Patent number: 10237182Abstract: The present disclosure describes several key features of an agent deployable on a service appliance: agent architecture/design, transport and channel abstractions of the agent, new message definition components, channel switching (e.g., platform independent processing), Channel state machine, platform dependent hooks (e.g., memory, timers), Service key data store, and Secure channel infrastructure. Many of these features alleviate the vendor of the service appliance from having to provide the features. The features and standardization thereof enable the system to be more robust (and increases code quality). Speed of integration is decreased while the risk of integration issues is also decreased. Updates to the agent can be deployed in a controlled and efficient manner. Furthermore, the agent can ensure security between a switch and the agent.Type: GrantFiled: January 12, 2018Date of Patent: March 19, 2019Assignee: Cisco Technology, Inc.Inventors: Samar Sharma, Mitali Parthasarathy, Avni Baveja, Ashish Purushottam Attarde, Biju Mathews Mammen

Patent number: 9935882Abstract: In one embodiment a forwarding policy from a first network node coupled to a network element is received. The forwarding policy specifies an address of a second network node coupled to the network element. A plurality of ports of the network element are identified, wherein the second network node is accessible from the network element through each of the plurality of ports. The forwarding policy is applied to the plurality of ports of the network element. Network traffic received at a port of the plurality of ports from the second network node is forwarded to the first network node.Type: GrantFiled: August 25, 2015Date of Patent: April 3, 2018Assignee: Cisco Technology, Inc.Inventors: Avni Baveja, Samar Sharma, Mitali Parthasarathy, Ashish Purushottam Attarde
