Switched Mesh Network

SkySwitch provides Switched Mesh connection as required in many telecom applications. A Switched Mesh Network as offered by SkySwitch has the following advantages:

  • Self healing - Communications are not affected by failure of nodes
  • Low latency and bandwidth using continuous wave carriers without TDMA framing overhead
  • Single hopping mandatory in all wireless connections
  • Dynamic and static traffic routing
  • No costly hardware

Wireless Mesh satellite network mainly comes in two flavors, Switched Mesh and Shared Mesh.  Switched Mesh uses multiple links (carriers) to connect with neighboring nodes in the mesh.  Here all of the available bandwidth of each separate link is dedicated to neighboring nodes.  Each dedicated mesh link is on a separate channel, ensuring that forwarded traffic does not use any bandwidth from any other link in the mesh.  As a result, a Switched Mesh is capable of much higher capacities and transmission rates than a Shared TDMA Mesh and grows in capacity as nodes are added to the mesh network.

In Shared Mesh network multiple remotes shares a single TDMA carrier to communicate to all neighboring nodes in mesh. Total bandwidth of these links (carriers) is shared among all neighboring nodes in the mesh. The capacity of a remote's channel is further consumed by traffic being forwarded between other nodes, which reduces end-to-end traffic that can be passed for every remote node. Because bandwidth is shared amongst all nodes in the mesh, and because every link in the mesh uses additional capacity, this type of network offers much lower end to end transmission rates than a Switched Mesh network and degrades in capacity as nodes are added to the mesh network.

SkySwitch is a Switched Mesh network with centralized network control server and terminal with integrated modem and router.  SkySwitch routes network traffic to proper destination via dedicated channels selected by IP routing algorithm.  The benefit of using such direct IP routing to provide multiple access services is to maintain a single and 100 percent IP platform throughout the entire network for better bandwidth efficiency and integration with external IP networks.  Satellite Shared TDMA Mesh implementation usually involves routing IP packets over separate time slots on a single shared link to allow multiple access by remotes. The additional layer of TDMA multiplexing is entirely unnecessary in today's IP routing network.
