Assured Forwarding (AF), RFC 2597 and RFC 3260, providing some priority policies for aggregate flows. DiffServ traffic management mechanisms include: At edge routers of the DiffServ domain: single flows are analyzed operating classification (on the basis of the DSCP), marking, policing, and shaping functions. At core routers within a DiffServ domain: forwarding is based on differentiated PHBs; also buffering and scheduling are based on marking at edge routers. \u00a9 2013 Queuing Theory and Telecommunications: Networks and Applications \u2013 All rights reserved.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
