Abstract: Devices, systems, methods, and processes for dynamically generating indications regarding the sustainability of one or more virtual meeting options is described herein. Virtual meetings can have participants join from all over the world and from very different computing devices which can each be powered by different power source types. When selecting a time for a virtual meeting between a number of participants, a large number of combinations may occur with each option having a different level of sustainability associated with it. However, by accessing historical data, sustainability data, participant data and by gathering various virtual meeting settings, a plurality of options can be presented having one or more indications associated with a particular category of sustainability. A sustainability threshold may be determined and utilized to categorize virtual meeting options as well.

Abstract: An efficient method to handle fragmented packets in multi-node all-active clusters. In one particular embodiment, a method includes receiving an initial fragment packet at a node in a cluster, creating a secondary flow table, linking the secondary flow table to a primary flow table, determining the primary flow owner of the initial fragment packet, and transmitting initial and succeeding fragment packets out of the cluster through, if possible, the primary flow owner.

Abstract: Techniques for load balancing encrypted traffic based on security parameter index (SPI) values of packet headers and sets of 5-tuple values of the packet headers are described herein. Additionally, techniques for including quality of service (QoS)-type information in SPI value fields of packet headers are also described herein. The QoS-type information may indicate a particular traffic class according to which the packet is to be handled. Further, techniques for pre-configuring a backend host such that encrypted traffic may be migrated to the backend host from another backend host without causing temporary service disruptions are also described herein.

Abstract: In one embodiment, quasi-Output Queue behavior of a packet switching device is achieved using virtual output queue (VOQ) ordering independently determined for each particular output queue (OQ), including using maintained latency information of the VOQs of the particular OQ. In one embodiment, all packets from all VOQs with a same port-priority destination experience similar latency within specific time-window, which is similar to the packet service provided by an Output Queue switch architecture. In one embodiment, all input ports that send traffic to same output port-priority receive bandwidth which is proportional to their bandwidth demand divided by total bandwidth. Prior approaches that emulate the performance of an OQ switch architecture require complex and time-consuming scheduling determinations and do not scale. Independently determining the order for sending packets from the VOQs associated with each particular OQ provides a scalable and implementable system with quasi-Output Queue behavior.

Abstract: A combinational circuit (e.g., multiplexer or demultiplexer) comprises a sub-circuit that comprises first and second current paths from an input of the combinational circuit to an output of the combinational circuit, such that substantially all input current at the input of the combinational circuit is conducted by the sub-circuit via the first and second current paths to the output of the combinational circuit. The first current path comprises a first inductor and a first switch; and the second current path comprises a second inductor and a second switch. The first inductor is part of an output LC transmission line of the sub-circuit; the second inductor is part of an input LC transmission line of the sub-circuit; and the first and second inductors are sized such that parasitic capacitances of the first and second switches are substantially absorbed by the input and output LC transmission lines.

Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address, the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first MAC address.
