OPTIMIZING SATELLITE COMMUNICATIONS WHILE SOLVING PERFORMANCE AND CAPACITY CHALLENGES

With satellite links fast becoming a scarce commodity, Expand’s WAN Optimization solution, with integrated Space Communication Protocol Standard technology, helps distributed organizations overcome the traditional low bandwidth, high latency obstacles that impede the speed and performance of applications and services over satellite links.

It is the complete integration between compression, byte level caching, acceleration, optimization and quality of service in a single appliance that puts the Expand solutions ahead of all the competition.

OPTIMIZING IP TRAFFIC OVER SATELLITE

With the growing demand for remote access broadband services, satellite networks are becoming increasingly popular. In remote and rural areas, where there is little or no terrestrial communications infrastructure, satellite communications becomes the only viable option. Satellite links also provide a unique high-availability option as fail-over links to remote branches. Locations that would like to ensure connectivity in terrestrial network outages are utilizing satellite links to free themselves from those dependencies. Although the TCP/IP protocol is widely used to provide reliable data delivery it has challenges when running over wide area networks. When asked to run over satellite those challenges are exponentially increased. These stem from the inherent characteristics of satellite channels, such as large delays, increased error rates, and bandwidth asymmetry and availability.

ENABLING MOBILE MILITARY COMMUNICATIONS

Military communications networks require superior performance, but mobile networks that incorporate satellite links must contend with at least two performance-killing issues: congestion (because of limited capacity) and poor application performance (because of latency.)

By specifically addressing both congestion and latency issues on satellite links, Expand Networks Accelerators deliver the communications and applications performance that are vital to the military and other users of satellite communications

EXPAND NETWORKS’ ACCELERATOR APPLIANCES RACE PAST THE COMPETITION

Expand Network’s Accelerator WAN Optimization appliances, running the COMPASS Accelerator Operating System, dramatically outperform the competition. In our tests, the Accelerator appliances consistently and reliably sent the most data across high latency, low-bandwidth satellite connections. The appliances compensate for satellite transmission delays, increases both effective bandwidth and throughput and delivers maximum network efficiency.
