meter

meter A device that measures the rate of a traffic stream selected by a classifier. The instantaneous state of this process can be used to affect the operation of a marker, shaper, or policer.

per hop behavior (PHB) The externally observable forwarding treatment applied at

aDS-compliant node to a collection of packets with the same DSCP.

policer A device that as part of shaping discards (drops) packets within a traffic stream, in accordance with the state of a corresponding meter enforcing a traffic profile.

policy block In the context of an HP-UX IPQoS configuration file, defines a specific policy to apply to traffic which matches any filters associated with the policy.

Quality of Service (QoS) A set of service requirements to be met by the network while transporting a flow. Implies a mechanism to deliver better than best-effort service to network traffic.

service level agreement (SLA) A service contract between a customer and a service provider that specifies the forwarding service the customer is to receive. It can include traffic conditioning rules.

service provisioning policy A policy that defines how traffic conditioners are configured on DS boundary nodes, and how traffic streams are mapped to DS behavior aggregates to achieve a range of services.

shaper A device that delays packets within a traffic stream to cause it to conform to some defined traffic profile, usually to reduce load peaks.

traffic classification The process where packets in a traffic stream are filtered into distinct classes (groups) based on the content of a part of the packet header.

traffic conditioning The process where packets in a traffic stream are subject to control functions including metering, marking, policing and shaping.

traffic shaper See shaper.

traffic profile A description of the temporal properties of a traffic stream. For example, rate and burst size.

UX IPQos Software specifications

HP-UX IPQoS is a sophisticated software solution designed to enhance the network performance of HP's Unix-based operating system, HP-UX. This software focuses on Quality of Service (QoS) mechanisms that ensure efficient bandwidth utilization and prioritize network traffic to meet the demands of various applications.

One of the main features of HP-UX IPQoS is its ability to define traffic priorities. Administrators can classify traffic into different priority levels, allowing critical applications to receive the bandwidth they need while less important traffic can be deprioritized. This feature is essential in environments where bandwidth is a limited resource, ensuring that business-critical processes maintain their performance even during peak usage times.

The software employs advanced traffic shaping techniques that allow the management of data flow in the network. By controlling the rate of traffic and smoothing out bursts, IPQoS helps prevent network congestion, leading to a consistently reliable user experience. In addition, it can manage both inbound and outbound traffic, ensuring optimal performance in various network scenarios.

Another significant characteristic of HP-UX IPQoS is its integration with other network management tools. It operates seamlessly with HP’s Network Management Suite, providing a holistic view of network performance. This integration facilitates easier troubleshooting and monitoring, as administrators can correlate data from different sources for comprehensive insights.

Moreover, HP-UX IPQoS supports various protocols, including DiffServ and MPLS. By adhering to these standards, it positions itself as a versatile tool that can operate in diverse network environments, providing flexibility and ease of deployment. Additionally, the software supports policy-based management, enabling organizations to implement specific rules tailored to their network requirements.

Security is also a critical focus of HP-UX IPQoS. The software provides mechanisms to enforce traffic policies while safeguarding against potential threats. By ensuring that only authorized traffic flows through the network, it minimizes the risk of attacks and data breaches, contributing to a more secure IT environment.

The user interface of HP-UX IPQoS is designed for ease of use, allowing network administrators to configure settings, monitor performance, and generate reports without extensive training. This user-friendliness accelerates the deployment process and enhances the overall management of network resources.

In summary, HP-UX IPQoS is a robust and versatile network management solution that brings substantial benefits to organizations looking to optimize their network performance. With its traffic prioritization features, integration capabilities, support for industry standards, and focus on security, it stands out as an essential tool for maintaining effective and secure network operations in a dynamically changing IT landscape.
