OfficeServ QoS ( Quality Of Service)

OfficeServ Intrusion Detection System is integrated within the OfficeServ MP11 or WIM Modules.

Quality of Service (QoS)

Quality of Service is a key element of the WIM. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic such as voice), and improved loss characteristics.

In short QoS ensures that voice traffic gets priority.

The QoS operates at various layers within the OSI model as outlined below.

• Processes priority for layer 2 frames based on the IEEE specification 802.1p.
• Processes priority for layer 3 packets.
• Processes priority queuing for layer 4 packets and for RTP (Real Time Transport Protocol) packets.

In summary the QoS application sequentially assigns priority to packets entering the switch or by enforcing priority on a specific port and is a fundamental requirement for the transmission of voice across a network.

The WIM module provides Quality of Service based on:
Class of service:
Grouping similar types of traffic eg email, video, voice, large document file transfer together and treating each type as a class with its own level of service priority

Policy Management
Defines how a networks resources are allocated between its clients eg individuals, departments, host computers or applications eg voice

Packet Shaping
Controlling network traffic in order to optimize or guarantee performance, low-latency, and / or bandwidth. Traffic shaping deals with concepts of classification, queue disciplines, enforcing policies, congestion management, quality of service and fairness. The combination of Class of Service, Policy Management and Packet Shaping gives Quality of Service
