The present exemplary embodiment will be described in detail below with reference to the drawings and examples.
First, the embodiments of the present disclosure provide a method for transmitting traffic stream data, which may be executed by any electronic device with computing processing capability.
Fig. 1 shows a flow chart of a method for transmitting service stream data in an embodiment of the present disclosure, and as shown in fig. 1, the method for transmitting service stream data provided in the embodiment of the present disclosure includes the following steps:
s102, monitoring the traffic flow data volume output by a first target port on the network equipment, wherein the network equipment comprises: and the first target port is any one port of the network equipment connected with the next hop equipment.
It should be noted that the network device may be a physical entity connected to the network. Alternatively, the network device in the embodiments of the present disclosure may be any one of a bridge, a gateway, a switch, a computer, and the like. The port can be a data outlet for communication and communication between the network equipment and the outside. Alternatively, a port in the embodiments of the present disclosure may be an interface in any network device, such as a bridge, a gateway, a switch, a computer, and the like, for connecting to another network device. The data amount may be the number of data or the size of the data capacity.
For example, the number of traffic streams output by a first destination port on the gateway is detected.
And S104, when the traffic flow data volume output by the first target port is higher than the preset threshold corresponding to the first target port, directing the key traffic flow transmitted by the first target port to a second target port, and transmitting the key traffic flow to a destination network through the second target port, wherein the second target port is a port on the network equipment, the traffic flow data volume of which is lower than the preset threshold corresponding to the corresponding port and is different from the first target port.
It should be noted that the traffic flow may be a data unit exchanged and transmitted in a network with deterministic requirements on latency. The critical traffic flow may be a delay deterministic traffic flow. For example, the traffic flow may be a message. The destination network may be a network address where the traffic flow is received.
For example, in one embodiment, a traffic flow is transmitted to a destination network through a first destination port, the number of data packets of an output queue length threshold (corresponding to the preset threshold) corresponding to the first destination port is set to be 1000, and at this time, when the number of data packets of the output queue length of a second destination port is detected by hardware in real time to be 200, when the number of data packets of the output queue length of the first destination port is detected by hardware in real time to be 1200 suddenly, a critical traffic flow (such as a delay-sensitive or packet-loss-sensitive traffic flow) transmitted by the first destination port is redirected to the second destination port, and is transmitted to the destination network through the second destination port.
Optionally, in an embodiment, the traffic flow is transmitted to the destination network through the first target port, the threshold of the first target port is set to be a packet loss occurrence (corresponding to the preset threshold), and when it is detected by hardware that no packet loss occurs at the second target port, the key traffic flow (such as the delay-sensitive or packet-loss-sensitive traffic flow) transmitted by the first target port is redirected to the second target port, and is transmitted to the destination network through the second target port.
Optionally, in an embodiment, the traffic flow is transmitted to the destination network through the first destination port, a port utilization threshold (corresponding to the preset threshold) of the first destination port is set to 90%, and at this time, the port utilization of the second destination port is detected to be 20%, when it is detected in real time by hardware that the port utilization of the first destination port is over 90%, the critical traffic flow (such as a delay-sensitive or packet-loss-sensitive traffic flow) transmitted by the first destination port is redirected to the second destination port, and is transmitted to the destination network through the second destination port.
S106, continuously monitoring the traffic flow data volume output by the first target port on the network equipment, and when the traffic flow data volume output by the first target port is lower than the preset threshold corresponding to the first target port, redirecting the key traffic flow directed to the second target port to the first target port, and transmitting the key traffic flow to the target network through the first target port.
For example, in one embodiment, the number of data packets continuously monitoring the length of the output queue of the first target port on the network device is 500, and the critical traffic data directed to the second target port is redirected to the first target port, and at this time, the critical traffic data is still transmitted to the destination network through the first target port.
Optionally, in an embodiment, when it is continuously monitored that the first target port on the network device has no packet loss event, the key traffic data directed to the second target port is redirected to the first target port, and at this time, the key traffic data is still transmitted to the destination network through the first target port.
Optionally, in an embodiment, when the port utilization of the first destination port on the network device is continuously monitored to be 50%, the critical traffic flow data directed to the second destination port is redirected to the first destination port, and at this time, the critical traffic flow is still transmitted to the destination network through the first destination port.
During specific implementation, the output port of the key service flow is dynamically adjusted according to the service flow data volume output by the port in combination with the preset threshold corresponding to the port, so that when the service flow data volume is increased suddenly, the key service flow is guaranteed not to be congested, and the service flow is quickly transmitted to meet the requirement of guaranteeing the time delay of the key service flow.
In an embodiment of the present disclosure, as shown in fig. 2, the service flow data transmission method provided in the embodiment of the present disclosure may redirect a transmission port of a key service flow through the following steps, so as to ensure a low latency requirement for transmission of the key service data:
s202, whether a parallel port exists in the network equipment is detected, wherein the parallel port is a port which is different from the first target port and is connected with the next hop equipment by the network equipment.
