This is the first presentation out of 3 on Slideshare reviewing the enterprise needs, issues and considerations from WAN services from CIO point of view. This presentation series is for CIOs and the providers that offer such services. All you need to know about carrier Ethernet service levels and SLAs – what matters to the users and what a service provider should offer. Part I – why chose carrier Ethernet WAN services Part II – Service levels and SLA Part III – Ethernet and IP VPNs – when to use each

1. Carrier Ethernet – The CIO PerspectivePart I: Why Choose Carrier Ethernet WAN Services? RAD Data CommunicationsJune 2011

3. Network connectivity and WAN services must therefore address a new set of challenges:

4. Budget constraints

5. Dynamic business environment

6. Satisfying user expectations

8. 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

11. Familiar, ubiquitous LAN technology – no need for new training

13. Easy to adjust when more bandwidth is required

15. Carrier Ethernet Supports all Enterprise Services VPN Private Line Dedicated Internet Access (DIA) Remote Access Cloud Connectivity

16. 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

17. 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 Check out other installments in the series: Part II: Service Levels and SLAs Part III: Ethernet and IP VPNs, When to Use Which?
