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, IoTand 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.
