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.

    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.
