Towards a carrier SDN: an example for elastic inter-datacenter connectivity.
نویسندگان
چکیده
We propose a network-driven transfer mode for cloud operations in a step towards a carrier SDN. Inter-datacenter connectivity is requested in terms of volume of data and completion time. The SDN controller translates and forwards requests to an ABNO controller in charge of a flexgrid network.

Deployment of OpenFlow/SDN Technologies to Carrier Services
The use of computing resources on network is becoming active in the Internet and private networks. OpenFlow/Software-Defined Networking (SDN) is drawing attention as a method to control network virtualization for the cloud computing services and other carrier services. This paper introduces examples of OpenFlow/SDN technologies applied to commercial cloud services. Various activities to expand ...
متن کاملOn the future integrated datacenter networks: Designs, operations, and solutions
Inter-datacenter networks (Inter-DCNs) and Intra-datacenter networks (Intra-DCNs) are entirely different in communication scales, architecture topologies and sizes, and characteristics of traffic flows. An Inter-DCN is built upon the existing Internet backbone with a fixed mesh topology and is hence difficult to accommodate any physical update or change without significant human intervention. S...
متن کاملCarrier-grade Network Management Extensions to the SDN Framework
The concept of software-defined networking (SDN) recently gained huge momentum in the industry, driven mainly by IT companies interested in datacenter applications. In this paper, however, we consider SDN applied in the carrier domain, which poses additional requirements on the network architecture, including network management functions. We derive concrete requirements for the use-case of a vi...
متن کاملInter-Datacenter Connectivity in Flexgrid-based Optical Networks
The huge energy consumption of datacenters (DC) requires an elastic resource management, e.g. by turning servers off when they are not used or turning them on to satisfy increments in the demand. Thanks to virtualization, jobs (e.g., web applications) can be encapsulated in virtual machines (VM) mixed with other workloads and consolidate them in the most proper server according to their perform...
