Filed:

May 18, 2004

Appl. No.:

10/848644

Inventors:

David K. Bainbridge - Acton MA, US
Mickael Graham - Hopkinton MA, US
Neil Russell - Wakefield MA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 11/00

US Classification:

714 38, 714 47

Abstract:

An approach for facilitating the analysis of computer software errors generally involves logging status data in a volatile memory, such as a random access memory (RAM). The status data may indicate one or more attributes of a computing system or any of its components. The status data may be supplemented with additional status data to indicate attributes of the computing system and its components over time. In response to detecting a specified condition, the status data is written from the volatile memory to a non-volatile memory, for example, onto one or more disks. The status data stored on the non-volatile memory may then be used to analyze the behavior of the computer software over time leading up to the computer software error.

Inventors:

Kenneth Kinnear, JR. - Boxborough MA, US

Mark Stapp - Boxborough MA, US
Bernard Volz - Center Harbor NH, US

International Classification:

G06F 15/177

US Classification:

709221, 709206

Abstract:

In an embodiment, a data processing apparatus comprising one or more electronic digital processors; Dynamic Host Configuration Protocol (DHCP) server logic coupled to the one or more processors; an active leasequery channel response logic coupled to the DHCP server logic which when executed causes the one or more processors to perform receiving, from a particular DHCP client among a plurality of DHCP clients, an active leasequery initiation message requesting the DHCP server logic to actively send update messages about changes in network address leases that the DHCP server logic manages; wherein the active leasequery initiation message comprises a channel identifier value; determining whether the channel identifier value matches a client class that the DHCP server logic manages; in response to determining that the channel identifier value does match a client class identifier that the DHCP server logic manages, sending, to the particular DHCP client, one or more DHCP response messages describing any changes in network address leases that the DHCP server logic performs only for a subset of the DHCP clients that are in the matched client class.

International Classification:

US Classification:

719321

Abstract:

An improved technique for communicating with components of an electronic system includes operating a driver according to a designated protocol but agnostically to the components themselves. Information about particular system components is supplied to the driver by respective data sources. To obtain discovery information about a component, the driver accesses a data source for the component and communicates with the component using the designated protocol. The driver thus operates merely as a conduit for component-specific information, which is supplied by the data sources rather than by the driver itself.
