By having an IXP, the use of international bandwidth can be reduced resulting in cost savings. Several countries have observed these cost savings in the recent past. For example, Kenya and Egypt saved more than $1.5 million per year on International transit costs by having an Internet Exchange Point.
One of the key benefits of having an IXP is that it can lead to lower latency for the end users. This is because for content hosted locally, traffic does not need to go through an incumbent operator.
By having an Internet Exchange Point, ISPs can directly peer with each other to exchange traffic. This would incentivize local content hosting that will lower costs and save on foreign exchange. Moreover, reduced cost savings will encourage more local content development.
By having an Internet Exchange Point significant amount of traffic will remain local and would not have to traverse International networks. This will help lower security violation and also help address any privacy concerns related to the local traffic in Afghanistan.
An aggregate traffic stream is a collection of IP flows that are grouped together for common treatment between two or more points in a network. Packets from all flows in a trunk travel the same path and are subject to the same traffic management policies. The National Internet Exchange of Afghanistan (NIXA) is the neutral connecting point of the ISPs in Afghanistan. Its main purpose is to facilitate exchange of domestic Internet traffic between the peering ISP members. This enables more efficient use of international bandwidth, saving foreign exchange. It also improves the Quality of Services for the customers of member ISPs, by avoiding multiple international hops and thus reducing latency.
