Understanding Challenges in Modern WAN Transport vs. The OcNOS Approach

 

Challenges in Modern WAN Transport
Exploding Complexity
Managing disparate operating systems across different network segments is a constant headache.
Slow Innovation
Rigid systems make it difficult to deploy new services quickly or adopt modern technologies.
Scaling Issues
Meeting the demands of 5G, AI/ML, and IoT requires infrastructure that can scale rapidly and cost-effectively.
High Costs
Vendor lock-in drives up hardware costs and limits your negotiation power.
The OcNOS Approach
Unified & Future-Ready
OcNOS offers a single, consistent OS across your entire WAN (Access to Core), designed for 5G, AI, and IoT. It decouples software from hardware, running on diverse whitebox platforms.
Operational Efficiency
Simplify management, training, and troubleshooting with one unified OS.
Accelerated Innovation
Quickly deploy modern features like SR-MPLS, EVPN-MPLS, EVPN-SR, EVPN-VXLAN, and 400G ZR+ on open platforms.
Reduced TCO, Flexibility & Modular Licensing
Break vendor lock-in, leverage competitive hardware, and gain deployment flexibility. OcNOS offers modular SKUs (SP-IPBASE, SP-MPLS, CSR, and SP-PLUS) with perpetual licensing, so you only pay for features you need, avoiding unnecessary cost or software bloat.

OcNOS Key Software Capabilities for Modern WANs

OcNOS integrates advanced, carrier-grade features essential for building agile, efficient, and future-ready WAN transport networks:

    • Modern VPN Tunneling Technologies: Enables sophisticated traffic engineering, network slicing, and simplified control planes for enhanced automation and service delivery.
Attribute Traditional MPLS SR-MPLS EVPN-MPLS EVPN-VXLAN EVPN-SR
Underlay IP MPLS MPLS IP (VXLAN) SR-MPLS
Overlay MPLS (L2/L3 VPNs) MPLS (L3VPN, L2VPN) EVPN EVPN EVPN
Primary Use Cases L3VPN, L2VPN (VPLS, VPWS), Traffic Engineering L3VPN, L2VPN, Traffic Engineering, Service Chaining L2VPN (ELAN, ETREE, EVPN VPWS), L3VPN integration Data Center Interconnect (DCI), L2/L3 overlay over IP fabric L2/L3 VPNs over SR-MPLS fabric
Key Characteristics Relies on LDP/RSVP for label distribution; stateful per tunnel; established over decades. Based on source routing; uses MPLS labels for SIDs; leverages IGP (OSPF/IS-IS) for prefix/adj SID distribution; stateless from transit nodes. Unifies L2/L3 VPNs; uses BGP EVPN AFI/SAFI; leverages MPLS tunnels for transport; provides active-active multihoming. Unifies L2/L3 VPNs; uses BGP EVPN AFI/SAFI; leverages VXLAN tunnels for transport; ideal for IP-centric networks (e.g., data centers). Combines the benefits of EVPN’s control plane with SR-MPLS transport; uses BGP EVPN AFI/SAFI over SR-MPLS tunnels.
Benefits Mature, widely deployed, robust TE capabilities (with RSVP). Simplified control plane (no LDP/RSVP in core), improved scalability, easier TE. Unified control plane for L2/L3, simplifies DC/WAN interconnect, active-active multihoming. Seamless L2/L3 extension over IP, integrates well with cloud environments, active-active multihoming. Unified L2/L3 control plane, leverages SR-MPLS benefits (simplification, TE), active-active multihoming.
  • Integrated 400G ZR/ZR+ Optics: Optimizes DCI and Metro networks by allowing direct router-to-router connections over significant distances using standard coherent optics, simplifying deployments and reducing reliance on separate DWDM systems.
  • Precise Timing (SyncE/PTP): Meets the stringent timing requirements of 5G and other time-sensitive applications with industry-standard synchronization protocols.
  • Carrier-Grade Reliability & Resiliency: Built for demanding service provider environments with robust routing protocols, fast convergence, in-service software upgrades, and hardware redundancy support.
  • Open APIs & Telemetry: Full support for industry-standard interfaces like NETCONF/RESTCONF, OpenConfig YANG models, and streaming telemetry (gNMI) for deep integration into modern orchestration, automation, and monitoring platforms.
