Raising the level of abstraction for synthetic biology design requires solving several challenging problems, including mapping abstract designs to DNA sequences. In this paper we present the first formalism and algorithms to address this problem. The key steps of this transformation are feature matching, signal matching, and part matching. Feature matching(More)
TaP is a storage cache sequential prefetching and caching technique to improve the read-ahead cache hit rate and system response time. A unique feature of TaP is the use of a table to detect sequential access patterns in the I/O workload and to dynamically determine the optimum prefetch cache size. When compared to some popular prefetching techniques, TaP(More)
This survey looks at how traditional networking techniques (e.g., caching, traffic shaping, path diversity, and load balancing) have been adapted to address the needs of Internet-based video delivery. The stringent timing and relatively high bandwidth requirements of video traffic are taxing on best-effort networks and many video specific protocols and(More)
— We derive a closed-form expression for the message collision probability in the IEEE 802.3ah Ethernet Passive Optical Network (EPON) registration scheme. The expression obtained, although based on an approximation, shows a good match with simulation results. We use the results of our analysis to compute the size of the most efficient contention window and(More)
The proposed standard for the IEEE 802.3 Ethernet Passive Optical Network includes a random delayed transmission scheme for registration of new nodes. Although the scheme performs well on low loads, our simulation demonstrates the degraded and undesirable performance of the scheme at higher loads. We propose a simple modification to the current scheme that(More)
— Dynamic Bandwidth allocation in Ethernet Passive Optical Networks (EPONs) has been an area of intense research in recent years. Most of the proposed solutions offer clever methods for fair grant sizing, traffic prediction, and prioritized, differentiated services. Barring some work by Kamal et al. and some elements in the scheme proposed by Ma et al., no(More)
