Abstract: Example methods and systems for logical overlay tunnel monitoring are described. One example may involve a first computer system obtaining control information identifying a list of multiple logical overlay tunnels to be monitored, including a first logical overlay tunnel between a first virtual tunnel endpoint (VTEP) and a second VTEP. Based on the control information, a first monitoring agent may configure and inject a probe packet at the first VTEP to cause the first VTEP to perform encapsulation and send an encapsulated probe packet over the first logical overlay tunnel. In response, an encapsulated response packet that includes a response packet may be received from the second monitoring agent over the first logical overlay tunnel. Based on the response packet, a tunnel performance metric associated with the first logical overlay tunnel may be determined.

Abstract: Example methods are provided for a host to perform packet handling based on a microprocessor architecture configuration that includes a first node and a second node. One example method may comprise detecting, from a virtualized computing instance supported by the host, an egress packet for transmission to a destination via one of multiple physical network interface controllers (PNICs) of the host. The method may also comprise: identifying the first node assigned to the virtualized computing instance and selecting a first PNIC associated with the first node assigned to the virtualized computing instance. The multiple PNICs may include the first PNIC, and a second PNIC associated with the second node. The method may further comprise sending the egress packet to the destination via the first PNIC associated with the first node.

Abstract: An example method of beacon probing in a computing system includes: sending, by cross-host beacon probing (CHBP) software executing in a first host of the computing system, a first beacon probe from a first network interface controller (NIC) of the first host to NICs on a same layer 2 domain as the first NIC, the NICs including a second NIC of the first host and cross-host NICs of at least one host other than the first host; receiving, at the CHBP software through the first NIC, acknowledgements (ACKs) to the first beacon probe from the cross-host NICs; and determining, in response to the first beacon probe, connectivity statuses of the first NIC and the second NIC by the CHBP software based on the ACKs and on whether the second NIC receives the first beacon probe.

Abstract: An example method of distributed load balancing in a virtualized computing system includes: configuring, at a logical load balancer, a traffic detector to detect traffic to a virtual internet protocol address (VIP) of an application having a plurality of instances; detecting, at the traffic detector, a first request to the VIP from a client executing in a virtual machine (VM) supported by a hypervisor executing on a first host; sending, by a configuration distributor of the logical load balancer in response to the detecting, a load balancer configuration to a configuration receiver of a local load balancer executing in the hypervisor for configuring the local load balancer to perform load balancing for the VIP at the hypervisor using the load balancer configuration.
