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: 11005682Abstract: Network policies can be used to optimize the flow of network traffic between virtual machines (VMs) in a hybrid cloud environment. In an example embodiment, one or more policies can drive a virtual switch controller, a hybrid cloud manager, a hypervisor manager, a virtual switch, or other orchestrator to create one or more direct tunnels that can be utilized by a respective pair of VMs to bypass the virtual switch and enable direct communication between the VMs. The virtual switch can send the VMs network and security policies to ensure that these policies are enforced. The VMs can exchange security credentials in order to establish the direct tunnel. The direct tunnel can be used by the VMs to bypass the virtual switch and allow the VMs to communicate with each other directly.Type: GrantFiled: October 6, 2015Date of Patent: May 11, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: David W.

Patent number: 10462072Abstract: According to one aspect, a method includes an Intercloud Fabric Switch (ICS) included in a public cloud and an ICS cluster obtaining a packet, and determining if the packet is obtained from a site-to-site link that links the ICS to an enterprise datacenter. If the packet is obtained from the site-to-site link, it is determined whether the packet is an unknown unicast packet. If the packet is an unknown unicast packet, the packet is dropped, and if not, the packet is provided to an access link that links the ICS to a virtual machine. If the packet is not obtained from the site-to-site link, it is determined whether the packet is obtained from an inter-ICS link that allows the ICS to communicate with the ICS cluster. If the packet is obtained from the inter-ICS link, the packet is dropped if it is an unknown unicast packet.Type: GrantFiled: March 15, 2018Date of Patent: October 29, 2019Assignee: CISCO TECHNOLOGY, INC.Inventors: David W.

Patent number: 10237379Abstract: An example method for distributed service chaining is provided and includes receiving a packet belonging to a service chain in a distributed virtual switch (DVS) network environment, the packet includes a network service header (NSH) indicating a service path identifier identifying the service chain. The packet is provided to a virtual Ethernet module (VEM) connected to an agentless service node (SN) providing an edge service such as a server load balancer (SLB). The VEM associates a service path identifier corresponding to the service chain with a local identifier such as a virtual local area network (VLAN). The agentless SN returns the packet to the VEM for forwarding on the VLAN. Because the VLAN corresponds exactly to the service path and service chain, the packet is forwarded directly to the next node in the service chain. This can enable agentless SNs to efficiently provide a service chain for network traffic.Type: GrantFiled: September 21, 2017Date of Patent: March 19, 2019Assignee: Cisco Technology, Inc.Inventors: Surendra M.

Patent number: 10158561Abstract: Techniques are provided to decouple service chain structure from the underlying network forwarding state and allow for data plane learning of service chain forwarding requirements and any association between services function state requirements and the forward and reverse forwarding paths for a service chain. In a network comprising a plurality of network nodes each configured to apply a service function to traffic that passes through the respective network node, a packet is received at a network node. When the network node determines that the service function it applies is stateful, it updates context information in a network service header of the packet to indicate that the service function applied at the network node is stateful and that traffic for a reverse path matching the classification criteria is to be returned to the network node.Type: GrantFiled: December 11, 2015Date of Patent: December 18, 2018Assignee: Cisco Technology, Inc.Inventors: James Guichard, Paul Quinn, David Ward, Surendra Kumar, Yavindra Yadav, Michael R.
