Abstract: 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.

Abstract: Example methods and systems for pre-validation of network configuration are disclosed. One example may comprise: detecting a request for network configuration to be implemented in a physical network environment; and identifying a set of physical network elements associated with the network configuration. The method may further comprise emulating the set of physical network elements to determine a physical network behaviour caused by the network configuration; and assessing validity of the network configuration based on the physical network behaviour. The set of physical network elements may be emulated using (a) multiple first physical network element emulators and (b) a second physical network element emulator that aggregates the multiple first physical network element emulators.

Abstract: Methods and apparatus to cross configure network resources of software defined data centers are disclosed. Example instructions cause one or more processors to monitor a component of a network for a probe packet sent to the component. The example instructions cause the one or more processors to, in response to detecting the probe packet, determine whether the probe packet includes a unique source media access control (MAC) address that is included in a probe access control list (ACL), the unique source MAC address included in the probe ACL set by a decision engine. The example instructions cause the one or more processors to, in response to determining that the probe packet does not include the unique source MAC address, record probe packet receipt information indicating that the probe packet did not pass through a network port of the component and transmit the probe packet receipt information to the decision engine.

Abstract: 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.

Abstract: 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.

Abstract: Methods and apparatus to cross configure network resources of software defined data centers are disclosed. An example method includes detecting a first configuration change for a first component of a first one of a virtual network or a physical network, the virtual network to provide networking for a virtual computing system, and the physical network to implement the virtual network, identifying, by executing an instruction with a processor, a second component of a second different one of the virtual network or the physical network corresponding to the first component, and making a second configuration change to the second component corresponding to the first configuration change.

Abstract: 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.
