Привет!
Не так давно мы уже затрагивали тему IoT или «Интернета Вещей» в рамках прошедшей конференции WinHEC (Hardware Engineering Conference) 2015.
Одна из главных проблем, волнующих многих, это вопрос обеспечения связности и обнаружения устройств, говорящих на разных языках, протоколах и др. Эту проблему призван решить фреймворк AllJoyn, в совокупности с протоколом Thread, к рабочей группе над которым Microsoft присоединился 1 июля. Об AllJoyn и пойдёт наша речь.
Отдельно мы решили рассмотреть одну из очень важных частей этой концепции в разрезе Windows 10 (но, конечно, не ограничивающейся этой ОС) — популярный протокол взаимодействия устройств AllJoyn, который уже стал де-факто стандартом. Тем более, что Windows 10 и сопутствующий Windows 10 SDK предоставляют специальную поддержку данного протокола.
Что за AllJoyn?
AllJoyn — это фреймворк (и протокол) с открытым исходным кодом, предназначенный для взаимодействия приложений, устройств и пользователей через WiFi и Bluetooth (и другие типы сетей) вне зависимости от типа устройства.
Основной заслугой данного протокола является специальный уровень абстракции, позволяющий устройствам и приложениям предлагать себя в качестве провайдера определенных услуг и находить другие устройсва и приложения без использования какого-либо дополнительного оборудования и специальных серверов.
Архитектурно это выглядит следующим образом – AllJoyn-сеть состоит из виртуальных роутеров (Routers) и приложений (Apps). Приложения общаются со своим роутером, а роутеры, в свою очередь, с другими роутерами и другими приложениям, относящимися к данному роутеру. Таким образом, приложения могут общаться друг с другом посредством сети этих виртуальных роутеров. При этом приложение и вирутальный роутер, к которому он прикреплен, могут находится на разных физических устройствах.
Подробнее про архитектуру AllJoyn можно почитать тут (общая информация) и тут (Windows 10 IoT).
Windows 10 IoT AllJoyn
Спешу порадовать — в Windows 10 включена полная поддержка данного протокола, а именно:
Во-первых, вам не нужно заботиться об AllJoyn-роутере, описанном выше, так как Windows 10 включает специальный сервис AllJoyn Router Service, который может использоваться как вашими приложениями, так и другими устройствами в сети.
Во-вторых, Windows 10 включает специальный API для работы с AllJoyn-протоколом, который находится в пространстве имен Windows.Devices.AllJoyn (https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.alljoyn.aspx) (поддерживаются С++, C#, JavaScript). Таким образом, вам не нужно ставить дополнительные SDK и инструменты, все уже готово и работает.
И, конечно же, дополнительные инструменты для разработчиков:
- AllJoynCodeGen — часть Windows 10 SDK (лежит в C:\Program Files (x86)\Windows Kits\10\bin\x64\), позволяет сгенерировать полностью готовую Windows Runtime библиотеку для работы с AllJoyn-сервисом, используя описание сервиса в формате xml (AllJoyn Introspection XML). Посмотреть и послушать подробнее.
- getajxml — специальная утилита, которая позволяет обнаружить все AllJoyn-устройства в сети, получить детальную информацию, в том числе сгенерировать AllJoyn Introspection XML, который можно использовать для автогенерации кода. Подробнее можно посмотреть на видео выше.
- AllJoyn Explorer — похожая утилита, выполненная в виде Windows приложения и позволяющая не только увидеть интерфейс, но и динамически вызвать методы. Скачать можно здесь.
Пример создания AllJoyn-приложения на Windows 10
Ниже мы будем использовать Windows 10 Insider Preview и бесплатную версию Visual Studio 2015 Community Edition (RC) (скачать).
Одним из популярных примеров AllJoyn является проект Connected Lighting Project, который представляет ни что иное, как лампочку, реализующую AllJoyn-интерфейс для получения информации и управления устройством.
Ниже посмотрим на процесс создания Windows 10-клиета для управления такой умной лампочкой.
Полный исходный код приложения можно найти на GitHub. Итак…
Шаг 1. Создаем новый Widows Runtime C++ компонент и используем AllJoynCodeGen (см. выше) для автогенерации кода.
Публичный AllJoyn Introspection XML для данного проекта можно найти тут.
Детальные инструкции лежат здесь.
Шаг 2. Создаем новое Windows 10 C#/XAML приложение и добавляем в зависимости только что созданный Windows Runtime компонент.
Шаг 3. Теперь мы можем реализовать логику по нахождению и управлению нашей лампочкой
Для того, чтобы найти и подсоединиться к лампочке:
Чтобы изменить яркость:
Это действительно весь код 
Основные AllJoyn классы были предоставлены Windows 10 API, остальные сгенерированы c помощью AllJoynCodeGen.
Шаг 4. Тестируем:
В качестве тестовой лампочки можно использовать Lamp Simulator Application (Android, скачать). Итак, запускаем наше приложение на Windows Phone 10 телефоне и Lamp Simulator на Android, и смотрим, как это все работает вместе.

