3.1.2 Timers

This protocol requires no timers beyond those that are used by its DHCPv4 and DHCPv6 transports, as specified in [RFC2131] and [RFC3315], respectively. These timers and other parameters are summarized here for convenience.

RA: The DHCPv4 retransmission attempts (RA) described in [RFC2131] section 4.1. It is the number of retransmission attempts that an NKPU client makes when sending packets to an NKPU server. The time at which each RA occurs is determined by the RDT. Used only when NKPU packets are transported via DHCPv4.

RDT: The DHCPv4 retransmission delay timer (RDT) described in [RFC2131] section 4.1. It is the maximum amount of time (in seconds) that the NKPU client waits for return packets from NKPU servers before retransmitting. Used only when NKPU packets are transported via DHCPv4.

RT: The DHCPv6 retransmission time-out (RT) described in [RFC3315] section 14. Used only when NKPU packets are transported via DHCPv6.

IRT: The DHCPv6 initial retransmission time (IRT) described in [RFC3315] section 14. Used only when NKPU packets are transported via DHCPv6.

MRC: The DHCPv6 maximum retransmission count (MRC) described in [RFC3315] section 14. Used only when NKPU packets are transported via DHCPv6.

MRD: The DHCPv6 maximum retransmission duration (MRD) described in [RFC3315] section 14. Used only when NKPU packets are transported via DHCPv6.

MRT: The DHCPv6 maximum retransmission time (MRT) described in [RFC3315] section 14. Used only when NKPU packets are transported via DHCPv6.
