ABBA Engine
The StreamSense platform uses a unique patented technology based on Per Flow Queuing mechanisms that automatically accelerate application traffic by taking into account instantaneous bandwidth requirements. The ABBA (Application Behavior-Based Acceleration) engine guarantees users maximum application performance and ease of use by analyzing application behavior. Appropriate processing is applied automatically without requiring specific configuration or traffic classification, no matter the variation in the number of users (sessions) or in application behavior (e.g. version changes).
|
Interactive traffic |
|
Thanks to Streamcore's Fast Start mechanism, interactive data streams are accelerated automatically. Within a Citrix, Windows Terminal Server Edition, or encrypted (SSL) session, interactive keystrokes are identified automatically and instantly assigned maximum priority. Even with large data transfers in progress, keystroke fluidity is guaranteed. |
|
Transactional traffic and large data transfer |
|
Contrary to a static QoS engine (e.g. Class of Service on a router), the ABBA Engine's Fair Share mechanisms control competition between users within the growing number of strategic transactional applications. Access to a given application is distributed equitably among all users. |
Advanced QoS
The StreamSense advanced QoS engine gives priority to mission-critical data applications on the network:
- Bandwidth is optimized according to business needs
- Secondary or disruptive traffic (recreational Internet, antivirus or operating system updates, etc.) does not affect performance
Once the critical application has been identified and classified, priority is granted using a business-oriented logic. Administrators simply define the business criticality of each application. They do not need to delve into the complexity of the application profile. (minimum throughput, burst, queuing, etc.)
Once criticality levels are defined, the advanced QoS engine automatically makes sure that the performance ratios are applied for each session. It arbitrates bandwidth allocation whenever demand exceeds capacity on a given link, based on the criticality levels of each active session. Whatever the type of application and no matter the type of application or the number of users present at any time, performance levels are always pre-determined.
Entity Control
WAN access link can be shared between several entities, for instance between Business Units or different customers. With the Entity Control feature, you can define a minimum and a maximum data rate per entity, and then allocate bandwidth between applications and sessions for each entity.
You can therefore deliver differentiated services per entity and guarantee performances according to the type of service level they subscribed to.
VoIP and Video Control
A dedicated control mechanism can be used to guarantee performance of multimedia traffic such as VoIP or Video. While data applications are automatically handled by the ABBA and Advanced QoS engines, multimedia traffic is handled by a reserved bandwidth mechanism (per session or for a group of sessions) which will guarantee a minimum latency and jitter over the WAN.
MPLS Class Control
Using StreamSense over an MPLS network provides advanced control over the Class of Services that can be activated within the service provider routers:
- Visibility over Class of Services usage and traffic classification
- Advanced complementary congestion management and per-session bandwidth allocation
- Optional egress ToS/DSCP field marking to offload routers and add provisioning flexibility
The compression features provide more network bandwidth while the QoS engines ensure that business applications have the throughput they need to run properly. Streamcore's solutions use this winning combination to guarantee response times and deliver continuously improved performance to users.
Despite the implementation of prioritization mechanisms, links may still be under-sized in terms of meeting the needs of business applications. In this case, compression can increase capacity without modifying the existing infrastructure. The average gain in throughput is between 1.5 and 4, and can be as high as 10 for certain types of traffic.
Compression is implemented on an end-to-end basis between two StreamGroomers. The appliances generate a shared dictionary and can then exchange labels that symbolize the repetitive sequences carried over the WAN. They can then deliver decompressed traffic over the LAN. This method is transparent for servers and client computers, and works on all IP flows.

Encryption
The encryption option can be activated to secure communication between two sites equipped with StreamGroomers. Once secured and authenticated communications have been established between the SGM and StreamGroomers, an innovative centralized key management system allows encryption to be turned on and off with a single parameter.
WAN Load Balancing
When two paths are available between sites equipped with StreamGroomers, WAN load balancing can be activated in order to manage dual access link bandwidth in an optimized way. For instance, WAN Load balancing can be provisioned when a backup link is used only as a fail-over in order take advantage of the available bandwidth.
