Riverbed Classification and QoS Engine
Business Overview
A WAN optimization solution needs to classify applications accurately and apply quality of service rules and policies that help ensure the high performance of business-critical applications. Controlling applications effectively requires visibility to determine which applications need to be protected, which applications should be contained, and how much bandwidth should be allocated to each.
Most WAN optimization vendors use a combination of deep packet inspection (DPI) and basic QoS schedulers, which fail to enhance applications that are sensitive to latency and packet loss, including business VoIP, video, and interactive Web applications. This combination also does little for recreational applications that port-hop, or that change and mask protocols.
Technical Overview
Riverbed QoS delivers a unique combination of best-of-breed classification and an advanced, unique scheduling technique based on Hierarchical Fair Service Curve (HFSC). This combination addresses the need for the accurate classification of applications, the allocation of minimum and maximum bandwidths, and the ability to prioritize applications based on their latency sensitivity, which is not possible with most other approaches.
Riverbed AppFlow – Application Classification Engine
The Riverbed AppFlow engine utilizes a variety of techniques, often in combination, to maximize the accuracy and efficiency of its real-time network traffic classification. These techniques include port-based classification, application signature matching, protocol dissection, future flow registration, behavioral classification and others, to identify applications that may hop ports or be otherwise hard to detect. The AppFlow engine can identify and classify hundreds of common enterprise applications, and is configurable to classify thousands of custom applications. This ensures that critical applications like web, voice, and video are protected, while recreational applications are contained.
The tables below list the categories and applications classified by the DPI engine. Although these applications are mapped to default classes, customers can, of course, customize by combining these classes with other optimization policies.
Business and Productivity Applications
Riverbed Hierarchical Fair Service Curve (HFSC) Scheduling
The Riverbed HFSC scheduler not only addresses the allocation of minimum and maximum bandwidth (as many products do), but also prioritizes and schedules applications based on their latency sensitivity, thus eliminating jitter and starvation of applications. Steelhead appliances can apply these state-of-the-art techniques while remaining compatible with QoS enforcement on routers and other devices.
