Peer to Peer - Research Paper Example Moreover, this is usually implemented in P2P systems. The significant solutions are provided for the present problems that are mentioned in P2P systems (RODRIGUES, DRUSCHEL 2010): Application state maintenance Application-level node coordination Content distribution In this paper, interesting techniques along with related example are discussed. II. degree of centraliztion In the stem design, the architecture of P2P system is characterized according to the presence or absence of centralized elements (RODRIGUES, DRUSCHEL 2010). The centralized P2P system may include a committed node controller that helps to manage a set of contributing nodes and control the whole system. For example, the membership as, well as the content index is maintained by the website posse by Napster. Moreover, the initial version includes Bit Torrent ‘tracker’ that helps to keep track of all the uploading and downloading content. Thus provides a set of nodes if connected by peer. The BOINC platform consist a website that help to maintain the membership and allocate other computer related task. The log in system, account management and payment is managed by the Skype that contains a centralized website. In order to transmit content or other computer applications, resource-intensive is utilized. In fact, centralized P2P system can give organic growth and plentiful resources. ... III. decentralization of p2p networks There is no devoted nodes are present that are critical for the operating systems in the decentralized P2P system. In addition, the decentralized P2P system comprise no inherent bottlenecks are present. Moreover, this shortage of devoted nodes prevents the system from potential attacks, failure and legal challenges from the hackers. The nodes contain abundance of resources, high availability and publicly routable IP known as super nodes in several decentralized P2P systems. The rendez-vous point for nodes is considered as extra responsibilities of super nodes. These nodes are present behind firewalls, storing state or keeping an index of available content. In the P2P system, the super nodes can enhance the effectiveness but also it is involve in failure of nodes. IV. Distributed coordination Repeatedly, a number of nodes within the P2P application need to synchronize their activities without having a centralized administration or control. For exa mple, the group of nodes that duplicates a specific object needs to be synchronized for the updates associated with the object. (Sianati, Abbaspour et al. 2011) One more example of a node that is seeking for a specific streaming content segment will be curious to identify the node that is received by that channel i.e. the channel that is within reach and that has adequate upstream bandwidth. In this study we will incorporate two different methods for this issue; the first techniques will be epidemic techniques in which information is scattered virally from the workstation. The second technique will be a tree based method in which distribution trees are constructed for dispersing the information (RODRIGUES, DRUSCHEL 2010). Our primary focus will be on the decentralized

Review of Capital State Arena Coursework Example | Topics and Well Written Essays - 750 words

Review of Capital State Arena - Coursework Example The theatrical lighting system needed for the arena was important because it would be installed in a way that it would light different events; hence, displaying different moods. The committee involved in the lighting of the arena understood that there was a need for the lighting console of the new facility. Therefore, they had to come up with a plan that would make the arena sell during the off-season where no sports were being held (Moser, 2006). However, a lighting console that can change moods, and accommodate different event was computer controlled and the lease rate was at $2,000per day in addition to the operator expenses. The products that were available for the committee were from three different companies. They included the CAE who manufactures Leprecon LP-3000, ETC manufactures of ETC Obsession II and Strand who manufactures Strand 520. The service providers provided a dealer network information, specific information about each console and a warranty repair station list. Therefore, with this information the committee had the expertise of choosing the correct lighting console for the arena. Various features were identified in the three consoles that seemed similar. However, to help in the decision-making process a list was provided to indicate how the committee should select the console. Where the console should be user friendly in the sense that, the programming of the console should only have few keystrokes; hence, eliminating the need to have a technician employed on retainer to keep the system on. It should be accessible to the theatre department where it can be used a teaching aide, especially when it is not in use. The console should be inflatable and the software should be upgradable. This is because today the consoles are computer driven and for that reason, they should be flexible to ensure that they accommodate upgradability. The console should be manufactured in the United
