21 oriented protocol designed to solve issues present in UDP and TCP, particularly
22 for real-time and multimedia (streaming) traffic.
26 implementation, this is the TCP-like CCID2 (RFC 4341). Additional CCIDs, such as
27 the TCP-friendly CCID3 (RFC 4342), are optional.

46 For more up-to-date versions of the DCCP implementation, please consider using
57 and a priority-based variant (DCCPQ_POLICY_PRIO). The latter allows to pass an
59 a higher packet priority (similar to SO_PRIORITY). This ancillary data needs to
62 	cmsg->cmsg_level = SOL_DCCP;
63 	cmsg->cmsg_type	 = DCCP_SCM_PRIORITY;
64 	cmsg->cmsg_len	 = CMSG_LEN(sizeof(uint32_t));	/* or CMSG_LEN(4) */
71 lowest-priority packet first. The default value for this parameter is
82 DCCP_SOCKOPT_GET_CUR_MPS is read-only and retrieves the current maximum packet
85 DCCP_SOCKOPT_AVAILABLE_CCIDS is also read-only and returns the list of CCIDs
89 built-in CCIDs.
91 DCCP_SOCKOPT_CCID is write-only and sets both the TX and RX CCIDs at the same
113 always cover the entire packet and that only fully covered application data is
129 The following two options apply to CCID 3 exclusively and are getsockopt()-only.
140 On unidirectional connections it is useful to close the unused half-connection
141 via shutdown (SHUT_WR or SHUT_RD): this will reduce per-packet processing costs.
163 	The number of times a general DCCP packet is retransmitted. This has
168 	Default CCID for the sender-receiver half-connection. Depending on the
172 	Default CCID for the receiver-sender half-connection; see tx_ccid.
177 	Values in the range Wmin = 32 (RFC 4340, 7.5.2) up to 2^32-1 can be set.
184 	The timeout between subsequent DCCP-Sync packets sent in response to
185 	sequence-invalid packets on the same socket (RFC 4340, 7.5.4). The unit
186 	of this parameter is milliseconds; a value of 0 disables rate-limiting.
201 Per-route rto_min support
202 	CCID-2 supports the RTAX_RTO_MIN per-route setting for the minimum value
210 	CCID-3 also supports the rto_min setting: it is used to define the lower
218 because the checksum covers the pseudo-header as per TCP and UDP. Linux NAT
