Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1, a method for uploading user-generated content based on cloud-edge collaboration provided in an embodiment of the present invention includes: s1, the user end transmits the content data to the preset edge node;
in some examples, selecting the preset edge node may be: by default, the ue temporarily transmits UGC (User Generated Content) to the nearest edge node, and the UGC Content is Content that does not need to be transmitted in real time. Since the edge nodes are close to the clients and the non-real-time content upload requests are usually distributed, the edge nodes can provide fast temporary content upload services for the nearby clients in most cases. When a user side finds that the cache of the nearest edge node is insufficient, corresponding content uploading requests are sent to other adjacent edge nodes; when all nearby edge nodes refuse service due to insufficient cache, the content is directly uploaded to the target platform server according to the conventional method, which may be a Transmission Control Protocol (TCP) Transmission method.
And S2, caching the content data by the preset edge node, and uploading the content data to the target server according to the preset logic link in the main edge relay route corresponding to the preset edge node.
In some embodiments, as shown in fig. 3, obtaining the primary edge relay route may be: after the content data sent by the user side is cached by the adjacent edge node, the cloud center judges whether the available relay route of the main edge of the edge node exists or not according to the service uploading requirement, namely whether the existing relay route of the main edge can meet the current content uploading condition or not. If so, continuing to transmit the content by using the route; otherwise, the cloud center calculates a main edge relay route for the adjacent node according to the uploading condition, issues the route to each relevant node, and uploads the cached content data to the corresponding target server by using the idle network bandwidth. The service uploading requirement may include: bandwidth, delay, packet loss rate and the like.
In some embodiments, a preset logical link in the primary edge relay route may be constructed according to the avoidance level of the logical link. Calculating the avoidance ranking may include: carrying out avoidance grading on the logical links according to the sharing degree of the physical links, wherein the lowest avoidance grade is grade 1 and is initially set to be 0; the routing weights of each evasion class are equal. When the shortest path first selection strategy is adopted, the following characteristics are satisfied: if and only if the path cannot be composed of logical links with low avoidance levels, the logical links with high avoidance levels are used to dynamically construct a shortest path from the edge node to the target service end, wherein the endmost path can be measured by the avoidance levels of the logical links, and the lower level links are preferentially selected, and the calculation process can include:
when the sharing degree lambda (i) of the physical link with the constraint bottleneck of the logical link i is equal to the maximum sharing degree in the existing logical link set L, the logical link i is associated with the avoidance level p (i, L) of the L:
p(i，L)＝λ(i)＝max{λ(j)|j∈L}
when the sharing degree lambda (i) of the physical link with the constraint bottleneck of the logical link i is smaller than the maximum sharing degree in the existing logical link set L, the logical link i is associated with the avoidance level p (i, L) of the L:
wherein,
wherein, L is the existing logical link set and is initially an empty set; λ (j) is the bottleneck physical link sharing degree with constraint, where the logical link j is associated with L, and is expressed as the number of times that the logical link j appears in other main edge relay routes; and MaxP is the maximum value of each link avoidance grade in L. If the physical link i is used as a logical link of the main edge relay route of the current node, the link sharing degree of the link i associated with the L is added with 1, and the scheme is favorable for controlling the highest physical link sharing degree of the logical links in the path.
In some examples, when a certain edge node has a UGC upload demand, if there is no main edge relay route in L, dynamically constructing a shortest main edge relay route thereof, and storing a corresponding physical link in L as a logical link; when an edge node finishes all UGC transmission on the edge node, the related logical link is deleted in L.
In some examples, it may further include: and presetting edge nodes, uploading all UGC contents to a corresponding target server, and deleting a main edge relay route, thereby releasing occupied storage resources and improving the sharing degree of a link.
