Detailed description of the invention
Fig. 1 is a kind of step flow chart of video service node resource allocation methods of the present invention；
Fig. 2 is a kind of block diagram of video service node resource allocation system of the present invention；
Fig. 3 is the scene application schematic diagram in the embodiment of the present invention.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
With reference to Fig. 1, the scene of the present embodiment application is as shown in figure 3, mainly include videoconference client, service in the present embodiment
Node resource distributor and service node cluster include multiple service nodes in the service node cluster.The present embodiment mentions
A kind of video service node resource allocation methods supplied, specifically includes the following steps:
S1, periodically to each service node acquisition state factor information in service node cluster, and then calculate each
The state value of service node；
In the present embodiment, service node resource allocator, which periodically will start, adopts the state factor information of each service node
Collection, the state factor information include but is not limited to service connection number, the CPU idleness of host, memory surplus, disk
The indexs such as IO utilization rate, network I/O utilization rate.
S2, after service node resource allocator receives service request, according to the state value of each service node, choosing
The access method for the optimal service node selected out is back to videoconference client；
In the present embodiment, when service node resource allocator receives service request, service node resource allocator meeting
The state value of each service node is obtained, the state value of service node represents the service ability of the node, and it is more big, illustrate to take
Business ability is stronger.In addition the quality for guaranteeing service in the present embodiment, sets a minimum state threshold, is lower than this shape
The service node of state threshold value should not provide service again, and the service node that only state value is higher than state threshold can be just given to by selection
Videoconference client carry out using.
S3, videoconference client obtain Video service by the optimal service node returned.
The present embodiment by when distributing service node according to the various performances of each service node and host
State computation goes out the state value of each service node, so as to select most reasonable service node according to state value, reaches
The utmostly effect of load balancing, but also be effectively avoided that congestion and can more play the service ability of service node.
It is further used as preferred embodiment, the timing in the present embodiment is to each service section in service node cluster
Point acquisition state factor information, and then calculates the state value of each service node, the step for specifically include:
S11, periodically to each service node acquisition state factor information in service node cluster；
S12, regular processing is carried out to the state factor information that collects, obtain it is regular after state factor information；
In the present embodiment, since the original value unit of collected state factor information is different, the dimension of expression is different, needs
The various factors in state factor information are carried out regular.Compare for convenience and calculates, it is unified that each factor is regular for node
Remaining processing capacity X, value range 0-100.Regular if host CPU current idle rate is 80% is 80, memory
It is 50 that surplus 50% is then regular, and it is 92 that 40M/s utilization rate 8% is then regular in disk I/O utilization rate, and node pressure surveys highest carrying
Then regular current 50 tunnel of 500 tunnel Video services is 90 etc..It is also contemplated that the configuration to different hosts host is different, such as configure
The CPU residue of high host 30% may be more remaining than the CPU with the host 70% set low, and processing capacity is also eager to excel, so often
A machine has a configuration performance coefficient k, indicates that the host is directed to the performance multiple of benchmark host, value >=1.Consider
After configuring the coefficient of performance, it is final it is regular after the factor be kX.
S13, according to the state factor information after regular, the state of each service node is calculated by preset formula
Value.
It is further used as preferred embodiment, each factor in state factor information in the present embodiment includes
CPU idleness, memory surplus, disk I/O utilization rate, network I/O utilization rate and service connection number；For difference in the present embodiment
The factor, weight h is also different, and between 0-1, node state value (W) is defined as these state factors and multiplies and weight value
With, therefore the calculation formula of the state value are as follows:
W=h1*A+h2*B+h3*C+h4*D+h5*E；
Wherein, W indicates that state value, A indicate that CPU idleness, B indicate memory surplus, and C indicates disk I/O utilization rate, D table
Show network I/O utilization rate, E indicates service connection number, and h1 indicates the corresponding weight of CPU idleness, and h2 indicates that memory surplus is corresponding
Weight, h3 indicates the corresponding weight of disk I/O utilization rate, and h4 indicates the corresponding weight of network I/O utilization rate, and h5 indicates that service connects
Connect several corresponding weights.
Other factors such as node pressure can also be added in above-mentioned state factor information and survey highest bearing value etc. for the present embodiment
Etc. the factor information that can reflect service node process performance, so that the state value calculated reflects more accurate.
It is further used as preferred embodiment, asking in the present embodiment when service node resource allocator receives service
After asking, according to the state value of each service node, the optimal service node visit method selected is back to videoconference client,
The step for specifically include:
S21, after service node resource allocator receives service request, will according to the state value of each service node
The maximum service node of state value is as optimal service node；
S22, judge whether the state value of optimal service node is greater than or equal to preset state threshold, if so, will most
The access method of excellent service node is back to videoconference client；Conversely, then prompting without available service node.
Wherein, the state value of service node represents the service ability of the node, more big, illustrates that service ability is stronger.Separately
The quality for guaranteeing service in outer the present embodiment, sets a minimum state threshold, when the state value of optimal service node
When lower than this state threshold, indicates that service node should not provide service again, prompt without available service node, only state value
Higher than state threshold service node can be just given to by selection videoconference client carry out using.
