2. 2 What is the Motivation: Problem Quake UUUU Doom UUUU Every path needs to be optimized. Every game provider needs to provide their own server.

3. 3 What is the Motivation: Solution Do not need to set up your own game servers, just go to an expert in this area Some of these servers would have a good connection to you Connect to a game and get the best server to you Quake Doom U U U U Quake Doom U U U U Quake Doom Quake Doom Overla y

5. 5 Overlay Abstraction Goal: provide a scalable, extensible, and accurate interface to network management. How: Scalability: Aggregate capability advertisements; multicast invocations and content Extensibility: XML-based query-response Accurate: Can trade off between accuracy and overhead based on application semantics

7. 7 Gaming Provider – The Functional Indirection Point The gaming provider runs her code on various nodes on the resource overlay. The gaming provider, in essence, enables the control path and hence, the application. The gaming provider is responsible for: Maintaining a well-known portal for users to “join”. Having bilateral agreements with the resource providers, profile managers, measurement infrastructure etc. Load balancing based on user importance, profit margins, etc. Making the decision to spawn new resource nodes. Maintaining “QoS” of users based upon various factors.

There might be local clustering algorithms amongst the nodes in the resource overlay. The resource overlay may consist of a code distribution overlay that migrates code to each node in the other component, the processing overlay.

9. 9 Interconnecting Heterogeneous Networks Gaming environment is abstracted away through a gaming API. Network specifics are also abstracted away. Example: Sensor network Data gathering node must conform to API and records/transmits gaming state accordingly. Data Gathering Node Gaming Provider
