In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is a kind of method flow diagram E-Packeted that the embodiment of the present invention provides.As shown in Figure 1, the method can comprise:
The packet storage that network interface card receives by S101, kernel state receiving process is in shared drive and notify User space process.
S102, User space process, by after the physical address map of shared drive to the virtual address of User space process, are extracted message and process message from shared drive.
S103, User space process by process after packet storage in shared drive and notify kernel state send process.
S104, kernel state are sent process and are sent by corresponding network interface card by the message after process.
Wherein, shared drive is that kernel state distributes when initialization.Concrete, kernel state, when initialization, can distribute first piece of continuous print physical memory of certain capacity for building shared drive, and can be divided by distribute continuous print physical memory further.Such as, kernel state is when initialization, can allocated size be that the continuous physical memory of 16M is for building shared drive, further, also the continuous physical memory of distributed 16M can be divided into 8K memory block, the size that can calculate each memory block is like this 2K, and is the message that the memory block of 2K is used for storing kernel state receiving process and receives by size.
Kernel state, when initialization, except distributing the continuous print physical memory of certain capacity for building except shared drive, also distributes second piece of continuous print physical memory for building receiving queue and transmit queue.Wherein, the block address memory of message of constructed receiving queue for storing kernel state receiving process and receiving, constructed transmit queue sends the block address memory of the message after process process for storing kernel state.Such as, suppose that kernel state is when initialization, allocated size is that the continuous physical memory of 16M is for building shared drive, and the continuous physical memory of distributed 16M is divided into 8K memory block, the address of further hypothesis 1K memory block needs to preserve with a queue, at this moment, kernel state is when initialization, except allocated size is that the continuous physical memory of 16M is for building except shared drive, also need to distribute another block internal memory for preserving 8 receiving queues and 8 transmit queues, wherein, 8 receiving queues can be: be qos [1], qos [2], qos [3], qos [4], qos [5], qos [6], qos [7], qos [8], 8 transmit queues can be: qos [9], qos [10], qos [11], qos [12], qos [13], qos [14], qos [15], qos [16].
Concrete, when being stored in receiving queue by the block address memory of message, Hash operation is carried out in source IP address and the object IP address of the message that can receive according to kernel state receiving process; According to the value obtained after Hash operation, determine the queue value of kernel state receiving queue; According to the queue value of the kernel receiving queue determined, the block address memory of message is stored in corresponding receiving queue, to ensure the homology chummage of message.
Wherein, Hash operation is exactly after receiving message, first from 32 bits of the source IP address of message, object IP address, extract respectively the binary number of fixed position, fixed qty, such as 12 to 20 totally 9 figure places, then this group number is carried out xor operation, and carry out the operation of remainder number according to number of queues.Like this, just by different packet storages in different receiving queues, the homology chummage of message can be also ensure that simultaneously.
In addition, kernel state is when initialization, except distributing first piece of continuous print physical memory of certain capacity for building shared drive and second piece of continuous print physical memory for building except receiving queue, transmit queue, also can distribute the 3rd piece of continuous print physical memory, for head pointer and the tail pointer of the head pointer and tail pointer and transmit queue that store receiving queue.
Such as, suppose that kernel state is when initialization, allocated size is that the continuous physical memory of 16M is for building shared drive with another block internal memory for preserving 8 receiving queues and 8 transmit queues.Further hypothesis 8 receiving queues are respectively: qos [1], qos [2], qos [3], qos [4], qos [5], qos [6], qos [7], qos [8], 8 transmit queues are respectively: qos [9], qos [10], qos [11], qos [12], qos [13], qos [14], qos [15], qos [16], head pointer and the tail pointer of above-mentioned 8 receiving queues of further hypothesis are respectively: be qos [1] .head, qos [2] .head, qos [3] .head, qos [4] .head, qos [5] .head, qos [6] .head, qos [7] .head, qos [8] .head, qos [1] .tail, qos [2] .tail, qos [3] .tail, qos [4] .tail, qos [5] .tail, qos [6] .tail, qos [7] .tail, qos [8] .tail, head pointer and the tail pointer of above-mentioned 8 transmit queues are respectively: be qos [9] .head, qos [10] .head, qos [11] .head, qos [12] .head, qos [13] .head, qos [14] .head, qos [15] .head, qos [16] .head, qos [9] .tail, qos [10] .tail, qos [11] .tail, qos [12] .tail, qos [13] .tail, qos [14] .tail, qos [15] .tail, qos [16] .tail.
At this moment, kernel state, when initialization, also needs to distribute another block continuous print physical memory, for head pointer and the tail pointer of the head pointer and tail pointer and above-mentioned 8 transmit queues of depositing above-mentioned 8 receiving queues.
