PARCEL: Proxy Assisted BRowsing in Cellular networks for Energy and Latency reduction
Ashiwan Sivakumar,Shankaranarayanan Puzhavakath Narayanan,Vijay Gopalakrishnan,Seungjoon Lee,Sanjay Rao,Subhabrata Sen +5 more
TL;DR: PARCEL splits functionality between the mobile device and the proxy based on their strengths, and in a manner distinct from both traditional browsers and existing cloud-heavy approaches, and results show PARCEL continues to perform well under client interactions, owing to its judicious functionality split.
Proceedings ArticleDOI
Reducing Latency Through Page-aware Management of Web Objects by Content Delivery Networks
Shankaranarayanan Puzhavakath Narayanan,Yun Seong Nam,Ashiwan Sivakumar,Balakrishnan Chandrasekaran,Bruce M. Maggs,Sanjay Rao +5 more
TL;DR: This paper explores page-structure-aware strategies for placing objects in CDN cache hierarchies and presents schemes for identifying these objects and develop mechanisms to ensure that they are served with higher priority by the CDN, while balancing traditional CDN concerns such as optimizing the delivery of popular objects and minimizing bandwidth costs.
Toward Session Consistency for the Edge
Seyed Hossein Mortazavi,Bharath Balasubramanian,Eyal de Lara,Shankaranarayanan Puzhavakath Narayanan +3 more
TL;DR: A distributed datastore tailored for edge computing that provides session consistency between otherwise eventual consistent replicas by tracking and migrating only the clientaffected keys between the replicas.
Proceedings ArticleDOI
NutShell: Scalable Whittled Proxy Execution for Low-Latency Web over Cellular Networks
Ashiwan Sivakumar,Chuan Jiang,Yun Seong Nam,Shankaranarayanan Puzhavakath Narayanan,Vijay Gopalakrishnan,Sanjay Rao,Subhabrata Sen,Mithuna Thottethodi,T. N. Vijaykumar +8 more
TL;DR: Experiments with top Alexa Web pages show NutShell can sustain, on average, 27\% more user requests per second than a proxy performing fully redundant execution, while preserving, and sometimes enhancing, the latency benefits.
Journal ArticleDOI
Karma: Cost-Effective Geo-Replicated Cloud Storage with Dynamic Enforcement of Causal Consistency
Tariq Mahmood,Shankaranarayanan Puzhavakath Narayanan,Sanjay Rao,T. N. Vijaykumar,Mithuna Thottethodi +4 more
TL;DR: Karma is proposed, the first system to enable causal consistency for partitioned data stores while achieving the cost advantages of partial replication without the availability and latency problems of the simple extension.
