摘要:
A system that incorporates teachings of the present disclosure may include, for example, a network policy manager having a controller element to provision one or more network elements in a communication system with at least one base policy template and at least one atomic policy template retrieved from one or more base policy templates and a plurality of atomic policy templates according to a service order of a subscriber. At least one base policy template can correspond to an operating baseline of the one or more network elements, while at least one atomic policy template can correspond to one among a plurality of service configurations of the one or more network elements. Additional embodiments are disclosed.
摘要:
A method and apparatus for supporting an asymmetric transport network is disclosed. An apparatus that incorporates teachings of the present disclosure may include, for example, a network element having a number of bidirectional switching cards each logically reconfigured as at least one among ingress and egress switching elements for transporting asymmetric unidirectional packet traffic. Additional embodiments are disclosed.
摘要:
In an embodiment, a method of allocating media streams includes measuring real-time port usage data related to each of a plurality of physical ports associated with a link aggregation group. The method further includes selecting at least one, but not all, of the plurality of physical ports based on the real-time port usage data and sending a media stream to a network via the physical port.
摘要:
Methods for automating membership discovery in a distributed computer network are presented. A particular method includes establishing a Multi-Protocol Label Switching (MPLS) tunnel and Targeted Label Distribution Protocol (LDP) signaling channel between a first Provider Edge (PE) device and a plurality of PE devices. A first Virtual Private LAN Service (VPLS) site is added to a Multi-Tenant Unit (MTU) device associated with the first PE device. A first LDP Label Mapping Message is sent to the first PE device from the MTU device. The first LDP Label Mapping Message is broadcast to the plurality of PE devices from the first PE device. A second LDP Label Mapping Message is sent to the MTU device from the first PE device to establish a virtual circuit label switch path between the MTU device and the first PE device. A second VPLS site is added to the MTU device without sending an associated LDP Label Mapping Message to the first PE device. A respective one VPLS site of the first VPLS site or the second VPLS site is deleted using a configuration command.
摘要:
A computer-readable storage medium (102) is provided for managing end-to-end QoS (Quality of Service) policies in a communication network (100). The storage medium includes computer instructions for establishing (302) a plurality of QoS domains (108) between a plurality of packet switching technologies (102, 106. 110) operating with disparate QoS policies, each QoS domain having an ingress and egress boundary, remapping (303) a QoS policy of each packet exchanged between the ingress boundaries of the plurality of QoS domains, and restoring (309) the QoS policy of each packet exchanged between the egress boundaries of the plurality of QoS domains.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, a PE-ASBR (Provider Edge-Autonomous System Boundary Routers) having a controller to receive new routing information without an attribute of origin, insert a site of origin of the PE-ASBR into the new routing information if the PE-ASBR is dual-homed to another MPLS-VPN cluster, and broadcast to other network elements the new routing information with the site of origin of the PE-ASBR. Additional embodiments are disclosed.
