Those skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated in the present disclosure may be employed without departing from the principles of the present disclosure.
As shown in fig. 1, a data packet transmission method in an embodiment of the disclosure includes:
determining a common transmission path in a plurality of transmission paths according to a plurality of transmission paths respectively corresponding to a plurality of data packets to be transmitted;
and transmitting the plurality of data packets to be transmitted together on a common transmission path.
In an alternative embodiment, according to each transmission path of each data packet to be transmitted, a common transmission path in each transmission path is determined, as shown in fig. 2, including:
acquiring a source node and a destination node of a plurality of data packets to be transmitted;
respectively determining a plurality of transmission paths of a plurality of data packets to be transmitted according to a source node and a destination node of the plurality of data packets to be transmitted;
the transmission paths in the same direction among the plurality of transmission paths are determined as a common transmission path.
In the multiple transmission paths, each node may receive respective data packets from different transmission directions, analyze the transmission directions of the respective data packets in the transmission nodes, and determine the transmission paths in the same transmission direction as a common transmission path.
For example, as shown in fig. 3, there are two data packets to be transmitted (data packet A1 and data packet b 1), wherein the data packet A1 is transmitted from the source node A1 to the destination node A2, and the transmission path of the data packet A1 is: node A1-node B1-node C2-node A2, packet B1 being transmitted from source node B1 to destination node B2, the transmission path of packet B1 being: the node B1-node C1-node B2 can determine that the common transmission path of the two data packets is: node B1-node C1.
In an alternative embodiment, the method for transmitting the plurality of data packets to be transmitted together on the common transmission path includes:
the transmission medium moves along the common transmission path;
when the transmission medium reaches the starting point of the common transmission path, packaging a plurality of data packets to be transmitted, and transmitting the data packets by the transmission medium;
when the transmission medium reaches the end of the common transmission path, the plurality of data packets to be transmitted are unpacked.
For example, as shown in fig. 3, during transmission of two data packets, there is a common transmission path (node B1-node C1). In the prior art, two data packets are generally transmitted in serial, so that the common transmission path cannot simultaneously transmit two data packets, the data packet a1 needs to be transmitted first, and the data packet b1 is transmitted after the data packet a1 is transmitted in the common path, so that the transmission time of a plurality of data packets is long when the data packets are transmitted. In addition, for example, the capacity of the transmission medium is 8 bits, and the data bit width of the data packet a1 and the data packet b1 is 4 bits, and if the data packet a1 is transmitted first and then the data packet b1 is transmitted through the common transmission path, this makes the path bit width not fully utilized, resulting in resource waste.
According to the method disclosed by the disclosure, the plurality of data packets to be transmitted on the common transmission path are transmitted together, so that the efficiency of data transmission and the utilization rate of the path bit width can be improved. For example, as shown in fig. 3, the common transmission path of two data packets is node B1-node C1, and node B1 and node C1 are the start point and the end point of the common transmission path, respectively. The transmission medium moves along each transmission path, at the node B1, two data packets (the data packet a1 and the data packet B1) are packed together, the packed data packets a1B1 are transmitted together, the data packets a1B1 are unpacked at the transmission node C1, and the transmission of the data packets a1 and B1 in the common transmission path is completed respectively.
When the transmission medium reaches other nodes except the start point and the end point of the common transmission path in the common transmission path, the plurality of data packets to be transmitted are unpacked and packed for common transmission until the transmission medium reaches the end point of the common transmission path.
According to different designs, the transmission paths of the data packets are different, and the common transmission path determined based on each transmission path may further include other nodes except the start point and the end point of the common transmission path, when the transmission medium reaches the nodes, the data packets packaged together need to be unpacked and packaged again for common transmission. For example, as shown in fig. 4, there are two data packets to be transmitted (data packet A1 and data packet b 1), wherein the data packet A1 is transmitted from the source node A1 to the destination node A2, and the transmission path of the data packet A1 is: node A1-node B1-node C2-node C3-node A2, the data packet B1 being transmitted from the source node B1 to the destination node B2, the transmission path of the data packet B1 being: node B1-node C2-node B2, the common transmission path of two data packets may be determined to be: node B1-node C2, node B1 and node C2 are the start point and end point of the common transmission path respectively, node C1 is the other nodes except the start point and end point in the common transmission path. As described above, the transmission medium moves along each transmission path, at the node B1, two data packets (the data packet a1 and the data packet B1) are packed together, the packed data packets a1B1 are transmitted simultaneously, the data packets a1B1 are unpacked and packed together at the node C1, the packed data packets a1B1 are transmitted together, the data packets a1B1 are unpacked at the node C2, and the transmission of the data packets a1 and B1 in the common transmission path is completed respectively.
