摘要： This disclosure describes a method and apparatus for signaling the phase and frequency of OTN and Constant Bit Rate (CBR) clients in an OTN network. The principles discussed are applicable when multiple stages of OTN multiplexing and demultiplexing are utilized. They are also applicable for use with the Generic Mapping Procedure (GMP) and Asynchronous Mapping Procedure (AMP). A method to use the phase and frequency of an ODUk/ODUflex to adjust a local reference clock to enable the recovery of the phase and frequency of a CBR client demapped from the ODUk/ODUflex is described.

摘要： A data network wherein network links have an assigned service weight and a restoration weight that are used as factors for respectively determining an optimum primary data path and a back-up data path through the network. The restoration path is used in the event of a failure of the primary service path and a Dijkstra or similar algorithm may be used for determining these paths. Service weights may be assigned to the links to prioritize finding the shortest possible path, whereas restoration weights may be assigned to the links to find a path with the maximum available capacity.

摘要： The present invention leverages an existing content delivery network infrastructure to provide a system that enhances performance for any application that uses the Internet Protocol (IP) as its underlying transport mechanism. An overlay network comprises a set of edge nodes, intermediate nodes, and gateway nodes. This network provides optimized routing of IP packets. Internet application users can use the overlay to obtain improved performance during normal network conditions, to obtain or maintain good performance where normal default BGP routing would otherwise force the user over congested or poorly performing paths, or to enable the user to maintain communications to a target server application even during network outages.

摘要： The invention includes a method and apparatus for transporting a Multiprotocol Label Switching (MPLS) frame over a communication link. In the egress direction of communication, a method includes encapsulating the MPLS frame within a Generic Framing Procedure (GFP) frame, forming an augmented frame by adding at least one Ethernet Media Access Control (MAC) header field to the GFP frame, and transmitting the augmented frame over the communication link. In the ingress direction of communication, a method includes receiving an augmented frame over a communication link, removing at least one Ethernet Media Access Control (MAC) header field from the augmented frame to extract thereby a Generic Framing Procedure (GFP) frame, and decapsulating the MPLS frame from within the GFP frame.
