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： Some embodiments provide a method for a network slice selector. From an electronic device, the method receives a connection initiation message for a connection between the electronic device and a network domain. The method exchanges a set of connection initiation messages with the electronic device to set up the connection. The method receives a data message belonging to the connection from the electronic device. The method selects one of multiple network slices to which the electronic device has access as the network slice for the connection based on analysis of the received data message. The method forwards the data message and subsequent data messages belonging to the connection onto the selected network slice to be delivered to the network domain.

摘要： Some embodiments of the invention provide novel methods for performing services on data messages passing through a network connecting one or more datacenters, such as software defined datacenters (SDDCs). The method of some embodiments uses service containers executing on host computers to perform different chains (e.g., ordered sequences) of services on different data message flows. For a data message of a particular data message flow that is received or generated at a host computer, the method in some embodiments uses a service classifier executing on the host computer to identify a service chain that specifies several services to perform on the data message. For each service in the identified service chain, the service classifier identifies a service container for performing the service. The service classifier then forwards the data message to a service forwarding element to forward the data message through the service containers identified for the identified service chain. The service classifier and service forwarding element are implemented in some embodiments as processes that are defined as hooks in the virtual interface endpoints (e.g., virtual Ethernet ports) of the host computer's operating system (e.g., Linux operating system) over which the service containers execute.

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 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： Some embodiments provide a method for a network slice selector that forwards messages from endpoint electronic devices onto different network slices of multiple network slices. The method receives a set of connection initiation messages setting up a connection between an endpoint electronic device and a network domain. The method forwards the set of connection initiation messages from the endpoint electronic device onto a default network slice while storing data regarding the connection initiation messages. After the connection is setup, the method receives a data message belonging to the connection from the endpoint electronic device. The method selects one of the plurality of network slices to which the electronic device has access as the network slice for the connection based on analysis of the received data message. The method retransmits the set of connection initiation messages on the selected network slice between the network slice selector and a network gateway.
