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.

From requirements to solution
• UKERNA ability quickly to change configuration of network when needed
• configure parallel purpose-built networks via control at transmission-level
• UKERNA control of costs of adding large amounts of bandwidth when needed
• minimise single points of failure• reduce components and complexity

Backbone Service Components
• building block: raw bandwidth channels• 2.5Gbps / 10Gbps or subdivisions (e.g. 1G
Ethernet / 155Mbps) – 40Gbps in the future
• IP production service built over channels• other services also built over separate
channels• e.g. high-capacity bandwidth channels:
– Regional Network/Regional Network or – RNO/international (UKLight integration)
