Description

MÉTODO PARA LA REALIZACIÓN DE UNA COMUNICACIÓN DIRECTA ENTRE TERMINALES DE COMUNICACIÓN TALES COMO COMPUTADORAS METHOD FOR CONDUCTING A DIRECT COMMUNICATION BETWEEN COMMUNICATION TERMINALS SUCH AS COMPUTERS
La presente invención se refiere a un método para la realización de comunicaciones directas entre terminales de comunicación tales como computadoras, siendo dicha comunicación realizada a través de una red de comunicaciones tal como una LAN, WAN, Internet y/o similares.The present invention relates to a method for the realization of direct communications between communication terminals such as computers, said communication being carried out through a communication network such as a LAN, WAN, Internet and / or the like.
Como es sabido, cada vez son más las herramientas que se utilizan para realizar comunicaciones entre usuarios de ubicados dentro de una Intranet, LAN o WAN. Dichas herramientas generalmente consumen una porción importante del ancho de banda sobre la cual se establece la comunicación. Al consumir tal porción importante de dicho ancho de banda de la conexión, la mayoría opta por utilizar programas que se limitan a la comunicación de sólo texto, es decir no utilizan transferencia de audio y/o video. Cabe mencionar que dichos programas dependen generalmente de un servidor por el cual se manejan las comunicaciones, dado que cada usuario está identificado ya sea por un nombre o nick o por un número UIN (Universal Internet Number) o incluso por una dirección de e-mail. Dado que dichos servidores no son ciento por ciento estables por lo que la comunicación entre usuarios no siempre puede realizarse. Como solución a estos inconvenientes del uso de al menos un servidor para prestar el servicio de comunicación, se ha desarrollado una tecnología denominada peer to peer networking o puerto a puerto, en donde mediante una aplicación instalada en la PC de los usuarios, éstos pueden comunicarse sin la necesidad de dicho servidor. Lamentablemente, dicha tecnología requiere un ancho de banda considerable para realizar una comunicación aceptable y fluida.As is known, more and more tools are used to communicate between users located within an Intranet, LAN or WAN. Such tools generally consume a significant portion of the bandwidth over which communication is established. When consuming such an important portion of said connection bandwidth, the majority choose to use programs that are limited to text-only communication, that is, they do not use audio and / or video transfer. It should be mentioned that these programs generally depend on a server through which communications are handled, since each user is identified either by a name or nickname or by a UIN (Universal Internet Number) or even by an e-mail address . Since these servers are not one hundred percent stable, communication between users cannot always be done. As a solution to these inconveniences of using at least one server to provide the communication service, a technology called peer to peer networking or port to port has been developed, where through an application installed on the users' PC, they can communicate without the need of said server. Unfortunately, such technology requires considerable bandwidth to perform acceptable and fluid communication.
Es entonces objetivo de la presente invención proveer un método para la realización de una comunicación directa entre terminales de comunicación tales como computadoras sin la utilización de un servidor que oficie de nexo entre dichas computadoras. Es otro objetivo de la presente invención proveer un método para la realización de comunicaciones directas entre terminales de comunicación tales como computadoras utilizando sólo una mínima porción del ancho de banda utilizado para la conexión.It is then an objective of the present invention to provide a method for the realization of a direct communication between communication terminals such as computers without the use of a server that acts as a link between said computers. It is another object of the present invention to provide a method for conducting direct communications between communication terminals such as computers using only a minimal portion of the bandwidth used for the connection.
Es por lo tanto objetivo de la presente invención proveer un método para la realización de comunicaciones directas entre terminales de comunicación tales comoIt is therefore objective of the present invention to provide a method for conducting direct communications between communication terminals such as

