摘要:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing network devices. A central management system stores shared configuration objects in a central configuration database. A network device stores shared configuration objects and device-specific configuration objects in a local configuration database. The local configuration database's shared configuration objects correspond to shared configuration objects in the central configuration database. The network device can be configured locally or using the central management system.
摘要:
Packet processing is provided in a multiple processor system including a first processor to processing a packet and to create a tag associated with the packet. The tag includes information about the processing of the packet. A second processor receives the packet subsequent to the first processor and processes the packet using the tag information.
摘要:
Computer program products and methods of inspecting a log of security records in a computer network are provided. The method includes retrieving a log record, processing the log record including deriving a key to a table, determining a data value from information in the log record and adding the data value to a list of data values associated with the key if the data value is unique. One or more entries of the table are evaluated based on predetermined criteria to detect attempted security breaches.

摘要:
Methods and apparatus for processing data packets in a computer network are described. One general method includes receiving a data packet; examining the data packet to classify the data packet including classifying the data packet as a L2 or L3 packet and including determining at least one zone associated with the packet; processing the packet in accordance with one or more policies associated with the zone; determining forwarding information associated with the data packet; and if one or more policies permit, forwarding the data packet toward an intended destination using the forwarding information.
摘要:
Methods and apparatuses are described for inspecting data packets in a computer network. One or more data packets through the network have associated header data and content. One method includes receiving a data packet, examining the data packet to classify the data packet including classifying the data packet using information included in the header and content, determining flow instructions for processing the packet based on both the header information and the content and processing of the packet using the flow instructions.
摘要:
Methods, systems, and apparatus, including computer program products, featuring receiving at a network device a plurality of packets associated with a flow, one or more of the plurality of packets having associated header data and content. Based on the content of one or more first packets in the plurality of packets, the network device identifies an application associated with the flow, where none of the first packets is addressed to the network device. For one or more second packets associated with the flow, the network device determines a forwarding destination for the second packets based on the application associated with the flow and forwards the packet according to the determined forwarding destination.

摘要:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing a first plurality of packets using one or more processors and maintaining one or more flow records associated with the first plurality of packets, and processing a second plurality of packets without maintaining flow records associated with the second plurality of packets and allowing the second plurality of packets to pass to one or more destinations.
