Abstract: Methods and systems for identifying a source of an attack in a network include transmitting an address associated with the attack target to a number of network devices. Each network device may then determine whether a received packet is destined for the attack target and identify, for each packet destined for the attack target, an input interface upon which the packet arrived. Each network device may also count the amount of data destined for the attack target per input interface. A potential source of the attack may then be identified based on the amount of data destined for the attack target.

Abstract: A printed circuit board (PCB) includes a ball grid array (BGA). The PCB further includes a first BGA pad having a circular shape, and a first via having a circular shape, where the circular shape of the first via overlaps a portion of the circular shape of the first BGA pad and is rotated diagonally relative to a center of the first BGA pad. The PCB also includes a second BGA pad having a circular shape, and a second via having a circular shape, where the circular shape of the second via overlaps a portion of the circular shape of the second BGA pad and is rotated diagonally relative to a center of the second pad, and where a center of the second via is located at a first distance from the center of the first via and at a first angle relative to an axis that crosses a center of the first via.

Abstract: Output logic generates read requests using a programmable schedule that controls read bandwidth for multiple data streams and stores the read requests in a queuing device. The output logic also dequeues the read requests based on a similar programmable schedule, forwards the read requests to the memory, and reads data units from the memory based on the read requests.

Abstract: A device may include a plurality of direct current to direct current (DC/DC) converters that may produce voltages, and a first device that may receive a signal from a second device on a removable module when the removable module is coupled to the device. The first device may produce, based on the signal, an instruction related to one or more voltages associated with the removable module. The instruction may cause a first DC/DC converter and a second DC/DC converter, of the plurality of DC/DC converters, to power up at different times based on a particular sequence, and generate the one or more voltages. The particular sequence may be based on the signal. The first device may cause the one or more voltages, generated by the first DC/DC converter and the second DC/DC converter, to be provided to the removable module.

The processor may execute the instructions to conduct an initial cell optimization for an integrated circuit layout; designate clock loads associated with a first-level clock buffer; receive, after the initial standard-cell optimization, a set of initial placement locations; align the clock loads according to the set of placement locations; conduct, using the aligned clock loads, a re-optimization of the integrated circuit layout; and store, in the memory, a circuit layout based on the re-optimization.

Abstract: A switch fabric for a modular router may be tested without connecting the switch fabric portion of the router to the other modular portions of the router. The switch fabric may generate test data units and insert the test data units into one or more elements of the switch fabric. The switch fabric may operate with the inserted test data units. A control component may receive data units from the switch fabric after operation of the switch fabric and analyze the received data units to determine whether the received data units correspond to the inserted test data units.

Abstract: A system may determine an extent to which a document is selected when the document is included in a set of search results, generate a score for the document based, at least in part, on the extent to which the document is selected when the document is included in a set of search results; and rank the document with regard to at least one other document based, at least in part, on the score.

Abstract: A network device may include an off-chip memory to store a free-list of buffer pointers. The network device may further include an on-chip controller that includes a prefetch buffer. The prefetch buffer may store unallocated buffer pointers that point to available memory locations in a different off-chip memory. The on-chip controller may receive an unallocated buffer pointer, determine, in response to receiving the unallocated buffer pointer, whether the prefetch buffer is full, store the unallocated buffer pointer in the prefetch buffer when the prefetch buffer is determined not to be full, and store the unallocated buffer pointer in the free-list, in the off-chip memory, when the prefetch buffer is determined to be full.

Abstract: A system receives a search query from a user and searches a group of repositories, based on the search query, to identify, for each of the repositories, a set of search results. The system also identifies one of the repositories based on a likelihood that the user desires information from the identified repository and presents the set of search results associated with the identified repository.

Abstract: Techniques for crawling hyperlinked documents are provided. Hyperlinked documents to be crawled are grouped by host and the host to be crawled next is selected according to a stall time of the host. The stall time can indicate the earliest time that the host should be crawled and the stall times can be a predetermined amount of time, vary by host and be adjusted according to actual retrieval times from the host.

The system may chunk memory to form a set of memory chunks which have memory blocks, at least some of the memory blocks including database objects. The system may configure at least one binary search tree using the memory chunks as nodes and buffer a set of pointers corresponding to the memory blocks. The system may further validate the buffered pointers and dereference validated buffered pointers.

Abstract: A method includes receiving a data unit, determining whether a current state, associated with a deterministic finite automata (DFA) that includes a portion of states in a bitmap and a remaining portion of states in a DFA table, is a bitmap state or not, and determining whether a value corresponding to the data unit is greater than a threshold value, when it is determined that the current state is not a bitmap state. The method further includes determining whether the current state is insensitive, when it is determined that the value corresponding to the data unit is greater than the threshold value, where insensitive means that each next state is a same state for the current state, and selecting a default state, as a next state for the current, when it is determined that the current state is insensitive.

Abstract: A first network device creates a protection path to a second network device associated with a first service site, and creates a pseudowire between the first service site and a second service site via the first network device and the second network device. The first network device also detects a failure between the first network device and the first service site, and forwards traffic, provided by the pseudowire between the first service site and the second service site, via the protection path. The second network device uses the traffic on the protection path as a trigger to activate a link between the second network device and the first service site.
