Abstract: Context information of a handshake between a source entity and a target entity is obtained at a security proxy. The context information is transmitted from the security proxy to a key manager. The key manager maintains a first private key of the security proxy. A first handshake message is received from the key manager. The first handshake message is generated at least based on the context information and signed with the first private key. The first handshake message is then transmitted to the target entity.

Abstract: Apparatus and methods are provided for TCP bufferbloat resolution. In one novel aspect, the TCP client monitors a TCP throughput, determines a TCP throughput stability based on a changing rate of the TCP throughput, adjusts a RWND size dynamically based on the determined TCP throughput stability, and sends the dynamically adjusted RWND size to the TCP server for flow control. In one embodiment, the TCP throughput is stable if the changing rate of an increase or decrease of the TCP throughput is smaller than a threshold, otherwise, the TCP throughput is unstable. The TCP client decreases the RWND size if the TCP throughput is stable, otherwise the TCP client increases the RWND size. In one embodiment, the increase of the RWND size uses the default RWND size adjustment method and the decrease of the RWND size is further depending on the increasing or decreasing state of the TCP client.
