Scheduling and Admission Testing for Jitter Constrained Periodic Threads: Discussion and Proof
- …We present new admission tests for periodic real-time threads with explicitly stated deadlines scheduled according to the earliest deadline first (EDF) algorithm. In traditional real-time periodic scheduling, the deadline of a periodic thread is conventionally the end of the current period. In contr…

A Token-based Accounting Scheme for P2P-Systems
- …This paper presents a token-based accounting scheme for decentralized autonomous systems, such as peer-to-peer systems. The scheme uses tokens as proof of resource usage or service usage. Conforming to the peer-to-peer paradigm, the tokens are issued using a decentralized mechanism. Within peer-to-p…
