Abstract: An indication of a set of premises between which network traffic is to be routed via a private fiber backbone of a provider network is obtained. Respective virtual routers are configured for a first premise and a second premise, and connectivity is established between the virtual routers and routing information sources at the premises. Contents of at least one network packet originating at the first premise are transmitted to the second premise via the private fiber backbone using routing information obtained at the virtual routers from the routing information source at the second premise.

Abstract: A network change verification (NCV) system is disclosed for checking whether a proposed configuration change on a network alters the way that the network controls recently observed network flows. In embodiments, the system builds an observed flow control model (OFCM) from logs of recent flows observed in the network. The OFCM, which may be periodically updated based on newly observed flows, provides a compact representation of how individual network flows were ostensibly controlled by the network. When a proposed configuration change is received, the system analyzes the change against the OFCM to check whether the change will alter how the network controls recently observed flows. If so, the proposed change is blocked, and an alert is generated identifying flows that are affected by the change. The NCV system thus prevents network operators from accidentally making changes on the network that will materially alter the behavior of the network.

Abstract: Systems and methods are provided for management of network segments that cross geographic regions and/or other types of network divisions in a cloud-based network environment. A cloud-based network provider's geographically-dispersed network infrastructure may serve as the core of a client's private wide area network, and the client may define isolated segments to which other networks (virtual private clouds, virtual private networks, etc.) may be attached. The various segments may remain logically isolated from each other even when implemented across some or all of the same regions—and using the same physical and/or virtual routing components—as other segments of the same client and/or other clients.

Abstract: Systems and methods are provided for obtaining policy data associated with a private network implemented at least partly within a cloud provider network; establishing, based on the policy data, a first segment within the private network, wherein in a first geographic region of the cloud provider network, traffic associated with the first segment is isolated from traffic associated with a second segment of the private network, and wherein in a second geographic region of the cloud provider network, traffic associated with the first segment is isolated from traffic associated with a third segment of the private network; obtaining metadata indicating an isolated network of the cloud provider network is associated with the first segment; and enabling the isolated network to communicate, over the first segment, across the first geographic region and the second geographic region.

Abstract: Systems and methods are provided for evaluation of communication paths through networks to determine whether communication is permitted across one or more internal network boundaries. The analysis may be used to determine whether a node in one isolated network (e.g., VPC, VPN, client on-premise network, etc.) is able to communicate with a node in another isolated network across region and/or segment boundaries. The automated analysis can allow users (e.g., network administrators) to see what high-level policies (e.g., Cloud WAN policies written in a declarative language) are interfering with or permitting communication between the nodes.

Abstract: Systems and methods are provided for management of network segments that cross geographic regions and/or other types of network divisions in a cloud-based network environment. Gateway may manage traffic across regions using routing metadata that includes a segment identifier. The gateways may also signal their routes across regions based on segment data, and implement the signaled routes using segment-based routing policies. Route selection may be performed using optimization data.

Abstract: A pair of virtual routers is configured. In response to programmatic requests, dynamic transfer of routing information between the routers in accordance with configuration settings indicated by a client is enabled. The routing information is associated with a set of isolated networks to which the virtual routers are attached. A network packet originating at an address in a first isolated network is transmitted to an address in a second isolated network using a route determined from routing information transmitted between the virtual routers according to the configuration settings.
