Building an access network for demand and scale – new challenges – Kurt Rogers, Chorus
- Over 1 million broadband connections on access network
- 70-80% of BB connections
- Average connection sped now near 20Mb/s due to VDSL and Fibre
- Busiest 15 minute period (around 9pm Thursday) of week averaging 0.5Mb/s per user ( up from 100kb/s just 3 years ago )
- Jump in mid-2013 when Netflix and Lightbox launched
- Average bandwidth per user growing 50%/year. Grown that much in 1st half of 2015
- Quite a few people still on ADSL1 modems when ADSL2 would work
- Same a lot of people can get VDSL that don’t realize
- Lots of people on 30Meg fibre plan at the start, now most going for 100Mb/s
- Rural broadband (RBI)
- 85k lines upgraded to FTTN
- Average speed jumped 5.6Mb/s to 15Mb/s after a single rural cabinet upgraded cause everybody could now use ADSL2 and faster uplink. One fibre guy got 48Mb/s on VDSL, other 37Mb/s
- More speed out there than some people realize
- VDSL bandplan moving from 997 to 998. Trail average speed increases were from 32 to 46Mb/s for downstream. Minimal change on upstream speed.
- Capacity
- Aggregation link bandwidth. Alert threshold at 70%, Max threshold at 90%
- Technology down the road to speed up aggregation links with Next Generation PON technology
The new smart ISP – Colin Brown, GM of Networks at Spark
- Working on caching infrastructure, bigger and closer to their edge
- Big traffic growth this year
- Big growth in mobile traffic especially upload
- 60% of phones in stores are 4G capable
- Providers investing a lot of money , profits lower. Less like banks, more like airlines
- Technology refresh every 5 years rather than every 10
