About Thailand IX

The Origin of National
Leading Digital Era

The Internet in Thailand as in the first generation was mainly to access overseas contents especially in the USA, European countries, Hong Kong and Singapore respectively. The network topology significantly contributed to an international Internet connection gateway capacity for accessing those international contents. The drawback is, the content exchange among Thai Internet users also needed to be routed internationally, outside the country, before returning them back because there was not any domestic Internet Exchange in Thailand at that time. This resulted, first, a high cost of Internet service fees. Second, content accessibility was inefficient as every content data had to be transited to the outbound countries which has a higher latency connection.

Consequently, in 1995, The Communication Authority of Thailand established National Internet Exchange (NIX) to be an Internet Exchange Point for exchanging domestic traffic which improved Thai internet traffic effectively with lower latency and lower cost.

In 2003, the Communication Authority of Thailand agency was corporatized into a Thai state-owned company as CAT Telecom Public Company Limited, with 100% of shares held by the Thai government. The NIX is also transferred to CAT Telecom PCL. Later NIX was renamed as Thailand Internet Exchange, Thailand IX, or TH-IX.

The majority of Peering Members are Thai Internet Service Providers where they were connected in OSI Layer-3 Internet Exchange

In the present, Thailand IX (TH-IX) is an OSI Layer-2 Internet Exchange network as the standard model. IXPs Nodes are located in:

Thailand IX (TH-IX) members can choose either CAT’s local access or leading local access network providers who operate in the Carrier data center and certified as a global standard service provider.

Thailand IX (TH-IX)’s peering members consist of ISP, Broadband provider, Mobile Operator, Government, Enterprise, Service Provider in Myanmar, Laos, Cambodia , as well as domestic and international Content Provider who tends to transfer the amount of content database into Thailand which will impact on Thailand IX (TH-IX) traffic service increase year by year. 

The number of peering members and the diversity of network operator which has been expected to increase in the future will be beneficial for Thailand IX (TH-IX) connection as it allows Internet network operators exchange traffic efficiently due to low latency time/ low hop count and less operation cost compares to International IP transit service connection or directly connects to each domestic content provider. Thailand IX (TH-IX) is the main Internet Exchange provider and aims to be the Internet Exchange Hub in Southeast Asia region further.
