Detailed description of the invention
With reference to the accompanying drawings the present invention is described more fully, the example of the present invention is wherein described
Property embodiment.
Fig. 1 illustrates the flow chart of the network-building method of one embodiment of the invention.As it is shown in figure 1, should
Method specifically includes that
Step 100, registrar obtains the discharge pattern information of client, wherein, class of traffic
Type includes flow-sensitive type and non-flow sensitive kind.
In one embodiment, the live broadcast system of P2P networking mode composition is by registrar
(RegisterServer), content server (ContentServer) and client (Client)
Composition.Wherein, content server is responsible for providing Media Stream to client, and content server processes
From the connection request of client.After client connects upper content server, content server is by working as
Front progress is sent to client Streaming Media.Registrar is responsible for recording the state of client, and
Father node, establishment, maintenance and management whole P2P transmitting network is distributed for client.
In one embodiment, all clients can be divided into flow-sensitive node and non-flow is quick
Sense node two class.Flow-sensitive node refers to the node being unwilling to consume excess bandwidth, and flow-sensitive saves
Point is not intended to participate in media and flows to the propagation of other nodes.Non-flow sensitive nodes is then to flow consumption
Insensitive, it is ready to contribute self whole bandwidth, the propagation of Streaming Media can be participated in.
Step 102, registrar is with content server as tree root, with non-flow sensitive kind visitor
Family end is set up as branch point or leaves and is propagated tree, and flow-sensitive type clients connects by propagating tree
Receive data.
In one embodiment, flow-sensitive type clients is from using content server as tree root
Propagate the non-flow sensitive kind client in tree and receive data, but not as the joint propagated in tree
Point.
In one embodiment, propagate tree composition at least two backbone network, propagate the joint in tree for many
Point has unique father node in the backbone network that it is affiliated, also has at least another one backbone network
There is father node.Now, propagating a certain node in tree and can obtain data from multiple father nodes, this can
Think that the client of non-flow sensitive kind provides the most double propagation route and inlet flow, it is provided that
The transmission of double redundant data, can improve the stability of whole network.
In one embodiment, backbone network is propagated tree by many and is constituted, and the root node of tree is directly from interior
Hold server and obtain Media Stream.Propagate tree and ensure that node always has a propagation that can trace back to root
Route, so can avoid the occurrence of passive winding.
The network-building method of the embodiment of the present invention, for the feature of mobile interchange network users, devises one
Kind of P2P networking plan, when client adds live, distinguishes the discharge pattern of client, according to
The discharge pattern at family carries out networking: specifically utilizes non-flow sensitive users to build and propagates tree, undertakes biography
Broadcast task, make full use of its upstream bandwidth；Flow-sensitive user receives data from propagation tree, but
Not as tree interior joint, it is not necessary to other people propagation data, as such, it is possible to guaranteeing smooth playing
Flow sensitive users is not caused unnecessary flow consumption simultaneously.
Fig. 2 illustrates the structural representation of the P2P networking of one embodiment of the invention, such as Fig. 2 institute
Showing, the live networking of this P2P is with content server 200 as tree root, and this networking includes two by non-streaming
Backbone network i.e. backbone network A and backbone network B, backbone network A and B that amount sensitive nodes is constituted are responsible for
The propagation of Streaming Media, includes multiple node, i.e. node with backbone network B in backbone network A
202～node 221, backbone network interior joint is non-flow sensitive kind client, and each node is permissible
Forming a propagation tree with content server as tree root, non-flow sensitive kind client is as this
Branch point or the leaves of propagating tree are set up and are propagated tree.Flow-sensitive client such as node 222, joint
Point 223, node 224, not as the node propagated in tree, only obtain number from the node propagated tree
According to, node 216 that such as node 223 forms with non-flow sensitive client end～node 219 are as father
Node, realizes information by node 216～node 219 and content server mutual.
In one embodiment, non-flow sensitive kind client is at the first backbone network such as backbone network A
Having a father node, the father node from the first backbone network obtains complete data stream；Non-flow
Sensitive kind client has N number of father node, from second at the second backbone network such as backbone network B net
Obtaining the data stream of 1/N in each father node in backbone network, wherein, N more than or equal to 1 is just
Integer.As such, it is possible to the client of non-flow sensitive kind provides double propagation route and input
Stream, improves the stability of network.
