Metro Ethernet aggregation routers for rings and EVPN services

IP Infusion delivers the metro aggregation router: OcNOS-SP preloaded on qualified routers that carry Carrier Ethernet E-LINE, E-LAN and E-TREE over EVPN and VPLS, protect the ring with G.8032 or with SR-MPLS and TI-LFA, and measure each service with Y.1731, under one support contract.

Two ways to protect a metro ring

A metro ring of aggregation routers carries Carrier Ethernet services to the core. OcNOS-SP protects it in one of two designs: a G.8032 Ethernet ring, or EVPN services over SR-MPLS with TI-LFA.

G.8032 Ethernet ring. One ring link is the ring protection link, blocked in normal operation. When a link fails, the ring unblocks it and traffic flows the other way. E-LAN services run over the ring.

Questions about the metro aggregation router.

It collects traffic from business, mobile and broadband access onto a metro ring and hands it to the IP core. OcNOS-SP runs the Carrier Ethernet services, the ring protection and the service OAM on it.
Both run on every OcNOS-SP platform, as separate designs. A G.8032 Ethernet ring blocks one ring protection link in normal operation and unblocks it when a link fails, with E-LAN over the ring. EVPN over SR-MPLS carries E-LINE, E-LAN and E-TREE on segment routing, and TI-LFA sends traffic around a failed link on a precomputed backup path.
EVPN E-LINE, E-LAN and E-TREE over MPLS, single-homed or multihomed, plus VPLS, H-VPLS with LDP or BGP signalling, and VPWS. All run on every OcNOS-SP platform.
Y.1731 delay measurement runs per service over VPWS, VPLS and EVPN, and CFM handles fault management. Frame loss measurement support depends on the service type, so check the OcNOS Feature Matrix for the service and platform you plan.
Yes. EVPN multihoming dual-homes access on every OcNOS-SP platform. On selected platforms, MLAG dual-homes a node pair into a G.8032 major ring.
The aggregation routers uplink at 100G or 400G and hand traffic to the IP core over MPLS or SR-MPLS. See the IP core page for details on core and peering routers.
