3) SSP (Server-Server Protocol)
The Wireless Village servers are connected with the SSP protocol. This protocol is used both intra-domain and inter-domain communication across different service providers (such as different mobile operators). It is also used for the communication between the Proprietary Gateway and the WV Servers. Similarly to the CSP protocol, the SSP protocol is XML-based.
The SSP connections run over HTTP or HTTPS and between two WV servers, at least two TCP connections are established: one for outgoing requests and the other for incoming requests [16]. The exchange of messages between two WV servers typically takes place in one hop over a direct connection to the other WV server. However, the servers also support routing of the messages according to business and service agreements. There is no automatic discovery of the WV servers; the configuration (connections and possible routing agreements) must take place manually.
