53 depends on IP_DCCP_CCID3 && EXPERIMENTAL
54 ---help---
55 Use higher lower bound for nofeedback timer expiration.
56
57 The TFRC nofeedback timer normally expires after the maximum of 4
58 RTTs and twice the current send interval (RFC 3448, 4.3). On LANs
59 with a small RTT this can mean a high processing load and reduced
60 performance, since then the nofeedback timer is triggered very
61 frequently.
62
63 This option enables to set a higher lower bound for the nofeedback
64 value. Values in units of milliseconds can be set here.
65
66 A value of 0 disables this feature by enforcing the value specified
67 in RFC 3448. The following values have been suggested as bounds for
68 experimental use:
69 * 16-20ms to match the typical multimedia inter-frame interval
70 * 100ms as a reasonable compromise [default]
71 * 1000ms corresponds to the lower TCP RTO bound (RFC 2988, 2.4)
72
73 The default of 100ms is a compromise between a large value for
74 efficient DCCP implementations, and a small value to avoid disrupting
75 the network in times of congestion.
76
77 The purpose of the nofeedback timer is to slow DCCP down when there
78 is serious network congestion: experimenting with larger values should
79 therefore not be performed on WANs.
