Optimised Application Performance & Wan Cost For Converged IP Voice, Data and Video Networks
Optimising bandwidth has always been central to controlling the Total Cost of Ownership (TCO) of an enterprise Wide Area Network (WAN). Even with the industry's steady improvements in bandwidth price/performance, IT managers have constantly been pressured to get “more out of what you've got.”
Now, as the enterprise begins to exploit the efficiency of IP across converging voice, data, and video applications, the mandate is growing. Voice over IP (VoIP) and IP video need specific performance guarantees. Business applications, like ERP and Citrix, must meet strict response time standards. Each of these applications must perform, while Web and Internet traffic aggressively compete for bandwidth. As a result, the enterprise IP WAN bar is moving from basic bandwidth optimisation to one that assures IP application performance – on a per session and/or per user basis.
The Converged Traffic Manager(TM) (CTM) is the industry's first application-aware performance management solution to enable the toll-quality VoIP, jitter-free IP video, and business-IP response times that are crucial to enabling the lower cost and higher value of IP convergence.
The CTM integrates best-of-breed traffic monitoring, traffic management, compression and caching with advanced application layer visibility and control to assure WAN efficiency and application performance for converging IP voice, data and video applications. It is easily deployed as a seamless overlay to an existing IP network.
Key Advantages

- Precise and granular per session, per user application performance guarantees
- WAN optimisation with bandwidth utilisation that can exceed 95%
- Integrated compression and caching to expand bandwidth, accelerate response times
- Investment protection through ease of integration with existing applications and networks
- Centralised Converged Policy Manager (CPM) configuration, management and reporting
Traffic Monitoring
Continuous, Real-time Traffic Monitoring and Discovery Before traffic management policies can be applied, the network administrator must first understand how the network is being used. QoSWorks provides real-time monitoring of over 1400 applications, creating a window into all of the voice, video and data traffic traversing the network. User-friendly charts and reports make it easy to see how much bandwidth each user and application is consuming. This gives administrators clear direction on how to initially set and later adjust policies to best protect application performance.Advanced Traffic Management
All Converged Access products are based on the QoSWorks traffic management system to provide granular and accurate IP application performance guarantees. Application specific policies are enforced by a tightly integrated system of bandwidth management techniques (shown below). Many of these techniques are combined to bring precise performance guarantees to individual application sessions or flows.Selective Compression and Caching
The Converged Traffic Manager (CTM) offers superior cost savings with a compression and caching solution that can expand WAN bandwidth by as much as 10X. The benefit to the enterprise is measurable as bandwidth is freed to improve application performance while delaying costly bandwidth upgrades.VoIP Services
Toll-Quality for Each Call There are three primary issues that impact VoIP quality: delay, jitter and packet loss. If there is too much delay, the conversation sounds like a two-way radio conversation where one party has to wait for the other to finish before they can speak. Variations in delay, or jitter, will cause choppy communications. Packet loss, generally caused by network congestion, will result in unintelligible speech.Integrated Security
Security is typically provided at many levels, with the highest level provided using Application Layer Gateways (ALG). This is important for the many protocols, including SIP, H.323, FTP etc. that use dynamic ports to establish connections between computers. While it is possible to leave a range of ports open so these connections can get through, it is far more secure to inspect the application packets and dynamically open only the ports requested by the application.Other Products in this category:
