Abstract: Video messaging may be provided. First, a bootstrap message including a system address may be transmitted by a high level device. A user device may receive the bootstrap message from the high level device and obtain system data from the system address contained in the received bootstrap message. The user device may then determine a service group in which the user device is deployed. Next, the user device may determine, from the obtained system data, a sub-system address corresponding to the determined service group. The user device may then obtain sub-system data from the sub-system address.

Abstract: In one embodiment, efficient content-addressable memory entry integrity checking is performed that protects the accuracy of lookup operations. Single-bit position lookup operations are performed resulting in match vectors that include a match result for each of the content-addressable memory entries at the single-bit position. An error detection value is determined for the match vector, and compared to a predetermined detection code for the single-bit position to identify whether an error is detected in at least one of the content-addressable memory entries. In one embodiment, a particular cumulative entry error detection vector storing entry error detection information for each of the content-addressable memory entries is updated based on the match vector. The particular cumulative entry error detection vector is compared to a predetermined entry error detection vector to determine which, if any, of the content-addressable memory entries has an identifiable error, which is then corrected.

Abstract: One or more operational parameters associated with pluggable optical transceivers are estimated to mitigate impairments to an optical signal caused by imperfections in the optical transceivers. A monitoring algorithm within a receiver signal processor may further use the estimated operational parameters associated with the pluggable optical transceivers to determine whether the transceivers are performing correctly. If the monitoring algorithm determines that either the transmitting or receiving optical transceiver is not functioning correctly, it may generate an alarm signal to notify a system administrator about the damaged device.
