Patent application number | Description | Published |
20080212579 | Packet tunneling - Network devices, systems, and methods are provided for packet processing. One network device includes a network chip having a number of network ports for the device. The network chip includes logic to select original data packets, based on a set of criteria, received from or destined to a particular port on the device and to tunnel the selected data packets to a second network device having a different destination address to that of the selected data packets. | 09-04-2008 |
20080270606 | Remote client remediation - Embodiments of the invention may include network devices, systems, and methods, including executable instructions and/or logic, for remote client remediation. One method includes identifying a client needing remediation, tunnel-encapsulating packets originating from the client during remediation, and forwarding the tunnel-encapsulated packets to a remote remediation functionality different from an original destination address of the packets and having membership in a remediation VLAN different from the original VLAN. | 10-30-2008 |
20080298392 | Packet processing - Network devices, systems, and methods are provided for packet processing. One method includes receiving a checking functionality rule set as an input to a distribution algorithm. The method includes bifurcating and providing configuration instructions, as an output from the distribution algorithm, to a first logic plane associated with a first logical entity and a second logic plane associated with a second logical entity. A collaboration algorithm is used to provide processing coordination between the first logical entity and the second logical entity. | 12-04-2008 |
20090016226 | Packet monitoring - Network devices, systems, and methods are provided for packet processing. One network device includes a network chip having logic and a number of network ports for the device for receiving and transmitting packets therefrom. The logic is encoded with application specific integrated circuit (ASIC) primitives to check header fields and payload content in the packets. | 01-15-2009 |
20090016336 | Packet processing - Network devices and methods are provided for packet processing. One method includes using logic embedded in an application specific integrated circuit on a network device to dynamically adjust an access control list. According to the method, the access control list is adjusted in response to information received from a checking functionality related to packets received by the network device from a particular port. The method also includes handling packets later received from the particular port according to the adjusted access control list. | 01-15-2009 |
20090154695 | MANAGING A PLURALITY OF CACHED KEYS - In a method of managing a plurality of cached keys, a determination is made as to whether to generate an additional key for the plurality of cached keys. If it is determined to generate the additional key, control of a central processing unit is acquired and a first current time is recorded. While a difference between a second current time and the first current time is not greater than a predefined time slice, one or more operational units of a plurality of operational units for generating the additional key are executed on the central processing unit. If the additional key is completed, the additional key is saved as a cached key with the plurality of cached keys. | 06-18-2009 |
