name: PFF
full_form: Protocol Field Flag
context: (e.g., using COPS MPLS [40]), or set up dynamically using CR-LDP [37] or RSVP-TE [38]. As part of this process of setting up the LSPs, all the intermediate transit routers are provisioned to provide the desired per-hop behaviour (i.e., scheduling treatment and in some cases, drop precedence for each DS code point). By providing consistent behaviour to packets belonging to the same class of service in each transit node which is part of an LSP, the overall quality of service in that LSP is achieved. This is consistent with the approach described in [31]. - The operator decides how many classes of service there will be supported in the UTRAN, and also how classes of service map to an LSP (i.e., one or more). - An IP packet is mapped to the LSP with appropriate class of service based on two things: the DS code point marking in the IP header of the packet, and the FEC that the packet belongs to, (i.e. the destination IP address in the IP header). This is also consistent with [31]. - IP
description: The Protocol Field Flag (PFF) is a one-bit field within the PPP Multiplexed Frame Option Over HDLC, indicating whether the PPP Protocol ID of the subframe follows the subframe length field. It plays a crucial role in determining the presence or absence of the protocol field for each subframe.
explanation: The context describes PFF as a specific bit within a larger data structure (PPP Multiplexed Frame Option Over HDLC), outlining its function and value interpretation (0 or 1). This aligns with the definition of a 'Field' entity type, which represents a distinct part of a data structure carrying specific information.
