    "abstract": "IP based video production systems must provide high availability characteristics that are similar to today's SDI system including five nines of availability. Without which it will be difficult to migrate live production to IP. This paper compares and contrasts characteristics of SDI routers with that of IP routers and the fault domains of two systems. It also provides example topologies for IP demonstrating flexibility and scale beyond SDI. Various techniques used in IP networks to improve fault detection will be discussed. Network protocols, deployment practices and the use of application level protocols like SMPTE 2022-7 will be analyzed in regard to improving overall system availability. This paper will demonstrate that properly designed and deployed IP networks can provide five nines of availability and the use of application level protocols like SMPTE 2022-7 can improve the overall availability of the system.",
