Enterprise Multi-Homed Internet Edge Architectures

As Internet bandwidth becomes more affordable, redundancy and load distribution toward multiple Internet Service Providers (ISPs) are now basic requirements for many enterprises. Selecting the appropriate toolset for a specific policy is often an arduous task given the many services and technologies deployed at the enterprise Internet Edge. These challenges present a high degree of operational complexity when implementing and maintaining this type of environment. This session will help participants understand the available technologies and how they can be applied while minimizing operational complexity. The session will highlight key areas including a review of commonly used and emerging technologies (i.e., BGP, PfR, and LISP), common scenarios that illustrate how each technology operates, best practice designs, and an overview of advanced case studies involving multiple technologies/products (i.e., Multiple Firewalls, Multiple Data Centers, NAT/PAT, and IPv6). The session will focus mainly on dynamic and reliable technologies (i.e., BGP, HSRP) and various policy instruments (i.e., prefix length, metric/preference/path/attribute manipulation, and filtering). This session is intended for network architects, designers, and operators who work for enterprises; systems integrators; and small or large service providers. Practical experience with BGP is a prerequisite for attendance. This session is related to Routing and Switching Technologies within the Network Infrastructure and Systems track.
