FUTURE NETWORK Clause Samples

FUTURE NETWORK. The AVANGRID WAN Network must be a NERC CIP Version 5 compliant operational telecommunications system with the following specifications • Highly scalable, end-to-end solution • High availability and reliability • Robust synchronization • Equipment shall be hardened to utility requirements • Secure – Meets NERC CIP recommendations • Future-proof capabilities • Evolution to SDN • Integrate all AVANGRID services onto single network for cost/operational efficiencies As mentioned before, some selected legacy TDM systems still need to be supported during the migration period. These systems will be combined with high bandwidth packet-based services on a converged transport network. The solution will use a DWDM transport core with a full IP/MPLS network overlay, from AVANGRID Networks locations to Data centers. Legacy TDM and associated traffic (e.g. SONET) will be transported directly over the new DWDM optical infrastructure and the IP/MPLS backbone. Traffic will be carried using several types of VPN services such as: • VLL point-to-point service for traditional TDM, Ethernet, and non-IP services using PWE3 pseudowires. • VPLS point-to-multipoint service allowing transparent transport of data at Layer 2, to minimize complexity. • VPRN • IP multicast delivery. IP/MPLS traffic will be carried over a transport network which is composed of: • A DWDM fiber optic infrastructure based on dark fiber (leased from local carriers) connecting various locations, • A DWDM fiber optic infrastructure based on fiber optic cables owned by AVANGRID • Ethernet leased lines (e.g. 10 Gbps) A network management system (NMS) including fault analysis, performance management, provisioning of network and network devices, maintaining the quality of service will be implemented to give a 360-degree view of the IP/MPLS network.
