An apparatus comprising a processor configured to migrate load from a source process running on the processor to a target process running on a peer processor in a dynamic manner by monitoring an amount of resources used by the source process, wherein the load is migrated when the amount of resources utilized by the source process exceeds a threshold. Also disclosed is a network component comprising a first processor configured to select a source process to migrate a load from the first processor based on available resources on the first processor and the source process; and a second processor configured upon receiving a migration request from the first processor to one of select and start a target process to which to migrate the load based on available resources for the second processor and the target process.

Method for dynamic migration of a process or services from one control plane processor to another

An apparatus comprising a processor configured to startup a new process on a peer processor to off-load a load of a local process on the processor in a dynamic manner based on monitoring an amount of resources used by the processor, wherein the startup of the new process on the peer processor is initiated when the amount of resources used by the local process reaches a threshold.

Method for dynamic on demand startup of a process or resource

An apparatus comprising a proxy configured to couple to a sender and a receiver and to receive data from the sender at a first rate and forward the data to the receiver at a second rate that is less than the first rate. A method comprising detecting a reception speed for each of a plurality of receivers in a multicast group, assigning the receivers to a first group and a second group based on the reception speed of each of the receivers, wherein the first group has a reception speed that is faster than a reception speed of the second group, and sending multicast data intended for all of the receivers to the receivers in the first group and to a proxy at a first rate, wherein the proxy buffers the multicast data and sends the multicast data to the receivers in the second group at a second rate.

Method for group-based multicast with non-uniform receivers

A method in a network device with a processor that runs multiple software threads for software that needs an update for updating the software while mitigating service disruption, the method comprising installing at least one new function, modifying at least one existing function to point to a synchronization code, wherein the synchronization code indicates whether the multiple software threads use the at least one new function or the at least one existing function, synchronizing software threads in the network device, based on the synchronization code indicating that the synchronization of the software threads is not complete, using, by the multiple software threads, the at least one existing function, and based on the synchronization code indicating that the synchronization of the software threads is complete, using, by the multiple software threads, the at least one new function, wherein the multiple software threads continually run on the network device during the synchronization.

In-service software patch

A communication system, comprising a multicast group address allocator in communication with a plurality of nodes configured as at least one multicast group, wherein, upon creation of a new multicast group from among the nodes, the multicast group address allocator is configured to assign a multicast address to the new multicast group based on the assigned multicast address falling into a hash-bin for each group member of the new multicast group. A multicast group address allocator, comprising a network interface in communication with a plurality of nodes, a controller coupled to the network interface, and a storage medium coupled to the controller, wherein, upon request, the controller assigns a multicast address to a new multicast group from among the nodes, wherein the controller accesses hash-bin information for the nodes and selects the multicast address based on the hash-bin information, and wherein the hash-bin information is stored in the storage medium.

Determining the group address for an Ethernet-based multicast communication

In at least some embodiments, a multicast communication system includes sender and a plurality of receivers in communication with the sender. The sender is configured to multicast a data packet to the plurality of receivers. The plurality of receivers are configured to acknowledge the data packet received from the sender based on weakest member selection without a sender-side competitive time window.
