Sponsored by the National Science Foundation15GENI Introduction – 22 June 2014www.geni.net Compute Layer Examples In-network processing and aggregation of sensor data: –sensed data from vehicles and other in-field sensors can be aggregated in the network by a compute layer service explicitly requested by the originator of the sensed data, thus reducing load on a centralized server. Dynamic binding for Context GUID: a local context defined as ‘unoccupied cabs in location X’ can be named using a GUID and resolved dynamically by an in-network compute layer service pulling information from a dispatch service to determine what end points qualify for delivery request messages.
