Monitoring is supported on the following service classes: IPv4 and IPv6: [service status, input errors and output drops on physical interfaces] end-user site backbone interface IP Multicast Beacons [service status] Routing protocols: OSPF [link costs] BGP [peering status, adv/rec routes] SDH/Sonet [SDH/Sonet errors] router interface on leased-lines Lambda [service status, optical equipment port status] MPLS [MPLS LSP status] E2E: [E2E service status] defined as the stitching of multiple intra-domain and inter-domain links Statistics services GINS stores performance measurements data and provides: Traffic Statistics IPv4 and IPv6, Multicast for end user sites and backbone Aggregate Peering Premium IP Uncompressed Statistics Sonet/SDH errors on leased lines Router CPU load and temperature Other services GINS includes a Trouble Ticket System which is highly customized for the GARR operations pr
