Virtual Private Network Essay Example for Free

Virtual Private Network Essay VPN Defined: So what is a good definition of Virtual Private Networking? Simply defined, a VPN is a â€Å"virtual† network that is kept private by â€Å"tunneling† private data through the underlying infrastructure of a public Internet. VPN technology provides a way of using public network infrastructures, such as the Internet, to provide private, secure access to applications and company resources to employees in remote or home offices, to business partners, and even to customers. A VPN is one or more WAN links over a shared public network, typically over the Internet or an IP backbone from a Network Service Provider (NSP) that simulates the behavior of dedicated WAN links over leased lines. VPN technology uses a combination of tunneling, encryption, authentication, and access control mechanisms and services used to carry traffic over the Internet, a managed IP network or a service providers backbone. VPN allows the data to be shared between the client and a server, between two servers, or between networks or routers via a public network but it works just like a point-to-point private line. VPN network architecture uses the remote PC (installed with a client software) that makes use of the present telecommunication infrastructure technology like for example phone lines, broadband services, dedicated internet link etc. and a tunneling protocol (incorporated with other authenticated and encrypted protocols) to access the corporate resources like files, emails etc through a VPN server which sits at the perimeter of the corporate network. The diagram that is seen below shows the simple VPN structure between a client and a server: VPN is a private network that is layered over the public networks for example Internet to connect to the remote sites and remote users with the privacy, security, quality of services with always on connectivity with well manageability features like the leased networks have. A typical VPN structure with remote offices business partner’s mobile users of the organization connected to the main office through the network services providers point of presence (Pops), looks like the one below shown in the diagram:

Los problemas de D. Davidson con la acción intencional :: Spanish Essays

Los problemas de D. Davidson con la accià ³n intencional ABSTRACT: Es este trabajo quisiera exponer las dificultades que el modelo de explicacià ³n de la accià ³n propuesto por Donald Davidson tuvo a la hora de explicar la intencià ³n. En su primer modelo, Davidson habà ­a explicado la accià ³n a partie de deseo y creencia, à ©stas no sà ³lo racionalizaban sino que tambià ©n causaban la accià ³n; y accià ³n e intencià ³n se identificaban. Sin embargo, Davidson repara posteriormente en que, por un lado, a veces el deseo y la creencia parecen tener como resultado la accià ³n y, sin embargo, no se da entre ellos la relacià ³n causal 'adecuada,' por lo que no podemos decir de la accià ³n que sea intencional. Son casos de cadenas causales irregulares o no està ¡ndar. Por otro lado, a veces tener un deseo y una creencia relacionada no nos conduce necesariamente a la accià ³n. Y, aà ºn en el caso de que nos conduzca a la accià ³n, à ©sta puede ser contraria a lo que nuestro mejor juicio nos dicta. Este es el problema de las con ductas irracionales. Ambos problemas causaron que introdujera algunos cambios en su modelo inicial. Sostengo que estos cambios no mejoraron el modelo. El problema de las cadenas causales irregulares no se resuelve, y el problema de las separacià ³n entre deseo-creencia y accià ³n se reformula en tà ©rminos là ³gicos, mediante un recurso tà ©cnico. En 1963, Donald Davidson publica un artà ­culo "Acciones, razones y causas" que significà ³ la reunificacià ³n de dos modelos de explicacià ³n tradicionalmente separados: el racionalista, segà ºn el cual las razones explican la accià ³n porque la justifican; y el causal, que mantiene que la accià ³n sà ³lo se explica mediante sus causas. El planteamiento de Davidson disuelve esa oposicià ³n: "la racionalizacià ³n [dice Davidson] es una especie de explicacià ³n causal ordinaria". (1) No tratarà © aquà ­ muchas de las crà ­ticas y problemas que suscità ³ y sigue hacià ©ndolo este planteamiento del tema, como la conexià ³n là ³gica que hay entre razà ³n y accià ³n o la necesidad de que exista una ley que respalde esa conexià ³n. Mi objetivo es observar si este modelo puede dar cuenta de la intencià ³n, de ese momento previo a la accià ³n. Los problemas que el tratamiento de la intencià ³n supusieron para el modelo causaron una reformulacià ³n de à ©ste. Estos problemas fueron (1) las cadenas causales irregulares o no-està ¡ndar (externas o internas); y (2) aquellos casos en los que o bien el deseo no conduce necesariamente a la accià ³n o bien los sujetos actà ºan en contra de su mejor juicio.

Elevator Speech Audience: Diana Gale Purpose: To outline strategies for developing a publicly supported wasteland augment policy â€Å"Seattle Waste utility faces a challenging new mission: not only is the agency t asked with its previous responsibility of delivering waste management services, it is now task ked with developing waste management policy. With the approaching deadline to Rene w the contract with the King County landfill, the utility is faced with an opportunity to recon mend a new longer waste management policy.You have already accomplished a great deal by building SSW into an organize Zion that can be effective in developing policy, but local organizations, politicians and meme beers of the public have strong, competing perspectives about waste management in Seat tale. In addition, confidence in Saw's ability to recommend a policy is low. Under these conditions, it is best if SSW does not make a recommendation a bout a longer waste management policy alone. Instead, yo u should engage key organization s and individuals whose support could strengthen Saw's legitimacy.TO determine a longer asset disposal policy, we recommend that you pursue one of two participator decommissioning processes: the first includes the the public, along with local p Laotians and administrators. If time constraints allow, we feel that this is your best bet to in crease Saw's legitimacy and gain support and cooperation for the policy. The second excels vilely includes local politicians and administrators. This second process would increase the u utility legitimacy on a more limited level, but may be preferable if time constraints prevent you from pursuing the more inclusive process. †

Cuban Writer Reinaldo Arenas - 1499 Words

During an interview in 1983, printed in the New Yorker just last year, Reinaldo Arenas was asked, â€Å"Does a writer have a duty to himself and to society?† Arenas replies that it is indeed the job of the writer to write their best, but defines that as â€Å"when a writer writes, he’s always referring to a social and historical context.† Arenas was a Cuban writer, exiled for being openly homosexual and rebelling against the Cuban government through his written works. He was also very autobiographical in his work, and as it would appear in his New Yorker interview, this is where his passion and writing flourished. Reinaldo Arenas used his own marginalized voice as openly homosexual man in Cuba and commentary on Castro’s regime to challenge the†¦show more content†¦Castro’s revolution placed the utmost importance on the society and called for a surrender of the individual. By 1965, Castro created UMAP camps (Military Units to Assist Producti on), which were agricultural labor camps operated by the Cuban government. The camp’s inmates consisted of gay men and any other â€Å"counterrevolutionary† kind of people. It was in one of these camps where Arenas placed his fictional character, Arturo, in his story â€Å"The Brightest Star.† This is a fictional story of Arturo’s experience in one of these labor camps. Arenas’ motivation for writing is very apparent in this work as he, as opposed to the Cuban regime, is in full support of the individual and their right to express themselves even in a very oppressed state, in this specific case a labor camp. Arturo is a dreamer and uses his writing to create and alternative world to rise above the real world oppression. When Arturo was first selected to be taken to the camp, Arenas employs the use of gay stereotypes by the officials in choosing who to arrest, â€Å"young men being carried out these days under the absurd pretext that one young mans hair was too long, or that another wore clothes of a certain cut or (most fatal) exhibited certain telling traits, had certain ‘mannerisms’† (65).
