| Abstract | Hypertext Transfer Protocol-2 (HTTP/2) partially resolved the problem of Head-of-Line Blocking (HoLB) by multiplexing independent messages at the application layer. This enables simultaneous transmission of multiple requests over the same connection independently. However, this technique becomes ineffective when packet loss occurs in the Transmission Control Protocol (TCP) flow in which case all the independent streams are blocked until the retransmission of the lost packet; this problem is known as HoLB at TCP-level. The problem arises because the underlying TCP does not differentiate between independent messages/streams from application layer protocol. This study proposes a multistream framework for Fast TCP to support multiple independent messages/streams of the application. The proposed framework uses separate flows, buffers, and segments for each independent stream, and interleaves these segments over a single TCP connection. It makes TCP compatible with HTTP/2, reduces data delivery latency between transport and application layer, and alleviates head-of-line blocking. We implemented this framework in Fast TCP and carried out a simulation-based comparison between Multistream Fast TCP (MFast TCP) and Stream Control Transmission Protocol (SCTP). Our results show that MFast TCP significantly improved performance over SCTP in the event of HoLB. |

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.
