Product Overview

Cisco ® Bandwidth Quality Manager (BQM) 4.0 is a next-generation network performance management product that helps enable customers to monitor and provision their network for controlled levels of latency and loss performance. The control of network latency and loss is a vital ingredient in delivering maximum performance for networked applications.

• Data centers hosting desktop virtualization applications like Citrix and Web 2.0 services often exhibit poor performance if the network exhibits uncontrolled or intermittently high levels of latency.

• Collaborative applications like Cisco Telepresence require consistent delivery of controlled latency and low jitter in the network.

• Algorithmic trading and distributed grid computing require ultralow levels of network latency and loss (typically less than 5 milliseconds and no packet loss).

Cisco BQM 4.0 implements a broad set of patented and patent-pending traffic measurement and network analysis technologies that give the user unprecedented visibility and understanding of how to optimize the network for maximum application performance.
Cisco BQM is part of the Cisco Network Application Performance Analysis Solution. This solution is a set of tools and services that help customers quickly isolate application performance problems and optimize their networks for current and future applications to help ensure that they meet their information technology performance and cost objectives.
Cisco BQM is now supported on the product family of Cisco Application Deployment Engine (ADE). The Cisco ADE product family is the platform of choice for Cisco network management applications.
Tables 1 and 2 summarize Cisco BQM functions and business benefits.

Table 1. Cisco BQM Functions

Function

Description

Network Service Quality

Cisco BQM measures the loss, latency, and jitter experienced by the actual application traffic by passively observing packets between any two BQM appliances and sending "out-of-band" timing information to a designated BQM appliance. Cisco BQM supports one-way measurements in both directions. To compute absolute one-way measurement, Cisco BQM supports a GPS-based time synchronization interface.

Expected Quality

Cisco BQM calculates in real time the level of loss and queuing delay for each packet across hundreds of configured classes or site interfaces. The Cisco BQM Network Service Indicator condenses this information into a single number, which reflects the performance of each site and between sites relative to the network performance objectives.

Event analysis

Cisco BQM provides event tracing wherein a rolling real-time trace is always kept. If any congestion event is detected, a 10-second section of the trace around the event is recorded for later analysis. Cisco BQM provides analysis capabilities at the site, class, application, conversation, or even packet level. This helps enable rapid pinpointing of the culprit that is causing the service objective violation.

Bandwidth sizing

Cisco BQM recommendations give clear, plain-language guidelines on class and link bandwidth requirements, queue-limit sizing, and policy settings. Each recommendation takes into account the amount of dynamic congestion that applications or classes can tolerate.

Traffic insight

Cisco BQM traffic insight provides a millisecond-level view and real-time analysis of the use of network resources to support the network application environment. Cisco BQM traffic insight identifies traffic microbursts of programmable duration from 5 milliseconds to 1 second, top talkers, listeners, and conversations and reports average link use, packet rate, and packet size distribution.

Quality alarms

Cisco BQM detection and analysis of congestion is made available to external systems through fully configurable Simple Network Management Protocol (SNMP) traps, syslog streaming, and e-mail alerts.

Table 2. Cisco BQM Business Benefits

Function

Description

Increases network application uptime

Cisco BQM helps network managers ensure that network applications are performing by protecting against network congestion in converged WANs. Cisco BQM monitors, analyzes, and recommends corrective actions against network application congestion.

Reduces application downtime and troubleshooting expense

Through its unique ability to monitor and analyze traffic at the micro level, Cisco BQM diagnoses traffic-induced performance problems that many competing tools miss or misdiagnose.

Mitigates risk of making expensive bandwidth upgrade decisions

Cisco BQM determines whether a bandwidth upgrade or quality of service (QoS) or traffic management policy is the preferred action based on the unique algorithms of Cisco BQM. These algorithms take into account whether an upgrade action may result in no improvement to network quality.

Builds on investment made in Cisco QoS infrastructure

Cisco BQM models Cisco router QoS mechanisms, so network managers can unleash the power of QoS without having to deploy yet another packet-processing appliance.

Availability

Cisco BQM 4.0 will be available on the Cisco ADE 1010 and 2120 Series on October 15, 2007, and Cisco ADE 2130 and 2140 on October 31, 2007. Customers can order these products and fully attached services through their normal sales channels beginning October 5, 2007.

Ordering Requirements

Cisco BQM 4.0 is offered on the Cisco Application Deployment Engine. Cisco ADE is a high-performance platform for Cisco network management applications. Customers can select the Cisco ADE platform that meets their application needs. Additional information can be found at http://www.cisco.com/go/ade.
Cisco BQM 4.0 is available on the Cisco ADE 1010, Cisco ADE 2120, Cisco 2130, and Cisco 2140 Series. Cisco BQM 4.0 is also supported on the Cisco BQM 1180 engine.
Table 3 provides part numbers for ordering. Please note that Cisco BQM 4.0 features a base software license for monitoring 10 sites. Additional bandwidth processing licenses can be procured based on the amount of bandwidth that needs to be monitored. Cisco BQM 4.0 software is supported on the Cisco ADE 1010, 2120, 2130, and 2140 Series.
The Cisco ADE 1010 Series is the entry-level product, which provides for a single Gigabit Ethernet monitoring port. The Cisco ADE 2120 Series can be ordered with either fixed ports of 10/100/1000 Mbps or in a modular version. The modular version of the Cisco ADE 2120 Series can be configured with combinations of 1000BaseSX or LH (optical) Small Form-Factor Pluggables (SFPs) or 1000BaseT (electrical) SFPs. The ADE 2130 Series supports four Gigabit Ethernet in fixed RJ-45 ports or modular configurations using the above-mentioned SFPs. The ADE 2140 Series supports two 10-Gigabit Ethernet ports. The 10-Gigabit Ethernet ports are modular in nature and supports 10 Gigabit Small Form-Factor Pluggables (XFP).
