QoS Enforcement for VSX (Lightweight QoS) provides the ability to control the network quality of service in the VSX network environment. QoS is based on the Differentiated Services architecture and allows assigning different transmission characteristics to different classes of service.
Differentiated Services is a computer networking architecture that specifies a simple, scalable and coarse-grained mechanism for classifying, managing network traffic and providing quality of service (QoS) guarantees on modern IP networks. Differential services can, for example, be used to provide low-latency, guaranteed service (GS) to critical network traffic such as voice or video while providing simple best-effort traffic guarantees to non-critical services such as web traffic or file transfers.
The major characteristics that are controllable by QoS are latency and bandwidth allocation. QoS is designed to provide QoS functionality with minimal impact on performance. QoS works seamlessly with Check Point Performance Pack.
The VSX network usually includes various types of traffic such as:
Without QoS Enforcement, all these different traffic types are given equal priority on the VSX Gateway and are handled in a simple FIFO (first in-first out) manner. When the VSX Gateway is congested, all traffic types suffer the same degree of latency and drops. Also, high-volume traffic may starve other types of low-volume traffic.
With QoS, the special requirements of each traffic type can be met. For example:
