SyncSwitch is designed as a highly scalable soft switch with Linux Virtual Server (LVS) cluster and Heartbeat package – world’s famous technology for load balancing and failover for assuring High Availability, Failover and Load Balancing requirements found in carrier-class environments. High-Availability ensures the availability of the service 99.999%. Failover ensures that if any call fails from any switch node after sending to that, it will be redistributed towards other server nodes and get connected. Load Balancing ensures proper distribution of traffic among all server nodes to ensure high performance and premium quality of service. Fault Tolerance that if any server node misses its heart beat or goes down for any reason, it will not impact on the whole system, it will be removed from node pool. Whenever it comes back, it will be added to the pool automatically. With clustered network, SyncSwitch can be designed for any number of concurrency.
