The Killer Network Service is a suite of software and hardware solutions developed by the company Rivet Networks. This is introduced to optimize network performance for online gaming and other high-bandwidth applications.


The Killer Network Service includes a range of products, such as network interface cards, wireless adapters, and software applications. They are needed to prioritize gaming traffic over other network traffic.

The Killer Network Service uses a technology called “Quality of Service” (QoS) to manage network traffic. It ensures that gaming traffic receives priority over other types of traffic.

This is accomplished by identifying and prioritizing gaming traffic. This is done while slowing down or delaying other non-critical traffic, such as file downloads or streaming videos.
