• The number of lost packets and the total percent of losses at the present time in the transmission of the participant's video streams.
• The server's adaptive jitter buffer value for a particular participant is measured in milliseconds and reflects the state of the data transfer channel from the participant to the server. The higher this indicator, the greater the video delay for this participant.
• Participant connection server. In case cascading is used.

Управление группой участников

Есть возможность управлять настройками группы участников. Если выбрать одного или нескольких участников из списка, появится панель группового управления с кнопками:

• "Включить" - нажатие этой кнопки добавляет выделенных участников (одного или нескольких) в конференцию;
• "Включить микрофон" - кнопка включения микрофона у одного или нескольких участников;
• "Включить камеру" - кнопка включения камеры у одного или нескольких участников;
• "Включить звук" - кнопка включения звука у одного или нескольких участников;
• "Включить видео" - кнопка включения видео у одного или нескольких участников;
• "Показать/Скрыть скриншот" - кнопка вывода скриншота у одного или нескольких участников.

Если активировать переключатель "Обратные действия", то все перечисленные кнопки приобретут обратный функционал, при этом действие будет производиться с выбранными участниками.

В данном списке отображение статусов участников производится следующим образом:

• в виде плиток, при наведении курсора на подключенного участника;

Изображение закрытого замка показывает, что происходит шифрование RTP-трафика.

• в виде строк статусы отображаются постоянно, в этом виде доступен вывод дополнительных параметров подключения, таких как потери, количество передаваемых кадров в видеопотоках, актуальные битрейт видеопотоков и т.д. при включении пункта "Доп. информация";

• в виде краткого списка – доступно отображение IP-адреса участника и статус регистрации на сервере.

Статусы подключения участника

Стандартные статусы выводят следующую информацию подключения участника:

• светло-зеленый цвет - участник подключён;
• строка, окрашенная в тёмно-зеленый - это участник, который показывает презентацию;
• текущий лектор – строка выделяется светло-голубым цветом среди подключенных участников;
• жёлтый цвет - означает, что участник смотрит веб-трансляцию, а также запрос слова;
• серая строка - это добавленный в конференцию участник, но не подключенный;
• чёрный цвет означает, что у участника выключен микрофон;

• Время подключения участника;

• Видеоразрешение подключения к серверу участника конференций - стрелка перед значением указывает направление потока, если вместо значения появляется прочерк, то видеопотока нет. Аналогичным образом строятся остальные статусы;
• Используемые видеокодеки подключения участника конференций;
• Используемые аудиокодеки подключения участника конференции;

Расширенные статусы выводят следующую информацию подключения участника:

• Количество кадров в секунду в видеопотоках участника;
• Текущее значение полосы пропускания, занимаемое основным потоком видеоданных;
• Forward error correction - восстановление потерянных пакетов;
• Overhead - дополнительный трафик, который содержит дубликаты пакетов, с помощью которых произойдет восстановление, если какие-либо пакеты будут потеряны.

• Статус приема/отправки потока контента по протоколам H.239, BFCP;
• Количество кадров в секунду в видеопотоке контента по протоколам H.239, BFCP;

• Текущее значение полосы пропускания, занимаемое дополнительным видеопотоком для передачи контента по протоколам H.239 и BFCP;
• Количество потерянных пакетов и общий процент потерь в настоящий момент времени в передаче видеопотоков участника;

• Значение адаптивного джитер-буфера сервера для конкретного участника измеряется в миллисекундах и отражает состояние канала передачи данных от участника к серверу, чем выше этот показатель, тем больше задержка видеоизображения у данного участника;
• Сервер подключения участника, в случае если используется каскадирование.

• Информация о входящем и исходящем аудиоканалах.

Индикация потерь

На индикаторе потерь отображаются входящие и исходящие потери. Для каждого направления показано общее количество потерянных пакетов и мгновенные потери пакетов в процентах.

Определить наличие и величину потерь сетевых пакетов отдельных подключений к сеансу ВКС можно в "Управлении конференцией". Для этого нужно выбрать расширенное отображение участников в конференции и включить переключатель "Доп. информация".

Информацией о потерях стороны подключения (сервер и клиент) обмениваются по протоколу RTCP (https://datatracker.ietf.org/doc/html/rfc3550#section-6 ) отправляя раз в 2-3 секунды друг другу Receiver Report (RR) (https://datatracker.ietf.org/doc/html/rfc3550#section-12.1), который содержит следующие параметры:

Cumulative number of packets lost - общее количество потерянных пакетов, считается с момента подключения участника к серверу.
Fraction lost - доля потерянных пакетов, рассчитанная за время с момента предыдущего отправленного отчета RR.

Скриншот из программы Wireshark c дампом сетевого трафика SIP-подключения и наложенным фильтром для отображения только пакетов протокола RTCP:

Именно эти значения и выводятся на индикаторе потерь по каждому подключению:

На индикаторе отображаются отдельно входящие (1) и исходящие (2) потери.

Пересчет информации производится при получении или отправке каждого RR: входящие потери (in) считает сервер, а исходящие потери (out) считает клиент.
