Publication number: 20240089340Abstract: A cache management subsystem (CMS) for a network having network gateways logically organized into network gateway (NG) subsets, each NG subset comprising redundant network gateways and each network gateway comprising a local cache configured to store cache entries corresponding to information requests from network users. The subsystem includes (i) a cache manager configured to synchronize certain cache entries between the network gateways of an NG subset and (ii) a CMS cache configured to store, for the NG subset, other cache entries that are not synchronized between the network gateways of the NG subset. In certain implementations, the cache manager synchronizes within NG subsets recent cache entries having relatively frequent hits and the CMS cache stores recent cache entries having relatively infrequent hits, thereby increasing efficiencies if and when a redundant network gateway handles requests for a failed network gateway.Type: ApplicationFiled: September 8, 2022Publication date: March 14, 2024Applicant: Nokia Solutions and Networks OyInventor: Shailesh Prabhu

Patent number: 11929925Abstract: A router encapsulates a payload of a packet in a generic routing encapsulation (GRE) header that defines a connectionless GRE tunnel. The router also encapsulates the payload and the GRE header in one or more reliable transport headers associated with a connection formed using a reliable transport layer. The router conveys the packet via the connectionless GRE tunnel over the reliable transport layer. In some cases, the GRE header is a network virtualization using GRE (NVGRE) header that allows multiple NVGRE overlays to be multiplexed onto a single IP underlay tunnel. The reliable transport layer can be implemented as Transmission Control Protocol (TCP) layer, a QUIC protocol, a Stream Control Transmission Protocol (SCTP) or a QUIC protocol to establish a set of multiplexed sub-connections or streams over a single connection between two endpoints of the tunnel, or a transport layer security (TLS) cryptographic protocol.Type: GrantFiled: December 16, 2020Date of Patent: March 12, 2024Assignee: Nokia Solutions and Networks OyInventor: Pranjal Kumar Dutta

Patent number: 11916586Abstract: A method comprises capturing a first signal from a first radio chain, and dividing samples of the first signal into a first set of sub-vectors. A second signal is captured from a second radio chain. Samples of the second signal are divided into a second set of sub-vectors according to the determined mapping pattern. A gain difference and phase difference between each sub-vector of the first set and a sub-vector of the second set are estimated, acquiring gain differences and phase differences of the first signal and the second signal. The sub-vector level gain differences are combined to acquire a gain difference between the first signal and the second signal. The sub-vector-level phase differences are combined to acquire a phase difference between the first signal and the second signal. One of the first radio chain and the second radio chain are configured to reduce the gain difference and phase difference.Type: GrantFiled: March 16, 2023Date of Patent: February 27, 2024Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventor: Mehdi Alijan

Patent number: 11909716Abstract: Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.Type: GrantFiled: December 8, 2022Date of Patent: February 20, 2024Assignee: Nokia Solutions and Networks OyInventors: Randeep Bhatia, Steven Benno, Fang Hao, Yu Mi, T V Lakshman

Patent number: 11909656Abstract: A CPU implements a virtual network function (VNF) associated with flow processing and can offload at least some of the flow processing to a hardware accelerator. A module (e.g., TOR switch), external to the software-based processor and the hardware accelerator, examines packet flows and determines (e.g., using a top-K elephant-flow-detection algorithm) which ones are more suitable for offloading from the software-based processor to the hardware accelerator than others. The external module communicates the relative suitability for offloading to the CPU using packet tags or out-of-band messaging, and the CPU uses the relative suitability to determine which flows to offload or onload. In some implementations, the CPU can instruct the external module to change the value of K used in the algorithm.Type: GrantFiled: January 17, 2023Date of Patent: February 20, 2024Assignee: Nokia Solutions and Networks OyInventors: Hyunseok Chang, Sarit Mukherjee, Limin Wang
