摘要： A programmable device employs an address and data corruption logic for data written to a first memory. A first signature is computed from the data stored in the first memory and stored in a second memory. When data is read from the first memory, the first signature stored in the second memory is read and compared with a second signature computed from the data read from the first memory. If the first and second signatures do not match, an error condition is indicated.

摘要： Apparatuses and methods to mirror frames received at an input port or provided by an output port to a port not connected to the device performing the mirroring operation. A frame being sent to a diagnostic system has a mirror header added to allow the frame to be routed through any intervening switches in the same fabric. The final switch or the diagnostic system removes the mirror header. If the diagnostic system is attached in a different fabric, encapsulation and inter-fabric routing headers are added as needed to the frame containing the mirror header. This allows the frame to traverse multiple fabrics to reach the diagnostic system. The encapsulation and inter-fabric routing headers are removed as done normally. This allows a diagnostic system to be connected to any switch in the network, either in the same or a different fabric.

摘要： A switch creates and dynamically updates a latency map of a network to adjust routing of flows. Further, the network is monitored to detect latency issues and trigger a dynamic adjustment of routing based on the latency map. In this manner, a flow can be routed along a route (i.e., a faster route) that provides less latency than other available routes. The latency map can be generated based on latency probe packets that are issued from and returned to the source switch. By evaluating many such latent probe packets that have traveled along many available routes (e.g., corresponding to various ports of the switch), the switch or associated administrative logic can dynamically adjust the latency map to updated latency information of available routes. Therefore, responsive to a trigger, the source switch can dynamically adjust the routing of a flow based on latency issues discerned from the network.

摘要： Pluggable transceiver modules with additional functions and circuitry contained within the module. In a first embodiment, additional circuitry is added to determine bit error rates at the point of the module itself. This allows a much better diagnostic evaluation of location of problem. In an alternate embodiment, various logic is placed in the module. In a first alternate embodiment encryption/decryption units are placed in the converter module so that encryption and decryption operations on the serial bitstream do not need to be performed in a switch. Existing switches can be used but the interconnecting links can still be encrypted. A second alternate embodiment includes compression/decompression units placed in the module to allow effective higher throughput on the selected links.

摘要： A programmable device employs an address and data corruption logic for data written to a memory. A first signature is computed from the data stored in the memory and the address at which it is stored. The signature is stored with the data in the memory. When data is read from the memory, the first signature stored in the memory is also read and compared with a second signature computed from the data read from the memory and the address from which it is read. If the first and second signatures do not match, an error condition is indicated.

摘要： A network system provides network device having a secondary memory that mirrors the content of a primary memory maintaining data structure parameters entries. The integrity of each data structure parameter entry is tested as the entry is output from the primary memory, such as by using a parity test. If an error is detected in the entry, a corresponding entry from the second memory structure is select for use instead of the entry from the primary memory. The corresponding entries in each memory are then flushed, updated, synchronized, or overwritten from the each memory and processing continues using the new entries or other entries from the primary memory. In the rare instance that corresponding entries from both memories exhibit an error, then an error notification is issued.
