Abstract: embodiments herein describe a psr that includes a rotator with two layers that are separated by a dielectric layer. a first layer of the rotator includes a first waveguide formed from a lower refractive index material (e.g., sin) while a second layer of the rotator includes a second waveguide formed from a higher refractive index material (e.g., si). an optical signal, which can include two optical modes (e.g., te and tm modes), is then introduced into the first layer where the tm mode is rotated. at the end of the rotator, the first waveguide (which is the same waveguide that received the optical signal) includes the optical signal which is now in the same optical mode. that is, one of the optical modes is rotated so that the light is the same type of optical mode (e.g., te).

Abstract: techniques and architecture are described for initializing, reviewing/approving, and deploying changes within a network. each change is associated with a particular change ticket. when a change needs to be rolled back, the original change ticket may be analyzed to determine what actions need to be performed to roll back the change. a plan of the needed actions may then be presented to a reviewer in a rollback ticket. the original change ticket may be cancelled and a new ticket, e.g., the rollback ticket, may be prepared that includes the plan for the rollback, e.g., the one or more actions needed to roll back the initial change. in configurations, a change ticket may include multiple changes and thus, for rollback, either all the changes associated with the change ticket may be rolled back or only the last change or action that was initially made may be rolled back.

Abstract: a system and method are provided for continuous integration, continuous deployment of a network component, such as a software-defined wide area network, a firewall, a router, or a load balancer. the software development lifecycle is achieved without interrupting the data flow of the network by using a multi-dataplane architecture, including a primary dataplane and a shadow dataplane. a packet dispatcher relays ingress data packets to the primary dataplane executing a current version of the network component and the shadow dataplane executing an upgrade to the network component. a control plane agent analyzes/compares the performances of the respective dataplanes for verification testing, and the control plane agent upgrades the network component to the new version upon passing the verification testing. the upgrades is achieved without interruption to the data flow of the network component by gradually transitioning to outputting egress data packets generated using the upgraded version.

Abstract: a system and method are provided for adding in-band metadata with a data flow. the in-band metadata can be based on observations by an extended berkley packet filter (ebpf) of an application running in a datacenter, for example. a processor executes the application to generate data that is encoded in the payloads of packets in a data flow to be transmitted via a network to a destination. the ebpf is also executed on the processor and generates observations of the application (e.g., osi layer 7 observations). metadata is generated based on the observations and encoded into headers of the packets of the data flow. the metadata can then be used at the destination to determine the next processing steps for the data flow (e.g., is the data flow trusted and allowed into another workload).

Abstract: a system and method are provided for routing traffic through a network to ensure load balancing and avoid untrustworthy nodes. based on network data (e.g., telemetry data), a machine learning model generates trust scores, which are used for routing decisions by determining preferred routes from a source to a destination. the trust scores for nodes along a potential route can be combined into a cumulative trust score. the potential route with the lowest cumulative trust score (i.e., most trustworthy) is preferred, when all other factors are equal. traffic is routed along the preferred routes, until their capacity is exceeded. then to achieve load balancing, traffic flows are extended to the next most preferred routes (e.g., the next lowest cumulative trust score), and so forth. when traffic flows include a mix of sensitive and non-sensitive data, the sensitive data is preferentially directed along the most preferred routes.

Abstract: a system and method are provided for continuous integration, continuous deployment of a network component, such as a software-defined wide area network, a firewall, a router, or a load balancer. the network component is tested before deployment by acquiring data flows from a production environment and obtaining an acquired flow table that includes respective entries corresponding to types of data flows that are defined by header information (e.g., 5-tuples or pairs of source and destination addresses, depending at which layer in the osi model the network component operates). first and second flow tables are generated for the first and second versions of the network component by applying simulated traffic (e.g., derived from the acquired data flows) to the respective versions of the network component. a comparison between the first and second flow tables is evaluated to determine whether second version of the network component can be deployed.

Abstract: a system and method are provided for communicating security service context within a network. intermediary nodes located along the path of a data flow apply various security services to the data flow, and keep a record of the security services by generating in-band and out-of-band information. the in-band information is limited, e.g., by the maximum transmission unit (mtu) to short attestations that fit within optional ipv6 extension headers. the out-of-bound information, which is recorded, e.g., in a ledger using an overlay network, provides additional information fully describing the security services. based on the in-band and out-of-band information (e.g., using the attestations to retrieve the additional information from the ledger), the data flow is either allowed or denied entrance to a particular workload. applying the security services and generating the in-band and out-of-band information can be performed using data processing units (dpus) and/or an extended berkley packet filters (ebpfs).
