availabilityalong
Availabilityalong is a metric used in reliability engineering and network design to quantify the end-to-end probability that a defined path remains operational. It captures the likelihood that a task completes from origin to destination, considering the availability of each segment along the route and any redundancies embedded within the path.
The term blends 'availability' with 'along' to emphasize end-to-end coverage. It appears in discussions of service
Calculation: for a serial path consisting of segments i = 1 to n with availabilities p_i, the end-to-end
Applications include end-to-end service level analysis for cloud service chains, content delivery networks, disaster recovery planning,
Limitations include the assumption of independence and uncorrelated failures. Real-world conditions may exhibit correlated risks, shared
