Cloud DCs). It examines the approach of using SD-WAN to utilize multiple underlay networks by different providers to maximize or optimize interconnection among branch offices, on-premises DCs and Hybrid Cloud DCs. This document also describes some of the (network) problems that many enterprises face when they have workloads \& applications \& data split among hybrid data centers, especially for those enterprises with multiple sites that are already interconnected by VPNs (e.g. MPLS L2VPN/L3VPN) and leased lines. Current operational problems in the field are examined to determine whether there is a need for enhancements to existing protocols or whether a new protocol is necessary to solve them.}, }
