Stream Compression

The Stream Compression protocol is specified in XEP-0138 (a Draft Standard of the XMPP Standards Foundation). defines an XMPP protocol extension for negotiating compression of XML streams, especially in situations where standard TLS compression cannot be negotiated. The protocol provides a modular framework that can accommodate a wide range of compression algorithms; the ZLIB compression algorithm is mandatory-to-implement, but implementations may support other algorithms in addition.

The following XML namespaces are used in the context of the Stream Compression protocol:

The following XML schemas are available for the Stream Compression protocol:
