Recently, it was revealed that the European Union has made a decision to inspect whether Internet service providers (ISPs) are providing equal access to online services. This looks like a step towards the new laws that are formed for banning the ISPs from confining the access to data-heavy services. However, ISPs said that traffic management is a solution for maintaining the quality services. EU’s declarations fall short of the demands of net-neutrality activists, who want all traffic to be treated fairly. The investigation is carried out for both mobile and fixed providers and will be revealed by the end of the year. While announcing the new decisions, the EU’s commissioner for the digital memorandum unveiled that they are completely determined for everyone in the Europe should get equal opportunities to enjoy the benefits of an open and legalized internet services, without any hidden restrictions or limited speeds that they have been assured of.
The Commission has requested the Body of European Regulators for Electronic Communications (Berec) to commence a rigorous fact-finding task on the issues that are crucial for an open and fair internet services. Moreover, the further plans are to attach the businesses and clients to highlight the ISP’s drawbacks, and if the results indicate outstanding problems they will take actions in the near future, on the following issues. If actions to improve competition are not sufficient to bring internet providers to offer real consumer choice, than European Union is ready to prohibit the blocking of legal services or applications. The committee also agreed that there are some services which should be slowed down to permit others to work.
During a survey of EU, it was found that the consumer’s experience is not exaggerated if an e-mail reaches him in few sec’s after it has been send. On the other hand, a similar setback in a voice chat would cause it to be considerably degraded, if not delivered is entirely useless. Consumer’s pressure or media scrutiny will make the providers from jamming or charging for extra bandwidth-heavy services. Some campaigner’s are worried about the net-neutrality. It is a concept the concept that is available to all services on the internet should be equally shared. They had expected for a firmer verdicts from the commission, and fret that without stricter actions ISPs may start charging companies for unlimited access to its users.
All this circumstances are now creating a two-tiered internet because the big enterprises are offered faster access to its clients, while, the smaller businesses suffer aside. Advocates of net-neutrality are resolute that a fair internet is very important for further competition and innovation, and strategies to prevent such practices should be put aside. The Internet services, after all is about openness, selections and participation. If ISPs mistreat their power of Internet traffic, then these necessary qualities are lost.
Alcatel-Lucent will introduce new technology for wireless carriers to expand their network. The new technology is a new cell phone antenna system that puts together the technology in a small box, which can be mounted even on a lamp post. The Light Radio system from Alcatel Lucent will be ready for the trial of the carriers this year, allowing carriers to set up new cell sites faster and economically. The cell phone tower technology being shrunk fits more easily the budgets of the carriers. It is economically more viable to use a cell site which comes with an antenna.
The data processed, is expected to rise by 26 times of what it is now, by 2015, as per the reports from Cisco, on their forecast on the index for visual forecasting, conducted each year by them. Alcatel–Lucent has potentially changed the structure of the cellular network by reducing greenhouse emissions and bringing mobile broadband into new areas. Called Light Radio, the technology was showcased in London by Alcatel–Lucent’s partners Freescale and HP. It reduces the size of the technology from a filing cabinet to a small box. Apart from helping the industry reduces costs it would also reduce carbon dioxide emissions.
The way the carriers are gearing up for the increase in data is by adding more possible capacity to their networks to carry the traffic from radio towers to the Internet. The industry cannot provide more spectrum to carriers since there are limits to the amount of mobile data that can be transmitted on a given spectrum. One way that they can use to mobilize more spectrum is by deploying more cell sites in smaller sized area. Many carriers have already started using smaller sized cell sites and are also providing more bandwidth, for example providing personal cell sites for the home or business. To improve the indoor wireless coverage, cell sites are connected to a broadband connection to give leverage.
However, this task involves using new cell towers, which is expensive and not always feasible. This is where the Light Radio technology comes in from Alcatel-Lucent. It allows carriers to deploy smaller cell sites at less operational costs. They start with replacing larger towers with smaller cell sites. This way the carrier expenses on cell sites are cut to a bare minimum. Also, the connectivity provided to users is on broadband using cloud computing.
Therefore, with the Light Radio system, it is possible to create economies of scale; the antennas used are software configurable and reusable equipment even in the event of changing technologies like 2G, 3G, 4G etc., accessible from the same point of dispersion. This development will bring a change where carriers have to deploy and change hardware with every change in technology. The cell tower technology has been shrunk to fit the budgets of carriers and it is a major breakthrough in the technology of cell sites.
A need to upgrade the currently used IPv4 has been felt for quite some now to handle the wildfire like growth of the network. But experts have tried to justify their refusal to adopt IPv6 by taking support from some preset misconceptions. It is high time that we cleared our minds of these misplaced notions because due to the rapidly growing network we are soon going to fall short of IPv4 addresses.
Amongst the biases the following are the biggest misconceptions that have been doing rounds recently:
Black Marketing of IPv4 Addresses – There is a fear that the introduction of IPv6 will trigger black marketing of IPv4 addresses. In the views of the experts, in anticipation of the rise of this problem, the regional Internet registries have devised legal ways of transferring and selling the unused IPv4 addresses. It is feared that this problem may catch the experts off-guard because not much is being done by the IT departments and vendors towards this. A new policy is being considered by the regional Internet registries that will allow the transfer of IPv4 addresses. One more instance in this case is the step taken by ARIN that has announced that it would make sure that the addresses are used to provide network services and are not hoarded for future use or for black marketing.
IPv6 believed to be more secure – A myth goes around that IPv6 is more secure than IPv4. The reason why this is assumed is that IPv6 was designed with a view to implement the IPsec much more efficiently. But this doesn’t make sure that IPv6 is in itself more secure.
Adoption of IPv6 not yet required – Most of the companies have not yet made any move towards starting development work on IPv6. No amount has been laid aside for investing on this project. A large number of the experts are under the impression that the introduction of IPv6 can be delayed as there is no urgency for its adoption.
IPv4 addresses still available in large numbers – Another misconception is that the IPv4 addresses are still available in plenty. Our thinking whether IPv4 is fast running short of addresses depends on the place where we live and how fast is the rate of growth of the network. A huge shortage in IPv4 addresses has been predicted for the present year. Chris Davis, senior director of corporate marketing communications at NTT America (a leading provider of IPv6 transit and access services in USA), has called this depletion of IPv4 free address pool as a wake-up call.
Internet will be more simple with IPv6 – It is believed that IPv6 will make using Internet much more simple as its introduction will lead to discontinuation of usage of Network Address Translation (NAT) and also the removal of middle boxes, which were being used earlier to prolong the life of IPv4 addresses. But little do they realize that for some time IPv4 and IPv6, both the versions will be put to use simultaneously.
Lucky ones will get hold of the remaining IPv4 addresses – The IANA has already used all the IPv4 addresses in the month of February. Now the remaining addresses will be transferred by the regional Internet registries. According to estimates, the African registry, AfriNIC, is expected to finish last with these addresses. A one-time allotment policy will be followed. The last IPv4 addresses would be shared with multiple users.
