Download file to see previous pages Internet based conferencing eliminates the need of a physical meeting place. One can meet people, exchange information and data, and can share files and notes using electronic means. It also saves cost and increase efficiency of the system as a whole. Cisco recently saved more than $1 million on ISO-compliance training by using video-on-demand instead of in-person sessions (Jackson 2004).
All the internet conferencing products are inherently dependent upon the bandwidth, networking components and desktop hardware supporting them (McKenzie 2005). If the hardware and network lack necessary support features, internet based conferencing could be an effort in turmoil, and may cause loss of time, productivity, and revenue.
An electronic document or file is more vulnerable to unauthorized access. However, the latest software packages that provide internet conferencing facilities have features to provide assurance about the privacy and confidentiality of data. One low cost, and feature rich product is GoToMeeting by Citrix. In addition to the usual features for conferencing, the product offers high security and privacy to the potential customers. The users are provided capability to share only a specific application rather than entire desktop. It helps to make users more confident that they control the software, and not the other way around. Hence, it is similar to a face to face meeting where one can share specific information with other party without having to show the entire knowledgebase to others.
Confidentiality and Availability
To protect against tapping and data security breaches during transmission, GoToMeeting offers 128 bit encryption of all meeting data, and enforce strong end user authentication procedures. There are software, like Elluminates's server based software, which can detect dropout in audio due to a network glitch and can re-send the missing audio, speeding up the feed slightly until it catches up to the real-time feed. This allows minimal loss of information.
Reliability and Flow Control
For the purpose of internet based conferencing, the delivery and convertibility of data packets reaching to destination is very important and critical aspect of a good performance versus a failed session. This is the exact problem the Cisco was facing with regard to video streaming over IP to ensure end-to-end delivery of the video traffic. If each desktop isn't properly configured for video, there are no guarantees that a video feed will be delivered. The company solved this glitch by pushing out standard configurations to all sites that made it easier to handshake among varying protocols.

As the paper highlights network security guarantees authentication, availability, integrity and confidentiality is important to note that “network security is not absolute”.

The security level of any network also depends on the organizational needs where some might deem information highly valuable therefore requiring that only authorized users gain access while others would allow outsiders to access information but ensure protection against attempts to modify...

The Origins of the Second World War

The accord at present is that it was Hitler's resolve to change the basis of European society that took the war to Europe in 1939. It was not essentially the war he was planning for; the facts propose that Hitler was intending to set up Germany for a huge conflict with Russia in the early 1940s. However, indisputably it was a war forced by his persistent pursuit of strategies that stood on race and on space (Henig, 1997).

The Second World War was originated due to the Fascist attack and the failure of democratic powers to prevent this assault. There seem to be a number of reasons for the Second World War to occur. German rearmament started after Hitler left 1932-34 Geneva Disarmament Conference, declaring that as the po...

He had attempted to find meaning in this scheme of things without much success. A key repeated theme is seeming failure to find that true meaning that will justify his existence. What usually happens is that the more Man goes deeper into the search for ultimate meaning, the more he finds nothing. This is confounding, to say the least, and goes to show how useless the search could be. Many people had been doing this search several times and came up with nothing. Out of this seeming hopelessness and uselessness came the philosophical idea of the absurd – that Mans search for individual meaning is bound...
