摘要： Some embodiments provide a method for establishing multiple virtual service networks over multiple datacenters. The method configures, for each virtual service network of the plurality of virtual service networks, a set of machines distributed across the datacenters to implement an ordered set of network services for the virtual service network. The method configures multiple service network selectors executing within the datacenters to receive a data message, select one of the virtual service networks for the data message based on analysis of contents of the data message, determine a location within the datacenters for a machine implementing a first network service of the ordered set of network services for the selected virtual service network, and transmit the data message to the machine implementing the first network service.

摘要： Some embodiments of the invention provide a novel method of performing network slice-based operations on a data message at a hardware forwarding element (HFE) in a network. For a received data message flow, the method has the HFE identify a network slice associated with the received data message flow. This network slice in some embodiments is associated with a set of operations to be performed on the data message by several network elements, including one or more machines executing on one or more computers in the network. Once the network slice is identified, the method has the HFE process the data message flow based on a rule that applies to data messages associated with the identified slice.

摘要： Examples can include an optimizer that dynamically determines where to place virtual network functions for a slice in a distributed Telco cloud network. The optimizer can determine a slice path that complies with a service level agreement and balances network load. The virtual network functions of the slice can be provisioned at clouds identified by the optimal slice path. In one example, performance metrics are normalized, and tenant-selected weights can be applied. This can allow the optimizer to prioritize particular SLA attributes in choosing an optimal slice path.

摘要： A system can reduce congestion in slice-based networks, such as a virtual service network (“VSN”). The system can include a monitoring module that communicates with agents on switches, such as routers or servers. The switches report telematics data to the monitoring module, which determines slice-specific performance attributes such as slice latency and slice throughput. These slice-specific performance attributes are compared against software license agreement (“SLA”) requirements. When the SLA is not met, the monitoring module can implement a new slice path for the slice to reduce the congestion.

摘要： Some embodiments provide a method for a first network slice selector that selects network slices for connections from endpoint devices located within a first geographic range. The method selects a network slice for a connection between a mobile endpoint device and a network domain that originates when the mobile endpoint device is located within the first geographic range. The method stores state that maps the connection to the selected network slice. The method forwards data traffic belonging to the connection from the mobile endpoint device onto the selected network slice using the stored state. After the mobile endpoint device moves from the first geographic range to a second geographic range, the method receives data traffic belonging to the connection from a second network slice selector that selects network slices for connections from endpoint devices within the second geographic range and forwards said received data traffic onto the selected network slice.
