Network PropertiesAn application might care about

• Bandwidth• Latency• Jitter• Reliability

– Packet loss– Standby / redundant diversity

• Isolation– Performance– Security

• In-net & edge processing / storage

• Location mobility

ComplexitiesBoth requirements and providers can be

• Time-varying• Differ by flow/stream within an application• Differ by user• Differ by circumstances (e.g. during a

disaster)• Might need to be coordinated /

orchestrated among applications• Determined by law or regulation

7

Balance PointsMight be

• Determined by regulators• Chosen by infrastructure providers• Be the result of priority assignment or

traffic engineering• Chosen by applications from a fixed menu• Negotiated by agents for the application

and infrastructure• Dynamically re-negotiated

US Ignite Apps WantAt Low Cost

• End-user Bandwidth (gigabit)

• Highly-responsive apps (gigabit, latency, edge infrastructure (locavore infrastructure))

• Real-time high-quality video (gigabit, latency, jitter, packet loss)

• Sensitive information apps (Isolation)

• Mission-critical apps (reliability plus the above)

Smart Things WantAt Low Cost

• End-user Bandwidth (gigabit)

• Highly-responsive apps (gigabit, latency, edge infrastructure (locavore infrastructure))

• Real-time high-quality video (gigabit, latency, jitter, packet loss)

• Sensitive information apps (Isolation)

• Mission-critical apps (reliability plus the above)

SDXes

• Integral to inter-domain application infrastructure

• Either– Do not impact a property when inserted– Are considered as part of the balance

Transparent

15

Don’t forget

• Connecting heterogeneous networks (services) (those with different properties) may benefit from more than packet passing (e.g. transcoding or an application gateway).

16

A Proposal for Proceeding

• Do (just) enough to support / demonstrate a very small number of inter-domain applications

• Above x3 or x5– See some different design points– So we can see similarities and differences

• Spiral with increased sophistication

Typical App Characteristics• Real-time (apparentlly instantaneous)• Very low latency• Reliable (no hiccups)• Cyberphysical interactions• Big data to the end user / anchor institution• Visual data exploration (“fly-through”)• Collaborative (in the moment)• Distributed
