Embodiment 1

[0076] Example 1: Data packet

[0077] The present invention does not affect the efficiency of data transmission due to some poor communication quality channels of the sending host. Because the distribution of the data packets takes into account the integrity of the transport layer data, that is, the IP data packets belonging to the same transport layer data are allocated as a whole. For example, if the length of a UDP data segment is 5000 and the MTU size is 1500, the UDP data segment should be divided into four IP datagrams as follows:

[0078] Identify offset more fragment

[0079] IP Datagram 1 Oxfd2b 0 1

[0080] IP Datagram 2 Oxfd2b 1480 1

[0081] IP Datagram 3 Oxfd2b 2960 1

[0082] IP Datagram 4 Oxfd2b 4440 0

[0083] In the process of implementing allocation, these 4 IP datagrams are divided into one group, and they are allocated as a whole. Imagine that if the allocation is not done in this way, but the allocation granularity is allocated accordin...

Abstract

The invention relates to a data transmission accelerating engine method based on multiple access passages of a transmitting end, which comprises the following steps: after a transmitting end host machine downloads a data packet from an application layer, carrying out TCP multiplexing encapsulation; then delivering the data packet to a TCP / IP protocol stack of a host machine operation system to process; transmitting an encapsulated IP datagram formed by an IP layer to a link layer and then to a physical layer; arriving at a data receiving party by an intermediate routing and demultiplexing by the receiving party. The method is characterized by comprising the following steps: arranging a data transmission accelerating engine between the IP layer and the link layer; grouping the data to be transmitted of the IP datagram according to a mark bit in an IP masthead; then detecting the flow load condition of all transmission passages of the grouped datagram groups by a load balancing module; carrying out predistribution calculation by a corresponding flow distribution algorithm and distributing a data flow to be transmitted to all available transmission passages to transmit in parallel; and finally appointing the predistributed datagram groups to different network interface devices by a data dispatching module.

Description

technical field [0001] The application of the present invention relates to the data scheduling of the data sending end, and in particular to a data transmission acceleration engine based on the multi-access channel method of the sending end. The low utilization rate leads to the problem of low sending data rate, which speeds up the sending rate, improves network bandwidth and communication quality, and belongs to the technical field of network communication. Background technique [0002] Traditional data transmission acceleration solutions generally start with increasing the bandwidth of the existing communication network, typically including: 1) improving the processing capability of the transmission terminal; 2) improving the data forwarding capability of the network intermediate nodes. Obviously, the upgrade and replacement of equipment is required in the realization of these schemes, and the cost is relatively high. [0003] In terms of multi-network interface data tran...
