| Abstract | Hybrid networks contain both legacy and programmable network switches and allow operators to reap the benefits of Software-defined networking (SDN) without upgrading the entire network. Previous research shows that adding SDN capabilities to switches at strategic places in a network and ensuring that each flow traverses at least one such switch is sufficient to achieve many SDN control paradigms, such as routing or access control. However, the control points are still limited to the SDN-enabled devices and operators cannot enforce fine-grained policies on the legacy paths between SDN switches. We present Telekinesis, a network controller that enables finer-grained routing control over legacy paths in hybrid networks using OpenFlow. To update routing entries in legacy switches, we introduce a new flow control primitive, LegacyFlowMod. LegacyFlowMod uses OpenFlow's PacketOut function to send a special packet on a specific interface of a legacy switch and remotely manipulate the forwarding entry associated with the source of the packet. Using simulations on random network topologies with varying degrees of OpenFlow deployment, we show that Telekinesis can provide more diverse path control than an OpenFlow-only controller: even when only 20% of switches are OpenFlow-enabled, we can update 70% of the paths. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
