The invention is embodied in a gigabit Ethernet adapter. A system according to the invention provides a compact hardware solution to handling high network communication speeds. In addition, the invention adapts to multiple communication protocols via a modular construction and design.

Gigabit ethernet adapter supporting the iscsi and ipsec protocols

A financial transaction processing system ( 10 ) enables processing transactions from various types of card activated terminal devices ( 12 ) which communicate using a variety of electronic message formats. The transaction processing system may operate to authorize transactions internally using information stored in a relational database ( 32 ) or may communicate with external authorization systems ( 18 ). The transaction processing system includes among its software components message gateway routers (MGRs) ( 24, 164 ) which operate using information stored in the relational database to convert messages from a variety of external message formats used by the external devices and authorization systems, to a common internal message format used within the system. The system further uses database information to internally route messages to message processing programs (MPPs) ( 108, 138 ) which process messages and generate messages to the external devices and authorization systems. The MGR also converts the outgoing messages from the internal message format to the external message formats which can be interpreted by the external devices and systems to which the messages are directed.

Financial transaction processing system and method

A multiple network protocol encoder/decoder comprising a network protocol layer (101), data handler (102), O.S. State machine (104), and memory manager (103) state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine (101) which decodes network protocols such as TCP, IP, user Data Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler (102) which consists of data state machines (104) that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML). Each data state machine (104) reacts accordingly to the pertinent data, and any data that are required by more than one data state machine (104) is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location (206) with a pointer designating such data; thereby ensuring minimal memory usage. Resulting display data are immediately passed to a display controller (205). Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

Multiple network protocol encoder/decoder and data processor

An apparatus for decoding and encoding network protocols and processing data, consists of a network stack (101) for receiving and transmitting packets and for encoding and decoding the packets, and a plurality of dedicated hardwired logic protocol modules (102, 103 and 104), each being optimized for a spesific network protocol, wherein the protocol modules (102, 103 and 104) execute in parallel.

Gigabit Ethernet adapter

An Internet client communicates with an Internet server such as an HTTP server or SMTP server through a TCP streaming socket on the Internet device with the Internet client. The TCP streaming sockets can be established through an Internet ready command line interface. The Internet ready command line interface includes “IR” commands that can establish, resume, release and terminate TCP sockets.

An improved network timer for use in a network node, preferably a reliable mode network employing IPX/SPX data packets on workstations or computer. A method and apparatus is disclosed for use by a workstation node whereby a plurality of data packet timers may be supported and set, triggered and deleted in a maximum of K operations or time increments, where K is a constant and not a function of N.

PROBLEM TO BE SOLVED: To set a timer in a system without making long the time needed to set and reset the timer by traversing a cell in a non-free state which is related to a time storage entry and implementing a function which is related to the time storage entry SOLUTION: Time storage entries 60 and 65 in a link list 50 are related to a timer for a specific data packet After the time storage entries 60 and 65 which have expired are traversed, the time storage entries 60 and 65 are removed from the link list 50 After time storage entries 60 and 65 like those are all removed from cells 1 and 6 in a specific non-free state, an array entry related to the cells 1 and 6 in the non-free state is removed from a double link list 50 and an arbitrary memory which relates to an arbitrary data structure is reallocated
