Enabling virtual workloads using overlay technologies to interoperate with physical network services
Patent number: 9444644Abstract: A solution is provided to enable cloud service provider customers/users to offer physical network services to virtualized workloads that use overlay technologies, such as a Virtual Extensible Local Area Network (VXLAN). For a virtual workload that uses an overlay technology, an identifier is received of a logical network to which the virtual workload connects and a policy for the logical network. Based on the identifier of the logical network and the policy, a gateway is configured to connect traffic for the virtual workload on the logical network to a particular virtual local area network (VLAN) interface of the physical network service equipment on which the policy is configured.Type: GrantFiled: April 21, 2015Date of Patent: September 13, 2016Assignee: Cisco Technology, Inc.Inventors: Saravankumar Rajendran, Ajit Sanzgiri -
Patent number: 9264895Abstract: A detection-based defense to a wireless network. Elements of the infrastructure, e.g., access points or scanning-only access points, detect intruders by detecting spoofed frames, such as from rogue access points. Access points include a signature, such as a message integrity check, with their management frames in a manner that enables neighboring access points to be able to validate the management frames, and to detect spoofed frames. When a neighboring access point receives a management frame, obtains a key for the access point sending the frame, and validates the management frame using the key.Type: GrantFiled: August 12, 2013Date of Patent: February 16, 2016Assignee: Cisco Technology, Inc.Inventors: Mark Krischer, Nancy Cam-Winget, Sheausong Yang, Ajit Sanzgiri, Timothy Olson, Pauline Shuen

Patent number: 8583914Abstract: In one embodiment, a method for providing secure communications using a proxy is provided. The proxy negotiates with a client and a server to determine a session key to use with communications between the client and the proxy and between the proxy and the server. Encrypted data may then be received from the client at the proxy. The proxy can decrypt the encrypted data for processing using the session key. In one embodiment, the decrypted data is not altered. The proxy then sends the encrypted data that was received from the client to the server without re-encrypting the data that was decrypted. Because the proxy did not alter the data in its processing of the decrypted data and the same session key is used between communications for the proxy and the server, the encrypted data stream that was received from the client can be forwarded to the server.Type: GrantFiled: May 25, 2012Date of Patent: November 12, 2013Assignee: Cisco Technology, Inc.Inventors: Etai Lev Ran, Ajit Sanzgiri

The devices perform self-calibration and self-commissioning. The system manager and devices perform ongoing calibration and commissioning. The system manager and devices operate resiliently in case of failure of the system manager, other devices, or software or hardware failures in the devices. The system manager and the devices operate on the collected data to determine usage patterns, and to efficiently manage the plurality of lights and devices.Type: GrantFiled: September 5, 2009Date of Patent: June 4, 2013Assignee: enLighted, Inc.Inventors: Jonathan Golding, Ajit Sanzgiri

Patent number: 8442041Abstract: In one embodiment, ports of a network device are assigned to virtual service domains (VSDs). The ports are coupled to a virtual Ethernet module (VEM) of the network device. Each VSD is associated with one or more virtual service engines (VSEs) in a particular order. Each VSE is configured to apply a particular service to traffic traversing the VSE. Traffic received at a virtual Ethernet module (VEM) of the network device that is destined for a particular VSD, and is received on a port that has not been assigned to the particular VSD, is forwarded to the particular VSD via the one or more VSEs associated with the particular VSD such that the traffic traverses the one or more VSEs in the particular order.Type: GrantFiled: July 25, 2012Date of Patent: May 14, 2013Assignee: Cisco Technology, Inc.Inventors: Srinivas Sardar, Udayakumar Srinivasan, Shankar Ramachandran, Chidambareswaran Raman, Ajit Sanzgiri, Michael R.
