Configuring Header De-Duplication and Frame Cut-
Through
Note:
Header De-Duplication is supported for IP-20C and IP-20S.
For IP-20E, Header De-Duplication is planned for future
release.
Header De-Duplication enables operators to significantly improve Ethernet
throughout over the radio link without affecting user traffic. Header
De-Duplication can be configured to operate on various layers of the protocol
stack, saving bandwidth by reducing unnecessary header overhead. Header
De-duplication is also sometimes known as header compression.
Note:
The Header De-Duplication configuration must be identical
on both sides of the link.
Using the Frame Cut-Through feature, frames assigned to queues with 4th
priority pre-empt frames already in transmission over the radio from other
queues. Transmission of the pre-empted frames is resumed after the
cut -through with no capacity loss or re-transmission required.
