ABSTRACT:
The use of Protocol Enhancing Proxies (PEPs) and HAIPE encryption has traditionally been mutually exclusive. IP-layer encryption renders the upper layers, such as TCP, unavailable to the PEP. By integrating the IP layer encryption into the modem and using additive or multiplicative increase and decrease signals as bandwidth notification, signaling is provided across the cryptographic boundary to support the use of a bandwidth aware PEP in a network protected by IP-layer encryption.
