Fault Tolerant Service Function Chaining
Milad Ghaznavi, Elaheh Jalalpour, Bernard Wong, Raouf Boutaba, Ali José Mashtizadeh · 2020
Network traffic typically traverses a sequence of middleboxes forming a service function chain, or simply a chain. Tolerating failures when they occur along chains is imperative to the availability and reliability of enterprise applications. Making a chain fault-tolerant is challenging since, in the event of failures, the state of faulty middleboxes must be correctly and quickly recovered while providing high throughput and low latency.
