Description: In recent years, Content Delivery Networks (CDN) and Peerto-
Peer (P2P) networks have emerged as two effective paradigms for
delivering multimedia contents over the Internet. An important feature
in CDN and P2P networks is the data redundancy across multiple
servers/peers which enables efcient media delivery. In this paper, we
propose a network coding framework for efcient media streaming in
either content delivery networks or P2P networks in which, multiple
servers/peers are employed to simultaneously stream a video to a single
receiver. Unlike previous multi-sender schemes, we show that network
coding technique can (a) reduce the redundancy storage, (b) eliminate the
need for tight synchronization between the senders, and (c) be integrated
easily with TCP. Platform: |

Description: Base64是网络上最常见的用于传输8Bit字节码的编码方式之一，Base64就是一种基于64个可打印字符来表示二进制数据的方法。可查看RFC2045～RFC2049，上面有MIME的详细规范。
Base64编码是从二进制到字符的过程，可用于在HTTP环境下传递较长的标识信息。例如，在Java Persistence系统Hibernate中，就采用了Base64来将一个较长的唯一标识符（一般为128-bit的UUID）编码为一个字符串，用作HTTP表单和HTTP GET URL中的参数。在其他应用程序中，也常常需要把二进制数据编码为适合放在URL（包括隐藏表单域）中的形式。此时，采用Base64编码具有不可读性，需要解码后才能阅读。(Base64 is one of the most common coding methods for transmitting 8Bit bytecode in the network. Base64 is a method to represent binary data based on 64 printable characters. View RFC2045 ~ RFC2049, there is a detailed specification of MIME.) Platform: |
