20140269380 | METHOD AND SYSTEM FOR ACTIVE FABRIC MANAGEMENT USING UNICAST REACHABILITY MONITORING - A method for active network fabric management. The method includes receiving a probe packet by a termination beacon, where the probe packet is associated with a stream, the stream is identified using an origin beacon identification (ID) for an origin beacon, a stream source IP address, a stream destination IP address, an L2 origin interface, and a TTL value or an IP Hop value. The method further includes generating, after receiving the probe packet and after the expiration of a probe rate request (PRR) refresh timer, a rate control packet (RCP) by the termination beacon where the RCP includes a PRR for the stream, and sending the RCP to the origin beacon using an origin beacon IP address, where the origin beacon IP address is different than the stream source IP address. | 09-18-2014 |
20140337467 | METHOD AND SYSTEM FOR USING JSON WITH A CLI FOR MANAGING NETWORK DEVICES - A method for executing a command line interface (CLI) command by receiving a hyper text transport protocol (HTTP) comprising the CLI command from a controller, extracting the CLI command from the HTTP request, and executing, by a network device, the CLI command to generate a populated model comprising results generated from executing the CLI command. The method also executes the CLI command by converting the populated model into a JSON format using a JSON engine to obtain a JSON result; encapsulating the JSON result in a JSON Remote Procedure Call (RPC), and transmitting the JSON RPC as a HTTP response to the controller. | 11-13-2014 |
20150010001 | METHOD AND SYSTEM FOR OVERLAY ROUTING WITH VXLAN - In general, embodiments of the invention relate to routing packets between hosts or virtual machines in different layer 2 domains. More specifically, embodiments of the invention relate to using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between hosts or virtual machines in different layer 2 domains to communication. The overlay routing mechanisms may include direct routing, indirect routing, naked routing, or a combination thereof (e.g., hybrid routing). | 01-08-2015 |
20150010002 | METHOD AND SYSTEM FOR OVERLAY ROUTING WITH VXLAN ON BARE METAL SERVERS - In general, embodiments of the invention relate to routing packets between servers in different layer 2 domains. More specifically, embodiments of the invention relate to using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between servers in different layer 2 domains to communication. The overlay routing mechanisms may include direct routing, indirect routing, naked routing, or a combination thereof (e.g., hybrid routing). | 01-08-2015 |
20150058470 | SYSTEM AND METHOD FOR SHARING VXLAN TABLE INFORMATION WITH A NETWORK CONTROLLER - A method and system for sharing host entries between virtual tunnel endpoints (VTEPs). The method includes making a first determination that an NLHE is present in a locally learned host entry table on a VTEP where the NHLE is associated with a first timestamp, and making a second determination that a first entry corresponding to the NHLE is present in a Host-Specific Portion of Global Host Entry Table (HSPT) on the VTEP, where the first entry is associated with a second timestamp. Based on the second determination, making a third determination, using the timestamps, that the NHLE is more recent than the first entry and based on the third determination updating an active forwarding table on the first VTEP to include a second entry corresponding to the NHLE and to remove the first entry and sending the NHLE to a VXLAN controller operatively connected to the VTEP. | 02-26-2015 |
20150200808 | METHOD AND SYSTEM FOR VIRTUAL MACHINE AWARE POLICY MANAGEMENT - A method and system for maintaining persistent network policies for a virtual machine (VM) that includes determining a name of the VM executing on a first host connected to a first network device; binding the name of the VM to a network policy for the VM on the first network device; acquiring from VM management software, using the name of the VM, a universally unique identifier (UUID) of the VM; associating the UUID to the network policy on the first network device; applying the network policy for the VM on the first network device; subscribing to receive notifications from the VM management software of changes to the configuration of the VM corresponding to the UUID; receiving notification from the VM management software of a configuration change made to the VM corresponding to the UUID; and updating the network policy of the VM to reflect the configuration change of the VM. | 07-16-2015 |
20150200847 | METHOD AND SYSTEM FOR IMPLEMENTING A NETWORK POLICY USING A VXLAN NETWORK IDENTIFIER - A method and system for applying a network policy in a virtual extensible local area network (VXLAN) environment. The method includes receiving, at a network device, a VXLAN frame that includes a source VXLAN network identifier (VNI). The network device includes a first network policy. The method also includes examining the VXLAN frame to determine the source VNI; obtaining, based on the source VNI, the first network policy; and processing the VXLAN frame based on the application of the first network policy. | 07-16-2015 |
20150200954 | METHOD AND SYSTEM FOR USING VIRTUAL TUNNEL END-POINT REGISTRATION AND VIRTUAL NETWORK IDENTIFIERS TO MANAGE VIRTUAL EXTENSIBLE LOCAL AREA NETWORK ACCESS - A method and system for securing a VXLAN environment, including configuring a default network policy, associated with interfaces of the network device, for dropping all VXLAN frames including a VXLAN attribute; obtaining, by the network device, registered VTEP identifiers; determining, using the registered VTEP identifiers, that an interface of the network device is operatively connected to a registered VTEP associated with a registered VTEP identifier; disassociating the default network policy from the interface based on the determination; receiving, at the interface, a frame; performing a first verification that the frame is a VXLAN frame by examining the frame to determine that the frame includes the VXLAN attribute; performing a second verification to determine that the VXLAN frame includes a registered VTEP identifier; allowing, based on the first verification and the second verification, the network device to process the VXLAN frame; and processing the VXLAN frame. | 07-16-2015 |
