  • Publication number: 20240121158
    Abstract: Apparatuses, systems, and methods are provided for scalable networking systems. An example system includes a plurality of core switches and a first stage patch panel associated with operation of a first set of network ports. In an operational configuration in which the first stage patch panel is coupled with the plurality of core switches, the first stage patch panel is configured to operatively couple the first set of network ports and a first portion of the plurality of core switches such that signals may pass therebetween. Furthermore, the first stage patch panel may preclude communication to a remaining portion of the plurality of core switches. The system may include a second stage patch panel associated with a second set of network ports that is operatively coupled with the plurality of core switches in the absence of the first stage patch panel so as to scale the networking system.

  • Publication number: 20240107206
    Abstract: A method for distributed allocation of data paths in an optical network (100) including optical switches (30, 32, 130) connected by optical links (44, 140), includes receiving a request for a data path for connecting a source node (10) and a destination node (20). In in response to the request, one or more queries are sent, the queries corresponding to one or more candidate optical circuits that connect the source node and the destination node, the queries requesting one or more processors (230) to configure the optical switches along the candidate optical circuits to reserve optical channels on the optical links of the candidate optical circuits for the requested data path. An optical circuit is identified from among the candidate optical circuits, in which all the optical channels for the requested data path have been reserved successfully. The requested data path is established over the identified optical circuit.

  • Publication number: 20240098104
    Abstract: Systems, computer program products, and methods are described herein for machine learning (ML) based network resilience and steering. An example system monitors data traffic across one or more network ports and determines a first data traffic pattern from the data traffic. The system further determines, via a ML subsystem, that the first data traffic pattern is indicative of a security threat to a first network port. In response to determining that the first data traffic pattern is indicative of the security threat to the first network port, the system further isolates the first network port from the one or more network ports.
