Abstract: In an example, a network switch is configured to natively act as a high-speed load balancer. Numerous load-balancing techniques may be used, including one that bases the traffic “bucket” on a source IP address of an incoming packet. This particular technique provides a network administrator a powerful tool for shaping network traffic. For example, by assigning certain classes of computers on the network particular IP addresses, the network administrator can ensure that the traffic is load balanced in a desirable fashion. To further increase flexibility, the network administrator may apply a bit mask to the IP address, and expose only a portion, selected from a desired octet of the address.

Abstract: In one embodiment, a network element that performs network traffic bridging receives load balancing criteria comprising an indication of at least one transport layer port number and an indication of a plurality of network nodes. A plurality of forwarding entries are created based on the load balancing criteria. A forwarding entry specifies the at least one transport layer port number and a network node of the plurality of network nodes. The network element applies the plurality of forwarding entries to network traffic to load balance, among the plurality of network nodes, network traffic that matches the at least one transport layer port number.

Abstract: The present disclosure relates to providing shared resources to virtual devices on a network switch. In one example, a switch comprises a plurality of virtual device contexts (VDCs) and a default virtual device context (DVDC). The DVDC stores configuration data that identifies a network resource. The DVDC transmits a reference to the configuration data to each of the plurality of VDCs. Each of plurality of VDCs receives the reference from the DVDC. When the DVDC receive, from the at least one of the plurality of VDCs, a request to access the configuration data via the reference, the DVDC transmits at least a portion of the configuration data to the at least one of the plurality of VDCs. The at least the portion of the configuration data is operable to initiate a connection between the at least one of the plurality of VDCs and the network resource.

Abstract: In one embodiment, a maximum transmission unit (MTU) mismatch assessment service receives a notification of a mismatch between a packet size of a packet sent by a source to a destination in a network and an MTU of an intermediate router between the source and destination in the network. The service determines, using a machine learning-based model, that the mismatch represents a persistent MTU mismatch condition at the intermediate router. The service identifies a target router in the network to receive a configuration adjustment instruction, based on the persistent MTU mismatch condition. The service sends the configuration adjustment instruction to the target router, to alleviate the persistent MTU mismatch condition at the intermediate router.

Abstract: An approach enables networking functionality to be configured at network switches for containers hosted by computing devices. A container supervisor on the network switch is configured to obtain, via a container network manager, container attribute data for containers hosted by the computing devices. The container network manager is configured to interact with and manage container orchestration engines on behalf of the containers. This allows the network switch to be container orchestration agnostic. The network switch enables networking functionality for the containers by updating container configuration data on the networking switch based upon the container attribute data obtained from the container network manager. This may include, for example, updating hardware tables on the network switch with the container attribute data to allow the network switch, and applications executing on the network switch, to perform networking functionality with respect to the containers.

Abstract: Embodiments include receiving configuration information including a match criterion for packets received at a network device in a network and a pool of layer 3 addresses associated with a set of servers in the network, resolving layer 2 destination addresses based on the layer 3 addresses of the servers, and programming a hardware layer of the network device based, at least in part, on the match criterion, the pool of layer 3 addresses, and the layer 2 destination addresses. Specific embodiments include configuring a policy to indicate that packets from an external source are to be forwarded to a server of the set of servers. Further embodiments include receiving a packet at the network device, and matching the packet to the pool of layer 3 addresses and the resolved layer 2 addresses based, at least in part, on the match criterion programmed in the hardware layer.
