Abstract: A method for tracking a process is disclosed. Requests are received from process threads according to a time order. A request requests a buffer entry operable to record a trace message from a process thread of a process. A first buffer entry is assigned to a first process thread associated with a trace message according to the time order. A second buffer entry is assigned to a second process thread according to the time order subsequent to the assignment of the first buffer entry. The trace message associated with the first process thread is written to the first buffer entry in response to the assignment of the first buffer entry.

Abstract: In accordance with one embodiment of the invention, a method for replicating data for redundant network components is disclosed. Data associated with a call is received and stored in a shared memory database. The data is sent to a mate network component of the network component if the network component is in an active mode. Sending of the data to the mate network component is terminated if the network component enters a mode other than the active mode.
