| Abstract: | One of the most important technologies in reliable multicast implementation is how to detect and recover error efficiently and quickly. There are two mechanisms: repeat and error correction. This paper presents a survey on them focusing on their features and applications. Local recovery and scooping strategy are introduced. At last, it discusses some reliable multicast protocols. |
