摘要： A method and/or network system is able to perform an in-service software upgrade (“ISSU”) using virtualization technology while ongoing network service is maintained. After receipt of an upgrade signal such as a command of software upgrade, a new or second virtual machine (“VM”) is created in response to the upgrade signal. After downloading the new version of program to the second VM while maintaining the first version of program running on the first VM, the process for providing network management begins to migrate from the first version of program to the new version of program. The process simultaneously facilitates ISSU for a data-path module such as a line card to convert from the previous version of software to the new version of the software.

摘要： A procedure for evaluating a network, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure includes aggregating packet information from one or more sources in a network, and executing a correlation algorithm to determine traffic flow information based on the packet information. The aggregating includes obtaining information from a header of a packet being communicated in the network, in one example embodiment. In another example, the executing includes tracing a traffic flow from a source node to a destination node, and the tracing includes determining, based on the packet information, each link by which the traffic flow is communicated from the source node to the destination node.

摘要： Source-synchronous communications between networked devices can be hindered by differing clock rates and data interface formats among the devices. By implementing a plurality of clock converters, a data interface format of a transmitting device is converted to a data interface format compatible with a receiving device. The clock converters provide a clock signal based on the source-synchronous data clock, and having a phase controlled with respect to an associated data signal. As a result, data exchange between devices operating at different clock rates is made possible.

摘要： A procedure, apparatus, system, and medium for transferring traffic across a packet network. In the procedure, a network element bundles a plurality of common (Synchronous Transport Signal) STS-Nc services included in a virtual concatenation group. The network element then transfers the traffic in accordance with the bundled plurality of STS-Nc services. In one example embodiment herein, the plurality of STS-Nc services are STS-1 services, and each bundle of STS-1 services is aligned to a timeslot boundary of an STS-3c service.

摘要： In a telecommunications/data network, it is common to have multiple recovery domains each employing its own technique for recovering a fault that may be different from a technique employed by another domain. Permitting multiple recovery domains to recover a fault without coordination among the domains can result in adverse interactions, such as rapid and repeated changes in the actions taken or “flapping,” and repeated hits to traffic. A method and corresponding apparatus for coordinating fault recovery in a network, according to an embodiment of the present invention, notifies a first recovery domain that a second recovery domain is or is not taking action to recover a fault in the network. Coordinating the recovery efforts of the first and second recovery domains reduces fault recovery time and allows concurrent actions to be taken.

摘要： A device having circuit bundles and a method of configuring the network device to provide resiliency and protection for network circuits. A circuit bundle provides the ability to group multiple circuits of the same type for resiliency/protection. There is an active virtual circuit that is selected based on a user configured priority value defining priority for carrying circuit traffic. When the active virtual circuit fails, alternative virtual circuits are selected to carry the circuit traffic, again based on user configured priority. Virtual circuits included in the circuit bundle can have different destinations, and include at least multipoint virtual circuits.

摘要： Embodiments including methods, systems, and apparatuses for distributing, processing, and reacting to path information distributed via a service-agnostic packet fabric for the purpose of enabling path selection are disclosed. By configuring two ingress line cards to send path quality words to each other via the switch fabric, compare the path quality words, and determine whether to transmit traffic to an egress line card via the switch fabric based on the comparison of the path quality words, the embodiments enable a central switch fabric to be unaware of the paths that it carries, and enable both ingress and egress bandwidth of the switch fabric to be sized according to the facilities for which it is terminating. The switch fabric does not need to support working and protection paths simultaneously in some embodiments, allowing it to be scaled appropriately to termination facilities.
