Issue Date:August 2009
pp. 101-104
Network management operations are complicated, tedious and error-prone, requiring significant human involvement and expert knowledge. In this paper, we first examine the fundamental components of management operations and argue that the lack of automation ...
     
Anycast-aware transport for content delivery networks
Found in: Proceedings of the 18th international conference on World wide web (WWW '09)
By Jacobus Van der Merwe, Michael Rabinovich, Oliver Spatscheck, Seungjoon Lee, Zakaria Al-Qudah
Issue Date:April 2009
pp. 66-66
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, T...
     
Anycast CDNS revisited
Found in: Proceeding of the 17th international conference on World Wide Web (WWW '08)
By Hussein A. Alzoubi, Jacobus Van der Merwe, Michael Rabinovich, Oliver Spatscheck, Seungjoon Lee
Issue Date:April 2008
pp. 1-7
Because it is an integral part of the Internet routing apparatus, and because it allows multiple instances of the same service to be "naturally" discovered, IP Anycast has many attractive features for any service that involve the replication of multiple in...
     
Live data center migration across WANs: a robust cooperative context aware approach
Found in: Proceedings of the 2007 SIGCOMM workshop on Internet network management (INM '07)
By Jacobus Van der Merwe
Issue Date:August 2007
pp. 262-267
A significant concern for Internet-based service providers is the continued operation and availability of services in the face of outages, whether planned or unplanned. In this paper we advocate a cooperative, context-aware approach to data center migratio...
     
The case for semantic aware remote replication
Found in: Proceedings of the second ACM workshop on Storage security and survivability (StorageSS '06)
By Gal Niv, Jacobus Van der Merwe, K.K. Ramakrishnan, Prashant Shenoy, Xiaotao Liu
Issue Date:October 2006
pp. 79-84
This paper argues that the network latency due to synchronous replication is no longer tolerable in scenarios where businesses are required by regulation to separate their secondary sites from the primary by hundreds of miles. We propose a semantic-aware r...
     
BGP convergence in virtual private networks
Found in: Proceedings of the 6th ACM SIGCOMM on Internet measurement (IMC '06)
