US Patent:

7171457, Jan 30, 2007

Filed:

Sep 25, 2001

Appl. No.:

09/963806

Inventors:

Reid Evan Wilson - Cary NC, US
Philip Austin Shafer - Raleigh NC, US
Robert P Enns - San Jose CA, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G06F 15/16

US Classification:

709219, 709203, 709217, 709226

Abstract:

Processing of numeric addresses is facilitated by using a user interface, rather than system modules, to handle name resolution. Processing the addresses at the user interface level avoids delays and packet blocking problems associated with using system modules to perform the task. Relieving the system modules from the responsibility of processing numeric addresses allows them to process other requests, improving overall system efficiency.

Appl. No.:

11/511015

Inventors:

Philip A. Shafer - Raleigh NC, US
Reid E. Wilson - Cary NC, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G06F 11/00

US Classification:

714 48, 714 20, 714 49, 714 57

Abstract:

In general, the invention facilitates diagnosing fault conditions, such as flapping, by permitting users to request information for specific components in a network device such as a router. The invention also facilitates the diagnosis of other fault conditions, including, but not limited to, excessive numbers of dropped packets, hard drive crashes, high temperature readings, and inactive interface cards. A user may obtain a targeted log containing information relating to selected fault conditions or other network device events, rather than a system log containing information relating to all network device events, some of which may not be of interest to the user. The targeted log may be parsed and analyzed with greater ease than the system log.

Appl. No.:

10/247803

Inventors:

Philip A Shafer - Raleigh NC, US
Reid E Wilson - Cary NC, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G06F 15/177
G06F 15/173

US Classification:

709220, 709223, 709224

Abstract:

A network device displays applied and non-applied configurations in different formats to facilitate distinguishing between active and inactive configurations. In this way, a user can readily distinguish, for example, between applied configurations for active interfaces from loaded configurations for inactive interfaces and non-applied configurations for active interfaces. Configuration information may be encoded using an extensible markup language to identify the type of configuration. The network device uses this type identification to determine whether a particular part of the configuration should be displayed in as normal text or as altered text. The part of the configuration that is displayed in the altered form may represent the non-applied configurations.

Appl. No.:

10/756960

Inventors:

Reid E. Wilson - Cary NC, US
Philip A. Shafer - Raleigh NC, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G06F 17/30

US Classification:

707 3, 707 8, 709213

Abstract:

Techniques are described for reliable restoration of archived configuration. For example, a device, such as a router, comprises a first memory to store operational configuration data and a second memory to store candidate configuration data. The candidate configuration data represents a working copy of the operational configuration data. The device further includes a control unit to lock the candidate configuration data, load archived configuration data to replace the locked candidate configuration data and commit the candidate configuration data to restore the archived configuration data as the operational configuration data of the device. In locking the candidate configuration, the device ensures reliable restoration of the candidate configuration by helping prevent the device from becoming both unreachable and inoperable.
