Abstract: Embodiments of a system with a first network device and at least first and second links connecting the first network device and one or more other network devices are disclosed. The first network device determines the costs of the first and the second links using the latencies of the first and the second links and factors that correspond to the bandwidths of the first and the second links.

Abstract: Embodiments of identifying a subnet address range from DNS information are disclosed.

Abstract: A videoconferencing system and method of automating access to a videoconferencing room is provided. The videoconferencing system includes a reservation controller for comparing remote identifying information and local identifying information and for receiving a deposit. A payment collector is in communication with the reservation controller for receiving the deposit from the reservation controller. An access controller is in communication with the payment collector and the reservation controller for allowing access to the videoconferencing room if the remote identifying information matches the local identifying information. The method includes the steps of receiving remote identifying information, receiving local identifying information, comparing the local identifying information to the remote identifying information, and electronically unlocking a door of the videoconferencing room if the local identifying information matches the remote identifying information.

Abstract: Embodiments of a system (110) with a first network device (110) and at least first and second links (122) connecting the first network device and one or more other network devices (110) are disclosed. The first network device determines the costs of the first and the second links using the latencies (132) of the first and the second links and factors (136) that correspond to the bandwidths (134) of the first and the second links.
