Switches are constantly evolving along the speed, multi-layer switching, and intelligent exchange directions. A new trend is that intelligent exchange at the edge access layer drives the development of intelligent exchange from the core of the network to the edge. In the past, the network architecture only adopted layer-3 routes of smart switches and layer-4 to layer-7 Smart switches at the core. On the edge, the network architecture adopted common layer-2 access switch products without any netw

priority for your VoIP service. Speaking of WMM, it is actually a subset of the IEEE 802.11e standard, which defines the quality of service QoS for Wi-Fi ). Without QoS, all applications running on different devices have the same opportunity to transmit data frames. This method works well for data traffic from web browsers, file transfers, e-mails, and other applications, but it does not work for multimedia applications.

In terms of restructuring the data center, how can we build a UC platform. What aspects should we know about the Unified Communication solution in this regard? Now let's discuss and summarize this question. Hope to help you. Reorganizing a data center Today's enterprise communication industry is a popular trend, that is, the Unified Communication, VoIP system and other communication applications as a software service together with other enterprise app

includes data loss and fraud issues. In view of this, what security factors should the IT supervisor consider when deploying a Unified Communication System? First, SIP relay. The SIP relay "creates" another channel for external attacks to the enterprise's telephone system. In most VoIP architectures, the PSTN serves as a fireproof channel between the enterprise telephone system and the outside world. Logically, the more isolated the

Priority) to your voice and multimedia applications. In this case, you can select a specific application from the drop-down menu, and then select a higher priority level, medium, normal, or low), and then click the Add button. For example, you can set a lower priority for BitTorrent and other download services, and a higher priority for your VoIP service. Speaking of WMM, it is actually a subset of the IEEE 802.11e standard, which defines the quality

Access Switch unknown multicast discard Technical Features Business Separation User Services are mainly HSI (Internet Services), IPTV services, and VOIP services. Each Service has different network requirements. To facilitate the deployment of QOS and security policies, therefore, we must differentiate the business. The simplest way is to mark different services through different VLANs. Considering the business characteristics, Internet services usua

New things are always curious and worrying. Just like UC, its technology and market are not yet mature. Many enterprises are also holding a wait-and-see attitude. Therefore, the rise of mobile communication and wireless networks over the years has brought people to notice the Unified Communication UC technology. UC is a new product. This term covers speech, video, legacy applications in enterprise data networks, and network-centric applications. It can be said that UC is a reasonable development

Session management An abstract session layer that provides the ability to create and manage sessions. This layer protocol is left to the application developer to customize the implementation.

Asterisk is a fully-software PBX system. It can run on Linux, BSD, Windows (simulated), and OS X. It provides all the features you want from the PBX, and is more than the PBX. Asterisk supports four types of VoIP protocols. By using relatively inexpensive hardware, it can interconnect with almost all standard-based telephone devices. Asterisk provides a directory-based voice mailbox Service (VOICEMAIL), teleconference, Interactive Voice Response (IVR

communication no longer the only choice. Their appearance immediately attracted a large number of users, but the traditional telecom market was not greatly affected. It seems that their business is not in conflict. Until the emergence of VoIP. In fact, the VoIP technology began to appear in 1990s. However, due to bandwidth restrictions and immature technology, the quality of calls cannot be guaranteed,

Actually, speex for voice dialogs, it is equivalent to Vorbis [ A coding software that compresses sound sources, open source and copyright-free

-Business Integrated Access Platform IAN-8000 helps telecom users expand new VOIP and broadband applications to the widest possible service area. In the central bureau, iAN-8000 can help users provide a variety of services through the unified platform, including TDM voice, VoIP, asymmetric DSL 2 (ADSL 2) and ADSL 2 +. This is important for providing the three-in-one voice, data, and video functions. This pl

mechanism is not adopted, cloud backup applications will consume as much enterprise bandwidth as possible. If you're just backing up small files, such as Microsoft Office documents, you don't have to worry too much about the bandwidth that your backup application is consuming. However, if it is the initial cloud environment backup enterprise data, you should consider the bandwidth consumption problem. I have seen some enterprises one months before the completion of the initial data backup, if t

In this increasingly networked world, people are constantly using communication between people and devices in new and different ways. Some types of communication are already familiar, such as IP voice (VoIP), digital images, multicast, video-on-demand, peer-to-peer file sharing, remote video conferencing, and more. However, all of these applications have a common feature: the need for network bandwidth can be described as "insatiable". In the long ru

sigtran. This project started in 1996 and implemented the No. 7 signaling system recommended in the ituq.700 series. With the rise of VoIP and SoftSwitch, openss7 focuses on the implementation of sigtran protocol (sigtran can be considered as the NGN version of SS7 ). In fact, openss7 is not limited to the 7th signaling, but a series of ISDN and SoftSwitch signaling are all under consideration. For technical details about openss7, refer to the open-
