Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing a joint simulation for satisfying multiple different coexisting commitments to allocate digital resources. In one aspect, a method includes accessing logged data for prior allocations of digital resources, where the logged data includes at least one property associated with respective allocations of the digital resources. Different allocations of the digital resources included in the logged data are assigned to different ones of the multiple different commitments. For each commitment to allocate digital resources, an expected required resource amount that results in the commitment being allocated at least a specified minimum resource based on the allocations of digital resources of the logged data that were assigned to the multiple different commitments is determined.

Abstract: A method for establishing end-to-end tunnels extending across multiple domains using a network element. The method includes receiving a request from a customer controller to implement a virtual network (VN) created by the customer controller, wherein the VN identifies the end-to-end tunnels extending across the multiple domains, mapping the VN to available resources based on network constraints in response to the request, and transmitting, after the VN has been mapped, a message to a network controller managing one of the domains that includes a network path used to form a portion of one of the end-to-end tunnels, wherein the message includes an association object having a Type-Length-Value (TLV) field containing a virtual network identifier binding the network path to the VN.

Abstract: Embodiments disclose a system that allows for improved generation of web requests for scraping that, because of the nature of the requests and time and manner they are sent out, appear more organic, as in human generated, than conventional automated scraping systems. The system then manages how a client request to scrape a target website is made to the site, masking the request in a manner that makes it appear to the Web server as if the request is not generated by an automated system. In this way, by appearing more organic, Web servers may be less likely to block requests from the disclosed system or may take longer to block requests from the disclosed system. By avoiding Web servers blocking requests and extending the lifetime of IP proxies before they are blocked, embodiments can use a limited IP proxy address space more efficiently.

When the first address resolution mapping is verified, the method adds the first address resolution mapping to a list of address resolution mappings. The list of address resolution mappings includes verified address resolution mappings. The list of address resolution mappings is sent to the workload to allow the workload to verify a second address resolution mapping using the list of verified address resolution mappings.

Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node.
