Standardization Activities

  V. Roca, ``FCAST: Scalable Object Delivery for the ALC and NORM Protocols’’, IETF RMT Working Group, draft-roca-rmt-newfcast-00.txt (Work in Progress), September 2008. (ASCII)

In brief: This is an attempt to standardize the FCAST tool for both ALC and NORM, without infringing Nokia’s patent.

  T. Paila, M. Luby, R. Lehtonen, V. Roca, R. Walsh, ``FLUTE - File Delivery over Unidirectional Transport (revised)’’, IETF RMT Working Group, draft-ietf-rmt-flute-revised-03.txt (Work in Progress), January 2007. (ASCII)

In brief: This is a revision of the FLUTE specifications.

  T. Paila, M. Luby, R. Lehtonen, V. Roca, R. Walsh, ``FLUTE - File Delivery over Unidirectional Transport’’, IETF RMT Working Group, Request For Comments RFC 3926, October 2004. (ASCII)

In brief: This is the official specification of the FLUTE application and its relationships with ALC.

  C. Neumann, V. Roca, R. Walsh, ``File Aggregation Scheme for FLUTE’’, IETF RMT Working Group, draft-neumann-rmt-flute-file-aggregation-02.txt (Work in Progress), October 2005. (ASCII)

In brief: this document explains how to optimize FLUTE/ALC transfers when dealing with a large collection of small objects. The performance gains can be very, very, significant then...

Publications

  V. Roca, B. Mordelet, ``Improving the Efficiency of a Multicast File Transfer Tool Based on ALC’’, INRIA Research Report Number 4411, March 2002. (PDF)
Also in 7th IEEE Symposium on Computers and Communications (ISCC’02), Toarmina, Italy, July 2002

In brief: this document explains how to manage the transmission of several objects, or large objects, in order to reduce the memory requirements at a receiver and/or optimize the reception speed. This is the key techniques used by our FLUTE/ALC and FCAST/ALC tools.

In brief: This is the initial I-D that sketched the FCAST/ALC application, back in 2000. See Annex A.3: File Transfer using ALC - "Fcast".
