Couple this with possible environmental variables and sometimes asymmetrical bandwidth conditions, the quality of service in satellite communications is sometimes lacking.
XTP addresses these issues in a variety of ways such as a Selective Retransmission algorithm that deals with loss recovery.
As stated, XTP also provides rate control in which the maximum bandwidth can be specified as well as what size burst data can be accepted.
XTP also offers a reliable multicast protocol, and the flexibility to match any specific application needs.
XTP is a real-time option at Layer 4 for the US Navy SAFENET LAN Profile.
