Abstract: Some embodiments provide a method for identifying security threats to a datacenter. From multiple host computers in the datacenter, the method receives data indicating port usage for a particular time period for each of multiple destination data compute nodes (DCNs) executing on the host computers.

Abstract: Systems and methods for routing traffic through a network along Label-Switched Paths (LSPs) that may extend across multiple autonomous systems include performing Internet Protocol (IP) routing lookups as a packet is transmitted along the LSP. In one implementation, a packet having a predetermined value (which may be inserted by an upstream network device) is received at a network device after travelling along a first segment of an LSP. In response to identifying the predetermined label value of the packet, the network device may perform an IP routing lookup using IP routing information included in the packet to identify a next hop for the packet. The network device may then update a label of the packet such that the packet is routed along a second segment of the LSP and transmit the communication packet to the next hop.

Abstract: Many computing systems process data organized in a matrix format. For example, artificial neural networks (ANNs) perform numerous computations on data organized into matrices using conventional matrix arithmetic operations. One such operation, which is commonly performed, is the transpose operation. Additionally, many such systems need to process many matrices and/or matrices that are large in size. For sparse matrices that hold few significant values and many values that can be ignored, transmitting and processing all the values in such matrices is wasteful. Thus, techniques are introduced for storing a sparse matrix in a compressed format that allows for a matrix transpose operation to be performed on the compressed matrix without having to first decompress the compressed matrix. By utilizing the introduced techniques, more matrix operations can be performed than conventional systems.

Abstract: A reservation request is received for a data transport session. The reservation request contains a requested class of communication service through the asynchronous network. The state of the network along the route is then preferably determined and at least one end-to-end route through the network is obtained. The route is based on the requested class of communication service and the state of the network. The data transport session is then controlled, such that data is forced to travel along at least one route through the asynchronous network. This is preferably done by controlling multiple data controllers dispersed along the at least one route by mapping specific data protocols to specific routes, or mapping specific data protocols to specific ports in each data controller. If a state of the asynchronous network indicates that the route cannot transport data in conformity to the class of communication service, then the route is changed to a backup route through the network.

Abstract: Interference cancellation in a receiver can be used to improve bandwidth efficiency. The transmission of bursts from different terminals scheduled at separate time intervals can overlap partially such that time used for information transmission is optimized. For example, a receiver includes a signal processor including instructions executable to select first data including a first burst and a successive second burst from a transmission. The signal processor demodulates and decodes information from the first burst. The signal processor further generates a remodulated first burst based on recoded and remodulated information and generates second data by subtracting the remodulated first burst from the first data. The signal processor synchronizes with a stored symbol pattern in the second burst; and demodulates and decodes the information from the second burst. With such arrangement, the performance of each link is not affected by the partially overlapping burst.

In addition, the disclosed backscatter modulator provides amplitude modulation so that the technique can provide a non-constant envelope which can provide an intentional imbalance to manipulate super-position to provide envelope control of the reflected signal, while still maintaining the frequency translation properties. The disclosed backscatter modulator thus allows compatibility with QAM, OFDM and other non-constant envelope modulation schemes to be backscattered, while still supporting the frequency translation behavior.

When those allocated addresses are presented to the kernel, the addresses are transformed to effective addresses, which may be both randomized (e.g., not easily predictable from the allocated address) and/or obscured from the user space processes.

Abstract: A system for creating a session entry and forwarding an IP packet includes memories that store session and session template tables, and first and second processors in communication with the memories. When the first processor receives the IP packet, it determines whether the session table includes a session entry corresponding to the IP packet. If the session table does not include the session entry, the first processor determines whether the session template table includes a session template entry corresponding to the IP packet. The first processor generates the session entry using the session template entry and the IP packet. If the session template table does not include the session template entry, the first processor forwards the IP packet to the second processor, which generates the session template entry and the session entry.
