Abstract:
PROBLEM TO BE SOLVED: To provide a method for implementing a firewall in a firewall architecture. SOLUTION: This architecture includes a plurality of network layers and a first firewall engine. The layers send packets and packet information to the first firewall engine, maintain packet contexts, pass the packet contexts to subsequent layers, and process the packets. The first firewall engine compares the packet information with one or more installed filters, and returns to the layers an action indicating how to treat the packets. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
A computer system facilitates concurrent filtering and fast-forwarding of network packets. The computer system includes a network card for interfacing with multiple computer networks, and the network adapter is able to fast-forward network packets that it receives to other network destinations without assistance from the main central processing in the computer system. A fast-forwarding cache is stored on the network card to facilitate such fast-forwarding. Network packets that are not fast-forwarded are processed by the main central processing of the computer system that may apply filtering to the network packets and route network packets accordingly. The main central processing unit provides routing information to the network card so that subsequently received network packets can be transmitted to the network destinations without intervention by the main central processing unit.
Abstract:
Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.
Abstract:
Un sistema de autenticación implementado por ordenador para evitar el inicio de comunicación de un teléfono (110, 218) basado en IP, protocolo de internet, que inicia una conversación telefónica basada en IP con un destino (112) remoto en unas comunicaciones (100) de voz basadas en IP una vez que un usuario del teléfono basado en IP se ha autenticado previamente con éxito con los datos de identidad de usuario en un servidor (104) de comunicaciones que comprende: un cliente (208) para conectar una llamada del teléfono basado en IP a través del cliente al destino (112) remoto sin necesidad de que el usuario se someta a un procedimiento de acceso complementario en un componente (102, 216) de aplicación, comprendiendo el cliente: un componente (102, 216) de confianza adaptado para recibir unas credenciales pre-autenticadas que contienen los datos de identidad de usuario procedentes del servidor de comunicaciones a través de un protocolo de sesión de medios que es un protocolo de inicio de sesión, SIP; y el componente (106, 210) de aplicación adaptado para proporcionar una comunicación de voz entre el teléfono basado en IP y el destino remoto, a la vez que elude el procedimiento de acceso basándose en los datos de identidad de usuario contenidos en las credenciales pre-autenticadas.
