  • Patent number: 9397924
    Abstract: Systems and methods are described that manage routing information in an IP network using extensible indexing and use the indexing to control the network. The indexing and associated controls apply to any router within the routing domain.
    Type: Grant

  • Patent number: 9042727
    Abstract: 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.

  • Patent number: 8248951
    Abstract: Methods and apparatus to manage bypass paths in an Internet protocol (IP) network are disclosed. An example method disclosed herein includes receiving IP traffic at an aggregation router and measuring a bandwidth value of the IP traffic forwarded from the aggregation router to an IP router at a starting node. The example method also includes establishing a first non-routed bypass path between a switch at the starting node and a first switch at a first destination node when a measured traffic throughput value of the IP router at the starting node exceeds a first threshold value, and sending the IP traffic from the aggregation router via the bypass path.

  • Patent number: 8023821
    Abstract: This is a method for use in architecting low cost networks using a thin optical transport layer. A long reach hot pluggable interface is inserted onto an electrical switch resulting in a standardization of the optical layer. Standardized parts like the long reach hot pluggable interfaces and standard control planes form the logic that connects components of the low cost optical layer. After the components are in place, provisioning is done at end points only. This ensures an automatic and fast turn-up capacity without the need to visit intermediate sites in the network.

  • Patent number: 8018941
    Abstract: Systems and methods are described that disassociate Internet route table growth from the ability of a router to maintain service. A network operator may base their network design using predetermined devices implemented from the beginning of service as constrained routers. This eliminates concern that these devices would require upgrade or replacement in the future.
