摘要: The present invention describes a 'companion' to an existing router that is multi-homed transit Autonomous Systems (TASs) plurality of destination (DASs). mechanism includes path testing process conducts local traffic analysis outgoing packets transmitted from the set IP addresses across different DASs may be selected by operator via configuration file or suitable interface. To perform particular link and transmit AS, temporarily inserts into more specific overriding test routes which send ping (308). Following (310-312), are withdrawn (314). data collected this scanning then supplied evaluation (306), decision algorithm for evaluating quality each TAS/DAS pair. A whose below configurable threshold candidate re-routing. selection (326) either recommend (330)s or, if enabled, executes changes (332), e.g., logging entering new policy configuration. This has effect telling reevaluate all heard TAS in view policy. testing, when enabled processes operate autonomously automated fashion control outbound links.
