To understand the bandwidth savings of using a GUP it is important to understand the amount of traffic generated by definitions updates. When should a Group Update Provider be used? This is to insure that definitions are available to the client even if GUPs are unavailable. If the client is not able to download the definition from the GUP due to the amount of time it takes or if the GUP is unavailable, it will then default to pulling definitions from the SEPM. On the next heartbeat interval the client will then download the definition from the GUP. If the GUP does not have a definition it will reach out to its defined SEP Manager and download the correct update. In an environment where a GUP is configured, clients designated to use GUPs will reach out on port 2967/TCP to see if there is a definition update available. The GUP technology in SEP allows administrators to designate client systems within the environment to distribute client definitions in a peer fashion. In this article we wanted to explore what a GUP is, how they can be useful, and proper implementation.
