Abstraction Layer Based Service Clusters Providing Low Network Update Costs for Virtualized Data Centers

Ali Kashif Bashir, Yuichi Ohsita, Masayuki Murata
International Journal on Advances in Software   unpublished
This abstraction layer offers several advantages, however, in this work, we considered network update cost when recovering from failures as a parameter of evaluation.  ...  Keyword-network virtualization; service clusters; network failures; virtual data center network architecture; infrastructure for cloud applications; abstraction of virtual resources.  ...  This virtualization introduces an abstraction that allows network operators to manage and modify networks in a highly flexible and dynamic way.  ...

SDN's logically centralized control provides an insertion point for programming the network.  ...  While this is an ambitious long-term goal, our prototype built on the PostgreSQL database exhibits promising performance even for large scale networks.  ...  View maintenance [9] and update [2, 4, 7, 5, 13] mechanisms are the "runtime" for view abstractions, constructed through normal SQL operations (queries and updates).  ...

Consistent updates for software-defined networks

Mark Reitblatt, Nate Foster, Jennifer Rexford, David Walker
2011 Proceedings of the 10th ACM Workshop on Hot Topics in Networks - HotNets '11  
Because SDN is a clean-slate platform, we can build general, reusable abstractions for network updates that come with strong semantic guarantees.  ...  We propose two simple, canonical, and effective update abstractions, and present implementation mechanisms.  ...  We wish to thank Hussam Abu-Libdeh, Robert Escriva, Mike Freedman, Mike Hicks, Eric Keller, Srinivas Narayana, Alan Shieh, and the anonymous reviewers for many helpful suggestions.  ...

Inter-Domain Routing Scalability in Optical DWDM Networks

Q. Liu, C. Xie, T. Frangieh, N. Ghani, A. Gumaste, N. Rao, T. Lehman
2008 2008 Proceedings of 17th International Conference on Computer Communications and Networks  
To address these scalability limitations, novel routing update triggering policies for multi-domain DWDM networks are developed.  ...  Recent studies on inter-domain DWDM networks have focused on topology abstraction for state summarization, i.e., transforming a physical topology to a virtual mesh, tree, or star network.  ...  To resolve this challenge, some studies have proposed alternate topology abstraction schemes with fewer virtual links, e.g., [7] - [10] for data networks, [17] for optical networks.  ...

Abstractions for model checking SDN controllers

2013 2013 Formal Methods in Computer-Aided Design  
In this case study, we extend the state of the art by presenting abstractions for model checking controllers for an arbitrarily large number of packets exchanged in the network.  ...  While there is recent research in formal verification of these networks, model checking the controller behavior as it updates the underlying network has only seen limited application.  ...  Acknowledgment: We thank Jennifer Rexford and Muralidhar Talupur for their helpful ideas and feedback.  ...

To address these concerns a detailed GMPLS-based hierarchical routing framework is proposed for multi-domain DWDM networks with wavelength conversion.  ...  This solution uses mesh topology abstraction schemes to hide domaininternal state.  ...  For example [11] adapts star abstraction to alloptical DWDM networks by generating a virtual node for each domain.  ...

Taming Mobility Management Functions in 5G: Handover Functionality as a Service (FaaS)

Albert Codes Morales, Adnan Aijaz, Toktam Mahmoodi
2015 2015 IEEE Globecom Workshops (GC Wkshps)  
Clearly, there is a trade-off between keeping the abstract model up-to-date and the increased overhead of the updates.  ...  The investigations are carried out in network simulator (ns-3) and it can be seen while reducing frequency of updates results in the increased packet loss, an optimal balance between overhead and packet  ...  As mentioned earlier, for the Handover FaaS platform considered in this paper, the SDN-controller stores the abstract view of the network, and is aware of the current network topology and its future states  ...
