Cisco launches super fast router.....

NETWORKING HARDWARE VENDOR Cisco announced a router that it thinks could change the world wide web for evermore.The company said its glorious CRS-3 carrier-grade router is designed to serve as the foundation of the next-generation Internet, as it can manage speeds of up to 322 Terabits per second.

Just so the great unwashed know, that is fast enough to transmit the entire printed collection of the US Library of Congress in one second, or the bandwidth required for every man, woman and child in China to make a video call, simultaneously. Every movie ever created could be streamed in less than four minutes, Cisco claims.

Of course it is just a router and not the entire world wide web infrastructure, but it has more than 12 times the traffic capacity of anything else out there.Cisco says that it will make Internet and cloud services much more efficient. It mentions that AT&T recently tested the Cisco CRS-3 during the world's first field trial of 100-Gigabit backbone network technology, which took place over AT&T's live network between New Orleans and Miami recently.

The CRS-3 machine will replace the firm's CRS-1 router, which is still one of the most popular and fastest available commercial routers. The CRS-3 is three times faster than the CRS-1.The firm says its latest top of the line carrier-grade router is powered by its Quantumflow Array Processor, which unifies the combined power of six communications processor chips to work as one. This apparently will deliver high service capabilities and processing power. It also will require only a fraction of the power.

Cloud security weaknesses prompt call for global data protection law

European leaders have called for a worldwide agreement on data protection to address the data security weaknesses of cloud computing.The call was made today before an international audience of 300 cyber law experts who had assembled at the Council of Europe to discuss the harmonisation of cybercrime regulations.

Francesco Pizetti, president of the data protection authority of Italy, warned that cloud computing had challenged the legal basis on which personal data was handled by corporations."It is not possible to continue to guarantee the protection of citizens' data without very strong international rules accepted by all countries around the world," he said.

Udo Helmbrecht, executive director of the European Network and Information Security Agency (ENISA), said the agency was examining cloud computing because of the risks it held for data security.ENISA will push for European regulation to oblige cloud providers to notify customers about security breaches, said Helmbrecht.

"We need to build trust into the cloud," he said. "If we don't build trust into this environment, the business model will not run."

Jim Reavis, executive director of the Cloud Security Alliance, said the regulatory environment needed clarifying for cloud providers. One uncertainty was how to deal with government requests to access the data they held. Cloud providers might want to make it difficult for "adverse" governments from getting at their data, but should assist governments who had the legal authority to make requests."We don't have a lot of good rules and structures for doing that sort of thing," he said. "There's a lot dealing with the legal domains, there's a lot dealing with incident response, there's a lot with the technology of cloud that we need to secure."

Yves Poullet, director of the Research Centre of IT and Law at the University of Namur, warned that "cloud computing is challenging the definitions of privacy" and foreign police might seize data contained in cloud datacentres hosted in their country.Pizetti said an EU desire for better cloud regulation had been prompted by the US seizure of European banking data held by Swift - a move that caused the firm to close its US datacentres.He said the Council of Europe's Convention on Cyber Crime would help create an international system of regulation that would make cloud computing safer.

The Council of Europe's annual Octopus conference was a focus for efforts to harmonise cyber laws around the world, mostly to give law enforcers the legal basis on which to gather cross-border evidence and bring prosecutions for cybercrimes such as hacking and fraud.Alexander Seger, head of economic crime at the Council of Europe, warned that European businesses did not want to use cloud providers who hosted datacentres in countries that did not have adequate legal protections.

Jorg Polakiewicz, head of law reform at the Council of Europe, said both the Convention of Cyber Crime and the Council of Europe's Data Protection Convention were being updated to take account of new technologies such as cloud computing.

LocalTalk

LocalTalk is a network protocol that was developed by Apple Computer, Inc. for Macintosh computers. The method used by LocalTalk is called CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance). It is similar to CSMA/CD except that a computer signals its intent to transmit before it actually does so. LocalTalk adapters and special twisted pair cable can be used to connect a series of computers through the serial port. The Macintosh operating system allows the establishment of a peer-to-peer network without the need for additional software. With the addition of the server version of AppleShare software, a client/server network can be established. The LocalTalk protocol allows for linear bus, star, or tree topologies using twisted pair cable. A primary disadvantage of LocalTalk is speed. Its speed of transmission is only 230 Kbps.

Wireless LAN

Not all networks are connected with cabling; some networks are wireless. Wireless LANs use high frequency radio signals, infrared light beams, or lasers to communicate between the workstations and the file server or hubs. Each workstation and file server on a wireless network has some sort of transceiver/antenna to send and receive the data. Information is relayed between transceivers as if they were physically connected. For longer distance, wireless communications can also take place through cellular telephone technology, microwave transmission, or by satellite.Wireless networks are great for allowing laptop computers or remote computers to connect to the LAN. Wireless networks are also beneficial in older buildings where it may be difficult or impossible to install cables.

The two most common types of infrared communications used in schools are line-of-sight and scattered broadcast. Line-of-sight communication means that there must be an unblocked direct line between the workstation and the transceiver. If a person walks within the line-of-sight while there is a transmission, the information would need to be sent again. This kind of obstruction can slow down the wireless network.

Scattered infrared communication is a broadcast of infrared transmissions sent out in multiple directions that bounces off walls and ceilings until it eventually hits the receiver. Networking communications with laser are virtually the same as line-of-sight infrared networks.
Wireless LANs have several disadvantages. They provide poor security, and are susceptible to interference from lights and electronic devices. They are also slower than LANs using cabling.

Bluetooth Technology

First of all, I want to told you from where word “Bluetooth” came, it put on the name of a great Denmark king whose name was “Harald Bluetooth” a thousand years of ago. Now the question is, what is bluetooth technology, actually it is a technology which is used for low-power radio communications to wirelessly link phones, computers and other network devices over short distances. Initially it was developed for support of personal wireless devices including cell phones, PDAs, and wireless headsets.The signals that are transmitted through “Bluetooth” devices are short distance in nature, They diminishes after 10m(30 feet).The data transferred through Bluetooth devices is at a rate of less than 1Mbps.As I already told you “Bluetooth” devices works on the principle of radio communication systems, so it is not required that the two Bluetooth devices must be in line of sight of each other, they can be either in different rooms, as long as the received transmission is powerful enough.

Today,there are many bluetooth enabled devices exists such as phones, printers, modems and headsets etc. This technology is useful only when the Bluetooth enabled devices are present in low- bandwidth position. Today Bluetooth is mainly used in cell phones to transfer sound data, or text data with laptops, and from Bluetooth enabled devices.From the security point of view, the data transferred between blue tooth devices is encrypted through some custom algorithms so that it can be safely transmitted. Hence, we can say that data transferred through Bluetooth devices is secure.As, the work is going on the development of Bluetooth so that it can be made more faster,simpler in comparison to other wireless technology.
