    Abstract: Systems and methods for network bandwidth, buffers and timing management using hybrid scheduling of traffic with different priorities and guarantees are provided. In certain embodiments, a method of managing network scheduling and configuration comprises, for each transmitting end station, reserving one exclusive buffer for each virtual link to be transmitted from the transmitting end station; for each receiving end station, reserving exclusive buffers for each virtual link to be received at the receiving end station; and for each switch, reserving a exclusive buffer for each virtual link to be received at an input port of the switch. The method further comprises determining if each respective transmitting end station, receiving end station, and switch has sufficient capability to support the reserved buffers; and reporting buffer infeasibility if each respective transmitting end station, receiving end station, and switch does not have sufficient capability to support the reserved buffers.

    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.

    Abstract: Methods, systems, and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by determining a subset of a group of bins allocated to TT traffic; restricting the subset bin groups to a specified harmonic subdivided pattern with a certain duration; allocating the subset of bin groups in accordance with bin group equated with a rate at least twice as high as a highest TT traffic rate available in the network to enable control of partitioned traffic by using a set of media reservations; checking whether a bin selected via a bin selection process for scheduling a TT Virtual Link (VL) is a valid TT bin, else proceeding to a subsequent bin until a valid TT bin is returned for the TT VL, and reserving using at least one media reservation for a TT VL to be scheduled by temporal partitioning at the restricted rate.

    Abstract: Systems and methods for interference cognizant network scheduling are provided. In certain embodiments, a method of scheduling communications in a network comprises identifying a bin of a global timeline for scheduling an unscheduled virtual link, wherein a bin is a segment of the timeline; identifying a pre-scheduled virtual link in the bin; and determining if the pre-scheduled and unscheduled virtual links share a port. In certain embodiments, if the unscheduled and pre-scheduled virtual links don't share a port, scheduling transmission of the unscheduled virtual link to overlap with the scheduled transmission of the pre-scheduled virtual link; and if the unscheduled and pre-scheduled virtual links share a port: determining a start time delay for the unscheduled virtual link based on the port; and scheduling transmission of the unscheduled virtual link in the bin based on the start time delay to overlap part of the scheduled transmission of the pre-scheduled virtual link.
