How Does VPN Work?
The internet is with no doubt the widest and most used computer network existing in the world today. If you need any kind of information, foe business or individual use you can rest assured that you will find it on the internet. There are many kinds of technologies and protocols that are currently being used on the internet in order to ensure that you can enjoy hassle free communication and be able to find the right information you need in the shortest period of time. Businesses in the modern day have really adopted the use of the web and there is no doubt that this trend is not going to change any time soon.
The term Virtual Private Networks is commonly used in computer networking to refer to encrypted data transfer capabilities in networks. If you are a business owner and you want your staffs to be able to communicate with outside parties through the use of the internet, the use of VPN is definitely something that you cannot choose to overlook. VPN will assure you of your security and privacy since the data you will be sending would not be open to the general public. You can connect both multiple and remote users on the same platform through the use of a direct pathway. If you can install a VPN in your business network today, you would no longer have to make use of wide area networks any more. Moreover, such a step will help to simplify the needs of your company.
In order to build a secure VPN, you would require scalability, reliability and also the management of network policies that are designed for purposes of overseeing the functions of the network. If you want to use VPN, you can choose to contract the services to another company or you can choose to manage the whole element by yourself.
How VPNs work
The use of VPNs involves some special vocabulary which helps to describe the components that are in the network. Nodes in networks are the terminals or the points where the connecting lines intersect. The nodes found in the network have got a server or router that is used to monitor the operations in the network. The use of network access servers is also a major feature of VPN and basically allow for entry in and out of the network. The use of protocols is also present in VPN settings. These protocols help to ensure secure and controlled connections.
Before you can install VPN on your network, there are elements that are called service level agreements that have to be agreed on. These agreements basically define the kind of services that the VPN provider will be able to offer a customer. If you thought that a VPN works in a similar manner to point to point connection that is definitely not the case. The topologies used in VPN arrangements can be quite complex and therefore it is important to ensure that you have effective avenues for the delivery of customer traffic.
Remote access VPN
There are two major categories of VPN: site to site and remote access VPN. Remote access VPN is also referred to as virtual private network. If you run a company and you have a very large number of remote users, this is the kind of network arrangement that you need to implement in your premises. Since they would be calling from various locations in the state and even in the Diasporas, it is always important to make sure that they are communicating in a secure manner. The use of encryption also helps to make sure that the connection is much secure and private.
Site to site VPN
This kind of VPN is normally used where people in multiple locations have to be connected in a secure manner. Experts also refer to this kind of an arrangement to as a site to site extranet.

Is Using a Proxy to Watch Online TV Illegal?
It is not illegal, and being able to watch online TV from abroad has been made much easier through the use of proxy servers like the HideMyAss Proxy server that will allow one to watch streaming TV, regardless of where the viewer is located.
What exactly, is a proxy server?
It is a good question, and here in a nutshell is the answer. In this instance the meaning of the word proxy server refers to being able to watch online TV from any country in real time. All of the broadcast stations (ABC, BBC, NBC, FOX, etc.) license services such as Hulu, or appleTV or iTV to re-broadcast, or podcast, or stream those television shows to the viewing public. There are a lot of restrictions that apply however; being in the country of the origin of the television broadcast is one of them. If you are an American in another country like England, or Germany, if you try to access Hulu, you will just be told that you cannot do it due to access restrictions based on your country or locale. (The place that you reside or currently work.) This is where a proxy server comes in. In this case your proxy server would be a separate 'server' or computer that filters and handles the request to Hulu or appleTV from a separate and geographically correct IP address in order to allow you to get to the resources, or television content that you wish to view. Proxy server companies are set up in order to provide proxy IP addresses to the service, or streaming TV resource they are tapping, in order to be able to turn around and send that data stream on to you, the proxy server television viewer.
If you are feeling particularly daring, or you have a great deal of technical savvy; you could set up a proxy server of your own at home, but you should be very familiar with what you are doing. The point behind proxy servers large and small is to assist any client or person to be able to access the information, data or video stream that they need to get, without being hampered by country to country restrictions. Many big corporations use multiple types of different proxy servers in order to filter huge volumes of email or information throughout the entire company.
