Network capabilities of cloud services for a real time scientific application
Found in: 2012 IEEE 37th Conference on Local Computer Networks (LCN 2012)
By Dilip Kumar Krishnappa,Eric Lyons,David Irwin,Michael Zink
Issue Date:October 2012
pp. 487-495
Dedicating high-end servers for executing scientific applications that run intermittently, such as severe weather detection or generalized weather forecasting, wastes resources. While the Infrastructure-as-a-Service (IaaS) model used by today's cloud platf...
 
Planet YouTube: Global, measurement-based performance analysis of viewer;'s experience watching user generated videos
Found in: Local Computer Networks, Annual IEEE Conference on
By Dilip Kumar Krishnappa,Samamon Khemmarat,Michael Zink
Issue Date:October 2011
pp. 948-956
User experience is a very important aspect of user-generated video streaming service such as YouTube. In this paper, we perform a global study of user experience for YouTube videos using PlanetLab nodes from all over the world. We analyze the number of pau...
 
DASHing YouTube: An analysis of using DASH in YouTube video service
Found in: 2013 IEEE 38th Conference on Local Computer Networks (LCN 2013)
By Dilip Kumar Krishnappa,Divyashri Bhat,Michael Zink
Issue Date:October 2013
pp. 407-415
Dynamic Adaptive Streaming over HTTP (DASH) is a new streaming standard which adaptively streams video based on the link bandwidth between server and client. DASH encoded videos are chunked in small segments and each segment can have different representati...
   
GreenCache: augmenting off-the-grid cellular towers with multimedia caches
Found in: Proceedings of the 4th ACM Multimedia Systems Conference (MMSys '13)

Issue Date:February 2013
pp. 271-280
The growth of smartphones combined with advances in mobile networking have revolutionized the way people consume multimedia data. In particular, users in developing countries primarily rely on smartphones since they often do not have access to more powerfu...
     
Cache-centric video recommendation: an approach to improve the efficiency of YouTube caches
Found in: Proceedings of the 4th ACM Multimedia Systems Conference (MMSys '13)
By Carsten Griwodz, Dilip Kumar Krishnappa, Michael Zink, Pål Halvorsen
Issue Date:February 2013
pp. 261-270
In this paper, we take advantage of the user behavior of requesting videos from the related list provided by YouTube and the user behavior of requesting videos from the top of this related list to improve the performance of YouTube's caches. We recommend a...
     
Low-power sub-threshold design of secure physical unclonable functions
Found in: Proceedings of the 16th ACM/IEEE international symposium on Low power electronics and design (ISLPED '10)
By Dan Holcomb, Dilip Kumar Krishnappa, Lang Lin, Prasad Shabadi, Wayne Burleson
Issue Date:August 2010
pp. 43-48
The unique and unpredictable nature of silicon enables the use of physical unclonable functions (PUFs) for chip identification and authentication. Since the function of PUFs depends on minute uncontrollable process variations, a low supply voltage can bene...
