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: 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: In a slice-based network, slice multiplexers can be used to anchor inter-cloud tunnels across different clouds in a slice path. The slice multiplexers can dynamically change a total allocated bandwidth of an outer tunnel and reconfigure relative slice bandwidths of inner tunnels. This can result in an optimized bandwidth allocation that enforces slice priorities, maintains required SLA performance levels, and minimizes total allocated bandwidth on the network connection. The dynamic changes can be based on slice priority levels, total number of slices, and historical slice throughput.

Abstract: 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.

Abstract: A disclosed example of managing a network include receiving a packet at a first top-of-rack (ToR) switch via a first load-based teaming (LBT) port; determining whether a network location of a destination node of the packet is unknown; based on the network location being unknown, setting an LBT egress control value in the packet, the LBT egress control value to indicate that the packet is not to be transmitted via a second LBT port of a second ToR switch; and sending the packet from the first ToR switch to the second ToR switch via an inter-switch link between the first and second ToR switches and from the first ToR switch to at least a first host that is identified in the packet as the destination node.

Abstract: An example apparatus to manage network resources includes a link aggregator to: aggregate a first plurality of physical network interface cards to create a first link aggregated group, the first link aggregated group corresponding to a first virtual network interface card; and aggregate a second plurality of physical network interface cards to create a second link aggregated group, the second link aggregated group corresponding to a second virtual network interface card; and a link manager to: connect the first link aggregated group between a first distributed virtual port and a first top-of-rack switch; connect the second link aggregated group between a second distributed virtual port and a second top-of-rack switch; and remove an invalid connection between the first plurality of physical network interface cards and the second top-of-rack switch.

An example apparatus includes a packet analyzer to determine that a first virtualized server is preparing to migrate to a second virtualized server based on a data packet, a packet flow path generator to identify a set of network switches between the first virtualized server and the second virtualized server when the first virtualized server is in a different rackmount server than the second virtualized server, and a policy adjustor to adjust a policy of one or more network switches in the set to prioritize a packet flow corresponding to the migration.

Abstract: In a slice-based network, switches can be programmed to perform routing functions based on a slice identifier. The switch can receive a packet and determine a slice identifier for the packet based on packet header information. The switch can use the slice identifier to determine a next hop. Using the slice identifier with a multi-path table, the switch can select an egress interface for sending the packet to the next hop. The multi-path table can ensure that traffic for a slice stays on the same interface link to the next hop, even when a link aggregation group (“LAG”) is used for creation of a virtual channel across multiple interfaces or ports.

Abstract: 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.
