Description
Technical field
The present invention relates to the peer-to-peer network field, relate in particular to a kind of method for informing resource node message and network entity apparatus.
Background technology
At present, (Peer to Peer, P2P) professional flow shared in network is increasing for peer-to-peer network.The problem that the P2P service traffics occupy backbone network in a large number and produce the inter-network flow has thus been brought very big challenge to the network equipment burden and the operation cost of operator.
Account under the situation of the Internet dominant position in current P2P service traffics, rudimentary backbone Internet carrier network is subjected to above-mentioned challenge and seems particularly serious.
Common bit stream in using with present P2P (Bitorrent, BT) downloading service is an example, this service technique is based on the transmission mode of the mesh network (Mesh) of index server (Tracker).As shown in Figure 1, when the user who is designated User in the ISP2 network needs the downloaded resources file, need arrive first on the BT resource issuing web site of outer net and search and obtain the resource description file, then according to the indication of resource description file by obtaining the tabulation (SeedList) of resource downloading node in (Core Router) index server in the ISP1 network of the core router between the network (Tracker), the hypothetical resource file is divided into Data1, Data2 and Data3 three parts, according to Data1, the index of Data2 and Data3 can be from downloading the affiliated resource node User1 of this document just at the same time, User2 and User3 download the resource needed file respectively.As shown in Figure 1, user User can download Data1 by the node that is designated User1 from ISP1, be designated the User2 node and download Data2 from ISP1, and the node that is designated User3 from ISP2 is downloaded Data3.
If the network that destination node that resource file is downloaded and source node do not belong to same operator, for example, the destination node (user User) that resource file is downloaded belongs to (the Internet ServiceProvider of ISP, ISP) 2 network, source node User1 and User2 then belong to the network of ISP1, and this moment, the point-to-point transmission of resource file will cause the across a network flow that produces between the different operators.
If ISP2 is rudimentary key carrier network; ISP1 is senior key carrier network; because a large amount of internet resource all concentrates in the senior key carrier network ISP1 basically; Internet resources in the rudimentary key carrier network ISP2 net are not abundant; and resource node in the resource downloading that index server provided tabulation Random assignment often; that is to say; resource node in the resource downloading tabulation that index server provided is understood plurality usually and is arranged in the backbone Internet carrier network; like this; the frequent resource of visiting in the senior key carrier network ISP1 network of user's needs that will cause rudimentary key carrier network ISP2; produce the professional inter-network flow of huge P2P thus; increased the network equipment burden of rudimentary key carrier network ISP2 greatly; increased its operation cost, and too much P2P across a network flow also can cause two communication performance bottlenecks between the carrier network.
The solution of existing reduction inter-network flow such as P2P buffer memory (P2P Cache) scheme, by transit point link (Transit Link) or the crucial convergent point of operator in Home Network some buffer memorys (Cache) node is set, these nodes use special hardware, storage and related software, and the P2P business datum content that flows through Home Network is stored.Like this, when the P2P service-user in other nets asked to visit this business datum content once more, network can utilize the business datum content of cache node storage that service is provided pellucidly with request guiding P2P cache node.Like this, flow can both be limited in transmission in the net greatly, thereby reduces the inter-network flow.
But there is following problem in said method:
P2P Cache need transit point link or crucial convergent point in Home Network be provided with P2P Cache equipment, price comparison costliness; Owing to need carry out the buffer memory of content, therefore need the more memory device of investment simultaneously, the required cost that expends is higher.

Embodiment
Below in conjunction with accompanying drawing, a kind of method for informing resource node message provided by the invention and network entity apparatus are described in detail with specific embodiment.
A kind of method for informing resource node message of providing of the embodiment of the invention for convenience of explanation, the embodiment of the invention are that example describes with two kinds of different type network ISP1 networks shown in Figure 1 and ISP2 network respectively still.
For this senior key carrier network of ISP1, same as the prior art, store the resource node information of each resource correspondence at the index server (can be more than) of ISP1 network internal, the content of this resource node information comprises the information such as IP address, port and user ID of each resource node.
As shown in Figure 2, for the ISP1 network, the method for informing resource node message that the embodiment of the invention provided specifically may further comprise the steps:
Index server in step S201, the ISP1 network receives the request of obtaining that the Home Network user side is initiated, and this request of obtaining is used to obtain the resource node information of resource requirement correspondence.
Index server in step S202, the ISP1 network is according to this resource node information acquisition request, determine the Home Network resource node information that comprises in the stored resource nodal information, and according to self service ability information of the traffic load parameter information of the subdomain net under each Home Network resource node and each Home Network resource node, further choose the required Home Network resource node information of returning, return to this user side.
