    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 are provided for a network device to perform packet capture in a software-defined networking (SDN) environment. One example method may comprise detecting an egress packet that includes an inner header addressed from a first node to a second node; and identifying a security policy applicable to the egress packet by comparing one or more fields in the inner header with one or more match fields specified by the security policy. The method may further comprise: based on the security policy, capturing the egress packet in an unencrypted form; performing encryption on the egress packet to generate an encrypted packet that includes the egress packet in an encrypted form; and sending the encrypted packet to the second node.

    Abstract: Some embodiments provide a method for updating a core allocation among processes of a gateway datapath executing on a gateway computing device having multiple cores. The gateway datapath processes include a first set of data message processing processes to which a first set of the cores are allocated and a second set of processes to which a second set of the cores are allocated in a first core allocation. Based on data regarding usage of the cores, the method determines a second core allocation that allocates a third set of the cores to the first set of processes and a fourth set of the cores to the second set of processes. The method updates a load balancing operation to load balance received data messages over the third set of cores rather than the first set of cores. The method reallocates the cores from the first allocation to the second allocation.

    Abstract: A method of optimizing network processing in a system comprising a physical host and a set of physical network interface controllers (PNICs) is provided. The physical host includes a forwarding element. The method includes determining that a set of conditions is satisfied to bypass the forwarding element for exchanging packets between a particular data compute node (DCN) and a particular PNIC. The set of conditions includes the particular DCN being the only DCN connected to the forwarding element and the particular PNIC being the only PNIC connected to the forwarding element. The method exchanges packets between the particular DCN and the particular PNIC bypassing the forwarding element. The method determines that at least one condition in said set of conditions is not satisfied. The method utilizes the forwarding element to exchange packets between the particular DCN and the particular PNIC.

    Abstract: The disclosure provides an approach for logical switch level load balancing of Layer 2 virtual private network (L2VPN) traffic. A method of securing communications with a peer gateway generally includes establishing, at a virtual tunnel interface of a local gateway, a plurality of security tunnels with the peer gateway. Each of the plurality of security tunnels is associated with a different set of one or more layer 2 segments and with one or more security associations (SAs) with the peer gateway. The method generally includes receiving a packet, at the local gateway, via a first L2 segment. The method generally includes selecting one of the plurality of security tunnels and an SA associated with the selected security tunnel based on the L2 segment via which the packet was received. The method generally includes encrypting and encapsulating the packet based on the selected security tunnel and SA.
