Abstract: To accommodate graceful offloading of connections from a port of a network element, thereby allowing the port to be decommissioned, both existing and new connections allocated to that port according to a load balancing protocol are replicated on a backup port. Thereafter, or concurrently therewith, the port is configured to drop acknowledgements of the new connections, and the port is monitored so as to eventually identify an absence of connections thereon. At that time, the port may be decommissioned inasmuch as all new connections will have been established on the backup port and no previously existing connections on the original port will remain.

Abstract: A method for parallel processing of ingress packets destined to a plurality of inline tools is provided. An ingress packet is processed to extract a plurality of packet header fields and to generate a packet identifier. A hash index is generated by hashing information associated with the plurality of packet header fields. A copy of the ingress packet and the packet identifier are stored in a hash table entry using the generated hash index. The ingress packet is simultaneously forwarded to each of the plurality of inline tool devices.

Abstract: An access request is transmitted from a first device to a second device causing one or more security functions to be executed on the first device. Whether to grant the access request is based on a result of the executed one or more security functions.

Abstract: Proactive and dynamic assistance is provided to a user of a computer system. In particular, the present invention provides a navigation model that integrates help information, task guide information, interactive wizard information or other user assistance information, for example, into a single user assistance system. Additionally, code for the user assistance system is maintained separately from code for an application program for the computer system.