In one embodiment, non-flow sensitive kind client can be set at the second backbone network such as
Backbone network A has a father node, has N number of father joint at the first backbone network such as backbone network B
Point, non-flow sensitive kind client obtains the number of 1/N in each father node from the first backbone network
According to stream, wherein, N is the positive integer more than or equal to 1.
Backbone network A and backbone network B the two backbone network are reciprocity.At non-flow sensitive kind
When client joins networking, both non-flow sensitive kind client can be assigned to backbone network
A, it is also possible to this client is assigned to backbone network B.If judging, obtaining client is that non-flow is quick
Sense type clients, selects a backbone network non-flow sensitive kind client to be added, during selection
The nodes as far as possible keeping two backbone networks is close.
In one embodiment, the node in backbone network is properly termed as backbone node, and backbone node exists
Backbone network only one of which father node (tree construction) at its place, but at another backbone network, permissible
There is N number of (N > 1 or N=1, can be pre-configured by system) its net father node.Each
Its net father node is only responsible for providing it the data of N/mono-, in the case of not considering packet loss,
These data sets constitute complete data stream altogether.Reduced single node by subdivided data stream
Dependence, and be conducive to making full use of the upstream bandwidth of node.Backbone node saves from Home Network father simultaneously
Point obtains complete data stream.Thus, backbone node obtains complete matchmaker from two backbone networks respectively
Body stream, the data that it receives are double redundancies, reduce packet loss, improving stability.
The node of flow-sensitive is added without backbone network, but can obtain Media Stream from backbone network, uses
The mode of many father nodes subdivided data stream, i.e. flow-sensitive node have N number of father in two backbone networks
Node, each father node is responsible for providing it the data of N/mono-.
An embodiment, non-flow sensitive nodes specific discharge sensitive nodes has flow more preferably to obtain
Weighting.System monitoring backbone network node adds the cost (average number of attempt) of father node, treats as
Originally reach default threshold values, then notice is recently joined live a collection of flow-sensitive node, allows them
Reduce father node number, until the cost monitored returns to below threshold values, just allow flow-sensitive
Node adds father node.
The P2P live broadcasting method of embodiment of the present invention offer and group network system, flow-sensitive user such as press
The user of charge on traffic, it is not necessary to worry oneself to need to pay for unnecessary flow consumption, be more suitable for
Current mobile interchange network users, and double input road can be provided for the child node that is newly added
By and inlet flow.
In one embodiment, with reference to Fig. 2, backbone network A and backbone network B with content server it is
Tree root, wherein, backbone network A and backbone network B can be made up of many trees, such as backbone network A
Holding multiple branches composition tree network that server is tree root within can being, backbone network B can be
Multiple branches composition tree network with content server as tree root, it may be said that backbone network A and backbone
Net B forms one with content server for tree root and propagates tree, it may also be said to this P2P networking is by many
The propagation tree composition of node composition, is only the difference called, has no effect on the reality of concrete scheme
Existing.
In one embodiment, the propagation tree of non-flow sensitive kind client composition can be one
R unit tree, r is the positive integer more than or equal to 2, and i.e. in this propagation tree, a father node has r
Child node, so, a father node can be to r sub-node-node transmission data.
In one embodiment, when networking, in addition to content server, in backbone network each
Node can You Liangge branch, that is this propagation tree is a binary tree.Band in view of node
Wide uneven, select binary tree to it is advantageously ensured that stability, when algorithm for design and implementation
It is easier to realize.It is to be understood that in actual applications, can be according to the band of propagating contents
Wide demand and real network bandwidth conditions arrange this propagation tree.For example, it is possible to by each father node
Child node number be fixed as a certain numerical value such as 2,3,4 etc., i.e. system be pre-configured with arrange lid pass
Broadcast tree.
In one embodiment, in a backbone network, if a father node can have up to 2
Bifurcated (is spent), and the client first being newly added is linked into the upper strata father node near tree root, when leaning on
The when that the father node out-degree of nearly tree root reaching predetermined value such as 2, node layer accesses still further below.
