Embodiment
Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
In prior art, after network interface receives packet, need first notification architecture system kernel, determine which CPU this packet should be assigned to by it; After CPU is disposed packet, also need first notification architecture system kernel, determine packet by which network interface is sent by it.Cause packet longer in the network interface time of staying like this, when the comparatively large and reception limited space of network interface of data packet number, can data-bag lost be caused.As shown in Figure 2, be the system schematic of the transceiving data bag that the embodiment of the present invention provides, this system comprises: network interface 201 and processor 202; Between network interface 201 and processor 202, set up corresponding mapping relations in advance, and by these mapping relations, between network interface and processor 202, carry out information interaction.
Wherein, network interface 201 is according to network interface transmission route limit value, and the preset mapping relation between network interface 201 and processor 202, the receives data packets request in network interface transmit queue is sent to processor 202, from internal memory, obtains this packet for processor 202; The receives data packets response returned after network interface 201 receiving processor 202 pairs of packets are disposed, by this receives data packets response buffer to network interface receiving queue, after reading the response of this receives data packets, discharge the resource that this packet takies at network interface 201;
Processor 202 is according to processor transmission route limit value, and the preset mapping relation between network interface 201 and processor 202, Packet Generation request in processor transmit queue is sent to network interface 201, from internal memory, obtains this packet for network interface 201; Processor 202 receives the Packet Generation response returned after network interface 201 sends packet, by this Packet Generation response buffer to processor receiving queue, after reading the response of this Packet Generation, discharges the resource that this packet takies at processor 202.
Preferably, network interface transmit queue and network interface receiving queue are the space for buffered message set up in advance in the memory headroom of network interface 201 correspondence; Processor transmit queue and processor receiving queue are the space for buffered message set up in advance in the memory headroom of processor 202 correspondence.
And network interface 201 adopts the mode of poll or down trigger to read Packet Generation request in network interface receiving queue and/or receives data packets response; Processor 202 adopts the receives data packets request in the mode reading processor receiving queue of poll or down trigger and/or Packet Generation to respond.
Wherein, this preset mapping relation is the corresponding processor of a network interface or the corresponding processor of multiple network interface.Network interface transmission route limit value is used for marked network interface and sends the ability of information, its initial value be greater than one integer value, processor transmission route limit value is used for the ability that identification processor sends information, its initial value be greater than one integer value.This network interface transmission route limit value can set according to the performance parameter etc. of network interface; Processor transmission route limit value can set according to performance parameters etc. such as the disposal abilities of processor.
