IPv6 NetStream overview
Conventional traffic statistics collection methods, like SNMP and port mirroring, cannot provide precise
network management because of inflexible statistical methods or high cost (dedicated servers are
required). This calls for a new technology to collect traffic statistics.
IPv6 NetStream provides statistics on network traffic flows and can be deployed on access, distribution,
and core layers.
The IPv6 NetStream technology implements the following features:
•
Accounting and billing—IPv6 NetStream provides fine-gained data about the network usage based
on the resources such as lines, bandwidth, and time periods. The Internet service providers (ISPs)
can use the data for billing based on time period, bandwidth usage, application usage, and quality
of service (QoS). The enterprise customers can use this information for department chargeback or
cost allocation.
•
Network planning—IPv6 NetStream data provides key information, for example the autonomous
system (AS) traffic information, for optimizing the network design and planning. This helps
maximize the network performance and reliability when minimizing the network operation cost.
•
Network monitoring—Configured on the Internet interface, IPv6 NetStream allows for traffic and
bandwidth utilization monitoring in real time. Based on this, administrators can understand how the
network is used and where the bottleneck is, better planning the resource allocation.
•
User monitoring and analysis—The IPv6 NetStream data provides detailed information about
network applications and resources. This information helps network administrators efficiently plan
and allocate network resources, and guarantee network security.
IPv6 NetStream basic concepts
IPv6 flow
IPv6 NetStream is an accounting technology to provide statistics on a per-flow basis. An IPv6 flow is
defined by the 7-tuple elements: destination address, source IP address, destination port number, source
port number, protocol number, type of service (ToS), and inbound or outbound interface. The 7-tuple
elements define a unique flow.
