Security is an important concern in today's networking and particularly in satellite communication, where eavesdropping and active intrusion is much easier than in terrestrial fixed or mobile networks because of the broadcast nature of satellites. Many applications require the security feature of data confidentiality; in order to offer such capability, encryption keys must be constantly changed upon...
In this paper we present SRDP-sign, a reliable multicast protocol designed to guarantee the reliable transmission of short messages via satellite as an extension of satellite reliable distribution protocol (SRDP). The uses of this protocol range from sending short text messages to transmitting information used for the improvement of networkspsila performances. The innovation of this protocol is that...
This paper aims at understanding the behavior of a grid where a multicast network is used for communications. In particular, our attention is focused on a network where the multicast transmission comes mainly from a GEO satellite link. We show the details of a new use of a reliable multicast protocol, SRDP, in the Globus toolkit. Theoretical analysis and results from a real test show that, for a subset...
Satellite links already provide Internet for multicast transmissions over large areas. It would be very useful to extend the traditional use of satellite applications to the management of networks. In this paper we show the evolution of the satellite platform. We then report a novel protocol, the centralized signaling protocol (CSP), which manages signalling messages to routers in terrestrial networks...
The paper defines an architecture that uses the satellite as a communication medium for efficient and reliable large file distribution across WANs, and so disseminate large files at multiple receivers in geographically dispersed grids, exploiting e SRDP protocol
