Network Traffic QoS Simulation

This problem simulates a network management system processing network packets with various traffic types. The system applies a Quality of Service (QoS) policy depending on the traffic type. For each packet, the program should output a processing log that includes the traffic type, the corresponding QoS policy, the source IP, and the destination IP.

The known traffic types and their QoS policies are:

• HTTP - High
• FTP - Medium
• Streaming - Low

For any other traffic type, the QoS policy is "Unknown". Additionally, the program should maintain a count of processed packets for each traffic type and, after processing all packets, output these aggregated counts in the order that each traffic type first appeared.

Note: All formulas (if any) must be in LaTeX format. However, this problem does not contain any mathematical formulas.

inputFormat

The first line contains an integer N representing the number of packets. Each of the following N lines contains three values separated by spaces: a string representing the traffic type, a source IP address, and a destination IP address.

Example:

3
HTTP 192.168.0.1 192.168.1.1
FTP 192.168.0.2 192.168.1.2
Unknown 192.168.0.3 192.168.1.3

outputFormat

For each packet, output a line in the format:

Processing packet: <traffic_type>, QoS: <qos>, Source: <source_ip>, Destination: <destination_ip>

After processing all packets, output the aggregate counts for each traffic type on separate lines, in the order of their first appearance. Each line should be in the format:

<traffic_type>: <count>

## sample

3
HTTP 192.168.0.1 192.168.1.1
FTP 192.168.0.2 192.168.1.2
Unknown 192.168.0.3 192.168.1.3

Processing packet: HTTP, QoS: High, Source: 192.168.0.1, Destination: 192.168.1.1
Processing packet: FTP, QoS: Medium, Source: 192.168.0.2, Destination: 192.168.1.2
Processing packet: Unknown, QoS: Unknown, Source: 192.168.0.3, Destination: 192.168.1.3
HTTP: 1
FTP: 1
Unknown: 1
