    摘要: Event processing in rate limited network devices is described. An event receiver is notified of a backlog condition and may respond by increasing the rate limit for the network device. If an event queue on the network device overflows, event messages may be diverted to an event message overflow store or to a network location. Later, the messages may be retrieved after the overflow condition has cleared. As a result, critical messages or events such as Syslog messages are not lost when a rate limited network device cannot deliver the messages to a network management station.

    摘要: A method is disclosed for a method for measuring the availability of a network element or service. For each network element N, a current real availability value CRAVN and a current time value CTVN are associated with network element N. Additionally, for each network element N, an operational state value OSVN is associated with network element N. At a later time, indicated by a new time value NTVN, a new real availability value NRAVN for network element N is determined based on the current availability value CRAVN, the current time value CTVN, the new time value NTVN, and the operational state value OSVN. The new real availability value NRAVN is stored. Thus, each separate network element N may be associated with a separate real availability value that accurately reflects the availability of network element N specifically, regardless of any availability approximated for network element N's type.
