When it comes to transporting its data sets, EEBUS utilises an exceptionally diverse number of transmission channels. A wide variety of IP and other protocols can be used, from cabled IP networks to simple radio-operated narrow-band networks.
Integrating other technologies via mapping
The EEBUS initiative is currently working together with its partners (OCF and Thread – Fairhair in preparation) e.g. on a integrated mapping in order to efficiently combine CoAP constrained devices with SPINE resources in Addition to the TCP/IP Technology most commonly used on the market.
With SHIP, EEBUS provides a TCP/IP-based, encrypted method of transportation.
An IP protocol for SPINE
In order to optimally implement both their own requirements and the strict security requirements of the energy sector, apart from SPINE as a common data model, the members of the EEBus initiative have also developed their own universal IP solution. This IP specification (SHIP = Smart Home IP) is currently in the process of being standardised through DKE and IEC/Cenelec.
SHIP is based on widely used RFCs and also conforms to TR03109 (BSI guideline for secure, encrypted energy networks and Smart Metering). Apart from these characteristics, SHIP also has a great many other advantages: fast identification and discovery via mDNS is possible, efficient reconnection is no problem thanks to TLS session resumption, and WebSockets provide immediate access for authorised web servers through the firewall. This enables a secure TCP/IP-based device interface without brokers or other single points of failure.
