Abstract: In a network device, unidirectional port aggregation can be used by aggregating corresponding ports that represent a single underlay next hop. A common layer 2 address (e.g., Media Access Control (MAC) address) can be shared across aggregated destination network devices to allow these network devices to accept traffic forwarded over the unidirectional multi-destination bond port. Port aggregations (e.g., “bonds”, “trunks”, etc.) are controlled by dynamic route updates propagating through a network of devices. Dynamic route updates can be implemented as part of routing protocols. The route updates can be interpreted by the network switches as including a port aggregation signal. Policy may be applied to these route updates to adjust the behavior of the port aggregation mechanism. The resulting port aggregation is installed in the forwarding table of network devices so that the corresponding prefixes resolve to the underlay next hop representing the aggregated port.

Abstract: Systems and methods are disclosed for generating synthetic representations of a network and performing path computations using the synthetic representations. A model of the network is created including different representations for different regions of the network based on the network mesh patterns (e.g., a sparse mesh representation, a Clos mesh representation, and a flat mesh representation). The generated representations include synthetic, aggregated nodes and/or links in the represented region that are determined based on different processes according to the type of mesh in the region. Path computations are performed for each representation (e.g., in parallel), then joined to form end-to-end paths between a source and a destination. The computed paths may be used to select a path for routing data through the network.

Abstract: A method for managing one or more class levels of service between a communication network and one or more other networks, including retrieving network information of network devices in the communication network; generating a customizable traffic engineering database based on the retrieved network information; receiving user input of path computation parameters; generating path information corresponding to optimal paths for a subset of the network devices; validating the generated path information; generating path configuration information based on the validated path information; transmitting the path configuration information to one or more of the network devices; generating an external service model comprising plural exit points for connecting to points of presence of the communication network corresponding to the path configuration information; and interconnecting the communication network with the one or more other networks on the one or more class levels of service through the plural exit points.