Kernel state is when initialization, not only distribute first piece of continuous print physical memory for building shared drive, second piece of continuous print physical memory for building receiving queue and transmit queue and the 3rd piece of continuous print physical memory for the head pointer of the head pointer and tail pointer and transmit queue that store up receiving queue and tail pointer, but also records the first address of the first address of first piece of continuous print physical memory, the first address of second piece of continuous print physical memory and the 3rd piece of continuous print physical memory distributed.Like this, the first address of distribute first piece continuous print physical memory of User space process by record, the first address of the first address of second piece of continuous print physical memory and the 3rd piece of continuous print physical memory, can read the first address of first piece of continuous print physical memory and size, the first address of second piece of continuous print physical memory and the first address of size and the 3rd piece of continuous print physical memory thereof and size thereof.And, first address and the size thereof of first piece of continuous print physical memory is read in User space process, after the first address of the first address of second piece of continuous print physical memory and size and the 3rd piece of continuous print physical memory and size thereof, the virtual address of the address of first piece of continuous print physical memory and User space process is made to set up mapping relations by calling system function, like this, the mapping relations of User space process by setting up, the message stored in memory block is processed, therefore, User space process directly can have access to the message that kernel state receives, thus avoid the copy of message from kernel state to User space, improve the forwarding speed of message, simultaneously, also save system resource.
In above-mentioned steps S101, the packet storage that network interface card receives by kernel state receiving process is in shared drive and notify User space process, be specially: kernel state receiving process applies for memory block from memory pool, the address of the memory block applied in the memory block applied for, and is inserted into the tail of the queue of receiving queue by the packet storage received by network interface card; User space process poll receiving queue, reads the address of memory block from receiving queue head, until receiving queue is empty; When receiving queue is empty, User space process enters sleep state, until wake User space process up during receiving queue non-NULL.Can find out, adopt wake-up waiting mechanism and interrupt the mode that combines of poll, the expense of CPU when deducting idle, thus improve forwarding speed and the resource utilization ratio of message.
In above-mentioned steps S102, User space process is extracted message and is processed message from shared drive, be specially: User space process reads the address of the memory block of stored messages from the receiving queue team head of shared drive, the address according to memory block is read the content of message to the corresponding position of memory pool and processes message.
In above-mentioned steps S103, User space process by process after packet storage in shared drive and notify kernel state send process, be specially: the address of the memory block of the message after process is inserted into transmit queue tail of the queue by User space process, and calling system function notice kernel state sends process.
Below by a concrete example, detailed explanation explanation is carried out to above-mentioned content.
In order to describe for simplicity, suppose that receiving queue only has a queue to be qos [M] and this queue is current for empty.Further hypothesis kernel state receiving process is message 1, message 2, message 3 according to the message that time order and function is received sequentially, then kernel state receiving process is after receiving message 1, message 2, message 3, from shared drive application to memory block 1 for stored messages 1, apply for memory block 2 for stored messages 2 and application to memory block 3 for stored messages.The physical address of the memory block 1 that further hypothesis is applied for is 001, the physical address of memory block 2 is 002 (binary system is 0010), the physical address of memory block 3 is 003 (binary system is 0011).Then, be 001 by the physical address of memory block 1, the physical address of memory block 2 is 002, the physical address of memory block 3 is 003 be stored in receiving queue qos [M] successively, then the physical address 001 of message 1 is stored in the head of receiving queue qos [M], and the physical address 003 of message 3 is stored in the afterbody of receiving queue qos [M].Now, User space process by calling system function, and according to the head pointer of receiving queue qos [M] and tail pointer, makes physical address 001, physical address 002, physical address 003 set up mapping relations with the virtual address of User space process.Like this, User space process, according to set up mapping relations, can process message 1, message 2, message 3, therefore, User space process directly can have access to the message that kernel state receives, thus avoids the copy of message from kernel state to User space, has saved system resource.
On basis based on above-mentioned example, suppose that transmit queue is qos [N] and current for empty.After User space process processes message 1, message 2, message 3, successively the physical address 002 of the physical address 001 of message 1, message 2, the physical address 003 of message 3 are stored to transmit queue qos [N], kernel state sends and carries out by arriving transmit queue qos [N], and according to physical address 001, the physical address 002 of message 2, the physical address 003 of message 3 of message 1 in transmit queue qos [N], read message 1, message 2, message 3, and message 1, message 2, message 3 are sent on corresponding network interface card.After message 1, message 2, message 3 are sent to corresponding network interface card by kernel state transmission process, memory block 1, memory block 2, memory block 3 are discharged, at this moment, kernel state sends physical address 001, the physical address 002 of memory block 2, the physical address 003 of memory block 3 of memory block 1 that process reclaims memory block 1, memory block 2, memory block 3 and distributes.
The mode of first in first out that what above-mentioned receiving queue qos [M], transmit queue qos [N] adopted is, in the specific implementation, receiving queue and transmit queue also can adopt mode first-in last-out, no longer describe in detail mode first-in last-out at this.
Message in the embodiment of the present invention can be 5 tuple messages, also can be the message of other type.