In one embodiment, each bifurcated number can be the fixed value being pre-configured with, and is choosing father
Can not also consider near tree root person preferential during node, to father node selection strategy, we do not limit
Fixed, if realizing, give an identical candidate priorities can to all new nodes, if
Connection failure occurs just priority fall first-class, of this sort dynamic approach.Because user exits directly
It is random for broadcasting, so the node near tree root person may not be the most always near tree root, if its father saves
Point exits live, after it reacquires father node, it is possible to just become far from tree root.
The network-building method of the embodiment of the present invention, the client for flow-sensitive type provides the most double
Propagation route and inlet flow while, increase network transmission stability, lower network complexity
Degree and time delay, and the motility of networking is higher.
P2P flow medium live system can be divided into tree-shaped and reticular system by its networking mode.Its
In, under tree, data block is passed to child node by father node, successively pushes, and networking is simple,
Route is clear；Under network structure, a number of neighbor node of each node maintenance, Lin Jujie
By periodically exchanging metadata learns whether there is the number oneself needed on other nodes between point
According to, the more final source of selected data.But, the P2P networking of tree is to network jitter very
Sensitivity, and there is the problem that can not make full use of Internet resources；Cancellated P2P networking is relative
Complexity, time delay is high, and stability does not also ensure.
The network-building method of the embodiment of the present invention, is different from traditional tree network and network structure net
Network, is extended traditional tree network, defines a kind of new tree-shaped Infrastructure mesh
Structural network, it is possible to achieve each node at least two groups of independences can trace back to content server
Distribution link, one group from its own place backbone network, another group from another backbone network, this
Plant Redundancy Design and can reduce packet loss, reduce the dependence to single node, improve stability, fall
Low network jitter is on the live impact brought；And the networking structure of the embodiment of the present invention is relatively
Simply, route is the most clear, it is possible to merge tree network and the advantage of network structure network；And add
Entering live client can select the father node that bandwidth is high to add according to band preference, reduces live
The time delay of stream.Relatively and prior art, if only one of which backbone network, if only setting propagation, that
Want father node logout, after all child nodes just lose data source；According to netted propagation, just deposit
At complicated network management problem, such as: how to avoid being formed between node isolated closure, use
One of benefit of network-building method of the embodiment of the present invention is can streamlining management, raising stability.
In one embodiment, during inter-node communication, Media Stream carries out being divided into chronologically can be
The data block of distribution in one IP bag, and use integer coding data block successively.Father node uses
Udp protocol sends data block to child node.Father node first carries out duplicate removal after receiving data block, so
After by data block forward give child node.In the reference time delay specified, if there being data block also not have
Receiving, child node can notify that father node resends this data block；Time delay is more than a specified time then
It is judged to packet loss, abandons retransmitting and attempt.
So, the network-building method that the embodiment of the present invention provides can be in conjunction with tree-shaped and cancellated excellent
Point, and have employed the technology that Media Stream is carried out band segmentation so that communication network is more stable.
With reference to Fig. 2, in one embodiment, node 209 has father at its affiliated backbone network A
Node 203, has father node 204,205,210,211, node in its net i.e. backbone network B
209 can obtain complete data stream from the father node 203 of backbone network A, can be from backbone network
The father node 204,205,210,211 of B obtains the data stream of 1/4, so, node 209
Data can be obtained, it is thus achieved that double redundancy during data by two paths.
If the father node of node 209 203 is because fault or other reasons exit this P2P networking, that
Owing to node 209 can also obtain complete data stream from its net father node, the most do not affect node
The use of 209 users, does not interferes with node 216 and the web-cast communication of node 217 yet.
If it is live that registrar detects that father node 203 exits, the most again distribute father joint for node 209
Point, can be set to content server 200, or the father by node 209 by the father node of node 209
Node is set to node 208, and the father node of node 208 is set to content server 200.
If any one of the father node 204,205,210,211 that node 209 is in backbone network B
Exitting network live, the data also not interfering with node 209 are transmitted, ibid, if registrar
Detect that a certain father node that its node 209 is netted at it exits live, then in backbone network B again
Distribute for node 209 or add father node.
In one embodiment, bandwidth demand and/or real network bandwidth according to propagating contents are joined
Put propagation tree.Such as, if the live content definition that node 209 is currently needed for transmission is high, content
Greatly, can be the father node that this node distribution bandwidth is high at backbone network A such that it is able to provide higher
Bandwidth guaranteed；Can backbone network B be the node 209 several father node of overabsorption as distribution 6,
7,8 etc..If the bandwidth that node 209 currently need not live content or live content takies is relatively
Little, node 209 can be distributed to the father node that bandwidth is less, or reduce its net of node 209
The number etc. of father node.
