Vulnerability analysis of VoIP network based on NGN to threats of illegitimate signals and media messages

In the article it is presented an analysis of vulnerabilities in voice transmission network via IP. The results are obtained with the help of testing which was carried out at the test bed equipment of one of the Russian communication statements as well as a result of the real situations analysis which have evidences of DoS attack occurred in existing network. For carrying out the tests the are following threats of information security which were subject to simulate: illegitimate signal messages, illegitimate pay load of signal messages, illegitimate media messages.
Key words: NGN (new generation network), threat, Denial of service( DoS), передачи Voice over IP (VoIP), (Session Initiation Protocol( SIP), softswitch, compromise, MG( Media Gateway.)

Aspects of the preventive preparation of the telecommunication networks for the operation under emergency. Part I

In this section, statement of the problem is proposed. It is associated with major aspects of network preparation for usage in an emergency. In normal operation, the network formed by the tuple, the elements which characterize the basic properties of the telecommunications system. When an emergency occurs, the elements of the tuple are changing with the failures and changes in the nature of traffic served.
Key words: emergency, telecommunication system, preventive preparation of the network, traffic, failure.

Stability of the connection in multi-hop mobile networks with the directed signaling

In this work, results of the analytical study and numerical modeling of the antennas direction influence for the frequency of failure of the communication channel in the process of routing in mobile multi-hop wireless ad hoc networks is presented. It is shown that the use of multipath routing allows to raise stability of the connection. Key words: antennas direction, mobile multi-hop wireless, multipath routing allows, stability.
