Deliver Fast, Secure, and Available Applications
Web traffic is rarely constant: it has peaks and valleys that can make it difficult to plan for future business growth. Brocade Virtual Traffic Manager is a unique, highperformance software solution that’s mobile, flexible, and scalable. It allows cost-effective scale capacity and move between hardware and deployment platforms as required, and it reduces the strain placed on application infrastructure with network-level buffering, protocol optimizations, and application-specific measures such as dynamic compression and caching. The result is reduced latency, increased capacity, improved availability, and optimized service levels for each end user.
Traffic Manager includes a web-based administration interface that provides powerful real-time and analysis and history for traffic across Traffic Manager clusters. Alternatively, REST, SOAP and SNMP interfaces can be used to integrate the solution into remote management and event monitoring frameworks for automation of ADC deployment, configuration and integration with customer self-service portals.
How Brocade Virtual Traffic Manager Works
Traffic Manager inspects and processes application traffic with full payload inspection and streaming. As requests are received, a range of optimization techniques ensures that requests are presented in the most appropriate manner to the web and application servers. Responses from the application can be compressed, cached, and returned to the client at optimum speed, while freeing up resources on the server. Builtin TrafficScript software controls how individual requests are optimized, routed, and transformed. Traffic management rules may also be created using Java extensions.
Bring New Services to Market More Quickly
ADCs are an important part of the modern application platform. They provide key functionality such as security, centralized authentication, rate shaping and queuing, and content modification to support applications. They also support operations such as the gradual introduction of new servers, session upgrades between application generations, and A/B testing. Their monitoring and debugging capabilities also help deliver reliable applications with predictable performance.
Brocade Virtual Traffic Manager includes TrafficScript scripting software which provides fine-grained control over how traffic is managed. TrafficScript is designed with application developers in mind, making it far more efficient and easy to use than traditional network or event-based solutions. Traffic Manager also provides graphical analysis and management tools to give control over the complete ADC infrastructure.

Increase the efficiency of your systems and boost the throughput of application servers by up to 50%, with intelligent load-balancing and by offloading compute-intensive functions such as SSL and compression. Brocade Virtual Traffic Manager also includes dynamic content caching for enhanced performance.
Lower Costs with Cloud Economics
Reduce costs with flexible licensing. Brocade ADC products are a new breed of ADC that is natively designed for virtualization and cloud portability. As a pure software solution intended for the widest variety of deployments, Brocade Virtual Traffic Manager enables a more flexible on-demand application delivery strategy, and provides a common delivery platform that can grow with your business using ADC-as-a-Service.
Brocade Virtual Traffic Manager— Enterprise Edition features an auto-scaling capability to ensure reliable application service delivery by automatically managing traffic changes in real time, distributing traffic among a pool of virtual servers. It can orchestrate the provisioning and rightsizing of applications, helping to migrate traffic across multiple virtual and cloud platforms.
Advanced Event Handling
Configure appropriate responses for key infrastructure events, including email and SNMP alerts, syslog logging and custom user-supplied scripts.
You can limit the total bandwidth (kbits/ sec) a set of connections can use which can be used to stop a popular site or application taking up so much bandwidth other sites or applications become unavailable. This can enable service providers to enforce access limits based on criteria such as account type or location.
Traffic Manager has unmatched scale and performance, and is able to scale-up with the latest generation of multi-core CPUs, and scale out with N+M clustering for reliability and throughput.
Traffic Manager can stores copies of requested data on the Traffic Manager rather than the back end servers, freeing them up to deliver newly requested content. This can reduce the need for additional servers as traffic grows and speed up the response to end user requests.
Traffic Manager can compress content returned to the client rather than have that workload undertaken by the backend servers. Compression of content can result in bandwidth being used more efficiently. Offloading this workload from the back-end servers can enable it to serve requests faster.
Use Traffic Manager to apply business policies to each request: geotargeting, edge authentication, session failover, all with a global view of the application cluster. Content inspection allows rapid web changes such as the insertion of marketing tags, branding changes, and dynamic watermarking, procedures that may be difficult to achieve by modifying the application itself.