In an alternative embodiment, the method further comprises:
the transmission medium moves along a plurality of the transmission paths;
when the transmission medium reaches a source node of a data packet to be transmitted, any data packet to be transmitted is packed and transmitted by the transmission medium;
when the transmission medium reaches any destination node of the data packet to be transmitted, the data packet to be transmitted is unpacked.
In the transmission process of the data packet to be transmitted, the transmission path may include other nodes besides the common transmission path. For other nodes than the common transmission path, when the transmission medium reaches each node, the respective data packets to be transmitted may be parsed to determine what operation is performed on the data packets to be transmitted. When the transmission medium reaches the source node of the data packet to be transmitted, the data packet to be transmitted is packed, when the transmission medium reaches the destination node of the data packet to be transmitted, unpacking is carried out on the data packet to be transmitted to finish transmission, and when the transmission medium reaches other transmission nodes except the source node and the destination node of the data packet to be transmitted, unpacking and repacking are carried out on the data packet to be transmitted.
In an alternative embodiment, when the transmission medium reaches a source node of any data packet to be transmitted, the data packet to be transmitted is packed and transmitted by the transmission medium, including:
judging whether the current node is a destination node of another data packet to be transmitted, if so, unpacking the other data packet to be transmitted, and then packing the data packet to be transmitted; if not, directly packaging the data packet to be transmitted.
For example, as shown in fig. 3, the transmission medium moves along each transmission path, and when the transmission medium reaches the node A1, i.e., the source node of the data packet A1, the data packet A1 is packetized; when the transmission medium arrives at the node B1, i.e. the source node of the data packet B1, the data packet a1 is unpacked, and the data packet a1 and the data packet B1 are packed together and transmitted simultaneously; when the transmission medium reaches the node C1, unpacking the data packet a1b1, and packing the data packet a1 and the data packet b1 respectively; when the transmission medium reaches the node C2, unpacking and packing the data packet a 1; when the transmission medium reaches the node A2, namely the destination node of the data packet a1, the data packet a1 is unpacked, the transmission of the data packet a1 is completed, and when the transmission medium reaches the node B2, namely the destination node of the data packet B1, the data packet B1 is unpacked, and the transmission of the data packet B1 is completed.
In an alternative embodiment, the data packet to be transmitted includes the address of the destination node;
when the transmission medium reaches any destination node of the data packet to be transmitted, unpacking the data packet to be transmitted, including:
analyzing the data packet to be transmitted, and determining the address of the destination node of the data packet to be transmitted;
when the transmission medium reaches the own destination node, the data packet to be transmitted is unpacked.
For example, as shown in fig. 3, when the transmission medium arrives at the node C1 during the movement process from the start point to the end point of the transmission path, the data packet a1B1 is unpacked, and the data packet a1 contains the address of the destination node A2, so that the data packet B1 can be resolved to continue to be transmitted to the node C2, and the data packet B1 can continue to be transmitted to the node B2, because the data packet a1 contains the address of the destination node A2; when the transmission medium reaches the node C2, unpacking the data packet a1, and because the data packet a1 contains the address of the destination node A2, the data packet a1 can be analyzed to continue to be transmitted to the transmission node A2, and the data packet a1 is unpacked; when the transmission medium reaches the node A2, unpacking the data packet a1, and analyzing that the data packet a1 reaches the destination node because the data packet a1 contains the address of the destination node A2, so as to finish the transmission of the data packet a 1; when the transmission medium arrives at the node B2, the data packet B1 is unpacked, and the data packet B1 arrives at the destination node after the data packet B1 contains the destination node B2 address, so that the transmission of the data packet B1 is completed.
In an alternative embodiment, the data packets to be transmitted include data volume information;
when the transmission medium reaches any source node of the data packet to be transmitted, the data packet to be transmitted is packed and transmitted by the transmission medium, and the method comprises the following steps:
judging whether the data quantity of the data packet to be transmitted is larger than the capacity allowance of a transmission medium or not;
if the data quantity of the data packet to be transmitted is larger than the capacity allowance of the transmission medium, delay packaging the data packet to be transmitted;
and if the data quantity of the data packet to be transmitted is smaller than or equal to the capacity allowance of the transmission medium, packaging the data packet to be transmitted.
