Local Network Latency (LNL): Round Trip Time (RTT) taken to access a national or site hosted within the country
Requirement: LNL < 85ms for 95% of the peak time
International Network Latency (INL) : Round Trip Time (RTT) to the first US entry point.
Requirement: INL < 300ms for 95% of the peak time

Few points to ponder
o Do we always get what is promised, especially when downloading from International sites?
o Are these trends transitional or long-term?
o Are Home packages better value for money than Business packages?
o Should we demand better QoS for Games/video?
o Can we be complacent because the situation is not too different in India?
o Should we adopt Singapore standards or more stringent ones?

Local Loop Unbundling (LLU)
• Legislated in only few South-East Asian countries including South Korea, Hong Kong, Taiwan and Malaysia– Mandatory LLU legislation in Hong Kong to be fully
withdrawn by June 2008, on the basis that policy may discourage investment in existing network infrastructure & additional investment in fibre-based, alternative customer access networks by competitors
• However, LLU is rarely used in South Asian countries or anywhere in developing world

LLU: The Case of India
• April 2004: TRAI recommends Shared Unbundling and Bit Stream Access– BSNL and MTNL (incumbents) do not support LLU, citing
complications in other countries without seeming benefits to consumers
• Jan 2008: TRAI retracts LLU ruling because of– Complexity – Possible friction among operators leading to degradation of QoS– Insufficient line capacity in the country need to provide
incentives for new roll-out

Broadband QoS regulating in Singapore
Network Availability (NA) = (Mins operational – Mins non-operational ) x 100%
Mins operational
Requirement: NA > 99% (Excluding pre-announced maintenance periods)
Bandwidth Utilisation (BU)=Peak utilisation level in each segment x 100
Total bandwidth available for that segment
Requirement: BU < 90% (average of all segments taken)If it exceeds 90% for 3 consecutive months, the provider is
directed to purchase more bandwidth. *Cannot be tested by the consumers

Broadband QoS regulation in other countries
• Malaysia –Regulates QoS but not much information available
• Australia – No regulation but a manual available for consumers
• South Korea – Uses two approaches. Monitor QoS using an automated methodology and conduct user satisfaction surveys
• Bahrain – A consultation has been done, but no regulation
• UK – Conducts user satisfaction surveys. Customers were queried on quality and it was concluded that 90% were satisfied with quality (speeds) of broadband. Satisfaction with narrowband at 60%.
