| 20120076140 | Method and Apparatus for Improving Packet Processing Performance Using Multiple Contexts - A network processing device having multiple processing engines capable of providing multi-context parallel processing is disclosed. The device includes a receiver and a packet processor, wherein the receiver is capable of receiving packets at a predefined packet flow rate. The packet processor, in one embodiment, includes multiple processing engines, wherein each processing engine is further configured to include multiple context processing components. The context processing components are used to provide multi-context parallel processing to increase throughput. | 03-29-2012 |
| 20110242968 | Method and Apparatus for Improving Network Communication Using BFD and VRRP Tracking System - An apparatus and method of a network system between a host and a group of routers using virtual router redundancy protocol (“VRRP”) messages and bidirectional forwarding detection (“BFD”) sessions are disclosed. The network system is capable of facilitating a first communication between a host and a master router of multiple VRRP routers and establishing a BFD session between the host and the master router. When the BFD session fails, the priority of the master router is subsequently lowered and a backup router is activated. In one embodiment, the backup router capable of performing functions of the master router becomes a new master until the BFD session resumes. | 10-06-2011 |
| 20110035480 | Re-Synchronizing Data Between Network Elements And Network Management System Using Partial Node Discovery - An apparatus and method for improving network efficiency for data transfer utilizing partial node discovery a during system recovery are disclosed. Upon retrieving a saved last sequence number associated with a network element (“NE”) from a database in a network management system (“NMS”), a process of the partial node discovery obtains a current last sequence number associated with the NE from the NE. After identifying missing sequence numbers associated with the NE, sequence events associated with the NE in the database are updated in accordance with the missing sequence numbers. | 02-10-2011 |
| 20090204697 | Methods and apparatus for extended error reporting in network management - Standard SNMP error reporting between a network element and a management system utilizes a set of standard error codes that provide limited information about a fault condition. Example embodiments of the invention provide reporting of an extended error code that provides information for locating the source of a fault condition and for debugging the fault condition. In response to a first request, the extended error code can be reported to a management system. In response to a request following the extended error code, meanings associated with the extended error code are reported to a management system, thereby informing a network administrator of the fault condition. | 08-13-2009 |
| 20090201923 | APPARATUS AND METHOD FOR A FAULT-TOLERANT SCALABLE SWITCH FABRIC WITH QUALITY-OF-SERVICE (QOS) SUPPORT - Embodiments of the present invention relate to portions of a switch fabric having a single logical stage and at least one physical stage. In addition, the data paths and the control paths of the switch fabric can be decoupled thereby allowing additional processing to be performed than would otherwise be the case with control rates that matched the high data rates. In other words, data cells received on high speed links can be spread over many lower speed links; consequently, the data cells can transit the switch fabric at that high speed while the control information associated with the data can be processed at that lower speed. Because the control information can be processed at a lower speed (associated with the control path), the control information can be processed over a greater period of time. | 08-13-2009 |
| 20090094521 | METHOD AND APPARATUS TO AUTOMATE CONFIGURATION OF NETWORK ENTITIES - A method and apparatus for automating the configuration of network entities with a network management system. More particularly, a graphical user interface incorporates a template to allow administrators to configure attributes of network entities. The graphical user interface and template reduce the number of blocks required to configure network entities and also minimize user errors. The graphical user interface also allows an administrator to add and manage templates for future use. The method and apparatus are also for monitoring the progress of configuring network entities and generating an operation log. | 04-09-2009 |
| 20090089414 | REPORTING MULTIPLE EVENTS IN A TRAP MESSAGE - A method for reporting events relating to objects of a network element manageable by a network management device, using a network management protocol, and devices, a network, and computer-readable storage medium storing control logic, that operate in accordance with the method. Events for each object are detected, event information is generated for detected events, generated event information for multiple events is packaged into a trap message for each object type, the trap message is communicated from the network element to the network management device, and the event information from the communicated trap message is unpacked at the network management device. In this manner, network congestion and processor overload at the network management device can be reduced. | 04-02-2009 |
