System Fabric Plane Format Specification


SFP.0 defines the implementation of a System Fabric Plane Format. A System Fabric is a Layer-2 network (e.g. LAN) that has additional protocols implemented in the endpoint nodes such that the collection of these nodes acts together as a system. Note that a System Fabric may be implemented as:

  • a LAN between blades in a backplane
  • a LAN that spans multiple backplanes
  • a private LAN between Rack Mount Servers that form a system
  • any combination of the above

Note that SFP does not aim to be an end-user protocol. It exists only within the confines of a Converged Communications System (e.g. Content Processing Router). The System Fabric Plane (SFP) framework is intended to be a standard way for modules to communicate in Comm Fabric type applications, such as:

  • Routers
  • Wireless Radio Network Controllers (RNCs)
  • Voice over Packet Gateways
  • Media Servers
  • Firewalls
  • Etc. or any combination of the above.

Note that these are all prime candidate applications for ATCA. SFP is a layer that encapsulates many types of application protocols, such as:

  • Internet Protocol Datagrams
  • TDM/Voice (I-TDM)
  • ATM (AAL-1, AAL-2, AAL-5)
  • Wireless SDUs / PDUs (small packets for Wireless applications)
  • Etc.