According to the scheme, the edge computing and cloud computing capabilities are fully utilized, the content data transmitted from the user side to the preset edge node is not required to be successfully uploaded to the target server side, and the user experience is remarkably improved; the content data are uploaded to the target server through a preset logic link in the main edge relay route corresponding to the preset edge node, a new network bandwidth utilization optimization space is provided by the main edge relay route of the edge node, the pressure of conventional transmission is relieved, and network congestion can be greatly avoided. Preferably, in any of the above embodiments, before S2, the method further includes:
s21, the preset edge node distributes a main edge relay route corresponding to the uploading condition of the content data through the cloud center;
s22, the cloud center constructs the preset logic link in the main edge relay route according to the link avoidance level. The uploading condition may include bandwidth, delay, packet loss rate, and the like.
In one embodiment, the edge nodes and the non-real-time content uploading historical information can be managed through the cloud computing platform, and management work can be achieved based on the edge layer network information base and the uploading activity information base. The edge-layer overlay network refers to an overlay network composed of edge nodes and logical links between the edge nodes, and the edge-layer overlay network information includes edge node information, distances between the edge nodes, related topology information, and the like, wherein the distances between the edge nodes may be measured by using measured delays, and the topology information may include a topology structure of the edge nodes. The inter-edge node distance may be obtained by sending a probe packet. And the uploading activity information base records the non-real-time content uploading condition. According to the stored non-real-time content uploading historical information, the cloud center analyzes and predicts non-real-time content uploading demand characteristics so as to construct a performance-optimized non-real-time content uploading structure according to the demand characteristics, wherein the demand characteristics can comprise: bandwidth, delay and packet loss rate, and the like, as well as some conditions required during uploading; the upload structure is a structure representing a main edge relay route.
The main edge relay route can be the edge relay route except the part from the user side to the nearest neighbor edge node, and the scheme is mainly based on the dynamic construction process of the main edge relay route. And the main edge relay route is distributed in a centralized manner through the cloud center, and a link in the main edge relay route is constructed by utilizing the avoidance grade of the logical link. To avoid the invalid non-real-time content upload structure occupying storage resources, if a single built non-real-time content upload structure is not used within a specified time, it is destroyed to free up occupied storage space.
According to the scheme, a performance-optimized non-real-time uploading main edge relay routing structure is constructed according to the uploading condition of the content data of the user, a new network bandwidth is provided to achieve the uploading of the content generated by the user, and the highest physical link sharing degree of the logical link in the control path is facilitated through the logic link determined by avoiding the grade.

It should be noted that, the third party requesting end may be a platform for the user end to finally upload the content data, for example: and uploading the video data edited by the user to a tremble platform.
In some examples, the emergency mechanism may further include: when a third party requests content which is not completely uploaded, the target server side sends the received content to the third party, and when the sending rate is higher than the content uploading rate and the data volume of the received content cannot counteract the negative influence of the rate difference, namely the sending rate of the target server is larger than the receiving rate and the rate difference cannot counteract the received content, the edge node of the cache content is informed to send the remaining content to the target server by conventional TCP transmission so as to improve the non-real-time content uploading transmission. The sending rate refers to the rate of sending data to the third party by the target server, and the uploading rate refers to the rate of uploading data to the target server by the edge node of the cache content.
According to the scheme, when the request data of the third-party request end is not completely uploaded, the content data cached in the preset edge node is uploaded to the server in a TCP mode, the conventional TCP is adopted to control the transmission rate from the user to the nearby edge node, when the relay route fails to successfully upload the request data, the emergency is realized through TCP transmission, the third-party request end does not need to wait too long time due to the fact that the complete uploading is not successful, and the transmission efficiency of the non-real-time content uploading is guaranteed. Preferably, in any of the above embodiments, S21 specifically includes:

Wherein, the uploading condition may include: bandwidth, delay, packet loss rate and other conditions required for uploading,
in some examples, the cloud center calculates the main edge relay route that satisfies the conditions according to the bandwidth, delay and packet loss rate conditions. For example: a user end needs to upload certain data content, wherein the bandwidth condition is set as follows: 100 bits +/-10 bits, delay within 10ms, packet loss rate within 1%, according to the above conditions, comparing data in the existing main edge route to obtain the main edge route with bandwidth higher than 110 bits, delay less than 10ms and packet loss rate within 1%, if calculating a plurality of satisfying conditions, selecting the main edge route satisfying various conditions and having the best packet loss rate.
