Carrier Ethernet - the CIO perspective - Part I Carrier Ethernet - the CIO perspective - Part I Presentation Transcript

  • Carrier Ethernet – The CIO PerspectivePart I: Why Choose Carrier Ethernet WAN Services?
    RAD Data CommunicationsJune 2011
  • The CIO Perspective
    • Today, communications and knowledge management tools, such as mobility and collaboration, are critical for the enterprise’s success
    • Network connectivity and WAN services must therefore address a new set of challenges:
    • Budget constraints
    • Dynamic business environment
    • Satisfying user expectations
    • Enable remote users/locations
  • Top Priorities for WAN Enterprise Services
    Meet budget constraints by increasing IT operations’ efficiency and productivity, lowering operating expenses
    Distance learning vs. costly on-site training
    Lower price per Mbps
    Help extend (budgetary) planning horizons to avoid expensive overhauls
    Dynamic business environment
    Efficiently handle site additions and bandwidth upgrades
    Quick adaption for new applications
    Fast reaction to organizational changes
  • Top Priorities for WAN Enterprise Services (Cont’)
    Satisfying user expectations
    Ensure user QoE (quality of experience) for critical applications
    Enable speedy fault resolution and performance accountability
    Ensure service resiliency for BC/DR (e.g., for datacenter connectivity)
    Get more bandwidth on-demand
    Enable remote users/locations
    Support distributed communications and Web-based applications for disparate locations, workforce on the move, etc.,
    Ensure system integrity and data security
  • Carrier Ethernet Addresses WAN Enterprise Service Requirements…
    Value – get more for less:
    • Higher throughput at much lower price per Mbps than Frame Relay and other legacy services
    • Scalable rates up to 10 Gbps with guaranteed throughput = Get as much bandwidth as you really need
    Simplicity & Reliability:
    • Mature, standardized technology (Metro Ethernet Forum, IEEE, ITU-T, IETF)
    • Familiar, ubiquitous LAN technology – no need for new training
    • Built-in resiliency features
    • Provides flexible connectivity site-by-site; non-disruptive site addition
    • Easy to adjust when more bandwidth is required
    • Enables IP applications such as MPLS VPN and Dedicated Internet Access (DIA) 
  • …Which is Why Carrier Ethernet Services are Booming
    The fastest growing segment in the telecom industry today
    Coverage spreading from the Metro to global reach
    Need high speed connectivity wherever business is going
    Growing popularity of distributed data centers and cloud services
  • Carrier Ethernet Supports all Enterprise Services
    Private Line
    Dedicated Internet Access (DIA)
    Remote Access
    Cloud Connectivity
  • A Word about Cloud Services Connectivity
    High adoption rate of SaaS, IaaS, PaaS, etc:
    Global spending on cloud computing will more than triple from $37.8 billion in 2010 to $121.1 billion in 2015 (source: Markets & Markets)
    The “First Mile” is key to reaping the benefits of virtualization
    Traffic volumes dictate packet-based high capacity Ethernet links in the access  
    Need priority and performance guarantees end-to-end per application:
    Traffic engineering and CoS/QoS management capabilities throughout the service path
    Security considerations beyond servers:
    Extending MPLS network to the access: has no built-in security or authentication mechanisms. Anyone with an MPLS-compatible access device can tap into the network and inject malicious packets into it
    Carrier Ethernet, on the other hand, offers a wide variety of protection techniques, including exclusive addressing schemes, port protection attributes and dedicated authentication protocols
  • In Conclusion
    Carrier Ethernet is best equipped to meet current and future enterprise communications challenges
    Cost, simplicity and flexibility benefits drive increasing Carrier Ethernet adoption rate
    Most service providers are adding various Carrier Ethernet “flavors” to their WAN service offerings
    Understanding available options can lead to significant cost reductions in WAN communications
