Broadband Traffic Modeling - Essay Example Broadband also enhances fair computation, reliable storage and easy manipulation of data responsible for maintaining an acceptable quality of service (QoS) level that is deliverable by the network. Communication infrastructure modes, dates back approximately two thousand years ago. This is the time when Beacon systems couriers and advanced communication networks were engineered Owing to the monumental economical demands of the modern world. Traditional networks have been overridden by the technological renaissance that enhances effective Asynchronous Transfer Mode (ATM) scheme, across the network. Traditional infrastructures were developed on separate networks with unnecessary detractors. Voice in a telephone network for example is too noisy and inefficient for burst data communication. Concurrently data networks, that stores and forward massages using computers have a limited bandwidth connectivity that cannot transmit digital images and voice simultaneously. Fibre Optical Transport Network, based on Wavelength Division, Multiplexing and Optical Cross-Connects technology, offer a tremendous transportation capacity. It calls for a frequent manual intervention for updated management. Due to the inconsistency of the Traffic pattern on an integrated system. Network operators are advised to adopt an optical network a smart, automatic real-time system (ION) or Automatic Switched Optical network, for tractability of the changing traffic load information. 2.3.1 Window sizes A smaller observation window harms the network stability; while a too large observation window worsens the network reliability. Research shows that a suitable traffic observation window size improves the offered Quality of Service (QoS) by reconfiguring the logical layer network at the right time and in the right way. Therefore undesirable observation window size might give less accurate information and trigger the operation at the wrong 2.3.2 Multi-Domain. The performance of multi-domain networks, such as differentiated services (DiffServ), guarantees quality of service across the network. Surprisingly network providers hesitate to use it, since enabling and maintaining it on their production networks requires a lot of new know-how and policy management, and they doubt that it will significantly improve the performance and reliability of their over-provisioned networks, or enable new applications. Hence the proposition, to simulate a model of a network connection, between two computers over a fixed multi-domain route in which the network

International security environment - Essay Example As the conventional/traditional military prove itself outdated and no more useful in modern warfare, the irregular threats compel the military to transform its structure and technology. The unique position of the U.S. Military in international security and its leading role in counter terrorism/counter-insurgency compel it to be innovative and refined. From this view point, the future military service can be predicted and it provide due importance to sophisticated training and innovative technology. For instance, the 9/11 terrorist attack forced the government to shape the Office of Force Transformation (OFT) to transform the US Military to be competitive in present and future missions. So, it is quite evident that the future military services will be more aggressive than present. Barnett points out that future may prove the maximization of U.S. Military influence in every nook and corner of the world. Apparently, one who is in military service must be prepared to be in any part of th e world to serve the nation. Besides, Barnett states that globalization leads to increase in standard of living, but some areas are disconnected from its influence and is still underdeveloped. This disconnection resulted in non-integrating gap among world countries, and acts as a threat to national security of the U.S. government. In the work- ‘American defense policy’ by Paul J. Bolt, Damon V. Coletta, and Collins G. Shackelford points out that: â€Å"Our next war in the Gulf will make a historical tipping point- the moment.
