Routing Consistency

Routing consistency refers to the ability of network paths to remain stable enough for applications to experience predictable latency and packet delivery. In hosting environments with low-latency workloads, frequent route changes can be as disruptive as high average latency because jitter and path asymmetry create irregular application behavior.

UltraVM routing policy emphasizes controlled failover and measured traffic engineering changes. When upstream behavior shifts, operators evaluate convergence impact, packet-loss side effects, and route persistence before applying new path preferences.

Redundancy planning is treated as a continuous process rather than a static topology diagram. Effective redundancy requires periodic validation of failover behavior and documentation of path quality under degraded conditions.