Services and processes are an essential part of any operating system. Sometimes you may come across services that have bizarre names. One such service is ‘AllJoyn Router‘ on Windows 10. If you have seen it recently, and want to know what it is, and if it is safe, then this post is specifically written for you.
Here, I will explain what is AllJoyn Router Service on Windows 10. We will also take a look if it is safe and essential, or if we can disable it. If we can, then how. All your queries about it will be answered here.
What is AllJoyn Router Service on Windows 10?
Windows is especially known to deliver the best user experience. It achieves this with the help of countless services, processes, and programs that keep running in the background and foreground to provide splendid performance. Some of the Windows services are easily understandable, while some of them are rather hard to understand. One somewhat hard to understand Windows service is AllJoyn Router.
By the name of this service, one would think it is involved with the network or router configuration part of the computer. However, that isn’t true. Instead, it is an open-source service that works as a communication bridge between Windows 10 devices and IoT (Internet of Things). All Windows 10 computers and laptops have it built-in now.
What does it do?
The AllJoyn Router Service on Windows 10 isn’t much popular. The majority of Windows 10 users don’t know about it and feel confused when they come across it. Basically, it is a project from the AllSeen Alliance that is developed to enable the ‘Internet of Things.’ This service allows your computer to talk to other AllJoyn-enabled devices for home automation and many other futuristic activities.
When you boot your Windows 10 computer, this service starts running and stays up most of the time. When it is running, it helps your PC to communicate with the other devices that also have the same service enabled. If you understand what IoT is, then you’d figure out that Microsoft has embedded it for their next-gen approach.
Is AllJoyn Router Service Safe?
Since this pretty uncommon service by AllJoyn is not much known to the Windows users, they often end up wondering if it is safe or malicious. If you are also thinking the same, then I should tell you that it is absolutely safe. There is nothing to worry about it.
Microsoft has released a statement that it is for the purpose of the advancement of IoT within the Windows 10 OS. If you notice it, you should just let it run as it will do no harm to you.
Is it a virus?
No, the AllJoyn Router Service is not a virus. It is merely a service by AllSeen Alliance that works as a communicator between Windows 10 and other devices for IoT-based activities. If you want to double-check it, then you can scan it Windows Defender or with any reliable antivirus, you will find that none of them will mark it as a threat.
It is completely safe and useful. You should let it run it as it will never harm your device. However, you should always keep your Windows Defender or any other antivirus tool active, so when any threat with a similar name tries to invade the system, it doesn’t go unnoticed.
Is this service essential?
The AllJoyn Router Service is not an essential Windows service, but it is a pretty important one. This service allows other Windows services on your computer to exchange information through the Internet of Things. If it isn’t running, your PC will lose the ability to connect with other IoT-enabled devices. That’s why it is an important service.
However, a normal Windows 10 users would rarely need it. That’s why it is not essential. If you are finding it consuming a lot of PC resources, then you can think of disabling it to free up resources. I have explained that part below.
Should You Disable AllJoyn Router Service?
Since this IoT-related service isn’t harming your PC and just serving its purpose, I’d recommend that you let it run. However, if you are thinking of disabling it, you must know if you need it or not. A casual Windows user who performs basic tasks or plays games would rarely need it. This service is oriented specifically for the industry-enthusiasts.
So, you can disable it if you want. But, I’d recommend that you should let it run just for the convenience aspect. If you’ll disable it, your PC will not be able to exchange information by IoT. The description of the service also states that if the service is stopped, the AllJoyn clients that do not have their own bundled routers will be unable to run. So, I’d suggest that you don’t disable it.
How to Disable it?
If you have decided that you want to disable this particular service, then I will guide you with that. Remember that disabling the service will have both a positive as well as a negative impact on your PC. The positive will be that your computer’s resources would be freed, so it may run comparatively better. And, the negative would be that your PC will not be able to communicate with other IoT-enabled devices.
Once you are ready, follow these steps to disable the AllJoyn Router service on your computer:
Step-1: Press the Windows + R key to trigger the Run dialog box. Type services.msc in it and hit Enter to access the Services window.
Step-2: In the Services window, find and choose ‘AllJoyn Router Service‘ from the list of tasks, right-click on it, and choose ‘Properties.’
Step-3: If you see the service running, click on ‘Stop’ to stop the service, and then select ‘Disabled’ under the ‘startup type’ box.
Step-4: After that, click on Apply, and then click on OK to save the changes.
That’s it. Now the service is disabled and it won’t run again until you manually turn it on. You can do that in a similar fashion.
Final Verdict
AllJoyn Router is an unidentified Windows 10 service that Windows users often worry about it. However, there is nothing malicious or unsafe about it. This service only works as a communicator between your device and other IoT-enabled devices for futuristic activities. You should let it keep running as it won’t harm your computer. But, if you want to disable it, then you can do that by following the procedure I have mentioned.
That’s all for this post. I hope you find it helpful. Feel free to use the comment box to share your opinions about it, or to ask about any other Windows service.
