| Step 1: Receive (Labeled Big Data Traffic_, Gateway_number, Factor_Vol, |
| Security_Servic_); |
| Function for getting Big Data traffic by Name_node |
| Where: |
| Labeled Big Data Traffic_ traffic label (TL), Data (D), |
| Gateway_number Value of Gateway sending labeled Big Data traffic (GN) |
| Factor_Vol Volume factor type (V): |
| Assumptions: |
| (i) Real time data is assigned different label than file transfer data and |
| thus the label value should indicate the Volume size |
| (ii) Real time data are usually assumed less than 150 bytes per packet. |
| Security_Service_ Confidentiality (C), Authentication (Auth) are examined by |
| the label value of each traffic. |
| Step 2: Forward (Data_node_, Security_Service) |
| Function for distributing the labeled traffic for the designated data_node(s) with |
| security service assignment: |
| Security_service required or applied? |
| True then go to data_node(s) assigned to analyze and process security services. |
| Step 3: Data_node_Checking (packet_headers, labels) |
| Performs header and label information checking: |
| Label_checking performs label examination |
| Header_checking performs header examination: |
| Assumptions: secured data comes with extra header size such as ESP header |
| Step 4: Go to step 1 |
