Network traffic

Hi!

Let's say in my case, I have an organisation built in 3 countries. The main office is located in Singapore, other 2 in Malaysia and Indonesia respectively. These 3 offices are connected with 3 routers (that I have previously set up in the Cisco packet tracer).

I need help explaining this question:

How network traffic are routed between the 3 countries allow host from one country to communicate to the host at the other 2 countries?

Short answer: Through an ISP's WAN using something like MPLS and BGP.
Long answer : Sorry, not a network guy.

Traffic would leave the ISP via their border and route out to the remote site via BGP across other ISPs.

There can be L2 circuits across a large geological area of where a service is built between two ISPs, so the traffic is specified across two different ISPs. For example, ISP in country A has a NNI (network-to-network interface) with an ISP in country B. A L2 circuit is built from one ISP and a new order is raised to the other ISP, who then are contracted as a local hand-off to a customer. This is primarily regarding businesses.

Hope that's negligible, currently on shift and its 5am.

This sounds like a homework question to me.

I doubt they only use 3 routers to forward traffic.
