      Problem Statement: Bandwidth Aggregation for Internet Access
              draft-zhang-banana-problem-statement-00.txt

Abstract

   Bandwidth aggregation for Internet access can increase the access
   bandwidth and reliability. It has become a desirable network
   function, especially for those Service Providers who operates
   multiple heterogeneous networks.

   This document describes the issues with bandwidth aggregation for
   Internet access. The required network functions to be supported are
   specified. Several candidate solutions had been considered to support
   bandwidth aggregation for Internet access in IETF. These techniques
   are investigated.
