Methods and systems for providing a logical network layer for delivery of input/output data

摘要

A method for routing input/output (10) data in a telecommunication system including a network node having a plurality of first integrated circuit (IC) cards, a plurality of second IC cards and a switching fabric, each second IC card connected to a corresponding first IC card in a respective slot of the network node xs described. The method involves receiving the IO data at an external port of any of the plurality of first or second IC cards. When packets of the IO data are received at an external port of a given second IC card, the given second IC card performs a packet classification of the packets to at least in part determine a destination for the packets. A further step of the method includes delivering the packets to a first or second IC card destination according to the packet classification performed by the given second IC card via a logical network layer existing on the first and second IC cards and the switching fabric. A particular implementation includes use in an Advanced Telecommunication Computing Architecture (ATCA) system.

1. A method for routing input/output (IO) data in a telecommunication system, the system comprising a network node comprising a plurality of first integrated circuit (IC) cards, a plurality of second IC cards and a switching fabric, each IC card of the plurality of second IC cards connected directly to an IC card of the plurality of first IC cards, each IC card of the plurality of first IC cards connected in a respective slot of the network node, the method comprising:
receiving the IO data at an external port of any of the plurality of first or second IC cards; when packets of the IO data are received at an external port of any of the plurality of second IC cards:
upon receipt of the packets by a given one of the plurality of second IC cards, the given one of the plurality of second IC cards performing a packet classification of the packets to at least in part determine a destination for the packets;delivering the packets to one of the plurality of first or second IC cards identified as a destination according to the packet classification performed by the given one of the plurality of second IC cards via a logical network layer existing on the plurality of first and second IC cards and the switching fabric, wherein the logical network layer includes a network device on each IC card of the plurality of first and second IC cards configured to perform packet classification and deliver the packets of the IO data to a destination.
