摘要： Methods, systems, and computer program products for multipath Shortest-Path-First (SPF) computations and distance-based interface selection for VoIP traffic are disclosed. According to one method, a multi-path router instance associated with a plurality of network interfaces in a source IP device is provided. A cost is assigned to each of a plurality of internal segments between the multi-path router instance and the network interfaces associated with the multi-path router instance. An aggregate cost is calculated for each of a plurality of traffic paths originating at the multi-path router instance in the source IP device and extending through each of the network interfaces associated with the multi-path router instance to a destination IP device in the network. A list of IP paths is generated, and the paths in the list are ranked based on the calculated cost. Traffic is sent from the source IP device over at least one of the paths in the list. The path costs and rankings are updated in response to segment cost changes.

According to one aspect, the subject matter described herein includes a method for oversubscription of wireless media gateway resources. The method includes defining at least one per-resource oversubscription factor for wireless media gateway resources required by at least one wireless network connection. The wireless media gateway resources are provisioned for the at least one wireless network connection using the at least one per-resource oversubscription factor. Allocating the wireless media gateway resources to the at least one wireless connection network includes oversubscribing the wireless media gateway resources by an amount based on the at least one per-resource oversubscription factor to increase utilization of the wireless media gateway resources by increasing the number of wireless network connections that the wireless media gateway is capable of serving.
