METHODS, SYSTEMS, AND APPARATUSES FOR ENHANCED PARALLELISM OF TIME-TRIGGERED ETHERNET TRAFFIC USING INTERFERENCE-COGNIZANT NETWORK SCHEDULING

Abstract:

Methods, systems, and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by pre-processing, by a scheduling algorithm implemented by a Network Scheduling Tool (NST), VL information prior to initiating a scheduling procedure by, detecting VL information associated with VLs that having common physical resources that include a common direction of a switching port or an egress end system port; and storing the VL information associated with the set of VLs for retrieval by the NST to parse a VL list for scheduling to determine one or more conflicting VLs in functionalities with a VL that is to be scheduled by a first pass that attempts favoring scheduling a VL into a bin when previously scheduled VLs fail to exhibit conflicts; and a second pass that attempts to resolve at least one conflict exhibited in the scheduling procedure by offsetting a transmit time.
