7.2 NetStream Supported by the AR150/200

The AR150/200 supports the sampling of IPv4, and the packet output in v5, v8, and v9 formats.
Sampling and Statistics of the IPv4 Network Traffic
The AR150/200 supports collection of statistics and sampling of the original traffic of IPv4
packets. These IPv4 packets include unicast and multicast packets, and reverse path forwarding
(RPF) check fails packets. In addition to the destination and source IP addresses, the destination
and source port numbers, the protocol ID, and the inbound or outbound interface, the original
statistics include the source and destination ASs, and the next hop of BGP.
Sampling Methods
The AR150/200 supports four types of sampling methods: fixed packet sampling, random packet
sampling, fixed time sampling, and random time sampling.

Versions of Original Traffic and Aggregated Traffic
The Huawei AR150&200 Series supports three types of output modes: original traffic,
aggregated traffic and Flexible traffic. The original traffic is output in the V5/V9 version, the
aggregated traffic is output in the v8/v9 version, and the Flexible traffic is output in the v9
version.
Statistics Aggregation
AR150/200 supports ten aggregation modes, namely, AS, AS-ToS, protocol-port, protocol-port-
ToS, source-prefix, source-prefix-ToS, destination-prefix, destination-prefix-ToS, prefix,
prefix-ToS.
Aging Methods
The AR150/200 supports four types of aging methods: timeout aging of the active time, timeout
aging of the inactive time, disconnection aging of the TCP connection, overflow aging of the
counting.

Fixed packets sampling
This indicates that one sampling is performed each time a certain number of packets are
received.
Random packets sampling
This indicates that one sampling is randomly performed on a certain packet in the specified
packets.
Fixed time sampling
This indicates that one sampling is performed on packets at a certain interval.
Random time sampling
This indicates that one sampling is randomly performed on packets in the specified period.
Timeout aging of the inactive time
