    Abstract: Embodiments of the present invention provide systems, methods, and computer storage media directed to propagating and authenticating border gateway protocol route advertisements. A trusted authority device stores and distributes routing information for various autonomous systems. The trusted authority device also issues and maintains digital certificates that are each assigned to one of the autonomous systems. The digital certificate can be utilized by autonomous systems to verify the authenticity of routing information advertised by another autonomous system. Each autonomous system can employ a routing device that can generate a route advertisement based on routing information received from the trusted authority device. The route advertisement can include a digital signature, a digital certificate, and a time-to-live value, among other things, each of which can be utilized by routing devices of other autonomous systems to determine the authenticity and validity of received routing information.

    Abstract: Techniques are disclosed for scaling an IP address in overlay networks without using load balancers. In certain implementations, an overlay IP address can be attached to multiple compute instances via virtual network interface cards (VNICs) associated with the multiple compute instances. Traffic directed to the multi-attached IP address is distributed across the multiple compute instances. In some other implementations, ECMP techniques in overlay networks are used to scale an overlay IP address. In forwarding tables used for routing packets, the IP address being scaled is associated with multiple next hop paths to multiple network virtualization devices (NVDs) associated with the multiple compute instances. When a particular packet directed to the overlay IP address is to be routed, one of the multiple next hop paths is selected for routing the packet. This enables packets directed to the IP address to be distributed across the multiple compute instances.

    Abstract: Systems and method for routing data packets in ring network. A data packet being transmitted to a destination node may be received by a first structure at a first node. The first node may determine a number of hops the data packet will traverse as it is transmitted from the first node to the destination node and compare the determined number of hops to a threshold hop value to determine whether the number of hops is equal to or less than the threshold hop value. If the number of hops is greater than the threshold, the data packet may be transmitted to a dimension queuing structure for a first virtual channel within a second node, otherwise, the data packet may be transmitted to a dimension queuing structure for a second virtual channel or a turn queuing structure within the second node.
