From CPE management to backbone routing — the standards AcsFlow speaks, on the ACS side and the IPLANS side.
Provisioning, firmware, diagnostics and real-time control of CPEs — TR-069 and USP.
The classic broadband CPE WAN Management Protocol (Broadband Forum). SOAP/HTTP between an ACS and the CPE: auto-provisioning, firmware, diagnostics, connection requests. The workhorse of carrier CPE fleets.
The successor to TR-069. Multi-controller, microservice data model (Device:2), running over MQTT/STOMP/WebSocket/CoAP. Built for IoT-scale and real-time CPE control.
XMPP for NAT-traversed connection requests, plus MQTT, STOMP, WebSocket and CoAP as USP message transports (MTPs).
The IGPs that carry the core and the BGP that connects it to the world.
Open Shortest Path First — link-state IGP. Areas, LSAs, fast SPF convergence. OSPFv2 (IPv4) and OSPFv3 (IPv6).
Intermediate System to Intermediate System — link-state IGP favored in large SP cores. Level-1/Level-2 hierarchy, protocol-agnostic (TLVs), scales to thousands of nodes.
Border Gateway Protocol — the routing protocol of the Internet. eBGP/iBGP, address families (VPNv4/VPNv6, EVPN), route reflectors, policy with communities.
MPLS and Segment Routing for transport; L3VPN, L2VPN and EVPN for customer services.
Multiprotocol Label Switching — label-switched forwarding underpinning VPNs and traffic engineering.
Label distribution: LDP for hop-by-hop LSPs, RSVP-TE for explicit, bandwidth-aware traffic-engineered tunnels.
Source routing with the SR-MPLS or SRv6 data plane — TE without per-flow state, programmable paths, fast reroute (TI-LFA).
RFC 4364: per-customer VRFs, VPNv4/VPNv6 with route-distinguishers and route-targets over MP-BGP. The backbone of enterprise services.
VPWS (point-to-point pseudowires) and VPLS (multipoint Ethernet) to extend L2 across the backbone.
Ethernet VPN with a BGP control plane over MPLS or VXLAN — modern, active-active L2/L3 services for data center and metro.
The foundation of IPLANS' transactional multi-vendor push and live weathermap.
Model-driven configuration over SSH with candidate/commit and rollback — the foundation of IPLANS' transactional, multi-vendor push.
Streaming telemetry and config over gRPC — subscribe to counters at sub-second cadence for the live weathermap and capacity dimensioning.
Ubiquitous legacy monitoring (MIBs, traps) — still used for breadth of coverage across older gear.
