Abstract: One aspect can provide a system and method for configuring a plurality of branch gateway (BGW) devices coupled to a virtual private network concentrator (VPNC). The VPNC negotiates with a respective BGW device a transmission-bandwidth contract; receives, from the BGW device, a request for additional transmission bandwidth; analyzes traffic patterns to identify one or more BGW devices with unused bandwidth; allocates the requested additional transmission bandwidth to the respective BGW device by reducing transmission bandwidth allocated to the identified one or more BGW devices; and transmits contract-update notifications to the BGW devices to allow each BGW device to update a corresponding transmission-bandwidth contract, which comprises increasing the upper bandwidth limit at the respective BGW device while reducing the upper bandwidth limit at the identified BGW devices. In response to expiration of a timer, the VPNC revokes the additional transmission bandwidth allocated to the respective branch gateway device.
