Abstract
In general, in one aspect, computer program instructions are to cause, when executed, at least one processor to determine a transmit queue from many transmit queues to associate with a connection, store an identifier of the transmit queue in a connection socket structure associated with the connection, and access the identifier of the transmit queue from a connection socket structure associated with a connection of an egress packet.
Claims13
Computer program instructions, disposed on a non transitory computer readable medium, to cause, when executed, at least one processor element to:
- determine a first transmit queue among a plurality of transmit queues to associate with a connection;
- store an identifier of the first transmit queue in a connection socket structure associated with the connection;
- access the identifier of the first transmit queue from the connection socket structure associated with the connection for a first egress packet, transmission of the first egress packet initiated by a first processor element and to be transmitted via the first transmit queue;
- prevent out-of-order transmission of a second egress packet within the connection due to a change in the association of the connection from the first transmit queue to a second transmit queue among the plurality of transmit queues and based on an uncompleted transmission of the first egress
- packet via the first transmit queue, the second egress packet initiated by a second processor element and to be transmitted via a second transmit queue;
- and
- change the association of the connection from the first transmit queue to the second transmit queue.
