A satellite IP Trunking network provides several remote local networks with access to the Internet (or another type of network) from one single access point to the backbone.  The forward link from the access point to the remote networks is a single shared high speed carrier, while the return channels are individual SCPC carriers.

This type of star configuration is used to provide backbone connectivity to remote ISPs, to private networks, to ships, etc… It is more commonly referred to as backhauling when used to provide network connectivity to mobile phone cells or WiMax access points.

IP trunking networks can also be used to implement private/corporate networks that have a large traffic requirements between a central point and remote offices.

Because satellite is a communication system with very specific constraints, IP Trunking networks over satellite require specific solutions.

These solutions need to address issues such as:

• How to optimize the use of the expensive satellite bandwidth
• How to integrate the satellite part with the rest of the network infrastructure
• How to cope with the satellite delay that affects the performance of protocols such  TCP/IP
• How to guarantee the quality of the service
• How to secure the traffic against unlawful interception

With the Elevation product family,  Newtec offers end-to-end DVB-S2 solutions for star IP networks. Our VCM and ACM implementations provide unprecedented bandwidth efficiency gains, while our IP appliances ensure the best quality and security of the services.
