According to my recent study on Smart Grid and the Report to NIST on the Smart Grid Interoperability Standards Roadmap (2009-08-10) published by EPRI, I summarised the following characteristics for the network traffic between Service Provider domain and Customer domain.

1. Nearly real-time

2. Small-size package

3. Large amount of clients

4. Asynchronous messaging

5. Connection-based messaging

6. Secure messaging

7. Broadcast and multicast when required
