INASP Optimising and managing bandwidth in low bandwidth environments
The bandwidth challenge
Bandwidth management and
optimization • Available bandwidth is limited and insufficient
to meet demand
in research and education institutions • Existing capacity is usually running at
maximum capacity
in low bandwidth environments – As a result it is often unusable
– Universal flat lining during working hours
• The cost of bandwidth is extremely high
Martin Belcher • Expanding bandwidth capacity is limited due

to finances, supply, technology

What does this mean? Detail of the challenge
• The university is not participating in the digital information
revolution
• Bandwidth is a resource that is…
– The university is not providing its staff, researchers and students with the – Limited, in high demand, expensive, of high value
information they require
– Existing digital library resources are under-utilised, further investment in • Existing bandwidth is often not managed
digital library technology is unrewarding (high cost/low use)
– Lack of access to up-to-date, local, regional and global research information • 59% of institutions do not monitor or manage
= restricted research potential
bandwidth at all
• Low level of return on investment
– High network costs (c.$5000+ per month) • Further examination of the data indicates that
– Low level of use (page downloads taking >10 minutes)
this figure is in fact much higher
• Low incentive to invest more within the university infrastructure
• See the ATICS Report: www.atics.info for full details of
– Poor ICT investment (including staff, training, etc.)
the situation in African universities
– More computers / same bandwidth = slower access / less research

Possible solutions?
• Do nothing ! ATICS: “Improving bandwidth
– often the reality but not the answer management is probably the easiest way
• More bandwidth and lower cost for universities to improve the quantity
– Local, national and international consortia
and quality of their bandwidth for
• Better management of the existing resource
– Improved access, no additional bandwidth costs educational purposes.”
• Combined approach (low cost + management)
– Half price + double usable speed = quadruple
access
– Increased long-term sustainability

Executive management roles in
Bandwidth management
bandwidth management
1. Monitoring and management of available resource • Leadership
2. Optimisation of the resource to ensure value for – Authority behind a decision or action is essential
money and fitness of purpose
• Supportive policy environment
– Any developments must be sponsored and
• Three key groups to ensure success: advocated
– Executive management
– Senior implementation management • Strategic direction
– Technical staff involved in the day-to-day implementation – Bandwidth management needs to be integrated
within the university policy

Leadership and strategic direction Supportive policy environment
• How does bandwidth connectivity help to • Policy is an enabling element of higher
achieve strategic aims and objectives? education management
• What implications are there for policy, – Some things are denied in order to make other
things possible
resources and priorities within the institution?
– Without policy it is impossible to manage key
• How can the strategy be realised by actions aspects of bandwidth use
and results? – Policies will need to restrict how bandwidth is used
• How can consensus be achieved and (and is unlikely to be popular if managed badly)
mobilised? • Policy development must be consultative,
– Changing working patterns may be unpopular supported and led from the top

Leadership and accountability Resourcing
• Successful implementation of bandwidth • Bandwidth management is a strategic priority
strategy can only be achieved by ensuring – no institution of higher education can deliver on its
accountability: mission without good connectivity
– Within the IT department • Resources need to be identified to ensure
– Within the user community successful implementation of bandwidth
– Within the executive management management
• Consider no expansion of connectivity until
current resource is well managed

Recommendations for senior
The IT department as a resource
management
• The IT department must be adequately • Make bandwidth management a priority
equipped and managed • Be safe (ensure safe Internet access)
– appropriate IT governance • Respond to demands
– appropriate alignment of IT operations with
institutional objectives • Encourage positive behaviour
– appropriate resourcing of IT staff and operations • Monitor the IT team
– appropriate benchmarking and explanation of • Give everyone an identity (user monitoring)
bandwidth use
• Evaluate connection options regularly
• Join forces (collaboration with other institutions)

What is available?
• Information briefing packs targeted at senior institutional
Management seminars, training support managers and ICT professionals.
• Policy development workshops and training materials to support
and information resources to support the development of supportive policy environments.
• Network traffic monitoring and analysis workshops, training
bandwidth management capacity materials and software tools.
development • Community portal for resource distribution and online
information exchange.
• Network control and network traffic shaping workshops, training
materials and software tools.
• Content caching and filtering and authentication workshops,
training materials and software tools.
• Standalone training and documentation resources in bandwidth-
friendly Email service provision and scheduled download
strategies and techniques.

When and where? Institutions and NRENs getting involved
• Seminars and training will be run at national and local • NRENs (where they exist) could host a regional,
level in: national or local seminar or workshop events
– Ethiopia, Ghana, Kenya, Malawi, South Africa, Tanzania, • Institutional representatives participating in the
Uganda, Zambia, Zimbabwe
seminars or training workshops
• Regional events for francophone Africa:
– Rwanda, Senegal, Cote d'Ivoire, Congo and at least one
• Providing additional support to extend the
other country programme beyond the current funding
• Timetable boundaries
– Pilot workshops October 2005, further workshops after this • NRENs would seem ideal holders and facilitators
every 1-3 months of this information
• Technical partners involved in software tool
development
