Traffic Control

Posted on by lechuck park

This image shows a network traffic control system architecture. Here’s a detailed breakdown:

  1. At the top, several key technologies are listed:
  • P4 (Programming Protocol-Independent Packet Processors)
  • eBPF (Extended Berkeley Packet Filter)
  • SDN (Software-Defined Networking)
  • DPI (Deep Packet Inspection)
  • NetFlow/sFlow/IPFIX
  • AI/ML-Based Traffic Analysis
  1. The system architecture is divided into main sections:
  • Traffic flow through IN PORT and OUT PORT
  • Routing based on Destination IP address
  • Inside TCP/IP and over TCP/IP sections
  • Security-Related Conditions
  • Analysis
  • AI/ML-Based Traffic Analysis
  1. Detailed features:
  • Inside TCP/IP: TCP/UDP Flags, IP TOS (Type of Service), VLAN Tags, MPLS Labels
  • Over TCP/IP: HTTP/HTTPS Headers, DNS Queries, TLS/SSL Information, API Endpoints
  • Security-Related: Malicious Traffic Patterns, Encryption Status
  • Analysis: Time-Based Conditions, Traffic Patterns, Network State Information
  1. The AI/ML-Based Traffic Analysis section shows:
  • AI/ML technologies learn traffic patterns
  • Detection of anomalies
  • Traffic control based on specific conditions

This diagram represents a comprehensive approach to modern network monitoring and control, integrating traditional networking technologies with advanced AI/ML capabilities. The system shows a complete flow from packet ingress to analysis, incorporating various layers of inspection and control mechanisms.

Switching/Routing L2-L7

Posted on by lechuck park

From Gemini with some prompting
The image illustrates how network switches differentiate packets from Layer 2 (L2) to Layer 7 (L7) based on the OSI model. The central image depicts a switch or router forwarding a specific packet, highlighting the criteria used for identification at each layer.

Layer-by-Layer Explanation:

L2 Switch:

  • Distinguishing criteria: MAC address
  • Function: Frame switching
  • Key feature: Uses hardware-based switching for fast performance
  • Limitation: Does not consider network layer information

L3 Switch:

  • Distinguishing criteria: IP address
  • Function: Packet switching, routing
  • Key feature: Supports inter-VLAN routing and network segmentation
  • Limitation: Does not utilize L4 and L7 information

L4 Switch:

  • Distinguishing criteria: TCP/UDP port number
  • Function: Packet switching, load balancing
  • Key feature: Facilitates application-specific traffic control and load balancing
  • Limitation: Disregards L7 information

L7 Switch:

  • Distinguishing criteria: HTTP URL, payload
  • Function: Application gateway, content filtering
  • Key feature: Offers granular control over application-level traffic and security
  • Complexity: Requires more complex configuration and management
