In the case of RTC, manifests are sent after the data they contain and on the
consumer side, data packets are immediately forwarded to the application, *even
if they weren't authenticated yet via a manifest*. This is to minimize latency.
The digest of incoming data packets are kept in a buffer while waiting for
-manifests to arrive. When that buffer goes above a threshold `T`, an alert is
-raised by the verifier object. That threshold is computed as follows:
+manifests to arrive. When the buffer size goes above a threshold `T`, an alert
+is raised by the verifier object. That alert threshold is computed as follows:
```
-T(t) = producer_rate(t) * max_unverified_time
+T = manifest_factor_alert * C_max
```
-`max_unverified_time` is a consumer socket option, in milliseconds. It is set
-to `2000` by default. To change it:
+The value of `C_max` is passed by the producer to the consumer at the start of
+the connection. `manifest_factor_alert` is a consumer socket option. It
+basically acts on the resilience of manifests against networks losses and
+reflects the application's tolerance to unverified packets: a higher value gives
+the transport the time needed to recover from several manifest losses but
+potentially allows a larger number of unverified packet to go the application
+before alerts are triggered. It is set to `20` by default and should always be
+`>= 1`. To change it:
```cpp
-consumer_socket_->setSocketOption(GeneralTransportOptions::MAX_UNVERIFIED_TIME, 4000);
+consumer_socket_->setSocketOption(GeneralTransportOptions::MANIFEST_FACTOR_ALERT, 10u);
+```
+
+The buffer does not keep unverified packets indefinitely. After a certain amount
+of packets have been received and processed (and were verified or not), older
+packets still unverified are flushed out. This is to prevent the buffer to grow
+uncontrollably and to raise alerts for packets that are not relevant to the
+application anymore. That threshold of relevance is computed as follows:
+```
+T = manifest_factor_relevant * C_max
+```
+
+`manifest_factor_relevant` is a consumer socket option. It is set to `100` by
+default. Its value must be set so that `manifest_factor_relevant >
+manifest_factor_alert >= 1`. If `manifest_factor_relevant <=
+manifest_factor_alert`, no alert will ever be raised. To change it:
+```cpp
+consumer_socket_->setSocketOption(GeneralTransportOptions::MANIFEST_FACTOR_RELEVANT, 200u);

- 2013-05-02 (0.2.8):
-
- * Use quadratic probing. When the capacity is power of 2, stepping
- function i*(i+1)/2 guarantees to traverse each bucket. It is better than
- double hashing on cache performance and is more robust than linear probing.
-
- In theory, double hashing should be more robust than quadratic
- probing. However, my implementation is probably not for large hash tables,
- because the second hash function is closely tied to the first hash function,
- which reduce the effectiveness of double hashing.
-
- Reference: http://research.cs.vt.edu/AVresearch/hashing/quadratic.php
-
- 2011-12-29 (0.2.7):
-
- * Minor code clean up; no actual effect.
-
- 2011-09-16 (0.2.6):
-
- * The capacity is a power of 2. This seems to dramatically improve the
- speed for simple keys. Thank Zilong Tan for the suggestion. Reference:
-
- - http://code.google.com/p/ulib/
- - http://nothings.org/computer/judy/
-
- * Allow to optionally use linear probing which usually has better
- performance for random input. Double hashing is still the default as
- it is more robust to certain non-random input.
-
- * Added Wang's integer hash function (not used by default). This hash
- function is more robust to certain non-random input.
-
- 2011-02-14 (0.2.5):
-
- * Allow to declare global functions.
-
- 2009-09-26 (0.2.4):
-
- * Improve portability
-
- 2008-09-19 (0.2.3):
-
- * Corrected the example
- * Improved interfaces
-
- 2008-09-11 (0.2.2):
-
- * Improved speed a little in kh_put()
-
- 2008-09-10 (0.2.1):
-
- * Added kh_clear()
- * Fixed a compiling error
-
- 2008-09-02 (0.2.0):
-
- * Changed to token concatenation which increases flexibility.
-
- 2008-08-31 (0.1.2):
-
- * Fixed a bug in kh_get(), which has not been tested previously.
-
- 2008-08-31 (0.1.1):
-
- * Added destructor

+ * Use quadratic probing. When the capacity is power of 2, stepping
+ function i*(i+1)/2 guarantees to traverse each bucket. It is better than
+ double hashing on cache performance and is more robust than linear probing.
+
+ In theory, double hashing should be more robust than quadratic
+ probing. However, my implementation is probably not for large hash tables,
+ because the second hash function is closely tied to the first hash function,
+ which reduce the effectiveness of double hashing.
+
+ Reference: http://research.cs.vt.edu/AVresearch/hashing/quadratic.php
+
+ 2011-12-29 (0.2.7):
+
+ * Minor code clean up; no actual effect.
+
+ 2011-09-16 (0.2.6):
+
+ * The capacity is a power of 2. This seems to dramatically improve the
+ speed for simple keys. Thank Zilong Tan for the suggestion.
+ Reference:
+
+ - http://code.google.com/p/ulib/
+ - http://nothings.org/computer/judy/
+
+ * Allow to optionally use linear probing which usually has better
+ performance for random input. Double hashing is still the default as
+ it is more robust to certain non-random input.
+
+ * Added Wang's integer hash function (not used by default). This hash
+ function is more robust to certain non-random input.
+
+ 2011-02-14 (0.2.5):

+ * Allow to declare global functions.

+ 2009-09-26 (0.2.4):

+ * Improve portability
+
+ 2008-09-19 (0.2.3):
+
+ * Corrected the example

+
+ 2008-09-11 (0.2.2):

- * DESCRIPTION
- * escape_string quotes and escapes a string to be usable with collectd's
- * plain text protocol. "simple" strings are left as they are, for example if
- * buffer is 'simple' before the call, it will remain 'simple'. However, if
- * buffer contains 'more "complex"' before the call, the returned buffer will
- * contain '"more \"complex\""'.
- *
- * If the buffer is too small to contain the escaped string, the string will
- * be truncated. However, leading and trailing double quotes, as well as an
- * ending null byte are guaranteed.
- *

- * NULL);
- *
- * DESCRIPTION
- * Takes a list of type instances and values and dispatches that in a batch,
- * making sure that all values have the same time stamp. If "store_percentage"
- * is set to true, the "type" is set to "percent" and a percentage is
- * calculated and dispatched, rather than the absolute values. Values that are
- * NaN are dispatched as NaN and will not influence the total.
- *
- * The variadic arguments is a list of type_instance / type pairs, that are
- * interpreted as type "char const *" and type, encoded by their corresponding
- * "store_type":
- *
- * - "gauge_t" when "DS_TYPE_GAUGE"
- * - "absolute_t" when "DS_TYPE_ABSOLUTE"
- * - "derive_t" when "DS_TYPE_DERIVE"
- * - "counter_t" when "DS_TYPE_COUNTER"
- *
- * The last argument must be
- * a NULL pointer to signal end-of-list.
