This session features the Borderless Network Architecture with a focus on WAN design and best practices. The Borderless Network architecture offers an end-to-end design approach for Midsize and Enterprise organizations with key areas of focus including resilient IP forwarding, QoS, mobility, security, and turnkey enablement of voice and rich media services. The cornerstones of the BN design approach are real-world use cases, prescriptive design guidance, and modular architectural components. This session will include the specific design considerations and details of the tested topologies.
The Borderless Network WAN session includes a detailed discussion of the head-end WAN edge and remote site design options for up to 500 remote locations. These options include the use of layer 2 and layer 3 WAN transport models, usage of single and dual WAN links, as well as single/dual router edge topologies. Additionally, Internet VPN as both a backup and primary transport option is discussed.
Design guidance will include IP addressing and routing protocol best practices, QoS for the WAN edge, IP multicast enablement, and interconnection/interoperabilty with other Borderless Network design blocks (LAN, Internet Edge) as well as access to the Data Center. Other key WAN technologies which are integral to the design are DMVPN and GETVPN for data privacy as well as Wide Area Application Services (WAAS) and WCCP for bandwidth optimization. The design also includes models for both centralized and distributed remote site wireless providing mobility for both internal users and guest access.
