Lower Your Network Implementation Costs With Gateways

A gateway is a network point that acts as an entrance to another network. On the Internet, a node or stopping point can be either a gateway node or a host (end-point) node. Both the computers of Internet users and the computers that serve pages to users are host nodes. The computers that control traffic within your company's network or at your local Internet service provider (ISP) are gateway nodes.

 A network gateway is an inter networking system capable of joining together two networks that use different base protocols. A network gateway can be implemented completely in software, completely in hardware, or as a combination of both. Depending on the types of protocols they support, network gateways can operate at any level of the OSI model.

Because a network gateway, by definition, appears at the edge of a network, related capabilities like firewalls tend to be integrated with it. On home networks, a broadband router typically serves as the network gateway although ordinary computers can also be configured to perform equivalent functions.

How Gateways Works

A gateway is a network point that works as an access to another network. Generally in intranet a node can be either a gateway node or the nodes that join the network are gateways. In large organization where the computers control the traffic between organization networks are gateway nodes. Like that the computers used by ISP to connect different user with each other at a time to the internet are gateway nodes. In a project of any business company computer server work as a gateway nodes and it may be proxy server or firewall some time. A gateway may connected to a router because a router exactly known where to through a given packet of data that appears at the gateway then a switch finalize the actual in and out path of the gateway for the specified packet .A gateway is a compulsory features of routes even though other devices can perform as a gateway. The operating system mostly used this term and internet connection sharing act as a gateway and creating a connection among internal network.

Gateway Devices

A gateway is full of various types of devices which are essential to make available system interoperability as signal translators. The other devices are protocol translators, impedance matching devices, rate converters, and fault isolators. Some time gateway attached with both router and switch to perform action. When a user using home network with gateway has a transceiver used to set up a wireless connection..

Gateway Usage, Uses of Gateways

There are many kind of usage of gateway in a network as listed below.

·     A gateway can be implemented in software, hardware and some time as a mixture of together. There are lots of equipments and techniques which are being processed such as voice and data communication.

·    The gateways are the best option to achieve the multimedia communications between dissimilar networks because every network has different protocol and characteristics.

·    Gateways are also a key mechanism of any telephony communications. Gateway is offering bridge between telephone network and internet.

·    For real time communication gateway supporting audio conversion and carry out extinction and call setup. Gateway also controls the processing information across the network which contains information about to set up the actual end to end call.

·    A gateway may also install on a standalone device. A gateway performs as the interface between local and wide area protocols such as TCP/IP on the Internet.

·   Gateway is also offering on-line services exclusive of having a preceding service agreement or a continuing association with the service supplier.

STOP USING ANALOG PHONES SWITCH TO IP PHONES

What is IP Phone?

    IP Phones are sometimes called VoIP telephones, SIP phones or soft phones. These are just different names for a device/software client that is designed to support the transmission of voice over the internet, or what is better known as VoIP (or Voice over Internet Protocol) technology.

Difference between Analog and IP Phone.

                    

                         Analog phones are the same kind of phones that you've been using for years. The phones in your house are quite likely, analog phones. That means they're extremely reliable, familiar and very easy to use. You just plug them in, and they do what they've always done. IP phones are a little more complicated, since they're little more like computers. Since IP phones plug into the LAN the same way your computer does, you don't need to run phone wires to each workstation at all.

Why IP Phone?        

                          The challenge with standard telephone lines is that you are tethered to the location of the phone number. VoIP is tied to an IP phone, allowing you to make calls from any location where there is an available internet connection. You can take your number and telephone service with you as you travel anywhere in the world.

VoIP apps are available in the app stores of most Internet-ready devices. You don't have to be equipped with a smart phone in order to use the device as a phone

It's well known that VoIP international rates are some of the cheapest you can find. One of the biggest advantages of using VoIP to make international calls is that you can use a phone number from another country that helps you establish a local presence without having to staff an office abroad.

How do IP Phone Works?

                          The “IP” in IP phone system refers to Voice over IP, or having your phone calls routed over the internet or your local network (LAN). This is great for many reasons. First of all, you don’t have to use the telephone network of your telephony service provider for making calls, which will reduce your costs for phone calls. At the same time you are gaining many technical advantages by using IP technology for your telephony.

Users of an VoIP phone system simply plug their IP phone into the nearest LAN port. Then, the IP phone registers automatically at the VoIP phone system. The IP phone always keeps its number, and behaves exactly the same way, no matter where you plug it in – on your desk, in the office next door or on a tropical island.

Default gateways serve an important role in TCP/IP networking. They provide a default route for TCP/IP hosts to use when communicating with other hosts on remote networks.

Gateways, also called protocol converters, can operate at any network layer. The activities of a gateway are more complex than that of the router or switch as it communicates using more than one protocol.

The following illustration shows the role played by two default gateways (IP routers) for two networks: Network 1 and Network 2.

In order for Host A on Network 1 to communicate with Host B on Network 2, Host A first checks its routing table to see if a specific route to Host B exists. If there is no specific route to Host B, Host A forwards its TCP/IP traffic for Host B to its own default gateway, IP Router 1.

The same principle applies if Host B is sending to Host A. Without a specific route to Host A, Host B forwards any TCP/IP traffic destined for Host A to its own default gateway, IP Router 2.

IP-Surveillance GXP 3610_HD

In today’s environment close observation of a person or group, especially one under suspicion is utmost important. Video surveillance is a vital tool for protecting people and property around the clock. The increasing availability and, thus, lower cost of higher-quality cameras makes improving the effectiveness of video more affordable.

 For a long time video surveillance was something mainly used by the government and large, wealthy companies; something you only saw in movies. Now you can see video cameras everywhere you look, whether you’re grabbing a quick bite at a fast-food restaurant, stopped at the intersection (hopefully not as you coast through a red light!), or walking up to your neighbors’ front porch. Video surveillance has become a necessity for small business owners, and is becoming more prevalent for home owners as well.

My reason for writing, however, is not to discuss the reasons for the rise of video surveillance system, but to examine three benefits of having a video surveillance system.

1) Acts as a deterrent to crime
The first benefit to having a video surveillance system is that it acts as a deterrent to crime. Seeing a camera, or a signage warning of cameras, can be unnerving to a would-be criminal.

2) Apprehend a suspect when a crime occurs
Another benefit of having a video surveillance system is the ability to apprehend a suspect when a crime occurs

3) Improve productivity of employees
Another major benefit of having a video surveillance system is improved productivity in the workplace (and at home). Many business owners’ primary motivation for installing a video surveillance system is not the threat from without, but the threat from within. About employees who routinely “steal” an employer’s time, by not doing what they are paid to do when they are paid to do it? At home security cameras can help you see if your children are home when they are supposed to be, and whether they are safe or not.

The GXV3610 series is a powerful tool in this regard. It is weather-proof Infrared fixed dome HD IP camera of outstanding performance and quality. Its advanced ISP (Image Sensor Processor) powered with state-of-the-art auto-exposure/auto-white-balance algorithm and a high quality lens, ensures high fidelity video quality that matches digital still camera color grade in a wide range of light environments.
