What Has Come in the Past

§ Whole spectrum of approaches

§ Parallel §  Leveraging similar gear to production data path §  Consistent interface, support and sparing §  Pricy

§ “On the cheap” §  Lower class of device then production data path §  Different interface, sparing, and support §  Inexpensive


Out-of-Band Network Requirements

§ Highly Available Designs §  Redundant uplinks §  Small routing domains §  “Finding” hosts easy at-least to a rack level

§ Best Effort Designs §  Flat Layer-2 design §  STP for loop avoidance, LAG in some newer

deployments §  “Finding” hosts can be hard
