An introduction to Internet
numbers
What do I mean by Infrastructure
The Open Systems Interconnection (OSI) model
Layer 3
and
below
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)
IP addresses and ASNs

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.
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
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

• The first networks in Taiwan are predominantly service
providers and academics
• The newer networks are mostly from corporates
• Core networks are established
• Edge networks are growing

Taiwan IPv6
• Similar core network players as IPv4
• Populated by service providers and academic networks
– Just like IPv4 when it started back in 1990
• Hoping to see more networks turning on their IPv6
– Internet of Things network
• Manufacturers
• Utility companies
• Smart cities
Looking ahead
Looking ahead
• Global trends
– As more organizations interconnect with upstreams, downstreams
and peers, the number of advertised ASNs will continue to grow
– Opportunities to reduce cost, improve resiliency and performance will
be available to those with awareness of this rich network ecosystem
– New technologies such as SDN and network virtualization will drive
innovations and change the way networks are interconnected, so
expect to see a more dynamic ecosystem in the future
For discussion
• What’s the Internet experience like in Taiwan?
– From consumer’s point of view
– From corporation’s point of view
– From academic’s point of view
– From service provider’s point of view
• What can be done better?
• What will Taiwan’s Internet infrastructure looks like in the
future?
