Patent number: 9049047Abstract: Multicast capability in a virtual private LAN service (VPLS) is provided in a provider IP/MPLS infrastructure without headend replications by encapsulating a customer data packet to use an established multicast protocol, such as IP multicast. In one example, the customer data packet is encapsulated by an IP header having an IP multicast group address and an Ethernet header. In one implementation, a DNS type mechanism is provided to distribute the IP multicast addresses for VPLS use. Such IP multicast group address can be set aside from an administratively scoped address range. An efficient IP routing algorithm running on the provider's network provides an efficient distribution tree for routing IP-encapsulated customer packet for the VPLS.Type: GrantFiled: October 21, 2011Date of Patent: June 2, 2015Assignee: Foundry Networks, LLCInventors: Rajkumar Jalan, Louis Yun, Ivy Pei-Shan Hsu

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
