Google Wave provides federation using an extension of XMPP, the open Wave Federation Protocol. Being an open protocol, anyone can use it to build a custom Wave system and become a wave provider. The use of an open protocol is intended to parallel the openness and ease of adoption of the e-mail protocol and, like e-mail, allow communication regardless of provider. Google hopes that waves may replace e-mail as the dominant form of Internet communication.[2][8][9] In this way, Google intends to be only one of many wave providers. It can also be used as a supplement to e-mail, instant messaging, FTP, etc.
A key feature of the protocol is that waves are stored on the service provider's servers instead of being sent between users. Waves are federated; copies of waves and wavelets are distributed by the wave provider of the originating user to the providers of all other participants in a particular wave or wavelet so all participants have immediate access to up-to-date content. The originating wave server is responsible for hosting, processing, and concurrency control of waves. The protocol allows private reply wavelets within parent waves, where other participants have no access or knowledge of them.
Security for the communications is provided via Transport Layer Security authentication, and encrypted connections and waves/wavelets are identified uniquely by a service provider's domain name and ID strings. User-data is not federated, that is, not shared with other wave providers.