The bandwidth of the transmission medium refers to the amount of data that can be transmitted at a fixed time (e.g., every clock), and the capacity of the transmission medium is equal to or less than the bandwidth. Because the capacity of the transmission medium is fixed, for example, the data volume capable of being transmitted is fixed in one clock period, in the transmission process of a plurality of data packets, the data volume of each data packet to be transmitted needs to be judged at each transmission node, and the smooth transmission process of each data packet to be transmitted is ensured. For example, assuming that the data bit width of the data packet a1 is 4 bits, the data bit width of the data packet b1 is 4 bits, the data packet c1 is already packed at one node, and assuming that the data packet c1 is still required to be packed at the transmission node, the remaining capacity of the transmission medium is 2 bits, it is determined that the capacity of the transmission medium is insufficient, the data packet c1 cannot be packed, one clock cycle is delayed, and the data packet c1 is packed at the next clock cycle.
As shown in fig. 5, a data packet transmission system according to an embodiment of the present disclosure includes:
the common path determining module is used for determining a common transmission path in a plurality of transmission paths according to a plurality of transmission paths respectively corresponding to a plurality of data packets to be transmitted;
and the data transmission module is used for commonly transmitting the plurality of data packets to be transmitted on a common transmission path.
In an alternative embodiment, the common path determination module is further configured to:
acquiring a source node and a destination node of a plurality of data packets to be transmitted;
respectively determining a plurality of transmission paths of a plurality of data packets to be transmitted according to a source node and a destination node of the plurality of data packets to be transmitted;
the transmission paths in the same direction among the plurality of transmission paths are determined as a common transmission path.
In the multiple transmission paths, each node may receive respective data packets from different transmission directions, analyze the transmission directions of the respective data packets in the transmission nodes, and determine the transmission paths in the same transmission direction as a common transmission path.
For example, as shown in fig. 3, there are two data packets to be transmitted (data packet A1 and data packet b 1), wherein the data packet A1 is transmitted from the source node A1 to the destination node A2, and the transmission path of the data packet A1 is: node A1-node B1-node C2-node A2, packet B1 being transmitted from source node B1 to destination node B2, the transmission path of packet B1 being: the node B1-node C1-node B2 can determine that the common transmission path of the two data packets is: node B1-node C1.
In an alternative embodiment, the data transmission module is further configured to:
the transmission medium moves along the common transmission path;
when the transmission medium reaches the starting point of the common transmission path, packaging a plurality of data packets to be transmitted, and transmitting the data packets by the transmission medium;
when the transmission medium reaches the end of the common transmission path, the plurality of data packets to be transmitted are unpacked.
For example, as shown in fig. 3, during transmission of two data packets, there is a common transmission path (node B1-node C1). In the prior art, two data packets are generally transmitted in serial, so that the common transmission path cannot simultaneously transmit two data packets, the data packet a1 needs to be transmitted first, and the data packet b1 is transmitted after the data packet a1 is transmitted in the common path, so that the transmission time of a plurality of data packets is long when the data packets are transmitted. In addition, for example, the capacity of the transmission medium is 8 bits, and the data bit width of the data packet a1 and the data packet b1 is 4 bits, and if the data packet a1 is transmitted first and then the data packet b1 is transmitted through the common transmission path, this makes the path bit width not fully utilized, resulting in resource waste.
According to the system disclosed by the disclosure, the plurality of data packets to be transmitted on the common transmission path are transmitted together, so that the efficiency of data transmission and the utilization rate of the path bit width can be improved. For example, as shown in fig. 3, the common transmission path of two data packets is node B1-node C1, and node B1 and node C1 are the start point and the end point of the common transmission path, respectively. The transmission medium moves along each transmission path, at the node B1, two data packets (the data packet a1 and the data packet B1) are packed together, the packed data packets a1B1 are transmitted together, the data packets a1B1 are unpacked at the transmission node C1, and the transmission of the data packets a1 and B1 in the common transmission path is completed respectively.
When the transmission medium reaches other nodes except the start point and the end point of the common transmission path in the common transmission path, the plurality of data packets to be transmitted are unpacked and packed for common transmission until the transmission medium reaches the end point of the common transmission path.
According to different designs, the transmission paths of the data packets are different, and the common transmission path determined based on each transmission path may further include other nodes except the start point and the end point of the common transmission path, when the transmission medium reaches the nodes, the data packets packaged together need to be unpacked and packaged again for common transmission. For example, as shown in fig. 4, there are two data packets to be transmitted (data packet A1 and data packet b 1), wherein the data packet A1 is transmitted from the source node A1 to the destination node A2, and the transmission path of the data packet A1 is: node A1-node B1-node C2-node C3-node A2, the data packet B1 being transmitted from the source node B1 to the destination node B2, the transmission path of the data packet B1 being: node B1-node C2-node B2, the common transmission path of two data packets may be determined to be: node B1-node C2, node B1 and node C2 are the start point and end point of the common transmission path respectively, node C1 is the other nodes except the start point and end point in the common transmission path. As described above, the transmission medium moves along each transmission path, at the node B1, two data packets (the data packet a1 and the data packet B1) are packed together, the packed data packets a1B1 are transmitted simultaneously, the data packets a1B1 are unpacked and packed together at the node C1, the packed data packets a1B1 are transmitted together, the data packets a1B1 are unpacked at the node C2, and the transmission of the data packets a1 and B1 in the common transmission path is completed respectively.
