Some of the key benefits include:
•
Reducing bandwidth consumption
•
Keeping servers behind the FX Series anonymous for security purposes
•
Delivering fast access to content
1.3.8 TCP Optimization
Advanced protocol optimizations drive significant improvements in bandwidth efficiencies and time
savings (reducing payload and latency). WAN optimization and application acceleration technologies are
deployed to improve satellite network performance and increase the amount of applications and users
that can be delivered over the satellite link. The FX Series manages all TCP sessions, and handles the
establishing and tearing down of TCP connections locally (at LAN speeds) to avoid satellite network
congestion problems. This helps to increase link utilization and improve the user experience. TCP
termination offloads the responsibility from servers having to handle the overhead imposed by the
volume of TCP connections from web applications.
Additionally, application level multiplexed TCP streams take advantage of all other TCP or protocol
optimization done at the link level, and application-level handshakes are eliminated by consolidating
transaction requests.
Benefits include:
•
Increases server capacity
•
Reduces the amount of traffic sent over satellite links
•
Keeps the satellite links maximized for optimum utilization
•
Dramatically reduces transaction TCP turns (requests and responses) that bottleneck
satellite links
