Abstract: An Orthogonal Time Frequency Space Modulation (OTFS) modulation scheme that maps data symbols, along with optional pilot symbols, using a symplectic-like transformation such as a 2D Fourier transform and optional scrambling operation, into a complex wave aggregate and be backward compatible with legacy OFDM systems, is described. This wave aggregate may be processed for transmission by selecting portions of the aggregate according to various time and frequency intervals. The output from this process can be used to modulate transmitted waveforms according to various time intervals over a plurality of narrow-band subcarriers, often by using mutually orthogonal subcarrier “tones” or carrier frequencies. The entire wave aggregate may be transmitted over various time intervals. At the receiver, an inverse of this process can be used to both characterize the data channel and to correct the received signals for channel distortions, thus receiving a clear form of the original data symbols.

Abstract: A durability assessment system may receive a request, from a computing system, for a durability index describing an entity. The durability assessment system may determine the durability index based on information about the resource usage by the entity, such as a resource availability score or a resource allocation score. The durability assessment system may compare the obtained resource availability score and resource allocation score to ranges associated with a set of durability indices. Based on the comparison, the durability assessment system may determine a durability index for the entity. The durability index may indicate an ability of the entity to return accessed resources. In some cases, the durability assessment system may provide the durability index to an allocation computing system that is configured to determine whether to grant access to resources based on the durability index.

Abstract: The present disclosure provides an approach for scaling the number of VNFs in a data center without scaling the number of control sessions between VNFs and a data center gateway. The approach includes opening a session between a VNF and a route server, rather than between the VNF and the gateway, when the VNF needs to send its connectivity information to the gateway. The VNF sends its connectivity information to the route server, and the route server forwards the connectivity information to the gateway. The gateway receives connectivity information of a plurality of VNFs in the data center from the route server rather than from each of the VNFs individually. The connectivity information is then used to send packets, by the gateway to a VNF, for processing. The packets are sent using three layers of networking: an underlay physical network, an overlay logical network, and a second overlay logical network.

Abstract: Techniques are disclosed for utilizing control packets to manage flows by a smart network interface card (smartNIC). In one example, an accelerator of the smartNIC determines that a cache entry of a cache that is managed by the accelerator is a candidate for removal. The cache entry stores flow state of a particular flow. The accelerator generates a control packet that includes flow information of the particular flow that is formatted utilizing a particular header format, the flow information operable for generating a hash that indexes to the cache entry. The accelerator includes an instruction within the control packet that requests a programming data plane of the smartNIC to provide instructions for removing the cache entry from the cache. Upon receiving the control packet, the programming data plane generates and transmits a second instruction to the accelerator for removing the cache entry from the cache.

Abstract: Systems and methods for network traffic metering credit distribution and packet processing in a network device having multiple processing units are provided. According to an embodiment, management of multiple meters is distributed among multiple processing units of a network device. Each meter is implemented in a form of a master entry and a slave entry. Responsive to receipt by one of the processing units of a packet subject to rate-limiting by a meter, an action to be taken on the packet is made with reference to a slave entry managed by the processing unit based on available credit of the slave entry. When the action indicates the packet is to be passed: (i) credits associated with passing the packet are deducted from the available credit; and (ii) the packet is passed to a subsequent stage of packet processing; otherwise, the packet is dropped.
