SkyARCS
|
SkyARCS is a modular, scalable, high-performance satellite IP network technology. It is fully compliant to the ETSI/DVB standard DVB-RCS. Due to its ability to support each terminal with up to 2 Mbit/s in the return link it is ideally suited for business applications with a high demand for information exchange of any kind.
ND SatCom's SkyARCS platform allows Service Providers to serve the growing IP business applications markets. Through the application of intelligent algorithms for transponder allocation and IP burst traffic management, SkyARCS is designed to provide optimal network performance whilst guaranteeing minimal cost of ownership.
ND SatCom provides customer tailored solutions using various terminal technologies as well as integrating best of breed application packages.
The SkyARCS solution represents a highly attractive value proposition for Service Providers, Telcos, ISPs and Satellite Operators providing high quality networking services in sectors such as corporate, governmental and SME's.
Main Applications
- Broadband Internet/Corporate Intranet access
- Voice over IP
- Legacy to IP protocol conversion support (e.g. X.25)
- Scheduled IP multicast traffic support
- Media streaming
- Cost efficient data replication/distribution for corporates
- Large data contribution to central location
- Backup network for remotes to central location
- Virtual Private Network (VPN) support
Hub System Overview
The SkyARCS hub consists of the RLSS (Return Link SubSystem), the FLSS (Forward Link SubSystem), the IPTS (IP Traffic System), the IPCS (IP Content System) and Central Hub Management components.In order to offer a carrier-grade system ND Satcom delivers additional Network Management Tools which ease the handling of the system and improve its QoS and efficiency.