Using a proxy server to view real time television content via the web is not illegal, but it is getting harder and harder for the proxy server companies to 'fool' (as it were); the large broadcasting companies. So enjoy it while you can, and keep an eye on the latest updates for proxy servers worldwide.
What Future For Australian BlackBerry Users?
RIM continues to deny claims of them being labelled as a company rapidly losing everything. Corporations in Australia have already prepared a major shift from BlackBerry devices to other alternatives. In this case, many have started opting for Apple based products.
Corporate customers have been actively seeking opinion from others of the kind of products they ought to shift to in case RIM falters. While a majority are busy preparing for the death of RIM (in case its BB 10 ends up being a dud next year), some have already moved quietly to other brands.
RIM is mulling over plans to become better. The Waterloo-based company's shares dropped significantly over $20 USD a little over a year back. Earlier this week, RIM is taking another fall as its shares dropped to another $8 USD. With bad news becoming an everyday thing, the company is looking to cut more jobs. The announcement of a delayed release of the BB 10 contributed to the loss of stock shares. RIM is begging for investors to give them several more months to sort things out. Developers are currently working hard around the clock in perfecting its new platform.
Financial losses forced RIM to replace a majority of their senior staff. This also includes executives from RIM's Australian-based headquarters in Melbourne. After Australia's longest serving RIM CEO stepped down early this January, it took two replacements before finally settling with its current CEO, hired recently this week.
Corporate consumers have been making inquiries of RIM's project plans, an analyst reports. Calls have been made involving details of how the Canadian company would approach with their new plans of tackling short term projects.
Even though BlackBerry is steadily losing ground in terms of corporate use, the product is still sought after. This is mainly due to RIM's trusted and worthwhile security features and reliable - not as effective as other brands in the market at the moment. BlackBerry is still widely being used in today's biggest firms. If its new platform in the BB 10 fails to impress as promised, RIM could be positioned for a huge fall deep into the abyss.
RIM has a stake of over 50% corporate users who use BlackBerry devices like the Torch 9810 for work related functions. It is therefore crucial for them to not be sidetracked as this could seriously lose them a lot of customers. Corporate clients are asked to be aware of RIM's status before ringing alarm bells. Although enterprises are well aware of the situation, some have prepared contingency plans. Australia's biggest companies are already making their move in case RIM falters. Others have quietly made a shift to Apple based products.
Meanwhile, major firms in the United States are threading carefully. In case RIM does lose out and its BB 10 operating system fails miserably, contingency plans have been set.
The UNIC Logo
A logo is designed to be immediately recognized by the viewer. Hence, it should display basic design principles.
The UNIC logo is composed of three letters with the same shape that represent the offered services: internet, video and audio. While the "I" symbolizes the utent and the red spot stands for the satellite.
UNIC Services
The set of primary services constituting the must of UNIC are commonly gathered under the term of Triple Play services. These are mainly entertainment services using the TV set as a universal gateway for consumers at home. They all present some differences compared to the usual Triple Play services offered today. Another set of services is further defined to exploit the possibilities of UNIC to provide new original features to consumer or to extend them to business users.
The list of defined services is not exhaustive neither it is supposed to be supported entirely by the UNIC project. This list is solely intended to provide a general overview of the possibilities of UNIC in the context of TV evolution.
Real Triple Play
Beyond Internet services: Web2TV, Email2TV, Chat2TV, Music Download/Playback, Online Gaming, Home on Demand Gaming, Extreme Online Role-Playing Game (XORGS) Audience, Cyber-Gaming. Internet TV-centric services are mostly intended for people who do not own computers in order to make the World Wide Web available to everyone.
Beyond TV services: SD/HD TV, Personal TV, Interactive TV, Interactive TV return Channel, Personal Video Recording (PVR), Time Shifting (TS), Video on Demand (VoD), Electronic Program Guide (EPG), Mosaic. Several of these are already delivered by terrestrial and satellite Digital TV providers using the current PSTN return channel for interactive services. Exploiting the satellite return channel combined with the DVB-S2 technology will allow UNIC to be an attractive alternative.
