In some implementations, a device may identify a set of characteristics of a frame. The device may compute a first key index associated with the frame based on the set of characteristics and using a first key index function. The device may determine whether the first key index is associated with any collision entries from a set of collision entries. The device may determine a set of security parameters associated with the frame using a particular key index. The particular key index is either the first key index when the first key index is not associated with any collision entries from the set of collision entries, or is a second key index when the first key index is associated with a collision entry from the set of collision entries.

Secure communication acceleration using a frame classifier

A device may include a buffer memory to buffer frames received or to be transmitted via a plurality of ports of the device. The device may include at least one frame processor to process frames. The device may include a buffer manager to store a frame in the buffer memory. The buffer manager may allocate at least one buffer control block (BCB) to the frame based on storing the frame in the buffer memory. The buffer manager may allocate a frame control block (FCB) to the frame. The FCB may include information that identifies the at least one BCB. The buffer manager may perform one or more queueing operations in association with processing of the frame by the at least one frame processor. The one or more queuing operations may be performed using information associated with the FCB.

Buffer management in an ethernet switch

In various embodiments, an alarm handling circuitry is provided. The alarm handling circuitry may include a first alarm processing circuit configured to process a first received alarm and to provide a first processed alarm response signal, a second alarm processing circuit configured to process a second received alarm and to provide a second processed alarm response signal, and an interface between the first alarm processing circuit and the second alarm processing circuit configured to input an alive indication signal from the first alarm processing circuit to the second alarm processing circuit indicating whether the first alarm processing circuit is operating.
