EANTC MPLS SDN Interoperability Test 2023

EANTC published the results of the annual multi-vendor MPLS SDN interoperability test event. The results are showcased live at Upperside's MPLS SD & AI Net World Congress 2023 in Paris. Detailed descriptions of each test and its results are published in our 64-page test report.

More than 80 attendees (onsite and remote) from these 17 vendors teamed up to validate the interoperability and integration of state-of-art telecom transport network technologies.

EANTC designed the interoperability test cases to probe the maturity of transport network solutions to support 5G network services, data center networking evolution, and multi-vendor domain orchestration. The event covered more than 60 test cases evaluated in many multi-vendor combinations, and more than 1,230 test results were achieved. The latest innovations in the following technology areas were covered:


  • IPv6 Unnumbered Underlay and IPv6 VTEP
  • Optimized Inter-subnet Multicast Forwarding (OISM)
  • EVPN-VPWS Seamless Integration
  • EVPN Gateway Interworking

Segment Routing

  • uSID interoperability
  • SRv6 Locator Summarization with uSID
  • SRv6 Unreachable Prefix Announcement (UPA)
  • Inter As BGP Classful Transport
  • SR-MPLS Inter-Domain SR-TE Assisted by BGP-LS


  • Signaling a Colored SR-MPLS and SRv6 Policy
  • PCC-Dynamic Paths Instantiation
  • NETCONF Transport Slicing Controller

Time Synchronization

  • Fronthaul transport tests under O-RAN Specs
  • Calculating limits for chains of Boundary Clocks
  • eSyncE verification
  • PTP over MACsec
