TIME SYNCHRONIZATION BETWEEN NODES OF A SWITCHED INTERCONNECT FABRIC

摘要

A data processing node includes a local clock, a slave port and a time synchronization module. The slave port enables the data processing node to be connected through a node interconnect structure to a parent node having time-based functionality thereof that is operating in accordance with a fabric time of the node interconnect structure. The time synchronization module is coupled to the local clock and the slave port. The time synchronization module is configured for engaging in a time synchronization message exchange sequence with a node connected to the slave port thereof to collect parent-centric time synchronization information and synchronizing operation of a central processing unit (CPU) structure of the data processing node with the fabric time using the parent-centric time synchronization information.

1. A data processing node, comprising:
a local clock; a slave port for enabling the data processing node to be connected through a node interconnect structure to a parent node having time-based functionality thereof that is operating in accordance with a fabric time of the node interconnect structure; and a time synchronization module coupled to the local clock and the slave port, wherein the time synchronization module is configured for engaging in a time synchronization message exchange sequence with a node connected to the slave port thereof to collect parent-centric time synchronization information and synchronizing one or more time-based functionality of the data processing node with the fabric time using the parent-centric time synchronization information.
