1 Verizon IPv6 Transition Daniel O. Awduche, MBA, PhD. IP Network Architecture and Design
2 Outline Infrastructure Readiness Verizon IPv6 Professional Services
3 Verizon has made a firm commitment to evolve its global IP infrastructures to support IPv6 while continuing to expand and sustain IPv4 services : Phased adaptation to control rollout risks and costs Present: Accelerated IPv6 Transition Momentum driven by IPv4 address depletion New network capital investments must incorporate IPv6 functionality.
4 Taxonomy of Verizon Commercial IP Networks Verizon IP Networks Wireline Public IP Wireline Private IP Wireless IP Legacy UUNET (Global footprint) AS701, AS702, AS703, AS14551 Global Enterprise Internet Dedicated Access Legacy Verizon (US Footprint) AS19262 Residential FIOS and DSL services PIP (Global footprint) Global Enterprise MPLS VPNS Wireline Commercial IP Networks vbns+ (US footprint) US Government MPLS VPNS VZW IP backbone (US footprint) Wireless IP Services Wireless IP Network
5 Verizon Global Public IP Overview Global facilities-based vertically integrated IP network infrastructure One of the most expansive global Internet backbone networks AS701/ AS19262 AS14551 AS702 AS703 Spectrum of IP communications services for business and consumer markets IPv6 Service Strategy for Global Public IP Initial i Service Goal lis to achieve IPv6 6feature parity with existing i IPv4 4Internet Services. Longer term goal is to offer value added Machine-to-Machine IPv6 services
