CPC Code(s): H04L9/3236
Abstract: techniques for using network address translation (nat), mobile internet protocol (mip), and/or other techniques in conjunction with domain name system (dns) to anonymize server-side addresses in data communications and verify an authenticity of a client device attempting to use a virtual ip (vip) address. rather than having dns provide a client device with an ip address of an endpoint device, such as a server, the dns instead returns a vip address that is mapped to the client device and the endpoint device. the client device may then communicate data packets to the server using the vip address as the destination address, and a virtual network service that works in conjunction with dns can verify an authenticity of the client device and convert the vip address to the actual ip address of the server using nat and forward the data packet onto the server.

CPC Code(s): H04L45/38
Abstract: techniques for detecting duplicate data flows. a data packet of a data flow is received by computer hardware the data packet having a first five tuple, an ingress interface and a vlan tag. data is sent to a central processing unit. the central processing unit installs policy tiles into a policy tile database of the computer hardware, the policy tiles including the first five tuple, the first ingress interface and the first vlan tag. a second data packet is received and compared with the policy tiles in the policy tile database. if the second data packet has the same five tuple as the first data packet but has either a different ingress interface or a different vlan tag, then the second data packet is determined to be a duplicate of the first data flow and is dropped.

IPC Code(s): H04L45/76
CPC Code(s): H04L45/76
Abstract: systems and methods are provided for re-balancing and healing of an sd-wan in an unbalanced state and/or experiencing one or more failure states. in response to a request to connect to a new controller resulting from omp load shedding from a first controller, the system can identify other controllers capable of handling the load requirements of the edge router. the system can incorporate the controller group preference of the edge router and select a second controller based on the identified other controllers and within the preferred controller group. if not possible, the system can temporarily assign the edge router to non-preferred controller groups and move them back to controllers in the preferred controller group once it becomes viable. the system further enhances omp graceful restart (gr) logic to incorporate the load shedding effect and avoid unnecessary route retention that gr entails.

IPC Code(s): H04L61/2503, H04L9/40, H04L61/4511
CPC Code(s): H04L61/2503
Abstract: techniques for using prefix address translation (pat), mobile internet protocol (mip), and/or other techniques to anonymize server-side addresses in data communications. rather than allowing a server and/or endpoint have visibility of a client ip address of a client device accessing the server and/or endpoint, a virtual network service instead returns a pat ip address that is mapped to the client device and/or the endpoint device. in this way, ip addresses of clients devices are obfuscated by the virtual network. the client device may then communicate data packets to the server and/or endpoint using the pat ip address as the source address, and the virtual network service that works in conjunction with the server and/or endpoints can convert the pat ip address to the actual ip address of the client for return packets using pat and forward the return packet onto the client device.

IPC Code(s): H04L61/5007, H04L61/2503
CPC Code(s): H04L61/5007
Abstract: techniques for using home addresses, mobile internet protocol (mip), and/or other techniques in conjunction with domain name system (dns) to obfuscate server-side addresses in data communications. rather than having dns provide a client device with an ip address of an endpoint device, such as a server, the dns instead returns a home address that is mapped to the client device and at least one server ip address of the endpoint device. in this way, ip addresses of servers are obfuscated by a network mapping of the home addresses and the server ip addresses. the client device may then communicate data packets to the server using the home addresses as the destination address, and a virtual network service that works in conjunction with dns can encapsulate the data packet with the server ip addresses and forward the data packet onto the server.

IPC Code(s): H04L61/5007, H04L9/40, H04L61/2503, H04L61/4511
CPC Code(s): H04L61/5007
Abstract: techniques for varying locations of virtual networks associated with endpoints using network address translation (nat), mobile internet protocol (mip), and/or other techniques in conjunction with domain name system (dns). rather than having dns provide a client device with an ip address of an endpoint device, such as a server, the dns instead returns a virtual ip (vip) address that is mapped to the client device and the endpoint device. the vip address may be selected based on a number of factors (e.g., power usage, privacy requirements, virtual distances, etc.). in this way, ip addresses of servers are obfuscated by a virtual network of vip addresses that can be periodically rotated and/or load balanced. the client device may then communicate data packets to the server using the vip address as the destination address, and a virtual network service that works in conjunction with dns can convert the vip address to the actual ip address of the server using nat and forward the data packet onto the server.

CPC Code(s): H04L63/0876
Abstract: this disclosure describes techniques for enforcing conditional access to network services. in an example method, a first computing device detects a second device operating in a per-flow authorization mode. the first device receives a first request from a second computing device to communicate with a third computing device using a first network flow and determines that the first flow is authorized (e.g., because of an active past authentication and/or the third device's authentication exemption). data associated with the first request is transmitted to the third device. the first device then receives a second request to communicate with a fourth computing device using a second network flow and determines that the second flow is not authorized (e.g., because it is not associated with an active past authentication and/or the fourth device is not exempt from authentication). data associated with the second request is not transmitted to the fourth device.
