: 　 VoIP gateways are mainly used for IP telephone communication between enterprise branches. They can provide traditional voice interfaces and connect to existing enterprise telephone switches (PBX) or group telephones, and bypass the long-distance phone to the IP network Internet/Intranet ). The main feature of VoIP Gateway applications is to make full use of existing network resources, save users' long-distance calls, and combine with the existi

, if the voice service is enabled on the IP network, additional phone service control devices must be added. It is worth mentioning that IP packets transmitted in the IP network can carry any user data information, it creates conditions for transmission of voice, data, multimedia streams, and other information in a bearer network, both the telephone network and the data network have some inherent defects and cannot be transformed into a "full-service network" through simple transformation. There

It is impossible for a dual-nic computer to have two gateways, because the default gateway can only be one. Install two NICs for the server, with different ip addresses and gateways (intranet and Internet) respectively. The Internet can be accessed through the Internet Nic, and the Intranet can be accessed through the Intranet Nic, it seems very easy to implement, but there are some problems, because the De

network architecture will be better able to ensure security without restricting business development, as applications and APIs can be built to the new business requirements, with the latest architecture, quickly responding to business needs and gaining market opportunity. in fact, this stratification can also be seen as "north-South" traffic and "things" traffic. The core network (north-south) is responsible for transporting traffic to and from the data center. This is where the most front-line

this LAN do not need to set (IP, subnet mask, default gateway) Automatic provisioning is the use of a DHCP server to automatically assign IP addresses, subnet masks, and default gateways to computers in your network. The advantage of this is that once the default gateway for the network changes , all computers in the network get the IP address of the new default gateway as long as the settings for the default gateway in the DHCP server are changed

First we discuss how to use Alipay for payment in laravel applications, there are a lot of related packages on GitHub, here we introduce the two most popular packages: Omnipay for Laravel 5 Lumen and Laravel AliPay. 1. Use Omnipay for Laravel 5 Lumen Introduction Introduction Before we begin, let's take a look at the GitHub project under Omnipay. Omnipay is a framework-independent PHP library that provides support for multiple gateway payment processing. Its introduction website is Http:/

ObjectiveImmediately above, this is the third article, mainly on the MQTT-SN 1.2 protocol for the overall function of the description.Well, this part can be compared with the MQTT protocol.Broadcast and discovery of gatewaysThe gateway can broadcast advertise messages to all clients periodically in the wireless personal area network Wpns only after a successful connection to the MQTT server, allowing the client to passively know the presence of the gateway.Under the same network, multiple

exchange of routing information between vrouters in the autonomous system to maintain mutual connectivity. Each autonomous system has a 16-bit "Autonomous System (AS) number" AS a symbol. Like an IP address, it is allocated by a specialized agency. 　　 Vrouters in autonomous systems are called "Internal gateways" and the protocols used are called "Internal gateways ". There are two types of internal gateway

address. The source IP address in the Vxlan message is the Vtep address of this node, the destination IP address in the Vxlan message is the Vtep address of the peer node, and the Vtep address corresponds to a vxlan tunnel.VNI (VXLAN networks Identifier): VXLAN network identity VNI similar VLAN ID, used to differentiate VXLAN segments, virtual machines of different VXLAN segments cannot communicate with each other directly at Layer two. A vni represents a tenant, even if multiple end users belo

Use nowsms to build your own MMS Center About nowsms================================ Now SMS/MMS Gateway (nowsms) is a set of content delivery solutions for SMS and MMS. Nowsms is a shortcut for deploying and developing SMS, MMS, and wap push solutions. It can be used for SMS gateways, MMS gateways, wap push gateways, and multimedia message centers in Windows 200

in autonomous systems are called "Internal gateways" and the protocols used are called "Internal gateways ". There are two types of internal gateway protocols: distance vector protocol (RIP) and network protocol (OSPF. The difference between the link status routing protocol and the distance vector protocol is that the router that uses the link status routing protocol maintains a network topology instead of

Freesco implements Linux Routing SystemThe Internet is made up of network interconnection, and the device implementing Internet interconnection is the gateway. Any user connects to the Internet through a gateway. Most gateways on the Internet are dedicated routers and switches. At present, Linux is becoming more and more universal. After proper configuration, it can take the role of a router, the physical cornerstone of the Internet. After a high leve

Exclusive gateway graphics The exclusive gateway is displayed as a common gateway (for example, a diamond figure), which is represented by an "X" iconExclusive or (XOR)Semantics. Note: The exclusive gateway is used by default for gateways without internal icons. The BPMN 2.0 specification does not allow simultaneous use of diamond images without X and X in the same process definition.Process file: Exclusive gatew

Today I saw the network protocol (5) Web server.In the second chapter, we understand how a simple client interacts with the server. Now let's see what improvements are being made in practice.1 Keyword: mapping. This mapping allows the client and server to be separated. A client corresponding to a DNS mapping, and then through the map to send his request to the server, it feels like an ancient matchmaker, she must be in deep harmonic two habits of thinking. Translate this word "map" to the other

a library using WSGI rather than a large framework. This also allows application developers to select the most appropriate components for their applications, rather than using a single framework that has both advantages and disadvantages. Finally, the point to be mentioned is that this PEP333 does not involve deployment. After a large number of servers and frameworks are implemented WSGI, there may be new pep to describe how to deploy the WSGI server and the application framework. Specifica
