| Summary and Challenges |
Annex J BACnet/IP devices (Annex J to ANSI/ASHRAE 135-1995) are designed to provide the way for BACnet systems to grow beyond building-wide or campus-wide internetworks. Annex J delineates the BACnet Router and the BACnet/IP Broadcast Management Device (BBMD) with Network Address Translation (NAT) to address the issues.
Challenges :
- BBMD devices is limited and none of them explicitly supports NAT which impedes the development of iBMS '
- BACnet BBMD are not robust enough to deal with abnormal traffic, since protocol implementations are vulnerable to malformed packets and various forms of attacks.
- No proper flow control in BACnet/IP to prevent data loss when traffic exceeds data transmission capacity.
- No Security and Authenticity in the current data collection process. It does not encrypt the transmitted data and authenticate the sources.
- BACnet Addendum 135-2012am add a JSON syntax for the common model and the introduction of RESTful Services for Complex Data Types and Subscriptions also throw light on implementation of data aggregation in BACnet router / BBMD.
|
| Expected Outcome |
- Two prototypes for BACnet Blockchain Router and JSON Aggregator
- Draft amendments to BACnet Standard 135 Annex J BACnet/IP devices
- Provide cooresponding technical documents and apply patent (if any)

| Expected Trial Duration |
12 months
