Akamai Introduction


Akamai Overview Who is Akamai? Akamai is a leading provider of a Cloud platform, which delivers, accelerates and secure content and APPLICATIONS over the Internet. Our key differentiator is our highly distributed (intelligent) platform, made up of more than 240,000 servers in 130 countries.

The Akamai Intelligent Platform The world’s largest on-demand, distributed computing platform delivers all forms of web content and applications

Typical daily traffic: • More than 3 trillion requests served • Delivering over 60 Terabits/second

The Akamai Intelligent Platform:

240,000+ Servers

3,900+ Locations

130+ Countries

1,700+ Networks

1300+ Cities


Traffic Snapshot

Traffic view shows Internet traffic levels by Akamai server locations in data centers all over the world. Data includes current hits per second and total page views per minute.


Basic CDN Technology

Akamai mapping


How CDNs Work When content is requested from CDNs, the user is directed to the optimal server to serve this user There’s 2 common ways to do that: • Anycast: the content is served from the location the request is received (easy to

build, requires symmetric routing to work well)

• DNS: the CDN decides where to best serve the content from based on the resolver it receives the request from, and replies with the optimal server


How Akamai CDN Work Example of Akamai mapping

• Notice the different AAAA records for different locations: [Taipei]% dig www.akamai.com

www.akamai.com. CNAME e1699.dscx.akamaiedge.net.

e1699.dscx.akamaiedge.net. 20 IN AAAA 2600:1417:1b:188::6a3

[Taichung]% dig www.akamai.com

www.akamai.com. CNAME e1699.dscx.akamaiedge.net. e1699.dscx.akamaiedge.net. 20 IN AAAA 2600:1417:18:18e::6a3

How Akamai CDN Work Akamai uses multiple criteria to choose the optimal server

These include standard network metrics: • Latency • Throughput • Packet loss

These also include things like CPU load on the server, HD space, network utilization, etc.


Akamai Mapping (Simplified)

1) end-user requests www.example.com from ISP NS

2) ISP NS recursively (multiple iterations) looks up www.example.com being referred to authoritative Akamai NS (by CNAME) 3) ISP NS asks authoritative Akamai NS 4) Akamai NS looks up IP of requestor (ISP NS) and replies with optimal server IP to serve content (local cluster in that ISP) 5) ISP NS replies to end-user who 6) requests content from local Cluster

end-user ISP NS 1.2.3.4

root/TLD/intermediate NS (recursive lookup until reaching authoritative NS)

Peering with Akamai

Akamai connection in Taiwan


Why Akamai Peers with ISPs Improved performance

• Akamai tries to serve content as “close” to the end users

Peering gives better throughput • Reduced latency and packet loss

Redundancy • Having more possible vectors to deliver content

Burstability • During large events, having multiple networks allows for higher burstability


Why Akamai Peers with ISPs Peering reduces costs

Reduces transit bill

Network Intelligence Receiving BGP directly from multiple ASNs helps CDNs map the Internet

Backup for on-net servers

If there are servers on-net, the peering can act as a backup during downtime and overflow Allows serving different content types


Why ISP peer with Akamai Performance

• Akamai and ISPs are in the same business, just on different sides - we both want to serve end users as quickly and reliably as possible

• You know more about your network than Akamai ever will, so working with Akamai directly can help them deliver the content more quickly and reliably

Cost Reduction • Transit savings • Possible backbone savings


Akamai peering connection in Taiwan Akamai is connected to TPIX to send traffic to peered members Node: Chief Telecom LY2 Port: 10G IPv4 = 203.163.222.48/24 IPv6 = 2406:d400:1:133:203:163:222:48/112

This does not mean you will see all Akamai traffic

• The Akamai node connecting to TPIX is aim to serve mainly mid-tier traffic to TPIX members.


How Akamai serve traffic to TPIX peered members

Transit

Peer Network

• Akamai TPIX node do not have a backbone, so the IX instance is independent

• Akamai uses transit to pull content into the servers

• Content is then served to peers over the IX

Origin Server
