The present invention relates to computer viruses and more particularly to a method and system for requesting a virus-free certificate associated with a file of a file server and downloading this virus-free file certificate or a file including this virus-free file certificate from the file server. The method, for use in a client system (), comprises the steps of: The method, for use in a file server (), comprises the steps of:

System and method for downloading a virus-free file certificate from a file server

A method and system for establishing a Virtual Path (VP12) capability in a Frame Relay network wherein frames are transmitted over a plurality of virtual circuits from a first switching node to a second switching node. A control message is transmitter from the first switching node to the second switching node with a Data Link Connection Identifier (DLCI) having a predetermined value indicating the purpose of the control message which is to define a virtual path aggregating at least two virtual circuits selected from multiple virtual circuits. The control message contains the identification of the virtual circuits aggregated in the defined virtual path.

A system and method for performing interleaved packet processing. A packet includes a source address bit pattern and a destination address bit pattern that are processed by a task processor in accordance with a data tree. A first bank of registers is utilized to load an instruction to be executed by the task processor at nodes of the data tree in accordance with the source address bit pattern. A second bank of registers is utilized for loading an instruction to be executed by the task processor at nodes of the data tree in accordance with the destination address bit pattern. A task scheduler enables the first bank of registers to transfer an instruction loaded therein for processing by the task processor only during even time cycles and for enabling the second bank of registers to transfer an instruction loaded therein for processing by the task processor only during odd time cycles.