RESTful Control API
Allows Traffic Manager to be configured and controlled by a third-party application and simplifies administration of large/ complex configurations. The Control API enables configuration changes to be automated (e.g. In response to an event).
Global Load Balancing
Improve service availability by automatically failing over to an alternative datacenter or cloud deployment in the event of a catastrophic failure. Improve service performance by performancesensitive load balancing and locationbased traffic routing.
Monitor the health and correct operation of servers with built-In and custom checks. Detect failures of servers and errors in applications, and route traffic away from these servers so that the performance of the application is not compromised and the user experience is maintained.
Faster web pages with support for HTTP/2 connections. HTTP/2 is a significant enhancement to the HTTP/1.1 standard: Traffic Manager can automatically negotiate an HTTP/2 connection with the client web browser, which may improve web page load time with techniques such as connection sharing, page request multiplexing and header compression. For even more advanced HTML and web content optimization, the optional Brocade Web Accelerator add-on module is available to create custom optimization profiles for individual applications.
Traffic Manager can use a wide variety of algorithms and techniques and balance load based on different criteria (e.g. can send more requests to higher spec machines). Servers can be drained for easy maintenance/uninterrupted service. The client never has to see a server fail.
Deploy services across multiple sites with location-specific configuration and simplify and the management of services from multiple datacenter locations.
Measures performance and load and gives a graphical representation of the results which can identify bottlenecks and identify where and when high loading occurs which can be useful for identifying future upgrade needs.
Request Rate Shaping
Traffic Manager can restrict the number of requests (per min or sec) to a service, from either all or a set of clients. This can stop a small group of intensive users (including spiders) hogging a service, leading to a poor user experience for all users.
Traffic Manager can scale horizontally and vertically very easily, across IT environments and different forms of infrastructure ensuring that it can always scale up to match and support demand for an application or a service.
Service Level Monitoring
Monitors the performance of a service or application and can issue an alert if it falls below a pre-determined level such as going out of scope of an SLA.
Service Protection Classes
Traffic Manager can enforce an IP black/white list and limit the number of connections to a service. It can also enforce rules on HTTP content (e.g. enforce RFC compliance) and help protect against malicious attacks such as Denial of Service.
Ensures all requests from a client go to the same server, enabling application data to persist throughout a session without using cookies (e.g. an e-commerce shopping basket).
Software or Virtual Appliance
The Traffic Manager is software and is available in a range of form factors and configurations, making it ideal for (private, public or hybrid) cloud and virtualized data center deployment.
Off-loading SSL/TLS key exchanges and decryption to the Traffic Manager frees up the back-end servers use their full resources for generating content and responding to user requests. Decryption on the Traffic Manager allows for deep packet inspection. Content can be re-encrypted for secure forwarding of requests to the back-end infrastructure.
TrafficScript is a sophisticated programming language integrated within the core of Traffic Manager that enables high performance, highly-configurable control of traffic management policies. TrafficScript rules can control all aspects of how traffic is managed and can choose when and where to apply request rate shaping, bandwidth shaping, routing, compression, and caching to prioritize the most valuable users and deliver the best possible levels of service. It can also help parse complex XML data using XPath in order to make informed routing decisions based on embedded content.
TrafficScript also supports the offload and acceleration of the translation between XML variants via XSL Transformations (XSLT). TrafficScript software is even powerful enough to create rules that transform requests and responses, correct invalid requests, apply security filtering and optimization, and allow complex response rewriting.

|Production license keys||Production license keys may be used for any purposes, but only on a single system. Production license keys may be obtained from your Brocade partner. All types of license keys are subject to the Brocade End User License Agreement for Brocade Virtual Traffic Manager, which can be found at http://www.brocade.com/legal/index.page#sales|
|Evaluation license keys||Evaluation license keys may be used to process production traffic during the limited evaluation period. 30-day evaluation licenses Developer Edition software and Evaluation software may be requested at http://www.brocade.com/vADC.|
|Developer Mode||If the software does not have a valid license key, the software will run in “developer mode.” Developer mode enables all of the functionality of Brocade Traffic Manager and imposes a performance limit of 1 Mbps throughput.
