The document provides an overview of Internet infrastructure in Southeast Asia, focusing on Laos. It discusses key concepts like autonomous systems (ASNs) and routing. Visualizations show the interconnection of networks globally and in Southeast Asia. Laos currently has predominantly internet service providers and government networks, but more non-ISP networks are expected to deploy ASNs as the country develops similarly to its neighbors. Looking ahead, trends include more local interconnection to improve performance and reduce costs, as well as growth in local content and initiatives driving more networks across academia, businesses and other sectors.
4. What do I mean by Infrastructure
The Open Systems Interconnection (OSI) model
Layer 3
and
below
5. Sending data over the Internet
• Data is sent over the Internet in discrete packets
– Each packet can be a few bytes or a few hundred bytes, or even
larger
• Packets are sent from ‘source’ to ‘destination’
– When streaming YouTube movie on your mobile phone:
• YouTube server is mainly the source
• Your mobile phone is mainly the destination
• Every source and destination in the Internet must have an
IP address
– IPv4 example 203.0.113.15 (32 bit number)
– IPv6 example 2001:db8:200:ff:1:dc:77:ab (128 bit number)
7. Routing and ASN
• RFC 1930:
– An AS (Autonomous System) is a connected group of one or more IP
prefixes run by one or more network operators that has a SINGLE
and CLEARLY DEFINED routing policy.
– An AS has a globally unique number (sometimes referred to as an
ASN, or Autonomous System Number) associated with it. This
number is used in both the exchange of exterior routing information
(between neighbouring AS’s), and as an identifier of the AS itself.
8. Connecting to the Internet
202.178.112.0/24
2400:3E00:DD::/48 202.178.112.0/24
2400:3E00:DD::/48
Multi-homed network
MAY have a need for BGP and public ASN
Single-homed network
No need for public ASN
9. Why multihome with BGP and use a
public ASN?
Good interconnection strategy can lower cost of
operation by directing traffic through the most cost
effective connections wherever possible
Understanding where your network traffic goes and
when possible shortening the path to your main
customers/suppliers/partners could result in better
overall network experience
Looking further than next hop path diversification allows
you to better evaluate interconnection options, which in
turn could result in better network resiliency

15. The Internet
15
• Networks worldwide
interconnect to form the
Internet. They include ISPs,
Internet Exchange Points,
Universities, Corporate
networks, etc.
• Each dot represents an AS
• There are 50,000+ ASNs
currently active in the
Internet

18. Data source
• Routeviews.org
– RIBs from the Oregon Internet Exchange, for both IPv4 and IPv6
• 12 November 2015 data (taken at 2am UTC)
• This is a snapshot, not live data
• The list of ASNs per country/economy is sourced from
the NRO's global delegated statistics file

39. Observation
• The networks in Lao are predominantly service providers
• The latest delegation (in 2015) is to a systems integrator
• If Lao Internet is going to grow similar to the other
economies in the South-East Asia region, expect to see
more academic and corporate to deploy ASNs:
– Universities
– Hosting/data centers
– System integrators
– Banks
– etc.
41. Looking ahead
• Global trends
– As more organisations interconnect with upstreams, downstreams and
peers, the number of advertised ASNs will continue to grow
– New technologies such as SDN and network virtualisation will drive
innovations and change the way networks are interconnected, so expect
to see a more dynamic ecosystem in the future

42. Looking ahead
• Regional trends
– Keeping traffic local by establishing multiple or bilateral peering
arrangement
– Reduce cost
– Improve performance
– Improve user experience
– Growth of local content
– e-Gov initiatives
– Domestic e-Commerce
– Domestic/regional News
– Local social media/forums/mailing lists
– Entertainment (games, movies etc.)
– Caching of international content

43. For discussion
• What’s the Internet experience like in Lao?
– From consumer’s point of view
– From academic’s point of view
– From corporation’s point of view
– From service provider’s point of view
• What will Lao’s Internet infrastructure look like in the future?
