Abstract: Example methods are provided to perform traffic forwarding between geographically dispersed first site and second site and to support traffic forwarding via a trunk interface. In one example, the method may include receiving, by a first edge device at the first site, network traffic having a plurality of packets via a trunk interface of the first edge device from a virtual tunnel endpoint, the virtual tunnel endpoint having decapsulated the packets prior to communicating the packets through the trunk interface. The method may further include reading an overlay network identifier from each of the packets to identify a source overlay network of the received network traffic from the multiple overlay networks; modifying each of the packets to include a virtual local area network (VLAN) identifier; and forwarding modified network traffic to a second edge device at the second site to identify the destination network based on the VLAN identifier.

Abstract: Described herein are systems, methods, and software to enhance the management of packet filters for host computing systems. In one implementation, a method of managing packet filters for a physical network interface on a host computing system includes obtaining dispatch statistics for media access control (MAC) addresses associated with virtual nodes communicating over the physical network interface via a virtual switch. After obtaining the dispatch statistics, the method further provides identifying a filter configuration based on the dispatch statistics, wherein the filter configuration classifies received packets at the physical network interface into processing queues based on attributes identified in the received packets, and applying the filter configuration in the physical network interface.

Abstract: Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).

Abstract: The disclosure herein describes a computer system that facilitates multi-core processing of VXLAN encapsulated packets. A VXLAN encapsulated packet typically contains an outer Ethernet header, an outer IP header, an outer UDP header, and an inner Ethernet header. The computer system hosts virtualization software which includes a virtual switch, a VXLAN module, and a load balancer. The load balancer monitors a port on the virtual switch. This port is dedicated to receiving VXLAN encapsulated packets and can be referred to as a VXLAN VMKNIC port. When the traffic statistics on the VXLAN VMKNIC port surpasses a predetermined threshold, the load balancer can instruct the physical network interface to allocate a number of receiver side scaling (RSS) queues. In turn, the physical network interface can store received VXLAN encapsulated packets in a number of RSS receive queues which facilitates multi-core processing of the received encapsulated packets.
