In one embodiment, a system comprises a message retrieval module configured to retrieve electronic messages and parse them into a plurality of tasks. The system can also include a task creation module configured to process the message to identify task information and one or more task recipients. The task creation module can also be configured to create a task based on the identified task information. A task notification module can be configured to notify the one or more task recipients about the created task. The system may also include a multi-layer network management module configured to organize the tasks and task participants into multiple networks and clouds and into a federation of clouds. The system can also include a task analytics module programmed to analyze the tasks performed by users of the system.

A multiple key, multiple tiered network security system, method and apparatus provides at least three levels of security. The first level of security includes physical (MAC) address authentication of a user device being attached to the network, such as a user device being attached to a port of a network access device. The second level includes authentication of the user of the user device, such as user authentication in accordance with the IEEE 802.1x standard. The third level includes dynamic assignment of a user policy to the port based on the identity of the user, wherein the user policy is used to selectively control access to the port. The user policy may identify or include an access control list (ACL) or MAC address filter. Also, the user policy is not dynamically assigned if insufficient system resources are available to do so. Failure to pass a lower security level results in a denial of access to subsequent levels of authentication.

A method for providing broadband communications over a multi-layered network having a plurality of Open System Interconnection (OSI) Reference Model layers functioning therein includes monitoring at least one OSI reference model layer functioning in the multi-layered network. A quality of service event is determined whether to have occurred in the multi-layered network. The quality of service event is determined to have occurred at a layer N in the OSI reference model. Network provisioning is changed at a layer less than N in response to the quality of service event, and a signal is provided when the network provisioning at the layer less than N has been changed. A system for providing broadband communications includes a multi-layered network, a network monitor, and a network controller. The multi-layered network has a plurality of Open System Interconnection (OSI) reference model layers functioning therein. The network monitor is coupled to the multi-layered network, and the network monitor is adapted to monitor at least one OSI reference model layer functioning in the multi-layered network, determine that a quality of service event has occurred in the multi-layer network, and determine that the quality of service event occurred at a layer N in the OSI reference model. The network controller is coupled to the multi-layered network, and the network monitor is adapted to respond to the quality of service event in the multi-layered network by changing the network provisioning at a layer less than N.

For use in a wireless network, a femtocell base station in communication with at least one first mobile station is provided. The femtocell base station is configured adjust a resource of the femtocell base station to mitigate interference at a second mobile station. In certain embodiments, the femtocell base station is configured to coordinate a handover of the at least one first mobile station from the femtocell base station to a neighboring base station. In certain embodiments, the femtocell base station is configured to transmit a message regarding the resource adjustment to the at least one first mobile station.

A method is provided for routing data packets across a multi-layer network which includes a plurality of nodes, a logical level provided with a plurality of logical links and a physical level provided with a plurality of physical links, each of the logical links corresponding to at least one of the physical links, the method comprising the steps of assigning a weight to each logical link with respect to a first critical constraint in the logical level, refining the weight assigned to each logical link with respect to a second critical constraint in the physical level and, based on the weights assigned to each link, computing a path at the logical level connecting a start node to an end node for the transport of the data packets.

A distributed multilayered network routing architecture comprises multiple layers including a controller layer comprising a controller, a control plane layer comprising one or more control plane subsystems, and a data plane layer comprising one or more data plane subsystems. A controller may be coupled to one or more control plane subsystems. A control plane subsystem may in turn be coupled to one or more data plane subsystems, which may include one or more software data plane subsystems and/or hardware data plane subsystems. In certain embodiments, the locations of the various subsystems of a distributed router can be distributed among various devices in the network.

In the Network Global Expectation Model, expectation values evaluated over the entire network are used as a multi-moment description of the required quantities of key network and network element (NE) resources and commensurate network costs. The Network Global Expectation Model naturally and analytically connects the global (network) and local (network element) views of the communication system, and thereby may be used as a tool to gain insight and very quickly provide approximate results for the preliminary evaluation and design of dynamic networks. Further, the Network Global Expectation Model may serve as a valuable guide in the areas of network element feature requirements, costs, sensitivity analyses, scaling performance, comparisons, product definition and application domains, and product and technology roadmapping. The network is arranged as a multiple tier network of nodes in order to apply the analysis methods of the Network Global Expectation Model. The analytical method is developed to include non-uniform demands on the network.

Techniques for providing connectivity fault management (CFM) for a multi-tiered network are described herein. In one embodiment, a link trace message (LTM) is received at a provider edge (PE) router and originated from a first Ethernet node and destined to a second Ethernet node, where the PE router interfaces an Ethernet and a multi-protocol label switching (MPLS) network. In response, the PE router initiates an MPLS trace session, including generating an MPLS trace message based on the LTM message to one or more MPLS nodes along a path between the first and second Ethernet nodes within the MPLS network. Subsequently, in response to one or more MPLS trace reply messages from the MPLS nodes of the MPLS network, the PE router generates a first link trace reply (LTR) message and sends the first LTR message to the first Ethernet node over the Ethernet. Other methods and apparatuses are also described.

Provided are methods and systems for distributing an asset to a multi-tiered network node. A pending notice is received from a distribution server. If the notice indicates that at least one asset is pending, i.e., awaiting deployment, an asset descriptor manifest is received from the distribution server. The asset descriptor manifest, which is stored in a memory on a node, identifies at least one asset to be deployed to the node and includes an offset associated with the asset identifier. A fragment, associated with the asset, is received and stored in the memory. The offset associated with the asset is marked with the end of the fragment and a second fragment, beginning at the offset, is received. Additional fragments are received, and the offset updated, until the entire asset is deployed to the node. Alternately, the entire asset or multiple assets are received in the first fragment.
