There is very big difference with the scene of traditional P2P technical application due to being broadcast live, traditional P2P technology is mainly used in
The scene (such as video resource downloading of the websites such as video on demand) of shared video or audio data, compared to above-mentioned scene, directly
It broadcasts and there are the characteristics that having all the time a large amount of user to pass in and out direct broadcasting room, so that the P2P network moment based on live streaming is dynamic
State variation, and change frequency is exceedingly fast, but this is for real-time, and the live scene extremely low to delay Caton tolerance rate
It is unacceptable, so how to establish the P2P network of suitable live scene becomes urgent problem to be solved.
In order to solve the above-mentioned technical problem, the embodiment of the present application provide it is a kind of establish the P2P network based on live streaming method,
Device, equipment and storage medium.Parameter Map 2 is a kind of method for establishing P2P network that the embodiment of the present application illustrates
Flow chart, the method includes the steps:
Client executing S210 is broadcast always: after entering a direct broadcasting room, other in the corresponding P2P network of Xiang Suoshu direct broadcasting room
Node sends connection request；
S220: connection is established with the node for responding the request；
S230: the number of nodes that record has connected with this live streaming client；
S240: when the number of nodes having connected with this live streaming client is less than preset value, again to the direct broadcasting room pair
Node in the P2P network answered sends connection request.
In some instances, described to enter a direct broadcasting room, it specifically may is that user clicks to enter the control of the direct broadcasting room
Afterwards, into the direct broadcasting room.
In some instances, after live streaming client sends connection request to other nodes in P2P network, request is received
Other nodes can be according to selecting returning response or to be not responding to the case where itself, if live streaming client receives the sound of node return
It answers, is then successfully established connection, if live streaming client does not receive always response before the deadline, then it is assumed that connection failure.
In one specific example, the method for P2P network of the foundation described in Fig. 2 based on live streaming may is that a direct broadcasting room a
In have several spectator clients, after these spectator clients mutually establish P2P network, be broadcast live pushing away for stream medium data
It send.It broadcasts always when client 1 logs in server registration, and after entering direct broadcasting room a, into the corresponding P2P network of direct broadcasting room a
Node send connection request, certainly, live streaming client 1 can by enter direct broadcasting room a after, to server request direct broadcasting room a
Each address of node information so that live streaming client 1 can send connection to the node in the corresponding P2P network of direct broadcasting room a
Request；When be broadcast live client 1 receive the response of node after, after establishing connection with the node, more new record with live streaming client
The number of nodes that end 1 has connected, if there is the node connection that connection has been established to disconnect certainly, the number of nodes also being had connected described in update
Amount, and when the number of nodes having connected with live streaming client 1 is less than preset value, again to the corresponding P2P of the direct broadcasting room a
Node in network sends connection request, presets so as to keep the quantity of the node of connection to be no less than first with live streaming client a
Value, such as: preset value 2, live streaming client 1 and 3 node have connected, respectively node 1, node 2 and node 3, and from section
Point 1 obtains live broadcast stream media data, but since the two of them node of network jitter or node 2 and node 3 exits direct broadcasting room,
Connected node quantity is equal to 1, and less than 2, at this point, if being not processed, if node 1 also exits direct broadcasting room or because network is trembled
The reasons such as dynamic do not receive live broadcast stream media data, and live streaming client needs the node again into P2P network to request connection, such as
This, which may cause, does not receive live broadcast stream media data for a period of time, and makes that client a broadcasting live broadcast stream media data are broadcast live
When exist time or Hua Ping, and the embodiment of the present application by maintenance with live streaming client a keep connect number of nodes it is no less than pre-
If value, it is ensured that client a is when that can not obtain live broadcast stream media data for live streaming, quickly obtain live streaming from the node having connected
Stream medium data reduces the time for re-establishing connection, reduces delay and Caton, admirably adapts to higher to requirement of real-time
Live scene.
In some instances, step S230 described in reference Fig. 3 a, Fig. 2 can specifically include:
S231: the node identification having connected with this live streaming client is stored to a buffer area.
