Patent number: 10057084Abstract: The present disclosure is directed towards systems and methods for extending VLANs into the cloud using VXLANs. A method for extending an on-premise network to the cloud is described. A cloud bridge connector (CBC) executing on a device in communication with an on-premise network and a cloud network receives a packet from the on-premise network. The CBC identifies, from the packet, a virtual local area network (VLAN) identifier of the packet. The VLAN identifier identifies a VLAN established on the on-premise network. The CBC determines, via a mapping table, a VXLAN identifier of a VXLAN established on the cloud network to transmit the packet on the cloud network. The device modifies the packet to identify the VXLAN identifier and transmits the modified packet on the cloud network.Type: GrantFiled: October 6, 2015Date of Patent: August 21, 2018Assignee: Citrix Systems, Inc.Inventors: Sharvari Mithyantha, Manohar Singareddy, Sridhar Devarapalli

Patent number: 9411656Abstract: A network device includes a plurality of blades, each having a plurality of CPU cores that process requests received by the network device. Each blade further includes an accumulator circuit. Each accumulator circuit periodically aggregates the local counter values of the CPU cores of the corresponding blade. One accumulator circuit is designated as a master, and the other accumulator circuit(s) are designated as slave(s). The slave accumulator circuits transmit their aggregated local counter values to the master accumulator circuit. The master accumulator circuit aggregates the sets of aggregated local counter values to create a set of global counter values. The master accumulator circuit transmits the global counter values to a management processor (for display), to the CPU cores located on its corresponding blade, and to each of the slave accumulator circuits. Each slave accumulator circuit then transmits the global counter values to the CPU cores located on its corresponding blade.Type: GrantFiled: June 22, 2009Date of Patent: August 9, 2016Assignee: Brocade Communications Systems, Inc.Inventors: Avinash Jindal, Deepak Bansal, Sam Htin Moy, David Cheung, Bing Wang, Mani Kancherla, Sridhar Devarapalli

Patent number: 8856421Abstract: A multi-processor architecture for a network device that includes a plurality of barrel cards, each including: a plurality of processors, a PCIe switch coupled to each of the plurality of processors, and packet processing logic coupled to the PCIe switch. The PCIe switch on each barrel card provides high speed flexible data paths for the transmission of incoming/outgoing packets to/from the processors on the barrel card. An external PCIe switch is commonly coupled to the PCIe switches on the barrel cards, as well as to a management processor, thereby providing high speed connections between processors on separate barrel cards, and between the management processor and the processors on the barrel cards.Type: GrantFiled: December 14, 2012Date of Patent: October 7, 2014Assignee: Brocade Communications Systems, Inc.Inventors: Mehrdad Hamadani, Deepak Bansal, Sam Htin Moy, Steenivasulu Malli, David Cheung, Mani Kancherla, Sridhar Devarapalli

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
