| 摘 要： | 在对SIP信令进行动态压缩的过程中,需要使用大量的状态内存空间来存储状态信息,造成状态内存的极大浪费。提出用于SIP信令动态压缩的结构化动态字典设计方案,并结合LZSS算法设计一种基于动态字典的SIP压缩机制,改进SIP信令压缩。实验结果表明,该压缩机制在一定程度上降低了压缩算法的时间复杂度,并实现了状态内存的高效利用。

| Abstract: | A large amount of state memory is consumed when using dynamic compression in SIP signaling compression, which is a great waste of state memory. This paper proposes an effective solution based on structured dynamic dictionary for SIP signaling dynamic compression, and a SIP compression mechanism based on dynamic-dictionary is designed for improving SIP signaling compression combined with LZSS algorithm. Experimental result shows that the new mechanism reduces the time complexity of compression algorithm to some extent and makes effective use of state memory. |
