US 11,057,302 B2 · Sending packet

Abstract

Methods of sending a packet, NUMA nodes and non-transitory machine-readable storage mediums are provided in examples of the present disclosure. In one aspect, a first NUMA node queries a forwarding table based on a destination IP address of a packet to be forwarded to obtain a plurality of egress interfaces corresponding to the destination IP address; obtain, for each of the plurality of egress interfaces, node information of a second NUMA node to which the egress interface belongs, determining that the egress interface is on the first NUMA node when the node information of the second NUMA node is same as node information of the first NUMA node, wherein the second NUMA node is on the network device; and send the packet via an egress interface which belongs to the first NUMA node and is in the plurality of egress interfaces.

Dependent claims

A method of sending a packet, comprising:

querying, by a first Non-Uniform Memory Architecture (NUMA) node on a network device, a forwarding table based on a destination IP address of a packet to be forwarded to obtain a plurality of egress interfaces corresponding to the destination IP address;
for each of the plurality of egress interfaces,
obtaining, by the first NUMA node, node information of a second NUMA node to which the egress interface belongs,
determining, by the first NUMA node, that the egress interface is on the first NUMA node when determining that the node information of the second NUMA node is same as node information of the first NUMA node, wherein the second NUMA node is on the network device;
and
sending, by the first NUMA node, the packet via an egress interface which belongs to the first NUMA node and is in the plurality of egress interfaces.

A network device, comprising:

a plurality of Non-Uniform Memory Architecture (NUMA) nodes,
wherein a first NUMA node in the plurality of NUMA nodes comprises:
a processor, and
a non-transitory machine-readable storage medium storing machine executable instructions which are executable by the processor to:
query a forwarding table based on a destination IP address of a packet to be forwarded to obtain a plurality of egress interfaces corresponding to the destination IP address;
for each of the plurality of egress interfaces, obtain node information of a second NUMA node to which the egress interface belongs, determine that the egress interface is on the first NUMA node when determining that the node information of the second NUMA node is same as node information of the first NUMA node, wherein the second NUMA node is on the network device;
and
send the packet via an egress interface which belongs to the first NUMA node and is in the plurality of egress interfaces.

5 more elements

A non-transitory machine-readable storage medium storing machine executable instructions which are invoked and executed by a processor of a network device to:

query a forwarding table based on a destination IP address of a packet to be forwarded to obtain a plurality of egress interfaces corresponding to the destination IP address;
for each of the plurality of egress interfaces,
obtain node information of a second NUMA node to which the egress interface belongs,
determine that the egress interface is on the first NUMA node when determining that the node information of the second NUMA node is same as node information of the first NUMA node, wherein the second NUMA node is on the network device;
and
send the packet via an egress interface which belongs to the first NUMA node and is in the plurality of egress interfaces.
