Martini/Kompella Circuits

Martini Circuits

The xconnect psuedowires we configured in the E-Line section, which use targeted LDP sessions, are often referred to as “Marinti circuits.”

Luca Martini, former employee at Cisco, authored RFC4906 which details a method for transporting L2 frames over MPLS using pseudowires signaled through LDP. https://datatracker.ietf.org/doc/html/rfc4906

Instead of calling this some combination of “MPLS pseudowire for a point-to-point service signaled using LDP” people will just say “Martini circuit” or “Martini pseudowire.” It is good to know what this is referring to.

Kompella Circuits

Likewise, Kompella circuits are BGP auto-discovered and auto-signaled pseudowires which we used in E-LAN (VPLS).

Kireeti Kompella, current CTO at Juniper, authored RFC4761 which details a method for using VPLS with auto-discovery using BGP, and VC (virtual circuit) label signaling using BGP.

Just like with Martini circuits, instead of calling this “VPLS using BGP for autodiscovery and signaling of VC labels” people will just say “Kompella circuits.”
