well, a firewall could do it, but an Intrusion Prevention System is the more obvious answer.
IPS

IPS (Intrusion Prevention System)- A dedicated device or software running on a host that automatically reacts to any unauthorized attempt to access an organization's secured resources on a network or host. IPS is often combined with IDS, however IDS do not automatically make changes to block or overt traffic.
Traffic analysis is a method used by attackers to monitor and analyze network traffic to gather information about its patterns, volume, and behavior. This can help attackers identify vulnerabilities in the network and plan future attacks more effectively. It can also be used for legitimate purposes, such as optimizing network performance and security.
Network-based Intrusion Prevention (NIPS): monitors the entire network for suspicious traffic by analyzing protocol activity.A reactive NIDS can also be called a network intrusion prevention system (NIPS).

A network traffic analyzer is used for analyzing and monitoring the use of network traffic for many devices. Network Traffic Analyzer is also used to monitor the wireless network performance.

This is known as "stateful" filtering - When firewalls are aware of the traffic state as well as the content of the packets.
Tracing network traffic requires a network monitor, protocol analyzer, or packet sniffer.
