Module: DOCS-QOS3-MIB
OID (symbolic): DOCS-QOS3-MIB::docsQosPHSField
OID (numeric): 1.3.6.1.4.1.4491.2.1.21.1.10.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This attribute indicates the Payload Header suppression field defines the bytes of the header that must be suppressed/restored by the sending/receiving device. The number of octets in this attribute should be the same as the value of PHSSize.
What is docsQosPHSField?
This object specifies which bytes of the packet header should be suppressed or restored during Payload Header Suppression (PHS) processing in cable modem systems, with the field size matching the associated PHS Size. PHS reduces overhead by omitting redundant header bytes on compression-capable connections. Cable operators use this to fine-tune header compression efficiency for specific QoS flows carrying predictable traffic.
