Modular network switch with peer-to-peer address mapping communication |
摘要 |
Modules of a network switch receive data transmissions from network stations via its I/O ports, each data transmission including an address of a source network station sending the transmission and an address of a destination station to receive the transmission. Each module receiving a data transmission either passes it on to a next module of the network switch via a ring bus or forwards it to the destination station when it is accessible via one of the module's own I/O ports. Each module includes an address translation unit mapping the network address of each station to the particular I/O port though which that network station communicates. The address translation unit updates its address-to-port mapping when a data transmission arrives at an I/O port from a source station having an unmapped or incorrectly mapped address, and then sends a mapping instruction to address translation units of all other switch modules via the ring bus telling them to similarly update their network address mappings.
