Publication number: 20240129185Abstract: A secure private network connectivity system (SNCS) within a cloud service provider infrastructure (CSPI) is described that provides secure private network connectivity between external resources residing in a customer's on-premise environment and the customer's resources residing in the cloud. The SNCS provides secure private bi-directional network connectivity between external resources residing in a customer's external site representation and resources and services residing in the customer's VCN in the cloud without a user (e.g., an administrator) of the enterprise having to explicitly configure the external resources, advertise routes or set up site-to-site network connectivity.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Applicant: Oracle International CorporationInventors: Shruti Nitin Shetye, Soumya Kailasa, Jesus Velazquez Reyes, Lucas Michael Kreger-Stickles, Abhiman Yashpala Karkera, Dhwanish Pramthesh Shah, Guanhong Pei, Clayton Matthew Magouyrk, Paul James Cainkar

Publication number: 20230396579Abstract: Techniques for providing, to a resource on a private network of a service provider, access to a resource on a private network of a customer. Service to customer (S2C) resources deployed on a cloud infrastructure to facilitate the access. Whereas IP address ranges may overlap between private networks and/or private IP addresses may be used in one or more of the private networks, the S2C resources enable the data exchange between the private networks. For example, the S2C resources translate between IP addresses such that data within each private network uses IP addresses that can be properly processed by the private network.Type: ApplicationFiled: August 18, 2023Publication date: December 7, 2023Applicant: Oracle International CorporationInventors: Shane Baker, Richendra Khanna, Leonard Thomas Tracy, Guanhong Pei

Publication number: 20230396539Abstract: Techniques are disclosed for providing high performant packets processing capabilities in a virtualized cloud environment that enhance the scalability and high availability of the packets processing infrastructure. In certain embodiments disclosed herein, the VNICs functionality performed by network virtualization devices (NVDs) is offloaded from the NVDs to a fleet of computers, referred to as VNIC-as-a-Service System (or VNICaaS system). VNICaaS system is configured to provide Virtual Network Interface Cards (VNICs)-related functionality or service for multiple compute instances belonging to multiple tenants or customers of the CSPI. The VNICaaS system is capable of hosting multiple VNICs to process and transmit traffic in a distributed virtualized cloud networks environment. A single VNIC executed by the VNICaaS system can be used to process packets received from multiple compute instances.Type: ApplicationFiled: August 14, 2023Publication date: December 7, 2023Applicant: Oracle International CorporationInventors: Leonard Thomas Tracy, Raman Kumar Sonkhla, Guanhong Pei

Patent number: 11736558Abstract: A secure private network connectivity system (SNCS) within a cloud service provider infrastructure (CSPI) is described that provides secure private network connectivity between external resources residing in a customer's on-premise environment and the customer's resources residing in the cloud. Secure access to an external resource is enabled by the SNCS by creating an external resource representation (i.e., a computing instance) for the external resource in the customer's virtual cloud network (VCN) in the cloud and creating a virtual network interface card for the external resource representation. Using the SNCS, the customer can securely access the external resource residing in their on-premise network from within their VCN by connecting to the virtual IP address assigned to the VNIC without requiring to set up elaborate site-to-site networking, without making changes to their on-premise routing configuration or without making any changes to the configuration of the external resource.Type: GrantFiled: October 29, 2021Date of Patent: August 22, 2023Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Lucas Michael Kreger-Stickles, Abhiman Yashpala Karkera, Dhwanish Pramthesh Shah, Guanhong Pei, Clayton Matthew Magouyrk, Paul James Cainkar

Patent number: 8284788Abstract: A method and apparatus is disclosed herein for scalable routing with greedy embedding. In one embodiment, the method comprises storing log(n) coordinates in a routing table, where n is the number of nodes in a network, and further wherein the log(n) coordinates are generated by constructing a greedy embedding that embeds a graph topology depicting connections between n nodes of a network into a geometric space so as to use greedy forwarding by generating a spanning tree out of a connection graph representing the connections between the n nodes of the network, decomposing the tree into at most n branches, assigning a set of geometric coordinates to vertices in the tree in an n-dimensional space, and projecting the set of geometric coordinates onto a k-dimensional space, where k is less than n, to create the log(n) coordinates; and routing packets via nodes of the network using the log(n) coordinates in the routing table.Type: GrantFiled: July 30, 2009Date of Patent: October 9, 2012Assignee: NTT DoCoMo, Inc.Inventors: Cedric Westphal, Guanhong Pei
