Windows Vista includes a specialized QoS API called qWave (Quality Windows Audio/Video Experience), [7] which is a pre-configured quality of service module for time dependent multimedia data, such as audio or video streams. qWave uses different packet priority schemes for real-time flows (such as multimedia packets) and best-effort flows (such ...
SMLT provides enhanced resiliency with sub-second failover and sub-second recovery for all speed trunks while operating transparently to end-devices. Multi-chassis link aggregation group provides similar features in a vendor-nonspecific manner. To the connected device, the connection appears as a normal link aggregated trunk.
Keepalive or keep-alive may also refer to: HTTP keep-alive, using a single TCP connection to send and receive multiple HTTP requests/responses; Keep-alive electrode, of a krytron; Keepalive, a sculpture in Germany by Aram Bartholl
