The USRM was designed to meet the scalability, availability, flexibility, and service 

velocity demands of future services. It is referred to as "universal" because it can 

simultaneously support all of the major headend and client interfaces, plus it can be 

flexibly configured to operate in different ways. For example, it can be configured to 

operate as an Edge Resource Manager (ERM), a SDV Session Manager (SDVSM), a 

Video on Demand Session Manager (VODSM), or an integrated combination of all of 

those. 
The following diagram shows a high-level view of the USRM architecture. The top 

row shows the plug-in applications, while the bottom row shows the various 

interfaces. As shown, the USRM is configured as an integrated unit supporting VOD 

and SDV.
