Patent number: 12192179Abstract: The present disclosure is directed to systems and methods for dynamic firewall discovery on a service plane. The method includes the steps of identifying a source data packet for transmission from a source machine at a source site to a destination machine at a destination site, wherein the source data packet corresponds to a request for connection between the source machine and the destination machine over a WAN, inspecting the source data packet at a first firewall associated with the source site, marking the source data packet with a marker to indicate inspection by the first firewall, transmitting the marked source data packet to the destination site, determining at the destination site that the source data packet has been inspected based on the marker, and forwarding the source data packet to the destination machine at the destination site, without inspection of the source data packet by a second firewall associated with the destination site.Type: GrantFiled: August 4, 2022Date of Patent: January 7, 2025Assignee: CISCO TECHNOLOGY, INC.Inventors: Balaji Sundararajan, Venkatesh Gota B R, Sireesha Yeruva, Chandramouli Balasubramanian, Anand Oswal

Patent number: 12052135Abstract: An enterprise controller of an enterprise network sends to a service gateway of a service provider network a request for network slice information about network slices provisioned on a data plane of the service provider network. Responsive to the sending, the enterprise controller receives from the service gateway the network slice information including identifiers of and properties associated with the network slices. Responsive to receiving a request for the network slice information from a network device at a border of a forwarding plane of the enterprise network, the enterprise controller sends the network slice information to the network device to cause the network device to perform configuring network traffic in the forwarding plane with identifiers of ones of the network slices that match the network traffic, and to perform forwarding the network traffic configured with the identifiers to the data plane of the service provider network.Type: GrantFiled: June 2, 2021Date of Patent: July 30, 2024Assignee: CISCO TECHNOLOGY, INC.Inventors: Oliver James Bull, Rex Emmanuel Fernando, Anand Oswal, Kausik Majumdar, Darren Russell Dukes, Sanjay Kumar Hooda

Patent number: 12003348Abstract: Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to an identifier and tag.Type: GrantFiled: February 4, 2022Date of Patent: June 4, 2024Assignee: Cisco Technology, Inc.Inventors: Anand Oswal, Muninder S.

Patent number: 11870755Abstract: Systems and methods provide for provisioning a dynamic intent-based firewall. A network controller can generate a master route table for network segments reachable from edge network devices managed by the controller. The controller can receive zone definition information mapping the network segments into zones and Zone-based Firewall (ZFW) policies to apply to traffic between a source and destination zone specified by each ZFW policy. The controller can evaluate a ZFW policy to determine first edge network devices that can reach first network segments mapped to the source zone specified by the ZFW policy, second edge network devices that can reach second network segments mapped to the destination zone specified by the ZFW policy, and routing information (from the route table) between the first network segments, the first and second edge network devices, and the second network segments. The controller can transmit the routing information to the edge network devices.Type: GrantFiled: October 26, 2021Date of Patent: January 9, 2024Assignee: Cisco Technology, Inc.Inventors: Vamsidhar Valluri, Saravanan Radhakrishnan, Anand Oswal, Vinay Prabhu, Sarah Adelaide Evans, Suraj Rangaswamy
