Integrated Services (IntServ)

Integrated Services (IntServ) is a networking architecture designed to provide guaranteed Quality of Service (QoS) for data transmissions over the internet. It allows applications that require specific bandwidth, low latency, or consistent performance—like video conferencing or online gaming—to reserve the necessary resources ahead of time. By using a signaling protocol to communicate these needs to the network, IntServ ensures that data packets related to critical applications are prioritized, allowing for a smoother and more reliable user experience, even when the network is busy. Essentially, IntServ helps manage data traffic to meet the specific needs of different applications.