It is it is to be understood that although the embodiment of the present invention has two to propagate tree with backbone network A, key
Net B illustrates P2P networking as a example by having two to propagate tree, but the invention is not restricted to this.This area
Personnel are it should be appreciated that backbone network A and backbone network B can have many to propagate tree respectively.
Fig. 3 illustrates the flow chart of the networking management method of one embodiment of the invention.Such as Fig. 3 institute
Showing, the method specifically includes that
Step 300, registrar receives the status report messages of client.
In one embodiment, it is possible to use registrar be responsible for record client state, and
Distribute father node for client, safeguard whole P2P transmitting network.
In one embodiment, registrar can receive the reflection client that client timing sends
End last state status report messages, this status report messages include connection state information and/or
Discharge pattern information, discharge pattern includes flow-sensitive type and non-flow sensitive kind, connects shape
State information includes connecting without connecting, attempting or normally connecting.
In one embodiment, when client state changes, client can be to registration service
Device status report message, informs the last state of registrar client.The shape of client
State refers to the connection status of client whether flow-sensitive and client and other client.Connect shape
State is divided into again without connecting (UNCONNECT), attempting connecting (CONNECTING), normal
Connection (CONNECTED) three kinds.Registrar is receiving STATUSREPORT message
After, carry out different process according to the different conditions of client.
Step 302, registrar is according to status report messages management transfer tree, wherein, propagates
Tree is for content server as tree root, using non-flow sensitive kind client as branch point or leaves
The propagation tree set up, flow-sensitive type clients receives data by propagating tree.
In one embodiment, propagate tree composition at least two backbone network, propagate the joint in tree for many
Point has unique father node in the backbone network that it is affiliated, also has at least another one backbone network
There is father node.
In one embodiment, if many are propagated tree composition the first backbone network and the second backbone network, root
When distributing father node for client according to client traffic type information in propagating tree, if judging to obtain
Client is non-flow sensitive kind client, is client in the first backbone network and the second backbone network
End distribution father node, during for non-flow sensitive kind client distribution father node, keeps the first backbone
The number of nodes of net and the second backbone network is close；If judging, obtaining client is flow-sensitive type visitor
Family end, distributes transmission node for client in propagating tree, and flow-sensitive type clients is from propagation
Tree obtains data but not as tree interior joint.
Connection status refers to that the connection status of a client and other clients, a client have
Multiple father nodes and child node, so there being multiple connection, thus have multiple connection status.Registration clothes
Business device to arrange father node to client according to each connection status connected that client reports.?
In one embodiment, if the connection of client and father node is in without connection status, this nothing connects shape
State needs to distribute father node, is that client distributes father node according to client traffic type information.If
Client is in trial connection status, illustrates that group network system distributes father's joint for this client
Point, does not simply also have successful connection.One client can have multiple father node and child node, client
Hold with its each father node and child node will have a connection, so a client has multiple company
Connect and such as connect 1, connect 2 ... and connect n, the corresponding father node of each connection or son joint
Point.Connection status can be for concrete connection for rather than for client.As
Fruit is in without connection status (unconnected) with the connection n of father node, now to judge this father
Node is the most online, is not to judge that present node is the most online, because present node is online certainly
, otherwise can not receive its status information.
In one embodiment, if client is in normal connection status, then skill is split by band
Data are split by art, and during each inter-node communication in networking, Media Stream is divided into chronologically
The data block can distributed in an IP bag, and use integer coding data block successively.Father node
Udp protocol is used to send data block to child node.Father node can be from the Home Network father of this father node
Node and its net father node obtain the data of double redundancy, and father node first goes after receiving data block
Weight, then forwards data block and gives its child node.In the reference time delay specified, if there being number
Also confiscating according to block, child node can notify that father node resends this data block；Time delay is more than one
Specified time is then judged to packet loss, abandons retransmitting and attempts.
In one embodiment, client, when accessing this networking, can send to registrar
Add live request.If registrar receives the live request of addition of client, can basis
Client traffic type information distributes father node for client in propagating tree.
In one embodiment, when client adds live, can be by registrar hair-like