This user side sends the request of connecting to each corresponding resource node respectively according to the resource node information of returning, obtain the permission of resource node after, promptly set up the transmission that mesh network carries out resource.
In above-mentioned steps S202, index server in the ISP1 network is in determining all Home Network resource node information that the stored resource nodal information comprises, further according to the traffic load parameter information of the subdomain net under each Home Network resource node, and self service ability information of each Home Network resource node, choose the Home Network resource node information that to return, select the Home Network resource node information of coming the most at last and return to user side.
In the embodiment of the invention, as shown in Figure 3, in the ISP1 network, be divided into several subdomain nets in advance, comprise subdomain net A, subdomain net B, subdomain net C and subdomain net D.The internal structure of each subdomain net as shown in Figure 4, in each subdomain net, can dispose one or more monitoring points (Detection Point, DP); For example can utilize existing DPI (Deep Packet Indentification) equipment, the effect of each monitoring point is the flow load situation of periodically monitoring in this subdomain net, add up that each node in this subdomain net is uploaded or the total amount of data download flow, the total amount of this subdomain net flow that will count then obtains the flux density value of this subdomain net divided by this subdomain net interior nodes sum.And the flux density value information that constantly current period is calculated reports the index server in the ISP1 network.
And each node in the ISP1 network in each subdomain net is also periodically added up parameters such as self CPU average service rate, internal memory average service rate and available network bandwidth and is reported index server in the ISP1 network as self service ability information.
The flux density value information of each subdomain net that the index server in the ISP1 network reports each subdomain net monitoring node, and self service ability information stores of reporting of each node and constantly being updated periodically.
When choosing the Home Network resource node, index server is according to the above-mentioned information of storage, in the Home Network resource node information of storage, the relevant information of the Home Network resource node that subdomain net flux density value is lower under selecting further, self service ability is higher returns to user side.
Why selecting according to mentioned above principle, is because in the lower subdomain net of flux density, and resource node may have higher upstream bandwidth and less load, and the resource node that service ability is high possesses the ability that other nodes more preferably provide resource.
Subdomain net flux density value information under index server is comprehensive above-mentioned, during two selection of parameter Home Networks of self service ability information resource node information, also can set above-mentioned two parameter priority, for example the service ability information priority of each resource node is in subdomain net flux density value information, under the situation of setting such priority, suppose among the figure, the flux density value of each subdomain net is arranged from small to large and is followed successively by: subdomain net A＜subdomain net B＜subdomain net C＜subdomain net D, resource node User 2 among resource node User 1 among the subdomain net A and the subdomain net B is alternative resource node, if the service ability of resource node User 2 is greater than resource node User 1, so, even the flux density value of subdomain net A is less than the flux density value of subdomain net B, index server can preferentially select the information of resource node User 2 to return to user side.
The method for informing resource node message that the embodiment of the invention provides in actual applications, if the quantity that P2P uses for resource node has requirement, for example the BT downloading service is stipulated, user side needs 4 resource nodes to carry out the download of resource (helping all parts that user side can intactly be downloaded this resource) at least, so, on the basis of above-mentioned steps, can also continue to carry out following steps:
Step S203, relatively with the quantity of the Home Network resource node that comprises in the stored resource nodal information and preset threshold.When the quantity of Home Network resource node does not reach this preset threshold, carry out following step S204.
Step S204, when the quantity of Home Network resource node does not reach preset threshold, returning outside all Home Network resource node information, also need be in the outer net resource node in the stored resource node, according to the priority orders of each default carrier network, the outer net resource node of choosing sufficient amount successively returns to user side.
The quantity of replenishing the outer net resource node information return equals quantity poor of threshold value and the Home Network resource node that has returned.
The priority orders of each carrier network, for example can be according to different autonomous territory (Autonomous System in Home Network (ISP1 network) and each outer net, AS) tree-shaped order relations and annexation between decide, the size that tree-shaped order relations between the different autonomous territory of Home Network and each outer net and annexation have determined bit transfer cost between Home Network and each outer net can preferentially select the resource node information of the outer net that transmission cost is lower with it to return to user side.
Certainly, in the embodiment of the invention, the priority orders of outer net also can be decided by other factors etc.The embodiment of the invention is not done qualification to this.
