Abstract: Techniques are described herein for service chaining in fabric networks such that hardware resources can be preserved without service nodes needing additional capabilities. The techniques may include storing a first configuration associated with a first VRF instance of a service forwarding node that is connected to a first service of a service chain sequence. The first configuration may indicate an identifier and a type associated with a second service of the service chain sequence where traffic is to be sent after the first service. Additionally, the techniques may also include storing a second configuration associated with a second VRF instance of the service forwarding node that is connected to the second service. The second configuration may indicate that the second service is a last service of the service chain sequence. When traffic is received at the service forwarding node, the service forwarding node can determine whether the traffic is pre-service traffic or post-service traffic.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media to address bearer loss during inter-radio access technology (RAT) handovers. A method includes sending a create bearer request for establishing a service for the mobile device using a first connection; receiving a create bearer response message to setup a second connection for the mobile device to continue the service; and, in response to the create bearer response message, sending an update bearer request message to provide the mobile device with the QoS information associated with the second connection, the QoS information allowing the mobile device to verify an existing QoS flow to continue the service after the handover. In some cases, a user equipment (UE) may delete a mapping between a QoS information when a previous message does not include an evolved packet core (EPC) bearer indicator (EBI) that identifies QoS policies.

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.

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.
