A network device includes computing resources for utilization by processes hosted by the network device and a computing resources manager. The computing resources manager automatically instantiate a new instance of a first process of the processes upon termination of the first process; makes a determination that the network device has entered an out of computing resources state; and in response to the determination: performs an action set to increase a quantity of the computing resources that are available for allocation to the processes.

System and method for managing low computing resource state

In general, embodiments relate to methods and systems for signing a software image (SWI), distributing the signed SWI to one or more network devices, and verifying, on a per-network device basis, the signed SWI.

Method and system for software image verification using a Null File

A method for detecting abnormalities in network element operation. The method includes monitoring at least a portion of the network element for abnormalities and making a determination that an abnormality exists, in response to the monitoring, and based on the determination, tracking the abnormality. An abnormality includes a measured performance that deviates from a nominal performance, but that does not cause erroneous behavior of the network element.

A network device for performing bidirectional forwarding detection (BFD) includes a processor that receives packets from a peer; a session state machine that manages a session with the peer; a receive module that determines whether the packet indicates no change to the session; and a transmit module. The transmit module transmits BFD packets at an interval determined by the session state machine and transmits a session change packet in response to a configuration update by the session state machine.

Bidirectional forwarding detection accelerator

Method and apparatus for migrating a volume and a virtual disk from a first storage controller to a second storage controller in a distributed storage system having volumes and virtual disks associated with storage controllers. In one embodiment, the virtual disk is migrated to the second storage controller, and requests for data reads/writes associated with the virtual disk are routed to the second controller. Further, in another embodiment, the volume is migrated to the second storage controller, and requests for data reads/writes associated with the volume are routed to the second controller. A contact address may be associated with a plurality of storage controllers and once a session between an application server and a volume is established, the application server may be redirected so as to communicate with the storage controller associated with the volume using the IP address of the storage controller. In this manner, the volumes and the virtual disks may be migrated, independently if desired, to other storage controllers in the network without disrupting the data flow between the application server and the storage controllers.
