HP-UX IPQoS API Overview

Sessions: Every application that uses the HP-UX IPQoS API must start a session. The function used to start a session is IpqosInitSession(). One of the arguments of this function specifies a session type. There are three types of sessions: IPQOS_SESSION_CONFIG (used for active “set” functions), IPQOS_SESSION_READ (used for passive ”get” functions) and IPQOS_SESSION_STATS (used for functions related to obtaining and resetting statistics). Sessions must be terminated. There are two ways of terminating a session: committing (saving) or aborting (quitting without saving), using IpqosCommitSession() and IpqosAbortSession(), respectively.

See the relevant sections of Chapter 2, “Using the HP-UX IPQoS API,” on page 21, for more information on how the HP-UX IPQoS API uses objects, lists and sessions.

NOTE

The data structures used in HP-UX IPQoS are opaque and need not be an

 

explicit concern of programmers using the API.

 

 

Functional Overview (What You Can Do Using the HP-UX IPQoS API)

There are several types of tasks you can accomplish using the HP-UX IPQoS API functions. There are also several possible ways to group these tasks. The list below groups the tasks in a way that serves the purpose of describing the tasks from a high-level perspective. For example, some common tasks that can be performed on filter and policy objects are discussed together in this guide, to minimize redundancy.

NOTE

The HP-UX IPQoS API manpages group the functions slightly differently,

 

which is appropriate since the purpose of the manpages is to provide detailed

 

reference information. The groupings used in the manpages work best for

 

detailed syntactical descriptions where redundancy is not a concern.

 

 

The following list provides broad groups of functional tasks that can be accomplished using the HP-UX IPQoS API. For each grouping, the text indicates where more information can be found in this guide, as well as the relevant manpages to refer to for more information.

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.