The principle and the step of the method for informing resource node message that the embodiment of the invention provides are described at this rudimentary key carrier network of ISP2 (for example network of mobile Internet operator) below.In the prior art, the ISP2 network internal does not exist can provide resource node information index server, the method for informing resource node message that the embodiment of the invention provides is provided with index server and resource publisher server in the ISP2 network, for with the ISP1 network in index server distinguish, below with the index server in first index server address ISP2 network.Can with the function setting of the resource publisher server in the ISP2 network in first index server, both be closed the same equipment that is made as in the embodiment of the invention.
Still use the BT business to carry out resource downloading with the user side User in the ISP2 network and be example, as shown in Figure 5, the method for informing resource node message that the embodiment of the invention provides, first index server need at first be finished following step:
Step S501, first index server obtain the resource description file and resolve from the resource publisher server of outer net, parse the address information of second index server that the resource description file comprised.
Obtain the resource description file of various network resources correspondence on the bigger resource publisher server of first index server download in outer net, the resource description file that receives is resolved, parse the address information of second index server that is comprised in this resource description file.
Step S502, first index server obtain the resource node information of this Internet resources correspondence according to the address information of second index server to second index server of correspondence.
For with the ISP2 network in first index server distinguish mutually, the index server that claims to be positioned at outer net is second index server.
Step S503, first index server are revised as the second index server address that comprises in the resource description file that gets access to the address of self.
Step S504, first index server are issued the resource publisher server that amended resource description file is sent in the Home Network.
In order to realize that the interior user side User of ISP2 net can directly login the resource publisher server in the Home Network, and the resource issuing web site by core router visit outer net not, in embodiments of the present invention, to name server (the Domain Name Server in the existing ISP2 network, DNS) set in advance redirection function, when user side when the name server of Home Network is initiated the logging request of login outer net resource publisher server, this name server can realize this logging request is redirected to the resource publisher server of Home Network, like this, for Home Network user side User, and do not know that the Website server of own actual log is the interior Resource Server of net.Because the redirection function of DNS belongs to the scope of prior art, does not repeat them here.
When resource publisher server in the ISP2 net receives process that Home Network user side User the initiates logging request after redirected, resource publisher server in the ISP2 net returns the content of resource publishing web page to user side User, user User selects the Internet resources that need obtain as required, just the resource publisher server to Home Network sends the request of obtaining the resource description file, after this flow process of the first index server end, as shown in Figure 6, comprising:
Step S601, Home Network resource publisher server receive the request of obtaining the resource description file that user side User sends.
The resource publisher server of step S602, Home Network returns amended resource description file to this user side.
Step S603, user side obtain this resource description file and resolve, according to the address that comprises index server in the amended resource description file, just the resource node information acquisition request is initiated to first index server in the address of first index server in the ISP2 network.
Step S604, first index server receive the request of obtaining that this user side is initiated, determine the Home Network resource node information that is comprised in the resource node information of corresponding resource of storage, and according to self service ability information of the traffic load parameter information of the subdomain net under each Home Network resource node and each Home Network resource node, from Home Network resource node information, choose the required resource node information of returning, return to this user side.
With the ISP1 network class seemingly, in the ISP2 network, can be divided into several subdomain nets in advance, each subdomain net is periodically added up the flow total amount in this subdomain net, calculates this subdomain net flux density value and reports first index server in the ISP2 network; Simultaneously, the node in each subdomain net is periodically added up parameters such as self CPU average service rate, internal memory average service rate and available network bandwidth and is reported first index server as self service ability information.
First index server in the ISP2 network is in all Home Network resource node information that the stored resource nodal information comprises, self the service ability information that reports with reference to flux density value information and each Home Network resource node of the online newspaper of the subdomain under each Home Network resource node further, choose the Home Network resource node information that to return, select the Home Network resource node information of coming the most at last and return to user side.Concrete selection principle and method also with abovementioned steps S202 in identical, be not described in detail in this.
With similar in the ISP1 network,, so, on the basis of above-mentioned steps, as shown in Figure 6, can also continue to carry out following steps if the quantity that P2P uses for resource node has requirement:
Step S605, first index server are with the quantity of the Home Network resource node that comprises in the stored resource nodal information and preset threshold relatively.
When the quantity of Home Network resource node does not reach this preset threshold, carry out following step S606.
Step S606, when the quantity of Home Network resource node of this resource correspondence of storage does not reach preset threshold, first index server is returning outside all Home Network resource node information, in the outer net resource node in the stored resource node, according to the priority orders of each default carrier network, the outer net resource node of choosing sufficient amount successively returns to user side.
The priority orders of each carrier network for example can decide according to tree-shaped order relations and the annexation between the autonomous territory of Home Network (ISP1 network) and each outer net.
The principle of specifically choosing and method are identical with step S204 among Fig. 2, are not described in detail in this.
