server is used for secure communication between the LAN and WAN, and can be used to send secure encrypted e-mail between "All users", for "Web server" to provide secure Web access for "remote workstations", and secure access to the intranet in the enterprise.11. Exchange Mail ServerThe Exchange server family is a Microsoft E-mail server that provides e-mail services for all workstations, remote workstations, and Internet users. Exchange server requires Active Directory support when it is in use

the specified capability of the client software to respond to the request and establish a connection. if the user rejects the call, the session will be redirected to the voice mail server or another user. for "specify capabilities", refer to the features you want to enable. for example, the client software can support video conferencing, but the user only wants to use audio conferencing, then only the audi

time, most telecom operators have also considered H.323 as the first choice for building a new generation of video conferencing systems, and transferred the traditional circuit-based H.320 video conferencing applications to IP-based H.323 systems. in terms of application scale, H.323 has become the dominant factor in VOIP and multimedia communication protocols in actual telecom operations. SIP is called th

user.Once a user address is found, the request is sent to the user. Several options are available. In the simplest case, the user's phone client receives the request-that is, the user's phone rings. If the user accepts the call, the customer uses the specified capability of the client software to respond to the request and establish a connection. If the user rejects the call, the session will be redirected to the voice mail server or another user. For "specify capabilities", refer to the featur

The continuous development of the Internet, the rise of a variety of new technologies, today I first listed the most basic development process, suitable for the development of video conferencing system, voice video chat system, distance education platform and instant communication platform ( IM ) and so on. Hope to be helpful to those who like this. At the same time welcome the major experts to participate in the discussion, mutual exchange, learning.

DShow technology to capture device information and video data from enumerated videos, which means that most video capture devices can be supported, and for video capture cards (such as Hoi Hong HD cards) that require a separate driver. Video capture supports a variety of media types, such as I420, YUY2, RGB, Uyuy, etc., and can be frame size and frame rate control.Video Codec---video_codingThe source code is in the Webrtc\modules\video_coding directory. WEBRTC uses I420/VP8 codec technology. VP

eavesdropping is to enable the switch to have a layer-3 awareness, and intercept IGMP messages sent between the host and the router to determine the location of the group members. CGMP enables the vswitch to understand group member distribution through Protocol interaction between the vro and the vswitch, but CGMP is a Cisco proprietary protocol. Multicast high-level protocol IP multicast cannot ensure reliable data transmission, and may cause packet loss, disorder, and duplication. Different p

With the rapid development of the global Internet), the number of Internet users is growing exponentially. The ratio of Internet-dominated Data Communication in the total amount of communication services is increasing rapidly, internet services have become the most rapidly developing and competitive multimedia communication industry. The dramatic increase in Internet transmission and processing capabilities has led to an increasing number of online applications, especially the development and ma

And Lync is a very good internal communication and conferencing system, features rich, including instant messaging, application sharing, audio, video, PPT, whiteboard, voting, appointment and schedule, recording, notes and other functions. More importantly, the cost savings can be greatly reduced compared to traditional conference calls and Sametime,lync. SharePoint can help Lenovo employees develop intelligent portal s

), constructor injection, attribute injection, method injection. The next three ways are collectively referred to as "dependency injection", and the first way I have sporogenous a noun, called "dependent endogenous", is that the fundamental difference is whether the creation of the object I depend on is done by myself. Of course, this is the concept of a generalized dependency injection, which we would not normally use. What we usually use is the narrow concept of dependency injection. However,

field, more convenient and fast.The most pressing telemedicine solution is to integrate patients ' real-time medical information into their existing medical records, thus increasing the transparency between doctors and patients. But also can rely on the video conference system to the critically ill patient to carry on the timely consultation treatment, saves in the distress. Reduce the trouble of the patient's repeated referral.To sum up, the remote video perfect medical system is visible and f

number is also used to determine the correct location of a packet, for example, without sequentially decoding the packet when the video is decoded. But RTP's original design was designed to meet the needs of multi-participant multimedia conferencing, which was not limited to specialized applications. Storage of continuous data, interactive distributed simulations, dynamic tagging, and control and measurement applications may also be suitable for use

This article from: http://www.cnblogs.com/yuanfan/archive/2010/12/17/1909379.html What is punching and why? Due to the rapid development of the Internet, IPv4 addresses are insufficient, so each host cannot be assigned a public IP address, so Nat address translation is used. Below is a picture I found online Generally, a connection is actively initiated by a host in the private network (such as the "Computer A-01"), the packet is converted to the server on the public network (su

The background has been followed up with the UI.The next step might be to make the UI even faster, ensuring that a UI has been designed in the background when the previous UI design

We used to do the Lync reverse proxy we used to use TMG, but TMG has too many problems, such as only installed on the Server2008 server, and Microsoft has no subsequent development, we can now use IIS arr to implement the reverse proxy function, he compared to TMG does not need to deploy the server alone, Just find a server with Server2012 installed and you can use it to install the IIS Arr component.So since both TMG and IIS arr can implement the reverse proxy for Lync, what's going on somewher

On Windows, WebRTC uses dshow technology to collect device information and video data of video enumeration. This means that most video collection devices are supported.ProgramVideo Acquisition Card (such as haikang HD card) is powerless. Video collection supports multiple media types, such as i420, yuy2, RGB, and uyuy, and supports frame size and frame rate control. Video Codec ---

Abstract: currently, online video chat software, video conferencing software, and visual IP Phone software can be seen everywhere. Do you want to do it yourself? In fact, this type of software is built with video and network. If you are familiar with video capture and network transmission technology, it's hard for you. Microsoft provides software developers with a vfw sdk (Video for Windows SDK) dedicated for Video capturing. It is very easy to use it
