Multi-protocol gateway

Abstract

A connection gateway between a first device and a second device, implemented as an instructionless circuit, comprising: a first connection port configured to extract payload data from an incoming frame, extract a routing identifier from said incoming frame; a routing engine connecting said first connection port and a second connection port, configured to determine, from said routing identifier, said second connection port as the destination port, transmit said payload data with said routing identifier; and said second connection port configured to determine, from said identifier, transmit frame parameters, insert said payload data into a transmit frame according to said parameters. Said management module and said routing engine operate at a layer higher than a transport layer.Without abbreviation.

Claims

Demands

1. A connection gateway (301) between a first communicating device (311) and a second communicating device (312, 302), in a communication between said communicating devices (301, 311), said gateway being implemented in the form of an instructionless circuit and comprising: - a first data frame management module (306) configured to receive data frames from said first communicating device (311), and to • extract (403) the payload from a received incoming frame, • extract (404) a routing identifier from said incoming frame, - a routing engine (304) linking said first data frame management module (306) and a second data frame management module (307, 305) configured to transmit data frames from said second communicating device (312, 302), and for • determine (406), from said routing identification, said second data frame management module (307, 305) as the destination data frame management module, • transmit (407) said payload with said routing identification, and - said second data frame management module (307, 305), configured for • determine (409, 413), from said identification, the transmit frame parameters, • insert (410, 414) said payload into a transmit frame according to said parameters, in which said data frame management module and said routing engine intervene on said input and output frames at a layer higher than a transport layer of said communication.

2. Gateway according to claim 1, wherein said second data frame management module comprises: - a plurality of physical connection ports to analog and / or digital type signals (702, 806) for connection with said second communicating device (303), and - means for distributing said payload over said plurality of physical connection ports.

3. Gateway according to any one of the preceding claims, wherein said first data frame management module comprises: - a plurality of physical connection ports from analog and / or digital type signals for connection with said first communicating device, and - means for associating ports of said plurality of physical connection ports with respective sub-parts of said payload.

4. Gateway according to any one of the preceding claims, wherein at least one of said first and second data frame management modules is configured for connection (308, 603) to a processor bus (903) configured for direct connection to an external processor (900), said data frame management module being configured to interface with a connection driver (601, 901) of software (600, 902) via application connection interfaces (602).

5. Gateway according to any one of the preceding claims, wherein the first and second data frame management modules operate according to two different protocols.

6. Gateway according to any one of the preceding claims, comprising at least three data frame management modules and configured to transfer a payload of the same frame from an input data frame management module to two output data frame management modules.

7. Gateway according to any one of the preceding claims, wherein at least one data frame management module operates according to one of the following protocols: Ethernet CAN, A664, A825, A429, RS422, ISOSPI, 1553, Modbus.

8. Gateway according to any one of the preceding claims implemented in an integrated circuit of type among ASIC, FPGA.

9. System comprising: - a gateway according to one of the preceding claims, and - at least two communicating devices connected to said gateway on data frame management modules.

10. System according to claim 9, further comprising a control unit (900) connected to the gateway via a processor port via a processor bus.

11. System according to any one of claims 9 and 10, further comprising an electronic card having external electronic blocks for connecting said communicating devices to the data frame management modules of said gateway.
