A Practical Architecture for an Anycast CDN

Hussein A. Alzoubi, Seungjoon Lee, Michael Rabinovich, Oliver Spatscheck, Jacobus Van Der Merwe
2011 ACM Transactions on the Web  
In this article we re-evaluate IP Anycast for CDNs by proposing a load-aware IP Anycast CDN architecture.  ...  However, while briefly considered as an enabler for content delivery networks (CDNs) when they first emerged, IP Anycast was deemed infeasible in that environment.  ...  Our revisiting of IP anycast as a redirection mechanism for CDNs was prompted by two recent developments.  ...

Anycast-aware transport for content delivery networks

Zakaria Al-Qudah, Seungjoon Lee, Michael Rabinovich, Oliver Spatscheck, Jacobus Van der Merwe
2009 Proceedings of the 18th international conference on World wide web - WWW '09  
Anycast-based content delivery networks (CDNs) have many properties that make them ideal for the large scale distribution of content on the Internet.  ...  However, because routing changes can result in a change of the endpoint that terminates the TCP session, TCP session disruption remains a concern for anycast CDNs, especially for large file downloads.  ...  Finally, anycast CDNs in general keep control over request routing with the CDN.  ...

Anycast Latency: How Many Sites Are Enough? [chapter]

Ricardo de Oliveira Schmidt, John Heidemann, Jan Harm Kuipers
2017 Lecture Notes in Computer Science  
Anycast is widely used today to provide important services including naming and content, with DNS and Content Delivery Networks (CDNs).  ...  An anycast service uses multiple sites to provide high availability, capacity and redundancy, with BGP routing associating users to nearby anycast sites.  ...  IP anycast is also used by several web CDNs (Bing, CloudFlare, Edgecast).  ...

Revisiting caching in content delivery networks

Muhammad Zubair Shafiq, Alex X. Liu, Amir R. Khakpour
2014 The 2014 ACM international conference on Measurement and modeling of computer systems - SIGMETRICS '14  
Content Delivery Networks (CDNs) differ from other caching systems in terms of both workload characteristics and performance metrics.  ...  For workload characteristics, CDNs deal with extremely large content volume, high content diversity, and strong temporal dynamics.  ...  redirection, URL rewriting, or anycast [7] .  ...

Revisiting Comparative Performance of DNS Resolvers in the IPv6 and ECS Era [article]

Rami Al-Dalky, Michael Rabinovich
2020 arXiv   pre-print
This paper revisits the issue of the performance of DNS resolution services available to Internet users.  ...  Finally, in most locations, we observe IPv6 penalty in the latency of client-to-CDN-edge-server mappings produced by the resolvers.  ...  Akamai uses widely distributed anycasted ADNS [2] and its own private backbone for communication among its points of presence [19] .  ...

Characterizing a Meta-CDN [chapter]

Oliver Hohlfeld, Jan Rüth, Konrad Wolsing, Torsten Zimmermann
2018 Lecture Notes in Computer Science  
Services that tackle this task emerged, also known as CDN broker, Multi-CDN selectors, or Meta-CDNs. Despite their existence, little is known about Meta-CDN operation in the wild.  ...  CDNs have reshaped the Internet architecture at large.  ...  ., topology, load, or delay, to the CDN, which in turn bases its server selection on the returned information. The idea and concept of the presented approach is revisited by Frank et al.  ...

Distributed Information Object Resolution

Kostas Pentikousis
2009 2009 Eighth International Conference on Networks  
We revisit the implications of DNS involvement in URI resolution and discuss how two different types of content distribution networks work with respect to name resolution.  ...  Anycasting has also proven an effective method to alleviate performance concerns.  ...  Overprovisioning is key and anycasting has been widely adopted. According to [16] , more than 95% of root name servers use anycast and so do all large generic top-level domains (gTLD) name servers.  ...
