Our offer to you today
• Help you to understand the mismatch between:
– What people are aspiring to achieve (demand)
– What the broadband industry is doing (supply)
• Propose how to close the gap
– Technically grounded in reality
– Practical advice on how to proceed

Our four key messages
1. Speed (‘bandwidth’) is no longer a helpful model for broadband.
2. Suppliers are being forced into a death spiral.
3. Regulators and government are unintentionally driving unhelpful behaviour by focusing only on speed.
4. Users and suppliers need to re-frame the resource model to be sustainable.

RECOMMENDATIONS
What operators should be asking themselves
1. Why am I trying to solve my scheduling problems with more capacity?
2. For my key customer applications, am I delivering the network supply that enables good QoE?
– i.e. am I delivering the right loss and delay?
3. Given that there is a trading space, am I constructing and offering the right data transport products?

What regulators should be asking themselves
1. What is the value that society is getting from demanding more speed?
2. Measurement is de facto regulation, therefore are we measuring the right thing?
3. What are the key applications that need managed QoE and cost to drive societal benefits?
4. Are the trades being performed in a manner that is transparent and non-discriminatory?

What users should be asking themselves
1. What are the unserved needs of enterprises and their dispersed workforces?
2. How to get the right broadband performance for the least cost?
3. What are the risks in buying and delivering new fit-for-business services?
4. What are the best ways to mitigate and manage those risks?

DESCRIBED IN DETAIL ON FOLLOWING SLIDES
What are the unserved needs of enterprises and their dispersed workforces?
Retrospective: Measure QoE slack/hazards • Based on what you’ve already got, know what
broadband-related business QoE hazards exist. • Exploit full upside of QoE slack safely in future.
Prospective: Model QoE requirements
• Make business promises on QoE that can be delivered, or represent a managed and quantified risk.
• Cost-in the capacity and QoE requirements to continue to keep your promises of business performance.

How to get the right broadband performance for the least cost?
• Time-shift your own demand – At all timescales
• Engage in graceful degradation – Proactively manage the consequences of supply
failure
• Manage supply and demand at key system elements (under your control) – Keep those elements within their predictable region
of operation – Avoid becoming part of the problem

What are the risks in buying and delivering new fit-for-business services?
• More speed ≠ more value
• Beware the ‘frequentist performance fallacy’ – Things can get worse, and do
– The past is not a good guide to the future
• Beware correlated failures & correlated loads – Understand how failures are linked
– Understand your business processes which cause load to be correlated
– Consider these issues in your business continuity plans

What are the best ways to mitigate and manage those risks?
Buy and provision:
• Characterise and document your own appetite and capacity for risk
• Understand properties of bearers from different suppliers (DSL, FTTC, cable, FTTP, MPLS, carrier ethernet, etc.) and their failure modes and likely time to repair
Operational:
• Don’t over-drive (unless you know the consequences)
• Manage your own contention and its QoE effects

SUMMARY & CONCLUSIONS
Anticipating the new landscape
• Suppliers: – Hiding behind existing Ts&Cs based on bandwidth will not meet the
market and regulatory needs – The money will move to suppliers who deliver a value proposition
expressed in customer terms, not network-centric terms
• Regulators: – Measure the right thing! (Performance and resilience, not ‘speed’) – Ensure that the industry is delivering value
• Customers: – Understand not all broadband is the same – Become more discriminating and sophisticated buyers – Articulate the value of hazard mitigation to suppliers and regulators
