Overview

HP-UX IPQoS brings an HP-UX host into conformance with the Internet Engineering Task Force (IETF) Differentiated Services (DiffServ) model on outbound HP-UX traffic.

HP-UX IPQoS provides differentiated classes of service on outbound HP-UX host traffic by performing traffic classification and traffic conditioning actions. Through traffic classification (packet filtering) and traffic conditioning (packet metering, shaping and marking), important traffic classes can take bandwidth away from less important classes, up to user-specified limits.

HP-UX IPQoS loads a configuration into the kernel, that contains user-supplied definitions of traffic classes (filters) and traffic-handling instructions (policies) assigned to configured adapters on the host.

Note:

HP-UX IPQoS conformance to the IETF DiffServ model applies only to outbound traffic on an HP-UX host.

Benefits

HP-UX IPQoS helps the network support business objectives, while simultaneously helping to minimize the cost of managing network resources. It helps keep network costs down by using bandwidth more efficiently and by eliminating the need for overprovisioning as a result of expanding the usefulness of the existing infrastructure.

HP-UX IPQos helps address several problems including the following:

  • Managing the explosive growth of network traffic over the last several years, in large part, due to the explosive increases in Internet usage.
  • Meeting the ever-increasing need for guaranteed communication as traditional uses of the network now compete with mission critical applications.
  • Improving upon the best effort service IP networks provide by default to all traffic types. Just keeping the network up and running is insufficient, because some traffic requires higher performance.
  • Offering a cost-effective alternative to overprovisioning, which expands and upgrades infrastructure equipment capacity to try to keep ahead of peak usage, rather than strategically addressing typical usage. The capital investments needed to keep congestion and queuing delays within reasonable limits during peak times are much higher than those needed to keep up with average use.

Features
The following is a list of features HP-UX IPQoS delivers:

  • Conforms to the IETF DiffServ model: can apply to specified traffic classes:
    - reservation and maximum allowed traffic bandwidth allocations
    - DSCP and VLAN marking
  • Supports traffic classification (filtering) on any of the following packet attributes:
    - IP address (source, destination, or both; range or individual; numerically or by host name)
    - transport port numbers (source, destination, or both; range or individual; numerically or by service name)
    - transport protocol number (only tcp or udp are currently supported)
    - network protocol number (Ethertype)
    - DSCP value
    - Destination physical (MAC) address
  • Supports traffic classification (filtering) on IPv4 and IPv6 addresses.
  • Provides a simple configuration file format
  • Provides a simple utility for all administrative tasks (ipqosadmin)
  • Provides an API for (optional) programmatic HP-UX IPQoS control
  • Provides statistics for configured adapters, policies, and filters
  • Requires no changes to existing applications
  • IEEE802.3ad (Auto Port-aggregation) compatible
