US Patent 8966123 Unobtrusive content compression in a telecommunications network

A telecommunications network policy enforcing point operable to route IP datagrams in a two-way communication between a first endpoint in a telecommunications network and a second endpoint in the telecommunications network and operable to compress, in accordance with a data compression policy, IP datagrams of a response transmitted by the second endpoint to the first endpoint. The response is of a layer 7 protocol that supports compression, a layer level being an Open Systems Interconnection, OSI, layer in an OSI Reference Model, and each IP datagram of the response comprises a sequence of bytes of data and a header defining a sequence number of the first byte of data in the IP datagram.