In an alternative embodiment, the data transmission module is further configured to:
the transmission medium moves along a plurality of the transmission paths;
when the transmission medium reaches a source node of a data packet to be transmitted, any data packet to be transmitted is packed and transmitted by the transmission medium;
when the transmission medium reaches any destination node of the data packet to be transmitted, the data packet to be transmitted is unpacked.
In the transmission process of the data packet to be transmitted, the transmission path may include other nodes besides the common transmission path. For other nodes than the common transmission path, when the transmission medium reaches each node, the respective data packets to be transmitted may be parsed to determine what operation is performed on the data packets to be transmitted. When the transmission medium reaches the source node of the data packet to be transmitted, the data packet to be transmitted is packed, when the transmission medium reaches the destination node of the data packet to be transmitted, unpacking is carried out on the data packet to be transmitted to finish transmission, and when the transmission medium reaches other transmission nodes except the source node and the destination node of the data packet to be transmitted, unpacking and repacking are carried out on the data packet to be transmitted.
In an alternative embodiment, the data transmission module is further configured to:
judging whether the current node is a destination node of another data packet to be transmitted, if so, unpacking the other data packet to be transmitted, and then packing the data packet to be transmitted; if not, directly packaging the data packet to be transmitted.
For example, as shown in fig. 3, the transmission medium moves along each transmission path, and when the transmission medium reaches the node A1, i.e., the source node of the data packet A1, the data packet A1 is packetized; when the transmission medium arrives at the node B1, i.e. the source node of the data packet B1, the data packet a1 is unpacked, and the data packet a1 and the data packet B1 are packed together and transmitted simultaneously; when the transmission medium reaches the node C1, unpacking the data packet a1b1, and packing the data packet a1 and the data packet b1 respectively; when the transmission medium reaches the node C2, unpacking and packing the data packet a 1; when the transmission medium reaches the node A2, namely the destination node of the data packet a1, the data packet a1 is unpacked, the transmission of the data packet a1 is completed, and when the transmission medium reaches the node B2, namely the destination node of the data packet B1, the data packet B1 is unpacked, and the transmission of the data packet B1 is completed.

For example, as shown in fig. 3, when the transmission medium arrives at the node C1 during the movement from the start point to the end point of the transmission path, the data packet a1B1 is unpacked, and the data packet B1 contains the address of the destination node A2, so that the data packet a1 can be resolved to continue to be transmitted to the node C2, and the data packet B1 can continue to be transmitted to the node B2, because the data packet a1 contains the address of the destination node A2. When the transmission medium reaches the node C2, unpacking the data packet a1, and because the data packet a1 contains the address of the destination node A2, the data packet a1 can be analyzed to continue to be transmitted to the transmission node A2, and the data packet a1 is unpacked; when the transmission medium reaches the node A2, unpacking the data packet a1, and analyzing that the data packet a1 reaches the destination node because the data packet a1 contains the address of the destination node A2, so as to finish the transmission of the data packet a 1; when the transmission medium arrives at the node B2, the data packet B1 is unpacked, and the data packet B1 arrives at the destination node after the data packet B1 contains the destination node B2 address, so that the transmission of the data packet B1 is completed.

if the data quantity of the data packet to be transmitted is larger than the capacity allowance of the transmission medium, delay packaging the data packet to be transmitted;
and if the data quantity of the data packet to be transmitted is smaller than or equal to the capacity allowance of the transmission medium, packaging the data packet to be transmitted.
The bandwidth of the transmission medium refers to the amount of data that can be transmitted at a fixed time (e.g., every clock), and the capacity of the transmission medium is equal to or less than the bandwidth. Because the capacity of the transmission medium is fixed, the data volume capable of being transmitted is fixed in one clock period, and in the transmission process of a plurality of data packets, the data volume of each data packet to be transmitted needs to be judged at each transmission node so as to enable the transmission process of each data packet to be transmitted to be smoothly carried out. For example, assuming that the data bit width of the data packet a1 is 4 bits, the data bit width of the data packet b1 is 4 bits, the data packet c1 is already packed at one node, and assuming that the data packet c1 is still required to be packed at the transmission node, the remaining capacity of the transmission medium is 2 bits, it is determined that the capacity of the transmission medium is insufficient, the data packet c1 cannot be packed, one clock cycle is delayed, and the data packet c1 is packed at the next clock cycle.
