Faster Content Access in KAD

Moritz Steiner, Damiano Carra, Ernst W. Biersack
2008 2008 Eighth International Conference on Peer-to-Peer Computing  
In this paper, we analyze in detail the content retrieval process in KAD, the implementation of the DHT Kademlia that is part of several popular peer-to-peer clients.  ...  In particular, we present a simple model to evaluate the impact of different design parameters on the overall lookup latency.  ...  Evaluation In this section we measure the performance of the content management in KAD.  ...

Evaluating and improving the content access in KAD

Moritz Steiner, Damiano Carra, Ernst W. Biersack
2009 Peer-to-Peer Networking and Applications  
We analyze in detail the content retrieval process in KAD. KAD implements content search (publish and retrieval) functions that use the Kademlia Distributed Hash Table for content routing.  ...  We identify the key design parameters in KAD and present an analytical model to evaluate the impact of changes in the values of these parameters on the overall lookup latency and message overhead.  ...  Evaluation In this section we measure the performance of the content management in KAD.  ...

Adaptive Edge Content Delivery Networks for Web-Scale File Systems [article]

João Tiago and David Dias and Luís Veiga
2022 arXiv   pre-print
The InterPlanetary File System (IPFS) is an hyper-media distribution protocol, addressed by content and identities. It aims to make the web faster, safer, and more open.  ...  We add a novel crucial key component to enable an IPFS-based decentralized Content Distribution Network (CDN).  ...  If not found, it will resort to the content routing module, in our case, the Kad-DHT module.  ...

P2P Second Life: Experimental Validation Using Kad

M. Varvello, C. Diot, E. W. Biersack
2009 IEEE INFOCOM 2009 - The 28th Conference on Computer Communications  
Our communication infrastructure is implemented on the top of Kad, the P2P network that supports millions of eMule users.  ...  ACKNOWLEDGEMENTS The authors would like to thank Moritz Steiner for the precious help to integrate our P2P infrastructure on top of Kad.  ...  A source key identifies the content of a file, and a keyword key classifies the content of a file. We use the Kad API [3] to integrate our P2P infrastructure on top of Kad.  ...
