Abstract: An approach is provided for auto-bandwidth adjustment of allocated bandwidth for a traffic tunnel over a network. A determination is made regarding a traffic load over the tunnel, where the tunnel meters traffic in accordance with the bandwidth allocation. A determination is made regarding whether the traffic load triggers an adjustment threshold, where the adjustment threshold is set to provide a desired headroom below the bandwidth allocation. And the bandwidth allocation is adjusted when the adjustment threshold is triggered to provide the desired headroom between the adjusted bandwidth allocation and the traffic load.

Abstract: A system and method may include receiving a new flow request, the new flow request for requesting provisioning of a flow between a computer and the server, identifying a path of one or more network elements between the computer and the server, and determining whether provisioning the flow between the computer and the server violates a constraint. The system and method may further include updating an oversubscription factor and available bandwidth for an interface of each of the one or more network elements in the event the constraint is not violated, and determining whether a second path exists between the computer and the server in the event the constraint is violated.

Abstract: A method may include forming a first path from a first node to a second node and transmitting data via the first path. The method also includes measuring a performance parameter associated with transmitting data via the first path and determining whether the measured performance parameter meet a required performance parameter. The method also includes sending a notification to a customer associated with the first path when the measured performance parameter does not meet the required performance parameter, where the notification indicates that the first path is unavailable.

Abstract: A method may include forming a primary label switching path (LSP) from a first node to a second node, where the primary LSP has a path metric that is less than a predetermined value. The method may also include detecting a failure in the primary LSP and identifying a second path from the first node to the second node that has a path metric that is less than the predetermined value. The method may further include routing data via the second path in response to the failure in the primary LSP.

Abstract: A device stores a link aggregation group (LAG) media access control (MAC) address, and assigns the LAG MAC address to two or more links in the device to define a LAG. The LAG MAC address is distinct from physical MAC addresses of the links in the LAG.

Abstract: A device enables a disabled timer state for a link aggregation group (LAG) link if a disabled timer condition is determined for the LAG link, and enables a disabled state for the LAG link if a disabled condition is determined for the LAG link in the disabled timer state.

Abstract: A device detects a signal condition for a link aggregation group (LAG) link, compares the detected signal condition to a signal threshold range, and enables one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range.

Abstract: A network device controls the flow of traffic in a network, such as an Ethernet-based network. The network device detects congestion in the network and identifies at least one upstream device to which to send a flow control message, where the upstream device is a device that is transmitting above a predetermined level. The network device then transmits the flow control message to the identified upstream device. The flow control message instructs the identified upstream device to slow down transmissions to the network device.
