Patent number: 8799645Abstract: Web-based authentication includes receiving a packet in a network switch having at least one associative store configured to forward packet traffic to a first one or more processors of the switch that are dedicated to cryptographic processing if a destination port of the packet indicates a secure transport protocol, and to a second one or more processors of the switch that are not dedicated to cryptographic processing if the destination port does not indicate a secure transport protocol. If a source of the packet is an authenticated user, the packet is forwarded via an output port of the switch, based on the associative store. If the source is an unauthenticated user, the packet is forwarded to the first one or more processors if the destination port indicates a secure transport protocol, and to the second one or more processors if the destination port does not indicate a secure transport protocol.Type: GrantFiled: April 27, 2012Date of Patent: August 5, 2014Assignee: Foundry Networks, LLC.Inventors: Yan-Zhe Wang, Sean Hou, Sridhar Devarapalli, Louis Yun

Publication number: 20040028047Abstract: Methods and apparatus, including computer program products, implement techniques for processing data packets in a computer network. A packet filter engine is configured to process data packets at wire-speed based on or more user defined packet policies. A received data packet is examined to determine if there is a match between the data packet and one or more packet policies. If no matching packet policies are found, the packet is routed. If a matching packet policy is found, the data packet is processed based on the policy action fields of the matching policy.Type: ApplicationFiled: May 22, 2003Publication date: February 12, 2004Inventors: Sean Hou, William R. Ge, Daniel Yin Yung Ching, Keith M. Andrews, Christopher H. Claudatos, Magnus B. Hansen
