Publication number: 20240195844Abstract: In an example, systems and methods enable automatic implementation of intent-based security policies in a network system, such as a software-defined wide area network system, in which network segment prefixes for network segments at one or more sites are dynamically learned. A service orchestrator controller translates an intent-based security policy input by a user to a security policy for a first site. The security policy for the first site specifies a segment-specific queryable resource associated with a second site. To implement the security policy, a device associated with the first site queries the segment-specific queryable resource associated with the second site, and updates one or more forwarding tables of the device with the network segment prefixes associated with one or more network segments at the second site received in response to the query. The first site forwards network traffic to the second site based on the updated forwarding tables.Type: ApplicationFiled: February 22, 2024Publication date: June 13, 2024Inventors: Kaushik Dutta Majumdar, FNU Nadeem, Shanmukh Uppuluri

Patent number: 11336482Abstract: Techniques are described for policy driven on-demand tunnel creation and deletion between end points in a software-defined wide area network (SD-WAN) having a hub-and-spoke topology. A software-defined networking (SDN) controller that facilitates cloud-based services of a service provider network that sets up the SD-WAN is configured to determine whether a tunnel between end-points is to be created or deleted based on information indicative of the traffic, such as amount, time, application generating the traffic, and the like, between end-points.Type: GrantFiled: March 29, 2019Date of Patent: May 17, 2022Assignee: Juniper Networks, Inc.Inventors: Sankar Ramamoorthi, Ravi Shekhar, Venkata Rajasekharu Athreyapurapu, Rajeev Gupta, Kaushik Dutta Majumdar, Mohan Kumar A P, Pranav Koushik

Patent number: 11055427Abstract: A cloud security system and method designed to protect users' data in case of accidental leaks in a cloud computing environment. Secured hashing of the names of folders stored on the cloud data storage are generated and persisted using multiple iterations of cryptographic hash functions along with a concatenated random number for each of the folder names, thereby providing protection against vulnerability of the folder names. The proposed system is a dual-layer framework consisting of a control layer and a data layer. The control layer is responsible for cryptographic hashing and persistence of the folder name, hashed name, salt, and iterations in a database. The control layer communicates with the data layer and provides the hashed folder names to persist the user data cloud storage.Type: GrantFiled: February 7, 2019Date of Patent: July 6, 2021Assignee: University of South FloridaInventors: Vivek Kumar Singh, Kaushik Dutta, Balaji Padmanabhan, Shalini Sasidharan

Patent number: 10523560Abstract: Techniques are described for selecting paths in accordance with service level agreements. For example, spoke and hub routers may advertise routes associated with virtual routing and forwarding (VRF) instances mapped to service level agreements (SLAs). A virtual route reflector of an intermediate router may receive route advertisements and may add respective path communities associated with particular links selected based on link state measurements in accordance with the SLAs. The hub or spoke routers may receive the route advertisements including a respective path community and install the selected path as a next-hop for a given SLA. In this way, spoke and hub routers may forward traffic on links that satisfy particular SLAs such that Quality of Experience (QoE) for an application may be restored or improved.Type: GrantFiled: July 28, 2017Date of Patent: December 31, 2019Assignee: Juniper Networks, Inc.Inventors: Nagaraja Manikkar Shenoy, Prasad V, Kaushik Dutta Majumdar
