Abstract
Embodiments of the present invention provide a system, method, and computer program product that enables applications transferring data packets over a network to a multi-processing system to choose how the data packets are going to be processed by, e.g., allowing the applications to pre-assign connections to a particular network thread and migrate a connection from one network thread to another network thread without putting the connection into an inconsistent state.
Claims12
A method comprising:
- halting processing of data packets arriving on an established network connection until the connection is migrated to a new network context that queues connections processed by a network thread without putting the connection in an inconsistent state;
- migrating the connection to the new network thread;
- removing a link to a portable control block (PCB) storing information about the connection in migration from a first data structure corresponding to the network thread from which the connection will be migrated to a temporary queue;
- and
- placing the PCB to a new data structure corresponding to a new network thread to which the connection is migrated.
A computer-readable device having stored thereon instructions for performing a method for enabling applications to flexibly distribute data packets in a multiprocessing system, the method comprising machine executable code which when executed by at least one machine, causes the machine to:
- halt processing of data packets arriving on an established network connection until the connection is migrated to a new network context that queues connections processed by a network thread without putting the connection in an inconsistent state;
- migrate the connection to the new network thread;
- remove a link to a portable control block (PCB) storing information about the connection in migration from a first data structure corresponding to the network thread from which the connection will be migrated to a temporary queue;
- and
- place the PCB to a new data structure corresponding to a new network thread to which the connection is migrated.
