Abstract: |
To investigate the scalability of
multimedia storage servers from tens to hundreds of users. Progress:
This project is also being supported by Olivetti Research Limited,
Cambridge. The project has now developed into two separate but
complementary strands. One is the investigation how distributed
multimedia fileservers can cooperate over a local and wide area to
produce a truly distributed multimedia server, and involves the
automatic transfer of multimedia data to its optimum position in the
storage hierarchy. The other is concerned with the nodes of the
distributed multimedia fileserver where special hardware and
knowledge of the composition of the data on the storage server can
be used to produce a truly scalable system. One of the requirements
of a scalable system is its ability to adjust dynamically to
overload conditions by the addition of extra resources. Research in
this project shows that the use of conventional techniques such as
file replication and network striping do not solve the scalability
problem. Initial investigations show that a hybrid combination of
network striping and file replication exploiting multi-resolution
compression techniques is a promising approach to a scalable storage
architecture. Various multi-resolution schemes and how they could be
used to allow the scalability of the multimedia server node are
currently being investigated with the support of the Olivetti
Research Limited and their specially developed hardware.
