Performance Enhancement Proxies (PEP)

The turboIP® Performance Enhancement Proxies (PEPs) were designed to combat the inherent challenges of transmitting TCP over satellite links.

The units provide transparent acceleration of TCP sessions, increasing throughput over satellite links while requiring minimal topology changes. The Performance Enhancement Proxies support the Space Communications Protocol Standard Transport Protocol . They provide reliable connection-oriented, end-to-end data transfer for user applications. The turboIP units can also overcome the deficiencies that exist with TCP, including slow start and congestion control. The PEPs can be integrated into existing networks in a staged manner, avoiding the need for network-wide upgrades. Typical deployments are by government and military agencies with large or evolving satellite bandwidth requirements for Internet traffic and to support Internet backbone trunking services.

Vipersat Network Products - Bandwidth & Capacity Management

Establishing and managing vital secure communication networks is easy with our feature-rich bandwidth and capacity management products. The Vipersat Network Products integrate with our satellite modems to provide a seamless IP-based infrastructure for satellite networking. The solution is based on dynamically managed Single Carrier Per Channel (dSCPC) and automatic application switching technologies. All aspects of the satellite network can be configured, controlled and monitored by VMS. Our solutions increase satellite network efficiency and provide real-time, interactive connectivity.
