Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. A customized set of WF muxing on multiple digital files as inputs including at least a data message file and a selected digital envelop file, is configured to guarantee at least one of the multiple outputs comprising a weighted sum of all inputs with an appearance to human natural sensors substantially identical to the appearance of the selected digital envelop in a same image, video or audio format.

The embedded message may be reconstituted by a corresponding WF demuxing processor at destination with the known a priori information of the original digital envelope. In short, digital enveloping/de-enveloping can be implemented via WF muxing and demuxing formulations. WF muxed data featured enhanced privacy and redundancy in data transport and storage on cloud. On the other hand, data enveloping is an application in an opposite direction for conventional WF muxing applications as far as redundancy is concerned. Enveloped data are intended only for limited receivers who has access to associated digital envelope data files with enhanced privacy for no or minimized redundancy.

Reliable replication mechanisms based on active-passive HFI protocols built on top of non-reliable multicast fabric implementations
Methods, apparatus, and systems for reliable replication mechanisms based on active-passive HFI protocols build on top of non-reliable multicast fabric implementations. Under a first hardware-based scheme, a reliable replication mechanism is (primarily) implemented via Host Fabric Interfaces (HFIs) coupled to (or integrated in) nodes coupled to a non-reliable fabric. Under this approach, the HFIs take an active role in ensuring reliable delivery of multicast messages to each of multiple target nodes. Under a second hybrid software/hardware scheme, software running on nodes is responsible for determining whether target nodes have confirmed delivery of multicast messages and sending retry messages for cases in which delivery is not acknowledged within a timeout period. At the same time, the HFIs on the target nodes are responsible for generating reply messages containing acknowledgements rather than software running on the target nodes.
Latency reduction with pre-moving of distributed data and adaptive allocating of compute operations
Latency in responding to queries directed to geographically distributed data can be reduced by allocating individual steps, of a multi-step compute operation requested by the query, among the geographically distributed computing devices so as to reduce the duration of shuffling of intermediate data among such devices, and, additionally, by pre-moving, prior to the receipt of the query, portions of the distributed data that are input to a first step of the multistep compute operation, to, again, reduce the duration of the exchange of intermediate data. The pre-moving of input data occurring, and the adaptive allocation of intermediate steps, are prioritized for high-value data sets. Additionally, a threshold increase in a quantity of data exchanged across network communications can be established to avoid incurring network communication usage without an attendant gain in latency reduction.

Load balancer that avoids short circuits
Network devices, such as load balancers may be configured to route requests to hosts that are responding in a shorter period of time than other hosts. Sometimes hosts respond in shorter periods of time due to errors (they short-circuit). Such behavior may cause a spike in failed requests and increase the impact of a host malfunction. Disclosed is an enhanced load balancing algorithm that reduces request loads to hosts that are responding to request more quickly than expected or historically observed. A load balancer tracks the hosts' performance. Upon detecting response times shorter than expected from a host, the load balancer will reduce the load on the host. The request routing will go back to normal distribution after the host behaving according to its known performance profile.
Inline load balancing
Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN. To direct the data message to the identified DCN, the load balancer in some embodiments changes the destination address (e.g., the destination IP address, destination port, destination MAC address, etc.) in the data message from the address of the identified DCN group to the address (e.g., the destination IP address) of the identified DCN.
