41 * Bandwidth (in/out) to assume initially (before either peer has
42 * communicated any particular preference). Should be rather low; set
43 * so that at least one maximum-size message can be send roughly once

49 * After how long do we consider a connection to a peer dead
50 * if we don't receive messages from the peer?

55 * How long do we delay reading more from a peer after a quota violation?
57 #define GNUNET_CONSTANTS_QUOTA_VIOLATION_TIMEOUT GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_SECONDS, 2)
60 * How long do we wait after a FORK+EXEC before testing for the
61 * resulting process to be up (port open, waitpid, etc.)?
63 #define GNUNET_CONSTANTS_EXEC_WAIT GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_MILLISECONDS, 100)
66 * After how long do we consider a service irresponsive
67 * even if we assume that the service commonly does not
68 * respond instantly (DNS, Database, etc.).
70 #define GNUNET_CONSTANTS_SERVICE_TIMEOUT GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_MINUTES, 10)
73 * How long do we delay messages to get larger packet sizes (CORKing)?

78 * Until which load do we consider the peer overly idle
79 * (which means that we would like to use more resources).<p>
81 * Note that we use 70 to leave some room for applications
82 * to consume resources "idly" (i.e. up to 85%) and then
83 * still have some room for "paid for" resource consumption.
