Method for recoverable message exchange independent of network protocols
A method is described to allow a device to retrieve a message, that is separated into a plurality of fragments, from a data source, wherein the method involves: establishing a first network connection with the data source; receiving a subset of the plurality of fragments; determining the first network connection has ended before completion of said message; establishing one or more subsequent network connections with the data source; and receiving any of the plurality of fragments not within the subset. The characteristics (for example: application protocol, security, speed, reach, bandwidth capability, cost of usage, network type, physical layer type, data-link layer type, or ip address of one or both of the first and second devices) of the first network connection can be potentially different than the subsequent network connections..

Programmable physical network topologies for datacenters
The technique described herein programmatically rewires a network topology thus making the datacenter wiring less labor-intensive, less error-prone, and more flexible. The method uses racks with high density connectors so that adjacent racks are interconnected with high density cables, and integrates physical layer switches into racks that route the signals from off-rack cables to either in-rack devices or other off-rack devices.

Link establishment method for multi-wavelength passive optical network system
Provided is a method of establishing a link between service provider equipment and subscriber equipment in a multi-wavelength passive optical network system. The method of establishing a link includes acquiring information about a wavelength plan of allocated wavelengths in the mw pon system; transmitting a first signal wavelength initialization request signal on a first upstream wavelength from physical layer to the service provider equipment; waiting for a response from the service provider equipment for a predetermined time interval after transmitting the first signal wavelength initialization request signal; and in response to failing to receive a response to the first signal-wavelength initialization request signal within the predetermined time interval, transmitting a second signal wavelength initialization request signal on a second upstream wavelength to the service provider equipment after the waiting..

Acknowledgement (ack) type indication and deferral time determination
Certain aspects of the present disclosure provide methods and apparatus for indicating a type of response for acknowledging a protocol data unit. One example method for wireless communications by a first apparatus generally includes transmitting a physical layer convergence protocol (plcp) protocol data unit (ppdu) to a second apparatus and setting at least one bit in a plcp header of the ppdu to indicate a type of response expected from the second apparatus responsive to the transmitted ppdu..
