GENA stands for General Event Notification Architecture.
GENA Base defines an HTTP notification architecture that transmits notifications between HTTP resources. An HTTP resource could be any object which might need to send or receive a notification, for example a distribution list, buddy list, print job, etc. It was defined in Internet-Draft draft-cohen-gena-p-base-01.txt (now expired). HTTP (for HyperText Transfer Protocol) is the primary method used to convey information on the World Wide Web. ...
Internet Drafts (IDs) are a series of documents published by the IETF. They are drafts for RFCs. ...
GENA Base Client to Arbiter provides for the ability to send and receive notifications using HTTP over TCP/IP and administratively scoped unreliable multicast UDP. Provisions are made for the use of intermediary arbiters, called subscription arbiters, which handle routing notifications to their intended destination. It was defined in draft-cohen-gena-client-00.txt (now expired). The Internet protocol suite is the set of communications protocols that implement the protocol stack on which the Internet runs. ...
The User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. ...
History
During July 13-14 1998 the University of California Irvine convened WISEN: the Workshop on Internet-Scale Event Notification. This event brought together a number of experts of various fields and included a presentation on GENA by Josh Cohen of Microsoft. Delgates showcased their event notification architectures and haggled over requirements of the same. Josh's final slide includes the bullet points "GENA is being implemented by Microsoft Products" and "Our wish is to collaborate to agree on a standard. GENA or other, we will comply."
Interest in event notification appears to have waned after 1998 as participants were unable to come to common definitions of what is required for the definition of notification services and protocols. GENA was briefly considered for use in the Internet Printing Protocol but found a niche as part of the Universal Plug and Play (UPnP) architecture. The Internet Printing Protocol or IPP, defines a standard protocol for printing as well as managing print jobs, media size, resolution, and so forth. ...
Universal Plug and Play (UPnP) is a set of computer network protocols promulgated by the UPnP Forum. ...
