A method, apparatus, and machine readable storage medium is disclosed for balancing loads among a plurality of virtual machines (VMs) from a central dispatcher, wherein the dispatcher receives data packets and maps the data packets to VMs selected from the plurality of VMs, using a weighted hash function, having an associated weighting for each VM and forwarding each packet to a VM accordingly, wherein a load balancer decrements a weighting for a VM, responsive to an indication of the load on the VM exceeding a first load threshold. Weightings can correspond to a number of bins associated with each VM. Weightings are adjusted in response to receiving invite and disinvite messages from the VMs, representing their respective loads.

The present disclosure generally discloses various mechanisms for supporting multipath communications, including mechanisms for supporting retransmissions for multipath communications. The mechanisms for supporting retransmission for multipath communications may be provided within the context of multipath transport connections, such as Multipath Transmission Control Protocol (MPTCP) connections. The mechanisms for supporting retransmission for multipath communications may support retransmission of lost or delayed packets of a multipath transport connection in a manner tending to avoid a timeout of the multipath transport connection.

Fast coupled retransmission for multipath communications

Methods and apparatuses for real-time adaptive placement of a virtual machine are provided. In an embodiment, a virtual machine is received at a routing component, the routing component having a processor in communication with a memory. By the processor in communication with the memory, a target data center is determined from a plurality of data centers based on a data center index, and the virtual machine is routed to the target data center. A physical machine is chosen within the target data center for placing the virtual machine.

A gigabit passive optical network or other type of optical communication network comprises an optical line terminator that transmits data in a downstream direction to multiple optical network units. The optical network units transmit data in an upstream direction to the optical line terminator. In one aspect of the invention, the optical line terminator is operative to allocate upstream bandwidth among the optical network units, to measure usage of the allocated upstream bandwidth by the optical network units, to process the measured usage to determine a predicted variation in usage of upstream bandwidth by the optical network units, and to alter the allocation of the upstream bandwidth based on the predicted variation.

A method of operating a packet network includes the step of selecting one of a plurality of candidate gateways to connect a multimedia communication session between the packet network and a TDM network. The packet network has a source node of the multimedia communication session, and the TDM network has a destination of the multimedia communication session. The candidate gateways interconnect the packet network and the TDM network. The selecting step includes comparing end-to-end congestions for bearer traffic between the source node and different candidate gateways of the plurality.

An apparatus includes a first node configured to receive the data packets from a plurality of source nodes of the data network and to selectively route some of the received data packets to a link via a port of the first node. The apparatus also includes a link-input buffer that is located in the first node and is configured to store the some of the received data packets for transmission to the link via the port. The first node is configured to power off hardware for transmitting received data packets to the link in response to a fill level of the link-input buffer being below a threshold.

A method includes transmitting a list of willingness-to-pays for optical data capacities to an optical network. The optical network has a set of gateway nodes connected directly to nodes of a data network. The optical network is configured to transmit data communications on a plurality of wavelength channels. Each willingness-to-pay represents a value for an optical data capacity between a corresponding pair of the gateway nodes of the optical network.

Hybrid optical and data networks

In the operation of an MPLS network or the like, a network node receives a plurality of packets assigned to a label switched path (LSP) which exits the node on a link bundle. The node forwards the received packets such that packets assigned to the LSP are distributed over two or more distinct component links of the bundle.
