Policy Blocks

res[ervation] b1[suffix]

Reserves the specified amount of bandwidth, b1[suffix], for outbound traffic matching any filter used by the policy. Whenever there is less traffic in this class than the reservation specified, unused bandwidth is available for other traffic.

The b1 parameter specifies the numeric value of the reservation bandwidth.

The [suffix] parameter can be either a percent sign (%) or one of the letters k, K, m, or M. The % is mutually exclusive with k, K, m, or M. The % specifies a percentage of the associated adapter’s allowable bandwidth capacity.

The valid range for b% is between 0 and 100 inclusive.

The k, K, m, and M options represent a shorthand to avoid typing zeros. Only one of these options can be specified per instance. The k and K options both represent 1000 bits/second. The m and M options both represent 1,000,000 bits/second. The range for b[k,K,m or M] is from 0 to the full bandwidth of the associated adapters. If [suffix] is not specified, b1 is interpreted as bits/second. For example, the following are all equivalent to 5000 bits/second:

•5000

•5k

•5K

No white space is allowed between b1 and the [suffix].

The default reservation bandwidth if none is specified is 0. When res is 0, the matching traffic class is always dropped. For traffic classes that you don’t want to allow on the network, you can either specify res 0, or not specify a res value and use the default of 0.

The sum of the reservations for all policies associated with a specific adapter cannot be greater than the adapter’s full bandwidth minus the implicit default flow’s rate. For example, since the implicit default flow uses 80Kbps, you can reserve only the adapter’s full bandwidth minus the 80Kbps reserved by the implicit default flow.

In the case of VLANs, the aggregate of the reservations of policies of VLANs that are based on the same physical adapter, and the policies of the base adapter itself, cannot exceed the speed of the physical adapter minus the 80Kbps reserved by the implicit default flow.

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.
