 Pseudo Content Delivery Protocol (CDP) for Protecting Multiple Source
                         Flows in FEC Framework
                   draft-ietf-fecframe-pseudo-cdp-04

Abstract

   This document provides a pseudo Content Delivery Protocol (CDP) to
   protect multiple source flows with one or more repair flows based on
   the FEC Framework and the Session Description Protocol (SDP) elements
   defined for the framework.  The purpose of the document is not to
   provide a full-pledged protocol, but to show how the defined
   framework and SDP elements can be combined together to design a CDP.

1.  Introduction

   The Forward Error Correction (FEC) Framework (described in [RFC6363])
   and SDP Elements for FEC Framework (described in [RFC6364]) together
   define mechanisms sufficient enough to build an actual Content
   Delivery Protocol (CDP) with FEC protection.  Methods to convey FEC
   Framework Configuration Information (described in
   [I-D.ietf-fecframe-config-signaling]) on the other hand provides the
