摘要:
Additional bandwidth is provisioned to layer 2/3 networks by initially provisioning optical wavelength channels to meet incremental needs for additional capacity. When bandwidth requirements grow large enough, a wavelength-sized channel is provisioned to meet the bandwidth needs, and the previously provisioned optical wavelength channels are freed up to be reused for additional growth. The optical wavelength channels may be channelized VLANs mapped to resizable optical channel data units such as ODUflex units.

摘要:
A method and apparatus for optimally routing a data packet through multiple autonomous networks. A data packet received at an ingress node of a first autonomous network is routed to an egress node of a second autonomous network by selecting an optimal route based on the lowest latency using internal gateway protocol (IGP) routing information of the first and second autonomous networks, which is distributed to nodes of the first and second autonomous network. The data packet is then transmitted along the selected optimal route.
