DENT Guiding Principles

  • Utilize Linux Kernel, Switchdev and other linux based projects as the basis for the solution (without abstractions and overhead)
  • Treat ASIC and Silicon for Networking/Datapath as any other hardware
  • Simplify abstractions, API, drivers and low level overhead that currently exists in these switches and other open software.
  • Unify the community of Silicon Vendors, ODM, SI, OEM, End Users across many verticals.
  • Solve the Networking Operating System challenge for Distributed Enterprise Edge use case and expand into other use cases such as Enterprise Datacenter
