength Division Multiplexing (WDM) technology. The network architecture employs wavelength-routing optical switches which enable the establishment of all-optical, WDM channels, called lightpaths...

MANEMO is the integration of Network Mobility (NEMO) and Mobile Ad Hoc Network (MANET). A MANEMO node has an interface to both a MANET and NEMO network, and therefore should choose the optimal interface for packet delivery, however such a handover between interfaces will introduce packet loss. We define the steps necessary for a MANEMO handover, using Mobile IP and NEMO to signal the new bindin...

In this paper a network QoS controller is designed. We use the controller to quantification ally control QoS under the random network traffic. The controller is built by min-plus algebra based on network calculus. The controller includes two parts, the lossless fractal regulator and the finite variable storage shaper (FVSS). We can get the arrival curve with the lossless fractal regulator. Then...

The rapid growth of Internet and the fast emergence of new network applications have brought great challenges and complex issues in deploying high-speed and QoS guaranteed IP network. For this reason packet classification and network intrusion detection have assumed a key role in modern communication networks in order to provide Qos and security. In this thesis we describe a number of the most ...

Networked control systems (NCSs) offer many advantages over conventional control; however, they also demonstrate challenging problems such as network-induced delay and packet losses. This paper proposes an approach of predictive compensation for simultaneous networkinduced delays and packet losses. Different from the majority of existing NCS control methods, the proposed approach addresses co-d...

Packet capturing is an important part of a network administrator’s tool-chain. It is often used to “dig down” into the specific traffic traversing a network. Because of this, it is important that a packet capturing method provides a correct view of how the network acts. Thus, a packet capturing platform must be able to keep up with the line-rate of the router it is co-located with; for most ent...

Network immune systems have been developed in many ways but differ with the feature set used and suffer with identifying network threats in efficient manner. We propose a multi feature inference model which uses various parameters of network flow. Unlike earlier approaches, the proposed method infers valuable knowledge from the packet flow and packet details to detect DDOS attacks. The proposed...

This paper contributes a distributed packet controller which reduces queueing to a single stage in two-stage packet switches. Software and neural network based controllers are described. Simulations under a range of traffic conditions for a 1024x1024 switch size shows the simplest architecture has the best performance.

A typical operating environment of a packet switching (store-and-forward) computer communication network is that it is shared by many users with different classes of packets. Packets may be classified in a very general fashion by types of users, messages, applications, transactions, response time requirements, packet parameters such as packet rate and length, and by network parameters such as s...
