Services – challenges

• Change in community.
• Increasing demand for services that we
  have not previously provided (e.g.):
  • web mail, filtering and hosting; and
  • off-site resolver.
• Increasing emphasis on security services:
  • security health check;
  • central e-mail testing; and
  • site incident investigation service.
Challenges…

• Connection of Adult Community Learning
  community.
• Connection of schools.
Education networks

– attached to SuperJANET in Cardiff
– 22 unitary authority networks
Challenges…

• Connection of Adult Community Learning
  community.
• Connection of schools.
• Upgrade of FE community.
• Reliability
  • Change in use of internet by HE and FE
  • Critical to the business

Reliability    • minimise single points of failure
               • reduce components and complexity
Scalability    • UKERNA control of costs of adding large
                 amounts of bandwidth when needed
Separability   • configure parallel purpose-built networks via
                 control at transmission-level

Flexibility    • UKERNA ability quickly to change
                 configuration of network when needed
Key objective …
