"Maximum Delay" text box. This function allows the maximum allowed trans-
mission time frame (in milliseconds) of a single packet to be defined. Any packet
requiring a longer time to be transmitted will be fragmented to smaller sections.
This avoids transmission of large, bursty packets that can cause delay or jitter for
real-time traffic, such as
Shaping Classes
The bandwidth of a device can be divided to reserve constant portions of band-
width to predefined traffic types. Such a portion is known as a shaping class. When
not used by its predefined traffic type or owner (for example
be available to all other traffic. However, when needed, the entire class is reserved
solely for its owner. Also, the maximum bandwidth that a class uses can be limited,
even if the entire bandwidth is available.
When a shaping class is defined for a specific traffic type, two shaping classes are
created. The second class is the "Default Class", which is responsible for all the
packets that do not match the defined shaping class, or any other classes that might
be defined on the device. This can be viewed in the "Class Statistics" screen.
