Abstract

   Rapidly-varying conditions in a cellular network can cause problems
   for the Transmission Control Protocol (TCP), which in turn can
   degrade application performance.

   This document presents the problem statement and proposes solution
   principles.  It specifies the requirements and reference architecture
   for a mobile throughput guidance exposure mechanism that can be used
   to assist TCP in cellular networks, ensuring better network
   efficiency and enhanced service delivery performance.

   The proposed mechanism can be applied to any content or TCP/IP based
   application content delivery.  This document describes the
   applicability of the mechanism for Intelligent Video Acceleration
   over cellular networks.