Beyond phone services: Phone2TV, Video Conferencing. The TV-Centric structure will ensure that any person with a TV set can potentially communicate with voice and/or video with one or more other distant persons. These services already exist on terrestrial broadband but require a computer, a webcam and adequate video conferencing software. Having a TV-Centric video conferencing service available to any person owning a TV would have a great impact on the business context, considering that it provides a turnkey solution for video conferencing.
More Services
Surveillance and monitoring services: Home/Office Surveillance/Automation, Weather Monitoring, Crop Monitoring & Management. These services are designed mainly for industrial applications in developed area and to meet local governments’ needs in rural areas in developing world.
Tourism services: Interactive Travel Channel, Virtual Cultural Visit (VCV), Real Estate Timeshare Information, Nightlife Events Information, Weather Forecast. It will be possible to access to tourism information in remote areas lacking Internet connection.
Other services:Bringing Courses Into Home, TV All Together, Live Announcement, Assisted Living, TV Health Centre. UNIC can give a large contribution to the continuing trend of distance learning and home-based care services reshaping the way consumers use Digital TV.
How UNIC works
The main application scenario of the UNIC system is a remote village not served by terrestrial broadband infrastructures (i.e. ADSL, WiMax,...). The UNIC system is therefore designed to provide (i) broadband connectivity (triple play) to the homes, via a bi-directional collective satellite gateway (e.g., serving a village, a group of houses, a large multi-storey building,...), and (ii) conventional TV/HDTV services via Direct-to-Home (DTH) reception. The user STB, allowing seamless access to the various services independently from their origin/transport infrastructure, is typically an hybrid DVB and IP box connected:
*
to the collective gateway trough a wired or wireless local broadband network (for interactive services),
*
to the DTH receiving antenna through the home cable network (for TV/HDTV services)
The user/home segment, in addition to the fixed equipment (STB, TV/HDTV monitor,..) , includes also a variety of handheld electronic devices (mobile phones, PDAs,...). Alternative scenarios are also considered, implying different implementations of sub-systems in the collective gateway and in the user STB.
In order to fulfil these system requirements, the UNIC end-to-end system is composed of the following segments
1. the User /Home Service Segment
2. the Collective Service Segment
3. the Transport Media Segment and
4. the Ground Service Segment
What is UNIC
The UNIC FP6 project intends to address the digital divide by developing low-cost satellite-based technologies that will support the provision of TV-centric triple play services to rural areas.
The provision of triple play services - TV, broadband internet and telephony - is currently a major growth area with satellite, telecommunications and cable companies competing to become sole providers of these three services to households within Europe. Aside from offering consumers a single bill, triple play provides opportunities for converged information and communication applications. However, while the broadband networks that underpin triple play have extended to most urban centres within Western Europe, many rural populations and some urban centres in Europe still access the internet through slow dial-up lines. Thus, having put up with rudimentary use of internet based services the inhabitants of these areas now face exclusion from newly converged interactive and entertainment services.
The UNIversal home satellite Connection (UNIC) project is attempting to address this existing and potentially growing urban-rural digital divide by developing novel satellite-based technologies that will support the provision of triple play services to rural areas. At the same time, UNIC seeks to bridge the digital divide that arises from the lack of computer ownership and/or computer literacy by providing interactive services such as email and web browsing on standard TV sets.
UNIC Project
UNIC (UNIversal satellite home Connection) is a Specific Targeted Research Project (STREP) funded by the European Community under the Information Society Technology Framework Programme 6 for Research and Development.
UNIC aims to study and test attractive means to offer interactive multimedia services over low cost 2 ways satellite terminals, down to the TV set of the users. Beyond its wide geographical coverage capacity, the satellite solution has the potential to supply several simultaneous channels to the home, (including HD bouquets), matching the whole family composite needs.
Bringing it all to the TV set cuts another major factor of digital divide (# 100 % TV equipped households, compared to #50-60% PC equipped).
The project is led by Thales Alenia Space France. The other project partners are: Eutelsat SA, MBI, Centro Ricerche RAI, Università di Pisa, Kreatel AB, Wind Telecomunicazioni, CNES, University College London
