Bristol: Liveable, Sustainable & Resilient City

Bristol Is Open: A Joint Venture
Open Programmable City

Bristol Is Open (BIO)
• We are building a research network integrating optical, wireless, IoT
and computing to provide an open and experimental platform in
the centre of Bristol
• We offer the test-bed as utility for experimentation: City
Experimentation as a Service
• It will support City-driven digital innovation
• Three main technology pilars:
• Technology agnostic
• SDN
• Hardware programmability

Network Slicer : FlowVisor
A new FlowVisor can define network
‘slices’ by any combination of:
• Switch ports
• Wavelengths
• Spectrum (layer 0/1)
• Ethernet address or type (layer 2)
• IP address or type (layer 3)
• TCP/UDP port or ICMP code (layer 4)

Physical Layer impairments are taken
into account before network ‘slicing’.
The network ‘slices’ have guaranteed
Quality of Transmission (QoT)
Many Virtual Networks (‘slices’) can
coexist. They are isolated and can be
controlled and operated individually.
