With the increasing demand of the big data processing and the personalized services in the Internet, the current service platforms such as cloud are becoming hard to meet the requirement of multiple-level quality of services (QoS) within a short execution time. In this paper, an on-site elastic autonomous service network named SEA is proposed to cope with the above problems by utilizing the available...
In order to evaluate the influence of neighbors' quality to P2P streaming system's performance during scheduling, this paper establishes a markov chain based differential function model to analyze the relationship between peer's average startup delay and probability neighbors have wanted data as well as neighbors' available upload bandwidth. This paper also proposes a scheduling feedback algorithm,...
Reducing server's bandwidth pressure is one of the key problems in the designing of peer-to-peer video-on-demand system. In this paper, we analysis and model this problem via using the “pseudo sequence scheduling”, which is widely used by many peer-to-peer video-on-demand systems. We reveal the relations between the server bandwidth consumption, the cache size and the join speed of peers. This result...
Directed Acyclic Graph (DAG) is a nature way of workflow description. One of the most important and challenging problems in the DAG workflow field is the QoS-constrained scheduling problem with the aim to minimize the cost. This paper proposes a new algorithm to tackle this problem. The algorithm proposed is based on tabu search and make some improvements. Subject to the deadline of the workflow,...
Data scheduling is the key issue in peer-to-peer streaming system, especially in peer-to-peer VoD system. This paper mainly focuses on data chunkspsila priority definition of data scheduling in peer-to-peer VoD system. After carefully studying the meanings of regular rarest first scheduling and random scheduling, a local-rarest-random-heurist (LR2H) scheduling is proposed in order to fully use the...
This paper analyzes the characteristics of time-shifting service for mobile multimedia broadcast and proposes a strategy of resource scheduling for time-shifting proxy server based on predictable user behaviors. Further more, by modeling user behaviors and defining user-habit property, this paper also proposes two different prediction algorithms, the algorithm based on maximum transition probability...
