Definitions

  • the invention relates to a method of transporting information from a first network unit to a second network unit, the method comprising: providing the network units being adapted to communicate via the XGMII or Fibre Channel standard defining a simultaneous transfer of a number of words of information relating to data or control information, each network unit being adapted to determine whether information received relates to data or control information, the network units communicating via a transmission path, providing, in the first network unit, condition information relating to one of a number of conditions obtainable in the first network unit during normal operation, - transmitting, over the transmission path as control information, the condition information to the second network unit.
  • the communication path comprises a pair of PHYs receiving the information to be communicated on a physical medium (optical fibre, wires or over the air) and/or receiving the information communicated from the medium, and which are adapted to transmit and receive the information to and from the medium without amending any XGMII control information thereby.
  • the PHY's may add information into the XGMII data stream. This additional information is, though, removed by the receiving PHY before the actual XGMII data stream is regenerated.
  • the words defined to be simultaneously transmitted may constitute an XGMII Sequence Ordered_Set or Signal Ordered_Set.
  • Sequence Ordered_Sets SOS
  • SOS Sequence Ordered_Sets
  • Signal Ordered_Sets having a header of "5C hex”
  • 5C hex could be used in exactly the same manner.
  • Fig. 2 illustrates the structure of a preferred embodiment of an Ethernet packet preamble and the division thereof into the words for transmission on a XGMII interface.
  • the SOS is a specific type of column where the first lane (Lane 0) has a predetermined content defining a SOS.
  • the remainder of the column is, in practise, reserved but only two values (representing remote fault or local fault) are used/defined.
  • the high throughput l/O's 12, 22, and 24 are expanded to also illustrate Media Access Controllers 17 and XGMII Reconciliation Sub-layers 15.
  • the MAC's 17 define the overall protocol for the communication on the link 18, which is now illustrated as two PHY's communicating via an optical fibre, and the MAC's strip away the preamble information transmitted as part of a packet.
  • the RS's 15 are the ones introducing and stripping off the SOS'es and which will then provide any additional information provided therein - such as the present congestion information.

Abstract

L'invention concerne des informations transmises entre deux partenaires de liaison (10,20) en tant qu'ensembles ordonnés selon une séquence (Sequence Ordered_Sets) ou qu'ensembles ordonnés selon un signal (Signal Ordered_Sets) dans un canal de fibre (18) ou dans XGMII. De tels ensembles sont définis pour ne pas être amendés par l'intervention de PHY, et peuvent être transmis même si il n'y a pas d'autre trafic entre les partenaires de liaison. Ces informations transmises peuvent être des informations de congestion dans une situation dans laquelle il existe un fort trafic dans une direction entre les partenaires de liaison (10, 20) et peu ou pas de trafic dans l'autre direction.
