Core CapabilitiesxCTM-FEAT-V10 · REV D
Self-Organizing Topology
Autonomous peer discovery and route redistribution. Zero-touch provisioning of new nodes within 90 seconds of registration.
↑↑
High-Throughput Core
Aggregate 10 Tbps capacity with per-node 400 Gbps interfaces. Line-rate forwarding via ASIC-accelerated data plane.
Extensible Protocol Stack
Modular plugin architecture supports BGP, IS-IS, OSPF, SR-MPLS, EVPN, and custom encapsulations. Hot-swap capable.
Multi-Layer Redundancy
2(N+2) path diversity at every hop. Automatic failover in under 50 ms. No single point of failure by architectural design.
Decentralized Control Plane
Distributed consensus via Raft protocol. Control plane operates independently on each node cluster without central authority.
