NetStream Flows

NetStream Flows

NetStream provides packet statistics based on flows and supports statistics about IP packets (including UDP, TCP, and ICMP packets).

  • For IPv4 packets, IPv4 NetStream defines a flow based on the:
    • Destination IP address
    • Source IP address
    • Destination port number
    • Source port number
    • Protocol number
    • ToS
    • Inbound or outbound interface
    Packets with the same information for all seven parameters (known as 7–tuple information) are marked as one flow.
  • For IPv6 packets, IPv6 NetStream defines a flow based on the:
    • Destination IP address
    • Source IP address
    • Destination port number
    • Source port number
    • Protocol number
    • Traffic class
    • Flow label
    • Inbound or outbound interface
    Packets with the same information for all eight parameters (known as 8–tuple information) are marked as one flow.
