Abstract: Some embodiments provide a method for configuring a gateway machine in a datacenter. The method receives a definition of a logical network for implementation in the datacenter. The logical network includes at least one logical switch to which logical network endpoints attach and a logical router for handling data traffic between the logical network endpoints in the datacenter and an external network. The method receives configuration data attaching a third-party service to at least one interface of the logical router via an additional logical switch designated for service attachments. The third-party service is for performing non-forwarding processing on the data traffic between the logical network endpoints and the external network. The method configures the gateway machine in the datacenter to implement the logical router and redirect at least a subset of the data traffic between the logical network endpoints and the external network to the attached third-party service.

Abstract: The present disclosure discloses a method and a system for generating a composite PET-CT image based on a non-attenuation-corrected PET image. The method includes: constructing a first generative adversarial network and a second generative adversarial network; obtaining a mapping relationship between a non-attenuation-corrected PET image and an attenuation-corrected PET image by training the first generative adversarial network; obtaining a mapping relationship between the attenuation-corrected PET image and a CT image by training the second generative adversarial network; and generating the composite PET-CT image by utilizing the obtained mapping relationships. According to the present disclosure, a high-quality PET-CT image can be directly composited from a non-attenuation-corrected PET image, and medical costs can be reduced for patients, and radiation doses applied to the patients in examination processes can be minimized.

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.

Abstract: Some embodiments provide a method for forwarding a data message. The method performs a lookup to map a set of header fields of the data message to an identifier corresponding to a service that performs non-forwarding processing on data messages. The method uses a dynamically-updated data structure for the identifier to retrieve instructions for forwarding data messages to the service. The method forwards the data message according to the retrieved instructions from the data structure for the identifier.

Abstract: Some embodiments provide a method for assigning different service path identifiers to each of a set of different service paths along each of which a same set of service operations are performed on a set of packets. The method retrieves an available service path identifier from an identifier storage that stores service path identifiers for multiple service paths. The method generates a set of proposed service path identifiers based on the retrieved available service path identifier and the number of service paths in the set of service paths. The method performs a write operation on the identifier storage based on the set of proposed service path identifiers, and based on a determination that the write operation was successful, assigns the set of proposed service path identifiers to the set of service paths. Based on the set of service path identifiers, the method forwards the set of packets along the set of service paths.
