A method for displaying network performance information by selecting an aggregated end-to-end connection profile, and then displaying network performance information corresponding to the aggregated end-to-end connection profile. The network performance information corresponding to the aggregated end-to-end connection profile is retrieved from a local storage unit or a remote storage unit. The aggregated end-to-end connection profile is corresponding to an aggregated end-to-end connection comprising a plurality of end-to-end connections. In one embodiment, identities of all WAN interfaces corresponding to the aggregated end-to-end connection are displayed. Alternatively, identities of a plurality of WAN interfaces corresponding to the aggregated end-to-end connection are displayed, where the plurality of WAN interfaces are selected according to a policy or a user's selection. Furthermore, a message may be displayed for helping the user to select end-to-end connections for transmitting and receiving data packets based on the network performance information.