It should be noted that the parallel port may be a port through which data is transferred in a parallel manner on the network device.
For example, in one embodiment, the a device is connected to the B device through two ports, namely an X port and a Y port, which are parallel ports of the X port.
And S204, if the network equipment has a parallel port, determining the parallel port as a second target port.
In specific implementation, as shown in fig. 3, the traffic flow is transmitted from the network device PE1 to the network device PE2 through the network device P1 and the network device P2, and then is transmitted to the destination network by the network device PE 2. The network device P1 includes two parallel ports P11 (corresponding to the first destination port) and P12 (corresponding to the parallel ports) connected to the next hop network device P2, and selects a non-congested port P12 as a redirect port (corresponding to the second destination port) when an instantaneous congestion occurs at the P11 port (corresponding to a traffic flow amount output from the first destination port being higher than a preset threshold corresponding to the first destination port).
Through the embodiment, according to the service flow data volume output by the port and the preset threshold value corresponding to the port, when the port is congested, the output port of the key service flow is adjusted to be changed into the parallel port of the port, so that the low-delay requirement of key service data transmission can be ensured when the service flow data volume is increased suddenly.
In an embodiment of the present disclosure, as shown in fig. 4, in the traffic flow data transmission method provided in the embodiment of the present disclosure, congestion occurs to a port of a traffic flow and a parallel port does not exist for redirection, so as to reduce a time delay of the traffic flow due to the absence of the parallel port:
s402, if the network device has no parallel port, the neighbor port is determined as a second target port, and the neighbor port is a port of the network device connected with the neighbor device.
It should be noted that the above-mentioned neighbor device may be a physical entity in a network directly connected to a network device, and the neighbor device in the embodiment of the present disclosure may be any one of a router, a bridge, a gateway, a switch, a computer, and the like.
In an embodiment of the present disclosure, a traffic flow data transmission method provided in the embodiment of the present disclosure filters neighbor devices by the following steps: screening one or more neighbor devices meeting a first preset condition from the plurality of neighbor devices, wherein the first preset condition is as follows:
distance (N, D) < Distance (N, S) + Distance (S, D), where Distance (N, D) represents the Distance from the neighbor device N to the destination network D, Distance (N, S) represents the Distance from the neighbor device N to the present network device S, and Distance (S, D) represents the Distance from the present network device S to the destination network D.
In specific implementation, as shown in fig. 5, the traffic flow is transmitted from the network device PE1 to the network device PE2 through the network device P1 and the network device P2, and then is transmitted to the destination network by the network device PE 2. Network device P1 is connected to network device P2 without parallel ports, network device P1 has neighbor device P3 (equivalent to network device P3), neighbor device P6 (equivalent to network device P6), network device P7 is the next hop device of neighbor device P6, network device P4 is the next hop device of neighbor device P3, the latency between network device PE1 and network device P1 is 100ms, the latency between network device PE1 and network device P1 is 100ms, the latency between network device P1 and network device P1 is 200ms, the latency between network device P1 and network device P1 is 500ms, the latency between network device P1 and network device P1 is 300ms, the latency between network device P1 and network device P1 is 1000ms, the latency between network device P1 and network device P1 is 300ms, the delay between network device P2 and network device PE2 is 100ms, and the delay between network device P7 and network device PE2 is 300ms, at this time, a loop-free shortest path port (device) is calculated as a redirection port (device) by the following method (corresponding to the first preset condition): the neighbor device needs to satisfy the following condition that the loop-free neighbor device, the distance from the neighbor device to the destination network is less than the sum of the distance from the neighbor device to the network device and the distance from the network device to the destination network, and when the network device P1 to the network device P2 is instantaneously congested and becomes congested, the shortest path of the network device P1 except the neighbor device P2 needs to be calculated, wherein the neighbor device P3 of the network device P1 calculates the shortest path according to the above steps: the delay between the network device P3 and the network device P4 is 300ms, the sum of the delay between the network device P4 and the network device PE2 is 600ms, the sum of the delay between the network device P4 and the network device PE2 is 200ms, which is greater than the delay between the network device P3 and the network device P1, the delay between the network device P1 and the network device P2 is 200ms, and the sum of the delay between the network device P2 and the network device PE2 is 100ms, and the conditions of the loop-free neighbor devices are not met. The neighbor device P6 of the network device P1 calculates the shortest path according to the above steps: the sum of the time delay 300ms between the network device P6 and the network device P7 and the time delay 300ms between the network device P7 and the network device PE2 is 600ms, which is smaller than the sum of the time delay 500ms between the network device P6 and the network device P1, plus the time delay 200ms between the network device P1 and the network device P2 and the time delay 100ms between the network device P2 and the network device PE2, and 800ms, which satisfies the loop-free neighbor device condition, that is, the neighbor port between the network device P1 and the neighbor device P6 is determined as the second target port.
