Off-line and on-line guaranteed start-up delay for Media-on-Demand with stream merging

Amotz Bar-Noy, Justin Goshi, Richard E. Ladner
2006 Journal of Discrete Algorithms  
We address the problem of designing efficient algorithms for media-on-demand in systems that use stream merging.  ...  We construct an efficient O(n) optimal off-line algorithm for a time horizon that is composed of n time slots, where the length of one slot is the guaranteed start-up delay.  ...  Introduction Media-on-Demand is the demand by clients to playback, view, listen, or read various types of media such as video, audio, and large files with as small as possible start-up delay and with no  ...

Efficient Algorithms for Optimal Stream Merging for Media-on-Demand

Amotz Bar-Noy, Richard E. Ladner
2004 SIAM journal on computing (Print)  
We address the problem of designing optimal off-line algorithms that minimize the required bandwidth for media-on-demand systems that use stream merging.  ...  We concentrate on the case where clients can receive two media streams simultaneously and can buffer up to half of a full stream.  ...  Introduction Media-on-Demand is the demand by clients to playback, view, listen, or read various types of media such as video, audio, and large files with as small as possible startup delays and with no  ...

The Dyadic Stream Merging Algorithm

E.G. Coffman, Predrag Jelenković, Petar Momčilović
2002 Journal of Algorithms  
We study the stream merging problem for media-on-demand servers. Clients requesting media from the server arrive by a Poisson process, and delivery to the clients starts immediately.  ...  The dyadic algorithm and the best on-line algorithm of those recently proposed differ by less than a percent in their comparison with an off-line optimal algorithm.  ...  In this setting, the algorithm of this paper has the properties: • It is on-line; i.e., the media server does not know arrival times in advance. • It gives a zero-delay guarantee; i.e., all video requests  ...

Cost- and QoS-Efficient Serverless Cloud Computing [article]

Chavit Denninnart
2020 arXiv   pre-print
For the second approach, we developed the mechanisms to skip tasks whose chance of completing on time is not worth pursuing by drop or defer them.  ...  We dynamically adjust such thresholds based on multiple characteristics of the arriving workload and the system's conditions.  ...  Evaluating streaming start-up delay: To evaluate the streaming start-up delay, we measure the end-to-end time from when the stream request arrives in the system to the time that the first segment is delivered  ...

Algorithms for interference sensing in optical CDMA networks

P. Kamath, J.D. Touch, J.A. Bannister
2004 2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577)  
Nodes defer transmissions if there is interference on the line, thereby improving network throughput. We discuss and analyze three algorithms for interference sensing.  ...  Interference Sensing is a media access architecture where nodes on the network sense the amount of interference on the line before transmission.  ...  It tries to ensure that the interference between codes on the line is minimal and that media access delays are kept within bounds.  ...

Multimedia Networks and Communication [chapter]

The reason for this is that the collisions, which occur in the bus-based Ethernet if two stations start sending data on the shared line at the same time, lead to delayed service time.  ...  Their delay-dependency is significantly diminished by having an adaptive buffer at the receiver that downloads and stores a certain portion of the media stream before starting playout.  ...

A CORBA-based quality of service management framework for distributed multimedia services and applications

J.W.-K. Hong, Jong-Seo Kim, Jae-Kyu Park
1999 IEEE Network  
For distributed multimedia services, it is essential that Quality-of-Service (QoS) is guaranteed system-wide, including end-systems, communication systems and networks.  ...  For validating this concept, we have developed a QoS management system for managing and controlling the QoS of a distributed multimedia system called MAESTRO.  ...  Emerging networks such as ATM [11] and the proposed integrated services with reservations [12, 13, 14] can, up to certain extent, provide guarantees on bandwidth and delay for data transfer.  ...
