Abstract: A fault tolerant communication protocol transmits information across a communication channel from a transmitting device to a receiving device. The receiving device echoes back a copy of the transmitted information to the transmitting device. The transmitting device sends a first valid signal across the communication channel if the echoed information matches the transmitted information. The receiving device sends a second valid signal across the communication channel responsive to the first valid signal. The transmitting device stops sending of the first valid signal responsive to the second valid signal and the receiving device stops sending the second valid signal responsive to determining the first device has stopped sending the first valid signal. The receiving device can then update its state based on a successful transfer.

Abstract: Techniques described herein may be used to identify communication sessions (e.g., voice calls, video calls, etc.) that can be routed using local network resources, such as a base station to which the user devices are attached, and cause routing responsibilities for the session to be offloaded to the local network resources. Doing so may conserve network resources by alleviating the core network from having to support communication sessions that do not need to be routed through the core network. In turn, this may reduce the potential for network latency since: 1) core network resources will be more available to support sessions that actually need to be routed through the core network; and 2) sessions that do not need to be routed through the core network can be routed over shorter distances that involve fewer network devices (e.g., a based station).

Abstract: A method for replicating data between two or more network connected data storage devices, the method including dynamically determining whether to compress data prior to transmitting across the network based, at least in part, on bandwidth throughput between the network connected data storage devices.

Dynamically determining whether to compress data may include comparing bandwidth measurements with a predetermined policy defining when compression should be utilized. In some embodiments, the policy may define that compression should be utilized when an estimated time for compressing the data and transmitting the compressed data is less than an estimated time for transmitting the data uncompressed.
