Lecture
This lecture covers the concept of reliable broadcast in distributed systems, comparing it with best-effort broadcast and uniform reliable broadcast. It explains the properties and events associated with each type of broadcast, providing specifications and algorithms for reliable broadcast. The lecture also presents detailed algorithms for implementing best-effort broadcast, along with proofs for their validity, no duplication, and no creation properties. Additionally, it discusses the agreement property in reliable broadcast and the importance of uniform agreement in uniform reliable broadcast.
