Application Scenarios for NetStream

Application Scenarios for NetStream

Inter-AS NetStream

Figure 3-24 Schematic diagram for inter-AS NetStream

A NetStream packet can carry either original AS attribute or peer AS attribute for BGP routes. Original and peer AS types are mutually exclusive. A device advertises BGP routes within an original AS or transparently transmits BGP route information from a peer AS to a local AS.

Inter-AS NetStream monitors and collects statistics about traffic sent by the original or peer AS to a local AS, which provides reference for network deployment.

For example,
  • Traffic from AS 800 passes through AS 700, AS 900, and then AS 600 before reaching AS 500. If the NetStream function is enabled in AS 600 and NetStream packets carry the peer AS attribute, traffic from AS 700 and AS 900 to AS 600 is monitored.
  • Traffic sent by AS 800 and AS 100 reaches AS 500 through AS 200, AS 300, and AS 400. If the NetStream function is enabled for AS 300 and NetStream packets carry the original AS attribute, traffic sent by AS 800 and AS 100 to AS 500 is monitored.

IP Address Prefix-Based Charging for ISPs

Figure 3-25 IP address prefix-based charging for ISPs

A specific IP address prefix is assigned to each ISP network. NetStream destination-prefix aggregation helps collect statistics about traffic traveling to ISP networks can be collected based on destination IP addresses and masks. Traffic with different destination IP addresses and masks are charged separately.

Analyzing the Service Mode on an MPLS Network

Figure 3-26 Schematic diagram for the analysis of the service mode on an MPLS network

NetStream is deployed on a user interface of a PE to collect statistics about traffic exchanged between an MPLS network and an IP network. The statistics helps provide an accounting scheme.

NetStream is deployed on a network interface on the PE and P to collect statistics about MPLS packets. The MPLS service mode can be pinpointed.
