Abstract: Example methods and systems for packet handling based on a multiprocessor architecture configuration are provided. One example method may comprise: in response to receiving a first ingress packet that requires processing by a first virtual central processing unit (VCPU) running on the first node, steering the first ingress packet towards a first receive (RX) queue and performing local memory access on the first node to access the first ingress packet from the first RX queue. The method may also comprise: in response to receiving a second ingress packet that requires processing by a second VCPU running on the second node, steering the second ingress packet towards a second RX queue and performing local memory access on the second node to access the second ingress packet from the second RX queue.

Abstract: Example methods and computer systems are provided for filter-based packet handling at a virtual network adapter. The method may comprise: receiving an ingress packet destined for the virtualized computing instance that is supported by the host and connected to the virtual network adapter; and matching the ingress packet to one of multiple filters configured for the virtual network adapter. The multiple filters may include a first filter specifying one or more first packet characteristics and a second filter specifying one or more second packet characteristics. The method may also comprise: in response to matching the ingress packet to the first filter, assigning the ingress packet to a first packet queue; and in response to matching the ingress packet to the second filter, assigning the ingress packet to a second packet queue.

Abstract: Example methods and systems for memory leak detection. One example may comprise: identifying a set of memory buffers that are available for storing packet information that requires processing by the network device; a first subset that includes one or more first memory buffers that are unallocated, and a second subset that includes one or more second memory buffers that are allocated and storing packet information that is being processed by the network device. The method may also comprise: performing a comparison between (a) the set of memory buffers and (b) the first subset and the second subset; and based on the comparison, identifying a third subset that includes one or more third memory buffers, being leaked memory buffers, that are storing packet information that is no longer being processed by the network device.
