LinkIP Efficiency / Flexibility

LinkSat has developed a suite of innovative solutions that dramatically improve efficiency and performance of wireless and satellite voice and data networks. The two main elements of LinkSat's solutions are the LinkIP bandwidth efficiency router, and LinkSat's patented Scanned Channel Assigned Networking (SCAN) bandwidth manager. Ethernet switch in the sky When combined in a satellite communications environment, these powerful IP networking tools turn the satellite into a virtual Ethernet switch in the sky.

The LinkIP is a highly efficient and flexible satellite networking services platform that was designed to be a highly capable IP transport and routing solution that maximizes satellite bandwidth efficiency.
Although initially designed as a platform for satellite bandwidth management, it has evolved into a feature rich toolset that provides the following:
Powerful IP policy based router – The LinkIP is a multi-port LAN-WAN router that uses a combination of tools from the Linux Advanced Routing and Traffic Control (LARTC) and a customized implementation of the Quagga routing suite.
Pseudo-wire for emulation of point-to-point and bridged network connections.
LinkShrink compression engine – a highly effective and flexible proprietary lossless compression system that is integrated into the router
LinkCast transport – a custom high-efficiency protocol that provides Ethernet multi-destination capability with only a fraction of Ethernet's overhead.
Multiple LAN and WAN interfaces – The LinkIP supports several interface types, including GigE, sync serial, high speed serial, and T1 / E1.

SCAN Solution

SCAN is LinkSat's patented satellite bandwidth management solution. It is a fully automated on-demand satellite bandwidth management tool that utilizes local spectral analysis at each network node to determine availability of bandwidth for set-up of point-to-point and point-to-multipoint satellite carriers. Spectral analysis is employed at all of the satellite network sites (or access terminals) to track carrier activity in a pre-determined segment of satellite bandwidth. Each site in a SCAN network independently monitors carrier activity and, using the spectral activity data, automatically and autonomously makes decisions on when and where to transmit carriers and which receive carriers to acquire within a pre-defined segment of bandwidth.

The main benefits of the SCAN architecture are:
Hub or hubless network topologies possible - analogous to Client / Server and Peer-to-Peer networking
Multiple network architectures supported - STAR, Mesh or Partial Mesh networking, with multiple hubs if needed
Minimal network software and hardware investment needed - allows cost effective deployment of small networks
Distributed processing – network management is distributed throughout the remotes minimizing single point failures
Layer 2 Ethernet switch in-the-sky - enables full multipoint dynamic routing over satellite
Reduced capital costs - improves overall network reliability and eliminates expensive hubs and high start-up costs


Combined Efficiency

These two powerful tools offer service providers and network operators unprecedented efficiency and performance in a satellite IP network.
