In this paper, a neural network scheme is presented for modeling VBR MPEG-2 video sources. In particular, three non linear autoregressive models (NAR) are proposed to model the aggregate MPEG-2 video sequence, each of which corresponds to one of the three types of frames (I, P and B frames). Then, the optimal mean-squared error predictor of the NAR model is implemented using a feedforward neura...

Managed Security Service Provider (MSSP) networks are a form of collaboration where several firms share resources such as diagnostics, prevention tools, and policies to provide security for their computer networks. While decisions to outsource security operations of an organization may seem counterintuitive, there are potential benefits from joining a MSSP network due to pooling of risk and acc...

The problems and methods for adaptive control and multi-agent processing of information in global telecommunication and computer networks (TCN) are discussed. Criteria for controllability and communication ability (routing ability) of dataflows are described. Multi-agent model for exchange of divided information resources in global TCN has been suggested. Peculiarities for adaptive and intellig...

The virtualization concept along with its underlying technologies has been warmly adopted in many fields of computer science. In this direction, network virtualization research has presented considerable results. In a parallel development, the convergence of two distinct worlds, communications and computing, has increased the use of computing server resources (virtual machines and hypervisors a...

Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...

A novel distributed-resource abstraction environment is introduced. You can access any resource in a computer network as a memory mapped I/O device, as if it was attached to the local bus of your PC. This network technology gives us several bene ts. From the application development viewpoint, no network-related programming is required, and we don't need to modify the applications even if the ne...