S232: signaling information periodically is interacted with the node having connected, the signaling information of connected node is discontented if it exists
Sufficient preset requirement then discharges the node identification of the buffer area storage.
S233: the quantity for the node identification stored in the buffer area is periodically recorded.
The buffer area can be queue, for safeguarding the node identification of storage.The node identification is for characterizing the P2P
The uniqueness of nodes, for example, No. IP of node or other.
The signaling information includes: the information such as the upstream bandwidth of network speed, time delay, packet loss and/or the node having connected, can
To be wherein one or more signaling message comprehensive scores, the preset requirement that meets refers to the small Mr. Yu of above-mentioned comprehensive score
A preset fraction.Except of course that scoring is also possible to discovery when this live streaming client interacts signaling information with connected node, when
Prolong greatly or when packet loss is extremely low or the upstream bandwidth of connected node is smaller, can in connection breaking, and by the node
Mark from buffer area discharge.
Fig. 3 a the embodiment described records the number of nodes having connected with this live streaming client by way of queue, can be with
The preferably node that has connected of maintenance and management and this live streaming client.
In certain some examples, the number of nodes having connected can also be cached with buffer area, after disconnecting, reduced slow
The number of nodes that area has connected is deposited, after newly establishing connection, increases the number of nodes that buffer area has connected.In other example
In, it can be periodically detected the number of nodes having connected, and record the number of nodes having connected with this live streaming client.It can be with
The number of nodes being had connected using other way record with this live streaming client, the application do not limit record and this live streaming client
The mode for the number of nodes having connected.
Number of nodes in the corresponding P2P network of one direct broadcasting room is huge, if each live streaming into direct broadcasting room is objective
Family end will send connection request to whole nodes, be bound to cause the excessive of bandwidth and occupy.It is some in order to solve the technical problem
In example, referring to Fig. 3 b, step S210 described in Fig. 2 be can specifically include:
S211: client is broadcast always (such as after live streaming client a) enters a direct broadcasting room, to server requesting node column
Table.
Node listing is sent to live streaming client a according to the relevant information of the live streaming client by server.
Wherein, the address of node information for meeting preset condition, such as IP address etc. are carried in the node listing.
The uplink energy that the preset condition respectively saves in the location information, P2P network according to equipment where this live streaming client a
The hardware configuration determination of power, connection, Network status and/or place equipment.In one specific example, server is according to institute
The location information of equipment, will exist apart from the closer a certain number of nodes records of live streaming client where stating live streaming client
In node listing, quantity can be 40 to five ten.
S212: after the live streaming client receives the node listing, the node in Xiang Suoshu node listing sends connection
Request.
In some instances, live streaming client a can be according to the address information carried in node listing, into node listing
All or part of node send connection request.
The embodiment of the present application is by obtaining the node column for meeting preset condition for this live streaming client a from server
Table combines the quality of connection to control the quantity that this live streaming client a sends the node of connection request.
It finds in practical applications, saturated phenomenon easily occurs in existing P2P network, and makes the node newly to network can not
Resource data is obtained from other nodes.For example, referring to Fig. 4, node 1,2 and 3 resource data supplier and number of resources each other two-by-two
According to taker is obtained, the resource data supplier that such as each node is at most used as two nodes, then when there is new node to enter, section
Point 1,2 and 3 can not provide resource data to the node newly entered.For this problem, the P2P network that the embodiment of the present application proposes
In, other number of nodes that any node is actively connected are not more than the first given threshold, other sections that any node actively connects
Points are not more than the second given threshold, and first given threshold is greater than the second given threshold.
