Results Results - Communication Interface- Communication Interface
Reason for having two interfaces Functions of Two interfaces design
– Allow implement application programs with EVC++– Allow communication between DMSS and servers
Short interfaces communication time– Less than 3 ms
Easy to extend– Separate application layer and network layer