Users are allowed to distribute the Brocade vADC software and virtual appliances without a license key (‘Developer Edition’), so that they can be used in test and development environments to facilitate the creation and testing of production services. There is no charge for the Developer Edition, and Brocade does not provide technical support.
|Perpetual Licenses||Perpetual licenses provide a perpetual (non-expiring) license key that may be used on one server. Support and software upgrades are not included with a perpetual license, and require payment of an annual support fee.|
|Subscription Licenses||Subscription licenses allow you to use the software for a period of time (the “term”) and oblige you to pay a periodic subscription fee (monthly) for that term. Subscription licenses include support and maintenance.|
|Performance Bands||Production licenses include a performance rating which specifies the maximum capacity of the software. The performance rating applies to outgoing bandwidth.
Bandwidth capacity is applied to outgoing traffic only, after content compression, and is applied per instance of Brocade Virtual Traffic Manager. It limits the speed at which the Brocade Virtual Traffic Manager reads data from the backend server nodes. If the capacity limit is reached, then outgoing traffic may be delayed momentarily. Connections are serviced in a fair manner.
Connections will not be dropped unless outbound traffic greatly exceeds the bandwidth capacity for a sustained period of time, when no data can be transmitted before the client or server timeouts expire. The host hardware must be adequately specified in order to deliver the desired performance.
|When are requests discarded or timed out?||Client software (web browsers) and server software (e.g. web or application servers) both impose timeouts for connections. If a connection is idle for longer than the timeout period, it is closed. Under heavy, sustained load, responses are processed in a fair manner and partial responses are delivered to ensure that all connections are serviced equally. This means that connections are rarely idle for long periods of time when there is data waiting to be written, so connections are very unlikely to be closed down prematurely due to the bandwidth shaping.|
|Which performance band should I choose?||Evaluation licenses do not restrict performance, and may be used for short periods on production sites to gauge performance requirements.
You can determine how much traffic an existing service is processing using the historical activity graphs, current data from the activity charts, and data available via SNMP and SOAP. The historical activity charts record bandwidth smoothed over 5-minute periods; you should add a margin of 50 to 100 percent for traffic spikes.
When you run with a performance-based license, the Brocade Virtual Traffic Manager software will log a warning and raise an alert to inform any time that it is necessary to limit the performance. Traffic is queued, so your end users will experience a momentary slowdown in your service. You can then upgrade to a higher-capacity license if necessary.
|What does “uncapped” performance mean?||“Uncapped performance” means that the license key does not apply a performance rating, and the software can process traffic as rapidly as the host system allows. Performance examples may be found in the Brocade Virtual Traffic Manager Performance Quick Reference document.|
|What is “non-production” use?||In “developer mode,” software may only be used for non-production use:'
|What happens when a license expires?||Perpetual licenses do not expire. Other licenses issued by Brocade will have an expiration date. Once the expiration date has passed, the software reverts to developer mode, with bandwidth and performance restrictions. Brocade Virtual Traffic Manager software raises warnings and alerts well in advance of expiration, and if a license with an expiration date is used in production, customers should configure the Brocade software to email these warnings to an appropriate account.
The zero-cost licenses that Brocade issues for non-production use can continue to be used at no cost unless Brocade has terminated the relevant license or developer program.
|What does “bound to IP address/MAC address” mean?||Production licenses may be deployed on a single nominated host system only. To this end, they contain either an IP address or a MAC address that identifies the host system, and will only operate on a host with a matching address.
Technical workarounds to deploy the license simultaneously on two or more host systems are in breach of the End-User License Agreement.
|Upgrading and transferring licenses||Production licenses may be transferred between host machines, operating systems and platorms at no charge. Please request an “IP Address Change” form from your Brocade support contact. Production licenses may be upgraded to increase performance capacity or unlock additional features – license upgrades are seamless and do not require a software restart.|
Production licenses may be used for any purposes, but only on a single system.
