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