It is the P2P network diagram shown in the embodiment of the present application referring to Fig. 5 a, in P2P network described in Fig. 5 a, setting is appointed
Other number of nodes that one node is actively connected are not more than the first given threshold, other number of nodes that any node actively connects are not
Greater than the second given threshold, and first given threshold is greater than the second given threshold, such as the first given threshold is 3, second
Given threshold is 2, and 1 active of node establishes connection with 2 nodes, is actively connected by 3 nodes, then node 1 is actively connected
Other number of nodes be 3, be equal to the first given threshold, other number of nodes that node 1 actively connects be 2, be equal to second setting threshold
Value, at this point, node 1 can not actively connect other nodes, also successfully can not actively be connected by other nodes；2 active of node connects
1 node is connect, is actively connected by 2 nodes, then other number of nodes that node 2 is actively connected are 2, less than the first setting threshold
Value, other number of nodes that node 2 actively connects are 1, less than the second given threshold, at this point, node 2 can also actively be connected as 2-
1=1 node, node 2 also allow actively to be connected by 3-2=1 other nodes.
So far, so far, in the P2P network proposed different from the construction method of traditional P2P network, the embodiment of the present application,
Other number of nodes that any node is actively connected are not more than the first given threshold, other number of nodes that any node actively connects
No more than the second given threshold, and first given threshold is greater than the second given threshold.That is, in the embodiment of the present application
The number of nodes (the first given threshold) for connecting the permission of each node actively, which is greater than, allows actively to connect other number of nodes (the
Two given thresholds) so that no matter how entire P2P network is set up according to the method for the embodiment of the present application, certainly exist by other
The chance that node actively connects finally makes new so that can not be saturated by the P2P network that the embodiment of the present application is set up
The node of addition can be easier in access P2P network.For example, referring to Fig. 5 b, for having 3 nodes in P2P network, respectively
It is node 1, node 2 and node 3, in the P2P network, the first given threshold is 2, and the second given threshold is 1, i.e., each node is permitted
Perhaps actively other number of nodes of connection are 1, other number of nodes for allowing actively to be connected are 2.If 1 active connecting node 2 of node,
So node 1 reaches the second given threshold, and node 1 can not actively connect other nodes, but can actively be connected by 1 node
It connects；At this point, node 3 can active connecting node 1 the case where perhaps node 2 is due to 3 active connecting node 1 of node or node 2
It is similar, in order not to repeated description, as signal by taking 3 active connecting node 1 of node as an example in Fig. 5 b, at this point, node 1 and 3 reaches
To the second given threshold, other nodes can not be actively connected, but can actively be connected by 1 node, P2P network at this time
In, node 2 can actively connect 1 other node, since node 1 and 2 has built up connection, so, node 2 is main to node 3
It is dynamic to send connection request, it completes the foundation of P2P network to node 1-3 at this time, in the P2P network, can be led without any node
Other nodes of trend send connection request, and 3 nodes can actively be connected by other nodes.When node 4 enters the P2P network
When, since the node 1-3 in the P2P network can not actively connect other nodes, so, by the node 4 for newly entering the P2P network
Into node 1-3, any node sends connection request (such as 4 active connecting node 2 of node shown in Fig. 5 b), to establish newly
P2P network.It can be seen that the method by the embodiment of the present application from the example of Fig. 5 b, and no matter the connection between node 1-3 is closed
How is system, and the chance for allowing actively to be connected by other nodes there are 3 in entire P2P network, network will not be saturated；And
Node 4 be added after new P2P network in, node 1 and node 3 can permit actively to be connected by 1 node, node 4 then by
Allow actively to be connected by 2 nodes, there is also 4 permissions for new P2P network by the chance of other nodes active connection, will not
It is saturated.
It is not more than the first given threshold, Ren Yijie based on other number of nodes that in P2P network, any node is actively connected
Other number of nodes that point actively connects are not more than the second given threshold, and first given threshold is greater than the second given threshold.
It in some instances, can be according to the address information on node listing, to node listing after live streaming client receives node listing
On all or part of node send connection request, receive request node judge itself whether also allow by other nodes actively
Connection, if other number of nodes that the node is actively connected are given live streaming client returning response, then connected less than the first given threshold
It is connected into function, if being equal to the first given threshold, returning response, live streaming client do not receive feedback before the deadline, then
Think connection failure.
