Psefabric vs. SDN - nihole/PSEFABRIC GitHub Wiki

• SDN approach.

• PSEFABRIC approach.

For simplicity, the layers 2 through 4 of Psefabric Management Data Flow Model are represented by one element "Demultiplexer & Configuration Layers" and layers 5, 6 are labeled as "Automation Layers".

• PSEFABRIC approach doesn't add any additional points of data flow failure. Data never flow through high layers (1 - 6) of PSEFABRIC.
• The PSEFABRIC, as well as the SDN solution has a single point of management.
• In the case of PSEFABRIC we don't need to use new equipment. We may use different automation methods for integration of our old network in a new paradigm.
• PSEFABRIC itself does not allow you to scale Control Plane, but if it is necessary you may use any solution (network fabric or sdn) as part of PSEFABRIC.
