Quasi Wire

Quasi Wire is a Virtual Private LAN Service (VPLS) which uses Virtual Private Network (VPN) technology. In contrast to layer 2 MPLS VPNs which allow only point-to-point layer 2 tunnels, VPLS allows any-to-any (multipoint) connectivity. It allows geographically dispersed sites to share an ethernet broadcast domain by connecting sites through pseudo-wires.
  
An advantage to using pseudo-wires (PWs) as the underlying technology for the data plane is that in case of failure, traffic will automatically be routed along available backup paths in the service provider's network. VPLS is thus a more reliable solution for linking together ethernet networks in different locations than simply connecting a WAN link to ethernet switches in both locations.
  
What separate Quasar VPLS (using Quasi-Wire Technology) with other similar service providers is multi media. Typically, VPLS providers will use IP network only whereas Quasar can use other network protocol such as GSM, CDMA and PSTN (dial up) as well as IP network.
  
This beneficiary feature of multi media capacity enable flexible implementation on the field. In addition, the usage of GSM and CDMA network will shorten the time needed for the systems to be implemented in the remote locations where other form of network is not feasible.
