Abstract

This document describes the Asynchronous Layered Coding (ALC) protocol, a massively scalable reliable content delivery protocol. Asynchronous Layered Coding combines the Layered Coding Transport (LCT) building block, a multiple rate congestion control building block and the Forward Error Correction (FEC) building block to provide congestion controlled reliable asynchronous delivery of content to an unlimited number of concurrent receivers from a single sender.

Abstract

   This document describes the Asynchronous Layered Coding (ALC)

   protocol, a massively scalable reliable content delivery protocol.

   Asynchronous Layered Coding combines the Layered Coding Transport

   (LCT) building block, a multiple rate congestion control building

   block and the Forward Error Correction (FEC) building block to

   provide congestion controlled reliable asynchronous delivery of

   content to an unlimited number of concurrent receivers from a single

   sender.
