Abstract: Techniques for using proxies with overprovisioned IP addresses to demultiplex data flows, which may otherwise look the same at L7, into multiple subflows for L3 policy enforcement without having to modify an underlying L3 network. The techniques may include establishing a subflow through a network between a first proxy and a second proxy, the subflow associated with a specific policy. In some examples, the first proxy node may receive an encrypted packet that is to be sent through the network and determine, based at least in part on accessing an encrypted application layer of the packet, a specific application to which the packet is to be sent. The first proxy node may then alter an IP address included in the packet to cause the packet to be sent through the network via the subflow such that the packet is handled according to the specific policy.

The example systems can be configured to periodically classify pick jobs in order to optimize throughput of the fulfillment center. The classifying can include determining an estimated completion time for pick jobs and identifying at-risk jobs that may complete after their associated due dates. The at-risk jobs can be assigned to autonomous vehicles based primarily on their associated due dates. Other pick jobs that are not at-risk can be assigned to autonomous vehicles based primarily on efficiency. The at-risk pick jobs can be assigned to autonomous vehicles before the other pick jobs.
