Overlay Transport Virtualization

This session features a detailed analysis of the architectural aspects, implementation details and deployment benefits behind the Overlay Transport Virtualization (OTV) technology recently introduced by Cisco. The attendees will learn how OTV, an industry first solution, significantly simplifies Data Center Interconnect (DCI) deployments by extending Ethernet LANs between multiple sites over any network, making multiple data centers look like one logical data center. The attendees will learn how OTV is aimed at providing Layer 2 connectivity beyond the Layer 3 boundary while maintaining the scalability, failure containment and operational simplicity that the Layer 3 boundary provides. OTV involves foundational changes to the learning and forwarding principles of traditional VPN technologies. OTV is a "MAC in IP" technology where the MAC address reachability information is conveyed in a control protocol. The OTV architecture is discussed in detail, giving the attendee a clear understanding of the technical aspects of the technology. The multiple benefits achieved by OTV are discussed in detail during the session. Some of the improvement areas examined in the discussion include core transparency, multi-homing, loop prevention, failure isolation, high availability, bandwidth optimization, etc. This session does NOT cover the technical aspects of the traditional Layer 2 VPN technologies such as EoMPLS, VPLS, etc. Target Audience: Those responsible for the Design, Deployment, Operations, and Management of SP, Enterprise and Data Center Networks will find this session informative and useful.
