Abstract: This disclosure describes various methods, systems, and devices related to dynamic service node discovery in a network. In an example method, an intermediary node receives a Link Layer Discovery Protocol (LLDP) message from a first node. The LLDP message includes a discovery Type-Length-Value (TLV) that indicates a location of a service node in the network. The method further includes forwarding the LLDP message to a second node.

Abstract: Network hardware devices organized in a wireless mesh network (WMN). A first mesh network device performs a three-stage discovery protocol; in a first stage, a discovery scan uses a first radio to find a set of neighbor devices in proximity; in a second stage, a discovery locate probe process is performed on a secondary discovery channel that is from a same frequency band group as a first DFS channel; in a third stage, a CAC is performed via the first DFS channel and, after the CAC, a neighbor peering request is sent and a neighbor peering response is received from a second mesh network device via a second radio. The neighbor peering response confirms establishment of a first communication channel between the second radio of the first mesh network device and a radio of the second mesh network device over the first DFS channel.

Abstract: Data services are often provided with consistency guarantees of either strong consistency models, comprising uniform wall-clock consistency, or eventual consistency models, where temporary logical inconsistency is guaranteed to be resolved only after full data propagation. However, the performance characteristics of contemporary services often require an intermediate consistency model, where some aspects of the service have specific consistency expectations and other aspects of the service are flexible, such as bounded staleness (e.g., a maximum delay in reaching consistency); session consistency (e.g., individual sessions remain logically consistent, but ordering may vary across sessions); and prefix consistency (e.g., each view during a session is logically consistent, but ordering may vary between session views).

Abstract: The invention concerns a method (200) of detecting an emulator for an SCR catalytic converter system (10) with the following steps: operating the SCR catalytic converter system (10) in a test state; and measuring a test variable of the SCR catalytic converter system (10); and deciding whether the test variable is behaving as for an SCR catalytic converter system (10) with or without an emulator.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be implemented by at least two computing devices, a first of which is configured as a primary device to which reads from and writes to the volume are directed. Of the two volumes, one can be indicated as primary, indicating authority to accept reads to and writes from the virtualized device. A primary device of the primary volume, on obtaining a write to the volume, can replicate the write to both a secondary device of a primary volume and to the secondary volume.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. In the case of a failed volume, a new volume can be created and populated with data from the surviving volume. During population, new writes can continue to be replicated to the new volume. The population process can write data from the surviving volume to the new volume “under” new writes, such that the population process does not overwrite data included in the new writes.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be implemented by at least two computing devices, a first of which is configured as a primary device to which reads from and writes to the volume are directed. To ensure consistency in the distributed device, a multi-tier authority service is implemented, in which a cross-computing system authority service designates a volume as having authority to accept writes to the virtualized device, and in which a second tier authority service designates a computing device as having authority to accept writes to the volume.

Abstract: Embodiments of the present disclosure are related to a receiver and a method for receiving signal. The method comprises estimating, by a receiver, channel for each of a plurality of antennas using the received signal stream, to produce a plurality of estimated channels. Also, method comprises grouping a predetermined number of received signals from the received signal stream and estimated channels associated with the received signals to obtain a plurality of groups. Further, a group specific filtering is performed on the received signals and corresponding estimated channels of each of the plurality of groups to obtain filtered received signals and a plurality of filtered estimated channels. Thereafter, the method comprises performing second filtering on all the filtered received signals to produce second filtered signals, which are processed to produce an output.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be encrypted with a distinct key, and an encryption service can operate to transform data “in-flight” on the replication path between the volumes, reencrypting data according to the key appropriate for each volume.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Due to separation between volumes, replication lag may occur, in which data persisted to a first volume is not immediately persisted to a second volume. Such lag can increase a potential for data loss in the event that the first volume fails. Embodiments of the present disclosure relate to managing data loss risk by determining an expected maximum difference between the data stored at the two volumes, in a manner that does not require decrypting the data written to the volumes or perfect knowledge of the state of the distributed system at a single point.

Abstract: In one example, a network element in a first network receives a network packet including a first security group identifier. The network element identifies the first security group identifier, determines that the first security group identifier is hierarchically correlated with a second security group identifier, and inserts the second security group identifier into the network packet. The network element forwards the network packet including the second security group identifier.

Abstract: The present disclosure discloses a method and a system for transmitting DFT-s-OFDM symbols. A data sequence for transmitting as an OFDM symbol is received as input from a data source. A reference sequence for transmitting along with the data sequence as the OFDM symbol is generated and time-multiplexed with the data sequence, to generate a multiplexed sequence. Thereafter, a Discrete Fourier Transform (DFT) operation is performed on the multiplexed sequence to generate a DFT-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) symbol that is further processed for transmitting over a channel. The transmission of the reference sequence and the data sequence in a single OFDM symbol provides better bandwidth utilization and flexibility in modulation of the reference sequence and the data sequence.
