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: 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: A switch in a slice-based network can be used to enforce quality of service (“QoS”). Agents can run in the switches, such as in the core of each switch. The switches can sort ingress packets into slice-specific ingress queues in a slice-based pool. The slices can have different QoS prioritizations. A switch-wide policing algorithm can move the slice-specific packets to egress interfaces. Then, one or more user-defined egress policing algorithms can prioritize which packets are sent out into the network first based on slice classifications.

Abstract: Methods, apparatus, and articles of manufacture are disclosed to improve resource allocation for virtualized server systems. An example apparatus includes a resource identifier to identify a set of external storage resources when a host storage solution is not identified, a storage cost calculator to calculate a cost corresponding to the external storage resource set by comparing a parameter of an external storage resource in the external storage resource set to a requirement, a cost analyzer to determine whether the cost satisfies a cost threshold by comparing the cost to a cost threshold, and a workload domain allocator to allocate the external storage resource set to the workload domain when the cost satisfies the cost threshold.

Abstract: Methods, apparatus, systems, and articles of manufacture to improve packet flow among virtualized servers are disclosed. An example apparatus includes memory, and hardware to execute instructions to generate a load balance list identifying first ones of virtualized network resources having respective values of a utilization status parameter that satisfy a first threshold, in response to at least a number of the first virtualized network resources not satisfying a load balance list threshold, update the load balance list to additionally identify second ones of the virtualized network resources, the second ones of the virtualized network resources having respective values of the utilization status parameter that satisfy a second threshold, the first threshold different from the second threshold, and adjust a policy of a physical hardware resource corresponding to one or more of the virtualized network resources based on the load balance list.

Abstract: A disclosed example includes determining that first virtual machines (VMs) corresponding to a first percentage resource utilization indicative of resource usage of a first rack cause the first rack to generate a threshold amount of heat; determining, based on a second percentage resource utilization indicative of resource usage of a second rack, to migrate the first VMs to the second rack to reduce a temperature in a first room by at least the threshold amount of heat; migrating the first VMs from the first rack of the first room to the second rack of a second room; placing the first rack in a low-power state based on the migration of the first VMs to the second rack; and sending a temperature control signal to a climate control system to adjust a cooling process of the climate control system based on the first rack being in the low-power state.

Abstract: Some embodiments provide a method for a first network slice selector that assigns data messages received from endpoint devices located within a first geographic range to multiple network slices. The method receives a data message from a mobile endpoint device located within the first geographic range. The data message belongs to a connection between the mobile endpoint device and a network domain that began when the mobile device was located in a second geographic range. The method retrieves state that maps the connection to a particular network slice of the network slices from a second network slice selector that assigns data messages received from endpoint devices within the second geographic range to the network slices. The method assigns the data message to the particular network slice.

Abstract: Some embodiments provide a method for a first network slice selector that assigns data messages to a first set of network slices that each comprises an ordered set of network services. The method receives a data message originating from an electronic endpoint device. A second network slice selector previously (i) assigned the data message to a first network slice of a second set of network slices and, (ii) based on the assignment of the data message to the first network slice, provided the data message to the first network slice selector. The method assigns the data message to a second network slice from the first et of network slices. The method provides the data message to a first network service of the selected second network slice.

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.
