Yes, Piscis SD-WAN is purpose-built to coexist with MPLS and legacy WAN infrastructure, enabling a smooth, phased transition without disrupting existing services.
Hybrid WAN Integration:
Piscis SD-WAN supports simultaneous use of MPLS, broadband, 4G/5G, and satellite links. This allows:
- Overlay deployment on top of MPLS without removing it
- Dynamic path selection based on real-time link performance
- Policy-based routing to prioritize critical apps over MPLS and offload bulk traffic to broadband
Legacy Site Interoperability:
For sites not yet migrated to SD-WAN:
- Regional hubs or data centers act as bridge points between SD-WAN and legacy WAN
- Traffic from SD-WAN sites can reach legacy sites via these hubs using traditional routing protocols (e.g., OSPF, BGP)
- No need to reconfigure legacy routers immediately—ideal for staged rollouts
Underlay-Aware Intelligence:
Piscis SD-WAN continuously monitors all underlay paths (including MPLS) for:
- Latency, jitter, and packet loss
- SLA compliance
- Failover readiness
This ensures application-aware routing across both legacy and modern links.
