Aalyria

aid: aalyria
name: Aalyria
description: 'Aalyria Technologies builds software and hardware for operating resilient, high-throughput networks in motion
  across space, air, land and sea. Its flagship platform, Spacetime, is a temporospatial software-defined networking (SDN)
  system that models the time-dynamic position and orientation of satellites, aircraft, ships and ground stations, then continuously
  plans, schedules and steers the links between them. Spacetime is programmable through three open, Apache-2.0 licensed gRPC/Protocol
  Buffers APIs published at github.com/aalyria/api: a Northbound Interface (NBI) for defining and orchestrating the network
  model and provisioning traffic-engineering policies, a Southbound Interface (SBI, also called CDPI) through which participating
  devices receive schedule updates and push telemetry, and a Federation (East-West) API through which peer network operators
  request and supply interconnections and capacity. Aalyria also produces Tightbeam, a free-space optical communications system.
  The company was spun out of Alphabet in 2022, carrying technology developed for Project Loon and Taara.'

  name: Spacetime Northbound Interface (NBI)
  description: The Northbound Interface allows humans or applications to define and orchestrate a Spacetime network. It carries
    the Model API (NMTS entities and relationships describing platforms, antennas, interfaces and their time-dynamic position
    and orientation), the Provisioning API (traffic-engineering policies, links, downtimes, protection and disjoint association
    groups, geographic regions), the Solution API (computed beams and candidate paths), the Simulation API (scenarios and
    analyses), Permissions and Audit Logs. It is a gRPC API defined in Protocol Buffers and served per customer instance over
    subdomain-resolved endpoints such as model-v1.$DOMAIN.

  name: Spacetime Southbound Interface (SBI / CDPI)
  description: The Southbound Interface, also called the Control to Data-plane Interface (CDPI), is the collection of gRPC
    services through which devices participating in a Spacetime network communicate with the controller. The Scheduling service
    is a bidirectional stream over which an agent receives schedule updates — steering antenna beams to establish new links,
    configuring RF parameters, applying flow and radio control — and returns responses; the Telemetry service pushes metrics
    and observations back to Spacetime. A reference Go implementation of an SBI agent ships in the same repository.

  name: Spacetime Federation API (East-West Interface)
  description: The Federation API, or East-West Interface, allows peer networks to request and to supply network resources
    and interconnections between partners' networks. It carries the Interconnect service, through which operators negotiate
    and manage interconnection points and service requests between distinct networks, and the Transponder service, through
    which capacity on a transponded payload is advertised, requested and scheduled. This facilitates dynamic, real-time inter-network
    connections so operators can supplement gaps in coverage or advertise unused capacity.

- aid: aalyria:spacetime-status
  name: Spacetime Status API
  description: The Status API is a small operational gRPC service exposed by every Spacetime instance. GetVersion returns
    the semantic version of the running Spacetime build, and GetMetrics returns instance insight metrics encoded in the standard
    OpenTelemetry metrics protobuf format — platform-type counts and inbound/outbound scheduling message counts. It is reachable
    through the nbictl command line tool as status-v1 and is the surface used to confirm connectivity and credentials against
    a new deployment.
