Core System Deployment

Recall from Day 1’s background of the Core System □ Core System Needed ▪ Support diverse implementations ▪ Extensible, scalable over time

□ Support Diverse deployments ▪ Standalone ▪Collocated ▪Distributed

Core System Deployment

Core System Architecture supports those goals: □ Enterprise Objects like Core Certification

Authority □ Interfaces like Core2Core □ Ability to vary how software is assigned to

nodes

Core #2 provides all services for the area it covers, all by nG, except for the shared area.

Core #1 provides all services for the area it covers, some by nG, some by DSRC.

Overlap requires agreement; Core #1 and Core #2 both provide services. Each service provided by only one Core, except for DSRC users that can get all services from Core #1.

Core System Deployment Activities

1st Steps (take care of the higher risk items) □ Setup the Core Certification Authority to

establish: ▪Governance policies ▪Certification standards and procedures ▪ Security credentials (root CA)

□ Establish the External Support Systems (the CAs and RAs)

Core System Deployment Activities

Incorporate Lessons from Test Bed, Safety/Certification Pilots Work with Standards organizations to

incorporate Core System interfaces into industry standards Begin to work with Deployers to establish

operating agreements What else?

Discussion – Likely Deployers

Who is likely to deploy a Core System? □ States □ Locals □ 3rd Party Data Warehouse Providers □ System Integrator □ Auto Industry May affect how relationships are defined by

the Core Certification Authority
