  • Key Issue: What strategies should companies follow to maximize their data center network? Most enterprises rely too much on trusted vendors and make the transition from a traditional vendor relationship to one where the enterprise starts to cede control of the strategic direction for a specific part of their IT architecture. Ceding control enables the vendor to drive its agenda, which often does not fully align with the enterprise's business requirements, despite assuring words from the vendor. In many cases, the vendor is large and often dominant in its space, and it is possible to enable the vendor to exert too strong an influence in the IT organization. Through its controlling influence, the vendor typically will expand its offerings and will affect an increasingly larger portion of the architecture. The net result for the enterprise is a continued loss of control, with an increasing deviation from its true business requirements. In addition, the enterprise will likely pay an increasing premium for this non-optimal solution. The Vendor Influence Curve is a self-assessment model to aid enterprises in their relationships with key vendors. It is especially useful when dealing with very strong or dominant vendors in a particular marketplace or major element of IT. The Vendor Influence Curve is a five-level model overlaid on a two-dimensional axis where the vertical axis shows the value to the enterprise and the horizontal axis shows value to the vendor. The value to the enterprise peaks when the enterprise is at Level 3 on the Vendor Influence Curve. As the vendor influence increases beyond Level 3, the value to the vendor continues to rise, but the value to the enterprise drops. Understanding the balance between the buyer (the enterprise) and the seller (the vendor) provides tremendous advantages for enterprises that use the Vendor Influence Curve.
  • The benefits associated with delivering “any service to any device” places even more demands on Carrier Ethernet networks. No longer can services be delivered over dedicated networks, but rather, to maximize efficiency and profitability, all services need to be delivered over a common, flexible, intelligent network. As a result, the following characteristics must be pervasive throughout the network: Resilient: able to handle the increased scale and availability requirements Integrated: able to provide the flexibility to deliver all services and future new services efficiently over a single network Adaptive: able to adjust to the changing demands and requirements that the applications may place on it. These define the carrier principles for what we call “service oriented infrastructure”
  • SDH and its optical layer is the most widespread transport technology TDM, circuit based Carriers extended "smoothly" their circuit networks with packet transport capabilities 802.3, ESCON, FC… interfaces for link connection SDH next gen for packet services to circuit network adaptation bridges features for any-to-any connections Carriers have a large panel of transport solutions current solutions : IP/MPLS, bridged Ethernet new trend : provide tunneling… … with PBB-TE , VPLS , T-MPLS … Connection Oriented wave to " carry " Carrier Ethernet services Similarly to circuit (SDH) technologies
  • Why Ethernet Services ? Enterprises don’t want Carriers to know or route their IP addresses for site-to-site interconnections (VPNs) Ethernet enables Carrier’s network to transport and switch Enterprise IP traffic without interacting with Carrier Ethernet Terminology invented by the MEF to qualify Ethernet Services E-Line (P2P EVC between 2 UNIs) E-LAN (MP2MP EVC between >2 UNIs) E-tree (P2MP EVC between root and spoke UNIs) These services can be delivered over different types of networks (a.k.a "Transport network") Native Ethernet based (802.1, 802.3) Existing Packet transport networks (IP/MPLS) Existing TDM transport networks (SDH-NG, OTN)
  • Commence from the bottom up 802.3ah for local link monitoring 802.1ag for hierarchical service connectivity verification Y.1731 for end-to-end service performance monitoring Saying all that, all these standard have some duplicate capabilities in the fault and connectivity areas.
