An evaluation of priority consistency in protocol architectures
نویسندگان
چکیده
Workstations for digital audio and video applications must support predictable processing, presentation, and transmission of continuous media data while making efficient use of limited hardware resources. We present techniques for managing network resources and processing messages in a predictable fashion. Our solutions use a novel structure for the protocol processing software, and we examine several alternatives and discuss the engineering tradeoffs associated with each. Using simulation, we evaluate our protocol processing structures and show that the more sophisticated structures can improve the response time and predictability of time-constrained messages. The ideas presented in this paper can be applied to resource management in the operating system and to the structuring of application-level servers. The designers of gateway machines (for internetwork routing) which handle both timeconstrained traffic and non-time-constrained traffic may also benefit from this study.

Making a DSM Consistency Protocol Hierarchy-Aware: an Efficient Synchronization Scheme
We consider the design of DSM consistency protocols for hierarchical architectures. Such architectures typically consist of a constellation of loosely-interconnected clusters, each cluster consisting of a set of tightly-interconnected nodes running multithreaded programs. We claim that high performance can only be reached by taking into account this interconnection hierarchy at the very core of...
متن کاملReliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

This paper presents the AAected Set Priority Ceiling (ASPC) concurrency control protocol for real-time object-oriented databases. The protocol is based on a combination of a semantic locking technique and priority ceiling techniques. The paper speciies six criteria for real-time concurrency control: high concurrency, deadlock prevention, predictability, temporal consistency enforcement, logical...

Computer architects are now studying a new generation of chip architectures that may integrate hundreds of processing cores and memory banks on a single chip with novel interconnect technologies. A key challenge lies in the design and development of an efficient on-chip shared memory organization for these future many-core architectures. New approaches need to be developed to address this chall...
متن کاملVeri cation of FLASH Cache Coherence ProtocolBy Aggregation of Distributed Transactions
To verify cache coherence protocols for distributed multi-processor architectures, we compare a state graph of the implementation with a speciication which is a state graph representing the simpliied behavior. The steps in the spec-iication correspond to atomic transactions, which are not atomic in the implementation. The method relies on an abstraction function which aggregates the implementat...
