Patent number: 12363115Abstract: In one embodiment, a request may be received from a first cloud network of a hybrid cloud environment to transmit data to a second cloud network of the hybrid cloud environment, wherein the request can include a security profile related to the data. The security profile may be automatically analyzed to determine access permissions related to the data. Based at least in part on the access permissions, data can be allowed to access to the second cloud network.Type: GrantFiled: December 20, 2021Date of Patent: July 15, 2025Assignee: Cisco Technology, Inc.Inventors: Mauricio Arregoces, Nagaraj Bagepalli, Subramanian Chandrasekaran

Patent number: 11604658Abstract: Many hybrid cloud topologies require virtual machines in a public cloud to use a router in a private cloud, even when the virtual machine is transmitting to another virtual machine in the public cloud. Routing data through an enterprise router on the private cloud via the internet is generally inefficient. This problem can be overcome by placing a router within the public cloud that mirrors much of the routing functionality of the enterprise router. A switch configured to intercept address resolution protocol (ARP) request for the enterprise router's address and fabricate a response using the MAC address of the router in the public cloud.Type: GrantFiled: June 11, 2021Date of Patent: March 14, 2023Assignee: Cisco Technology, Inc.Inventors: David W.

Patent number: 9965317Abstract: A sense of location is provided for distributed virtual switch components into the service provisioning scheme to reduce latency observed in conducting policy evaluations across a network in a hybrid cloud environment. A management application in a first virtual network subscribes to virtual network services provided by a first virtual service node in the first virtual network. A second virtual network receives the subscription to the virtual network services and starts a virtual switch that switches network traffic for one or more virtual machines in the second virtual network that are configured to extend services provided by the first virtual network into the second virtual network. The second virtual network starts a second virtual service node in the second virtual network that provides network traffic services for the one or more virtual machines.Type: GrantFiled: March 22, 2017Date of Patent: May 8, 2018Assignee: Cisco Technology, Inc.Inventors: David Chang, Abhijit Patra, Nagaraj Bagepalli, Murali Anantha

Patent number: 9906496Abstract: Techniques are provided for implementing a zone-based firewall policy. At a virtual network device, information is defined and stored that represents a security management zone for a virtual firewall policy comprising one or more common attributes of applications associated with the security zone. Information representing a firewall rule for the security zone is defined and comprises first conditions for matching common attributes of applications associated with the security zone and an action to be performed on application traffic. Parameters associated with the application traffic are received that are associated with properly provisioned virtual machines. A determination is made whether the application traffic parameters satisfy the conditions of the firewall rule and in response to determining that the conditions are satisfied, the action is performed.Type: GrantFiled: September 20, 2016Date of Patent: February 27, 2018Assignee: Cisco Technology, Inc.Inventors: David Chang, Abhijit Patra, Nagaraj Bagepalli, Rajesh Kumar Sethuraghavan

Patent number: 9491201Abstract: A highly scalable application network appliance is described herein. According to one embodiment, a network element includes a switch fabric, a first service module coupled to the switch fabric, and a second service module coupled to the first service module over the switch fabric. In response to packets of a network transaction received from a client over a first network to access a server of a data center having multiple servers over a second network, the first service module is configured to perform a first portion of OSI (open system interconnection) compatible layers of network processes on the packets while the second service module is configured to perform a second portion of the OSI compatible layers of network processes on the packets. The first portion includes at least one OSI compatible layer that is not included in the second portion. Other methods and apparatuses are also describe.Type: GrantFiled: June 22, 2015Date of Patent: November 8, 2016Assignee: Cisco Technology, Inc.Inventors: Nagaraj Bagepalli, Prashant Gandhi, Abhijit Patra, Kirti Prabhu, Anant Thakar
