Abstract:
1. A method of communicating in a communication system having a first network having a first host sourcing plain text information and a second host receiving plain text information over TCP connections, and a second network for encrypting the plain text information between the first and second host, comprising the steps of: (a) monitoring an available bandwidth of a satellite network in the second network via a satellite link at a bandwidth agent located in a satellite modem in the second network using a satellite congestion protocol and determining a bandwidth adjustment parameter from monitoring the available bandwidth; (b) formatting an IP encrypted message containing the bandwidth adjustment parameter using an ECN (Explicit Congestion Notification) protocol containing bits representing different levels of signaling by the satellite modem; (c) transmitting the formatted message from the second network to a performance enhancing proxy (PEP) in the first network via an IP decryption device; (d) translating a message formatted for the first network to a format for the second network by the PEP as a function of the bandwidth adjustment parameter, wherein the bandwidth adjustment parameter is used by the PEP to determine the available bandwidth for the satellite network in the second network.
