在 article 中的过滤器一章(向下滚动 ~50%)关于Remote Call Framework，提到了2种压缩方式:
- ZLib 无状态压缩
- ZLib 状态压缩
它们之间有什么区别？是ZLib相关的还是这些常用的压缩方式？
在搜索时我只能找到有状态和无状态的网络服务。 stateless/ful 属性不是用来描述压缩方法的吗？
最佳答案
来自 Transport Layer Security Protocol Compression Methods :
Compression methods used with TLS can be either stateful (the compressor maintains it's state through all compressed records) or stateless (the compressor compresses each record independently), but there seems to be little known benefit in using a stateless compression method within TLS.
Some compression methods have the ability to maintain history
information when compressing and decompressing packet payloads. The
compression history allows a higher compression ratio to be achieved on a stream as compared to per-packet compression, but maintaining a
history across packets implies that a packet might contain data needed to completely decompress data contained in a different packet. History maintenance thus requires both a reliable link and sequenced packet delivery. Since TLS and lower-layer protocols provide reliable, sequenced packet delivery, compression history information MAY be maintained and exploited if supported by the compression method.