It is the flow chart for another method for establishing P2P network that the embodiment of the present application is schematically shown, specifically referring to Fig. 6
Step includes:
S610: the live broadcast stream media data of acquisition are sent to server by main broadcaster's client.
S620: the live broadcast stream media data received are cut into several data packets by server, and each data packet is pressed
It is encapsulated according to customized format, includes first identifier in the customized format, first identifier is for describing each data packet
Uniqueness.
S630: with main broadcaster's client after the spectator client of same direct broadcasting room establishes P2P network, server is by institute
State node of the packet delivery to Subscriber in P2P network of encapsulation.
S210: live streaming client enters the direct broadcasting room, other nodes hair in the corresponding P2P network of Xiang Suoshu direct broadcasting room
Send connection request.
In some examples, in the P2P network, other number of nodes that any node is actively connected are no more than the first setting
Other number of nodes of threshold value, any node actively connection are not more than the second given threshold, and first given threshold is greater than the
Two given thresholds；
S220: the live streaming client and the node for responding the request establish connection, to update the P2P network.
S230: the number of nodes that the live streaming client record has connected with this live streaming client；
S240: when the number of nodes having connected with this live streaming client is less than preset value, again to the direct broadcasting room pair
Node in the P2P network answered sends connection request.
Method described in Fig. 6 be different from traditional P2P mode, first by live broadcast stream media data be cut into data packet without
It is blocks of files, the size of blocks of files may be in KB up to a hundred, and for blocks of files, and the cleavable granularity of data packet is smaller,
It can be used as smaller transmission unit to transmit in a network, such as when considering the size of the data packet after cutting, can combine
The transmission characteristic of Internet designs so that in the size of data packet and P2P network each interface channel transmission bandwidth
Match.For example, the channel established between each peer node can be UDP channel, and the size of each data packet can be the left side 1KB
The right side is slightly less than MTU (Internet layer maximum transmission unit), in this way, each data packet can be transmitted by 1 IP packet, is not required to
Occur unpacking based on IP packet, therefore the mode than cutting file is more efficient, so that having widely applicable scene.
The server that the embodiment of the present application proposes can be undertaken by a variety of entities, this depends on designer and sets to heterogeneous networks
Standby Partition of role.For example, Fig. 7 a, Fig. 7 b, Fig. 7 c are the network architectures under three kinds of different scenes, it can be seen that different business
Under mode, since business or the demand of equipment management are different, above-mentioned server can be undertaken by different types of server apparatus
Function.In Fig. 7 a, first server undertakes the role for collecting live broadcast stream media data, and second server undertakes cutting data packet
Role, third server is as the role to peer node packet distribution.In Fig. 7 b, first server is integrated with collection stream

Node, but not yet establish connection.
Live-vertex refers to that connection has been established with this node from both candidate nodes and keeps the node of connection status.It is living
Signaling information, such as packet loss, delay, network speed and/or upstream bandwidth can be periodically interacted between jump node and this node
Deng.
Transmission node refers to the node that can be used for obtaining resource data in the live-vertex.
Node is eliminated, refers to node second-rate in live-vertex, and being abandoned by this node active release.
Ossified node can be divided into two kinds, and one of which is connection to be requested in both candidate nodes, but be not connected with successfully section
Point；Another kind is in transmission node, can not transfer resource data node, it is such it may be the case that crash or suspension caused by.
Certainly, if data packet is grouped according to number, in some instances, transmission node may include ordering in P2P network
Node is read, for example, node 1 obtains 1 work song stream from node 2, node 2 is the corresponding subscription node with 1 work song stream of node 1, node 1
0 work song stream is obtained from node 3, node 3 is the corresponding subscription node with 0 work song stream of node 1.
In certain some examples, the step S230 of Fig. 2 is also possible to by that can safeguard a queue, active for recording
Node, when existing, when eliminating node and ossified node, by the superseded node and ossified node revocation in live-vertex, and working as should