En caso de que dicha cadena sea correcta, se inicia la llamada entre dos computadoras como mínimo, al realizar dicha comunicación se deberá realizar un proceso de verificación, luego del cual se inicia un módulo de recepción para tratar con las variables de comunicación.SUBSTITUTE SHEET (RULE 26) computers, said communication being made through a communications network such as a LAN, WAN, Internet and / or the like, wherein the method comprises establishing direct communication between at least two computers connected to a communications network, said communication being made by an application arranged in each of the computers, said application being comprised of a communication module located in a source file; said module performs the task of verifying the existence of any type of proxy controller in at least one computer, in case there is said controller, communicating to said computer the possibility of sending information but not receiving it, if not when established the communication can receive them, perform the opening of communication ports other than those used by other applications, capture the IP number assigned to at least one computer when connecting to said communications network, verify the connection of at least one computer to the communications network, in the event that said connection exists to send a result to a variable indicating the connection of said computer, in case said connection does not exist, a module for the realization of said connection is executed, once the connection is made said computer proceeds to start listening to the open ports for said communication by means of a command do that responds to a secure sequence of data string. In the event that said chain is correct, the call between at least two computers is initiated, when carrying out said communication a verification process must be carried out, after which a reception module is started to deal with the communication variables.
Para mayor claridad y comprensión del objetivo del presente invento, se lo ha representado en una de las formas preferidas de realización, a título de ejemplo. Con respecto al método de la presente invención, el mismo comprende una aplicación que permite la comunicación directa entre al menos dos computadoras, prescindiendo del uso de un servidor. Como paso principal en dicho método, se realiza la apertura de puertos, dichos puertos son distintos de cualquier otro puerto y abierto y de cualquier otra aplicación utilizada para conectarse a la red o network. Cabe mencionar que como cualquier entendido en la materia podrá apreciar que dichos puertos pueden ser puertos UDP o puertos TCP, siendo los mismos configurables por el usuario. Uno de los puertos se utiliza para el envío de datos y el otro, para la recepción de los mismos. Dado que la comunicación se realiza por medio del reconocimiento del número de IP, el miso debe ser conocido por el usuario. DichoFor clarity and understanding of the object of the present invention, it has been represented in one of the preferred embodiments, by way of example. With respect to the method of the present invention, it comprises an application that allows direct communication between at least two computers, regardless of the use of a server. As the main step in this method, the ports are opened, these ports are different from any other port and open and from any other application used to connect to the network or network. It is worth mentioning that as any person in the field will appreciate that said ports can be UDP ports or TCP ports, the same being configurable by the user. One of the ports is used for sending data and the other for receiving them. Since the communication is done through the recognition of the IP number, the miso must be known by the user. Saying
HOJA DE SUSTITUCIÓN (REGLA 26) número de I P es capturado en una variable que sirve para reconocer al usuario, sólo a modo informativo sin revelar hacia el exterior dicho número.SUBSTITUTE SHEET (RULE 26) IP number is captured in a variable that serves to recognize the user, only for informational purposes without revealing said number to the outside.
Una vez realizada la apertura de puertos, la aplicación verifica la conexión existente del usuario, indagando en dicha computadora si existe un archivo el cual determina el estado de conexión de dicha computadora. En caso de que dicho archivo exista se arroja un resultado TRUE en una variable indicando el estado de conexión de dicha computadora a una red. En el caso de que dicho archivo no se encuentre, se ejecuta un módulo de configuración que, a su vez, ejecuta una aplicación para la configuración de una conexión de dicha computadora a una red, tal como Internet. Al detectar la conexión, se inicia el proceso de escucha o LISTEN de los puertos abiertos anteriormente. Dicho proceso sólo responderá a una secuencia segura de cadenas de datos enviada por cada computadora conectada a dicha comunicación realizándose una encriptación con parámetros propios. Si la cadena de datos es correcta, se establece la comunicación entre las computadoras que iniciaron la conexión y se establece así la comunicación directa. Cabe destacar que la comunicación inicial se genera por medio de un campo, es decir, los usuarios deberán ingresar el número de I P de la computadora a la que sean comunicarse, al realizarse la comunicación dicha computadora envía la cadena de datos segura y la cadena de inicialización en un CASE (función que existe en la mayoría de los lenguajes de programación y funciona como evaluador)Once the ports have been opened, the application verifies the user's existing connection, inquiring into said computer if there is a file which determines the connection status of said computer. If said file exists, a TRUE result is thrown in a variable indicating the state of connection of said computer to a network. In the event that said file is not found, a configuration module is executed which, in turn, executes an application for the configuration of a connection of said computer to a network, such as the Internet. When the connection is detected, the listening process or LISTEN of the previously opened ports starts. Said process will only respond to a secure sequence of data chains sent by each computer connected to said communication by performing an encryption with its own parameters. If the data chain is correct, communication between the computers that initiated the connection is established and direct communication is established. It should be noted that the initial communication is generated by means of a field, that is, users must enter the IP number of the computer to which they are communicating, when the communication is made, said computer sends the secure data chain and the initialization in a CASE (function that exists in most programming languages and functions as an evaluator)
Al momento de que la comunicación se logra entre las computadoras, se inicia un módulo receptor para que con el tratamiento de las variables LISTEN, CASE, etc., se logre el envío de datos sobre la comunicación orientada estándar. En el caso de una comunicación directa entre computadoras, dichas variables se manejan en forma remota desde cada una de las computadoras de los usuarios permitiendo la utilización de una comunicación de dos vías, tal como la tecnología Full dúplex.At the moment that the communication is achieved between the computers, a receiving module is initiated so that with the treatment of the variables LISTEN, CASE, etc., the sending of data on the standard oriented communication is achieved. In the case of direct communication between computers, these variables are managed remotely from each of the user's computers allowing the use of a two-way communication, such as full duplex technology.
El método de la presente invención captura los datos de audio y son enviados instantáneamente en sentencias de cadenas, sin la realización de Streaming (Suministro de paquetes de datos a velocidad constante) haciendo que la velocidad de conexión para realizar la comunicación sea sólo de 1 Kbps, prescindiendo de esta manera del uso de anchos de bandas altos.The method of the present invention captures the audio data and is sent instantaneously in string sentences, without the realization of Streaming (Supply of data packets at constant speed) making the connection speed to carry out the communication is only 1 Kbps , thus dispensing with the use of high bandwidths.
Por otra parte cabe mencionar que el método de la presente invención, al requerir de un ancho de banda mínimo para la transmisión de datos entre computadoras, el mismo permite a dicho usuario utilizar otras aplicaciones que requieran de conexión a una red sin alterar el rendimiento de las mismas. Además, laOn the other hand, it should be mentioned that the method of the present invention, by requiring a minimum bandwidth for data transmission between computers, allows the user to use other applications that require connection to a network without altering the performance of the same. Besides, the

Cabe destacar además, que el método otorga medidas de seguridad tales como la posibilidad de registrar IPs o rango de IP o ignorar los mismos. Además, dicha aplicación cuenta con una verificación mediante nombre de usuario y/o clave personal para validar el uso del método en la máquina instalada.SUBSTITUTE SHEET (RULE 26) Application of the method of the present invention comprises a noise reduction function, which makes it possible to suppress the noise that the communication channels may have by further reducing the bandwidth required for communication between computers. It should also be noted that the method provides security measures such as the possibility of registering IPs or IP range or ignoring them. In addition, this application has a verification by username and / or personal password to validate the use of the method on the installed machine.
