A quick overview


Sri Lanka’s Internet is no different to the Internet anywhere in the world.

Following is a brief discussion of the characteristics of Sri Lankan Internet infrastructure.

SL internet is 20 years old Started in 1995 with Dialup AccessAmong the lowest costs broadband markets in the worldCurrent penetration ~22% *Growth Rate 22% (CAGR 3yrs)*

Access


Major Telcos have Fiber Optic & Microwave infrastructure spread over the whole island.

Some Service Providers lease there capacity to others National Backbone Network (NBN) with OTN 100G DWDM

technology is operated by SLT for the use of all Service Providers.

Transport - National Connectivity


Submarine Cable Systems Connecting Sri Lanka

Currently, the primary and almost only International connectivity is via Optical Submarine cable systems.

Cable Redundancy:

East-West and India Connectivity via Submarine Cablesare used to improve Network Resiliency

Transport - International Connectivity


Internet Peering:1. Peering with Global Carrier ISPs & Content

a) All major ISPs connect with GLOBAL ISPs and also REGIONAL ISPs via submarine cable circuitsi. Peering via dedicated linksii. Peering at Global IXs

b) Peer with Content Networks & Content Distribution Networks (CDNs)i. Locally hosted at ISPsii. Hosted at Global IXs

2. IP Transit from Local Carrier ISPsPurchase IP Transit service from Local Large ISPs

Ex: Google, Akamai, Limelight…

Interconnect


Local Internet traffic exchange

Private Peering - Private peering links between ISPs Some ISPs have private links between them

IX Peering - Two exchange points- No settlement fees

Interconnect


NAT - Most Consumer IPv4 traffic is NATed at ISPsDNS - All Infrastructure ISPs provide DNS Resolvers &

DNS Caches for their customersDNS-Root Servers - Only i-Root server is available* in SL

Policy & Regulation


Policy & RegulationISPs:All access service providers have ISP LicensesIn addition, there are specialized ISPs serving specific business demands.

There are two types of ISP Licenses. Facility Based (FB) Non Facility Based (NFB)

The Operators shall not be entitled to establish its own transmission facility, but will be entitled to use a transmission facility of other licensed operators to connect subscribers and sites.


Internet Traffic:

The country total download traffic (peak) is roughly

50 – 60 Gbps *

Almost 95% Internet traffic is Non-Local

Some popular Content Caches are locally hosted @ ISPs

The two Internet Exchanges and Local Direct Peering serve

inter ISP traffic

* Estimated figure


Growth:We expect the Internet Penetration to grow rapidly with the penetration of Faster access via Fiber, LTE stimulates usageSMART Home/Office/Community initiatives are seen emerging in the marketInternet of Things (IOT) will drive always on connectivityConvenient & Cheaper Cloud services will need Ubiquitous Internet access

IPv6:Most of the ISPs have enabled IPv6 in their networks, with limited scope.Business Internet lines can get IPv6 from the major service providers*.Enabling IPv6 on Retail/Consumer services is on the boards for the very near future*. * with exceptions

FUTURE


Internet has become a critical contributor to Socio- Economic

development & influence.

Let us actively engage in the development & better use of the

Internet for improving the wellbeing and productivity of the people.
