This object applies when circuit emulation of the client
protocol is used. It allows the management client to
configure the size of the transmit buffer on the client
port. A value of 0 implies that this object does not apply
to this interface.
Controlling the size of the transmit buffer on a client
port may be essential in scenarios where packet streams
from various client ports are aggregated onto a single
trunk port. The latency associated with an elementary
stream received on a client port, from the trunk port is
influenced by the nature of other elementary streams in
the aggregate. For example, a giant packet in one stream
will increase latency in processing packets in other
elementary streams. The size of the transmit buffer on
the client port must be configured proportional to this
expected latency. Increasing the buffer size when latency
is higher helps in reassembly of fragmented packets before
transmitting them to the client device.
Note that increasing the buffer size results in higher
latency even when the elementary packet stream is not
subject to high jitters. Refer to the platform specific
documentation for guidelines on configuring this buffer
size.
