Publication number: 20230198803Abstract: Techniques for uplink connectivity determination are disclosed. In an example, a Frame Link Module (FLM) in a frame, belonging to a group of frames connected in a ring network, may generate an uplink discovery packet. The FLM may determine, based on a Link Layer Discovery Protocol (LLDP) packet received by the standby uplink from a customer network accessing the ring that the standby uplink has a link to the customer network. The FLM may forward the uplink discovery packet to the standby uplink via a Peripheral Component Interconnect (PCI) interface. The FLM may send the uplink discovery packet to the customer network through the standby uplink directed to an owner FLM. The owner FLM may monitor receipt of the uplink discovery packet from the customer network through a current active uplink and on successful receipt may determine that the standby uplink and switches in the customer network are correctly configured.Type: ApplicationFiled: December 17, 2021Publication date: June 22, 2023Inventor: Christopher Murray

Publication number: 20220392666Abstract: A twisted pair data cable has an internal construction that introduces an additional lay length design variable and thus permits a greater range of lay scheme options. A four-pair data cable can comprise four twisted pairs and can be fabricated such that the twisted pairs are segregated into two groups that each comprise two twisted pairs. In addition to the individual conductor pair twists, each of the two groups of two twisted pairs can be twisted independently of one another, improving the cable's ability to reject both internal and alien crosstalk interference. The smaller circumferential distance of each group also allows each group to have a smaller minimum overall lay if desired, allowing for a greater range of design options when selecting a combination of individual pair and overall lay lengths that satisfy electrical specification requirements in terms of interference rejection, insertion loss, and propagation delay.Type: ApplicationFiled: June 3, 2021Publication date: December 8, 2022Inventors: Christopher Murray Sproule, Paul Richardson

Patent number: 11461198Abstract: A method and system are disclosed to enable an FLM designated as an owner, in a group of frames having redundant FLMs per frame, to ensure that an unresponsive “active” uplink is disabled, prior to allowing another uplink in the frame to become the active uplink. A group of frames, configured in a ring network topology, may only have a single uplink at a time. Otherwise, two or more concurrent active uplinks may cause a network loop that may result in total network failure (e.g., network crash). The disclosed method utilizes a coordination between an FLM owner on the ring and the neighbor FLM, in the same frame as the non-responsive FLM, to disable the active uplink, prior to transitioning to a new active uplink for the group of frames.Type: GrantFiled: April 7, 2021Date of Patent: October 4, 2022Assignee: Hewlett Packard Enterprise Development LPInventor: Christopher Murray

Patent number: 11171810Abstract: Techniques for detecting misconfiguration of an uplink or an external network device connected with the uplink is disclosed. In an aspect, a Frame Link Module (FLM) in a frame belonging to a group of frames connected in a ring network, may determine that an uplink of the FLM is configured in a management mode. The FLM may determine, based on a system description associated with a Link Layer Discovery Protocol (LLDP) packet, whether the uplink is connected to a network device in an external network. Based on Virtual Local Area Network (VLAN) traffic being dropped, it may be determined that VLAN configuration of one of the uplink and the network device is incompatible for operation in the management mode. The uplink with incompatible VLAN configuration or the uplink connected with a network switch having incompatible VLAN configuration may be removed from a group of uplinks available for selection as an active uplink for the frames.Type: GrantFiled: October 7, 2020Date of Patent: November 9, 2021Assignee: Hewlett Packard Enterprise Development LPInventor: Christopher Murray

Patent number: 11108623Abstract: Systems and methods address automated ring owner selection for a ring topology network. A new ring owner may be selected based on failure of a current ring owner. The new ring owner may assume a ring ownership role by a) detecting a missing Ownership Select Message (OSM); b) detecting missing Continuity Check Protocol (CCP) messages; and c) determining that the current ring owner is an adjacent network module connected via an external link of a management network. A signal fail (SF) condition may also be present. Upon detection of adequate role changing conditions, a new ring owner may assume a ring ownership role, transmit an OSM and possibly select a new active uplink.Type: GrantFiled: January 25, 2019Date of Patent: August 31, 2021Assignee: Hewlett Packard Enterprise Development LPInventor: Christopher Murray
