A network is disclosed that includes a first tier of forwarding agents connected to a first tier of network devices. A second tier of forwarding agents is connected to a second tier of network devices. A service manager is configured to receive a packet from one of the forwarding agents; determine the tier of the forwarding agent; and send an instruction to the forwarding agent directing the forwarding agent to forward the packet to a network device connected to the tier of forwarding agents that includes the forwarding agent.

Systems and methods for creating and sharing tasks over one or more networks are disclosed. 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.

Dynamic policy systems and methods for implementing network management of a network include pre-calculating management policies for the network, in an off-line manner, based on past observed network load taking into consideration seasonality of network load, forecasts of the network load, and planned events on the network load; selecting a policy from the pre-calculated management policies, to manage the network in an on-line manner, wherein the selecting is either time-based or performance-based; and performing network management functions in the network utilizing the selected policy.

A multi-layered network for transporting data comprises a first network layer that provides a first session topology, and a second network layer that provides a second session topology. The second network layer uses the first network layer to transport data. In one embodiment of the invention, the data sent by the second layer is real-time audio data, such as voice. Each session topology may be either peer-to-peer or client / server. The first and second layers may have different topologies and / or different session hosts. A deterministic algorithm is provided whereby a new session host is selected when the current host leaves the session.

A communications network has multiple resource-allocation layers and incorporates a management structure for allocating resources to allocate resources requested by a first layer of said layers from a second of said layers. At a first layer, the management structure provides an indication to a second layer of the required resources that are to be allocated from the second layer. The second layer automatically offers the required resource together with a condition for use of those resources. This condition includes a notional price factor which is dependent on current demand. Under the control of the manager, the first layer determines if the condition for use of the offered resources is acceptable and, if so, automatically accepts the offered resources from the second layer. In a preferred embodiment, ingress to an underlying multi-wavelength transport layer of the network is controlled via a virtual port which allocates traffic to real ports one for each wavelength supported by the transport layer.

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.

Each node of a telecommunications network determines interface point connection type attributes available for each signal type supported by the node. Each signal type represents a different connection routing layer within the telecommunications network. Adaptation costs involved in traversing from one connection routing layer to another connection routing layer in the node are calculated. The connection type attributes and adaptation costs are included in a link state advertisement broadcasted by each node in the telecommunications network. A route calculation is performed for a desired signal to determine a route through the telecommunications network for the signal. The route calculation takes into account the various connection type attributes, availability, and adaptation costs in determining the shortest route for the signal through the telecommunications network.
