Algorithm 1: Packet Parser Algorithm

Input: Packet Capturing Files (PCAP)

Output: TCP, HTTP as output files

Step 1: Set $P=\{p_1, p_2, \dots , p_n\}$, where P is a packet

Step 2: $Filter \left(P\right)=P^{\prime }$

Step 3: Compute PCAP from $P^{\prime }$, where $P^{\prime }=\left(\mathrm{IP},\mathrm{TCP},\mathrm{HTTP},\dots ,n\right)$

Step 4: Select NF from PCAP, where NF is the required network flows

Step 5: Display/select HTTP + TCP
