Embodiment
The embodiment of the invention provides a kind of resource downloading control method and device, in order to raising resource downloading speed, and control DHT network node access profile, improve the efficient that resource transmission connects.
The embodiment of the invention, based on the resource downloading of DHT network (the pure DHT network that does not have any server), (BitTorrent, BT) host-host protocol carries out the resource-sharing transmission according to bit stream.The resource of downloading with the BT host-host protocol is the BT downloaded resources, and the resource of mentioning in the embodiment of the invention is the BT downloaded resources.The client of downloaded resources is the BT client.
The embodiment of the invention is through obtaining the network message of said DHT network and BT-Tracker network (BT-Tracker network be do not have the network of DHT function or close the network of DHT function or successfully be not connected to the network of DHT) at preset node; From this message, obtain the network node information in said DHT network and the BT-Tracker network, store this network node information in advance.When the client resource download request that gets access at said preset node from the DHT network; From the network node information of said storage in advance, obtain the client ip address of sharing same resource according to this resource downloading request; This IP address is returned to the client (peer) of asking downloaded resources, so that this client is through said IP address and other client shared resources.
Since the IP address of the network node of the shared same resource that the client of request downloaded resources obtains both from the BT-Tracker network node also from the DHT network node; And the client at this place, IP address is client in the net; With respect to carrying out resource downloading at pure DHT network, not only increased the quantity of sharing the client of same resource, also limited the outgoing access of the node of request downloaded resources; Accelerate resource downloading speed, improved the transmission joint efficiency of resource-sharing.
The embodiment of the invention; Through obtaining DHT network and BT-Tracker network of network message simultaneously; No matter whether the DHT network is connected with the BT-Tracker network; Resource downloading requesting client in the DHT network (resource query node) can find the node of the same resource of BT-Tracker shared in network, with the nodes sharing resource in this BT-Tracker network.The prior art of comparing has increased the client terminal quantity of retrievable shared resource, accelerates resource downloading speed with this.
Said BT-Tracker network and DHT network are two kinds of different resources shared networks.In P2P resource-sharing application, DHT NetFind resource process is different with the mode of BT-Tracker NetFind resource process.Below with brief account once DHT network and BT-Tracker network.
The DHT network is a kind of network of resource distribution formula storage; Do not need central server; Each network node is responsible for storing the sub-fraction route; In the DHT network, seek the IP address of other network nodes of downloading same resource through the node lookup method, thereby realize the addressing and the storage of whole DHT network.Through carrying out the download of resource and share in the IP address that searches out.The network node that sends the shared same resource that the node of resource downloading request searches out is many more, and resource downloading speed is just fast more.Each node (NODE) on the DHT network all has the address ID of unique 20 bytes.Result through to the XOR of certain two node ID weighs two logical reach between the node.DHT node for starting first through manual appointment or the embedded mode of software, obtains first super node of this node, and this super node can be the adjacent node or the nonneighbor node of the said DHT node that starts first.Destination node ID is the resource characteristic value info_hash of resource to be downloaded.Internodal communication mode is the KRPC message based on UDP, and through the instruction of test instruction (PING), querying node (FIND_NODE), resource downloading request instruction (GET_PEERS), and searching and share resource accomplished in statement instruction (ANNOUNCE).Whether the ping testing node is online and normally provide and reply; FIND_NODE request is searched more the nodal information near destination node to adjacent node; The GET_PEERS request is to the nodal information of the shared same resource of destination node inquiry, and the node of request downloaded resources obtains resource-sharing person's node address through this destination node.Resource information (shared resource characteristic value) and this IP addresses of nodes that ANNOUNCE message has to this node of adjacent node statement.Each node has all been safeguarded a Hash table, so all be kept in this Hash table about the information of node.When receiving the request of client node resource downloading, serve as according to inquiry shared resource information with local Hash table, and return Query Result.
Tracker server in the BT-Tracker network is the IP address of buffer memory about all holders of seed file and download person; Be equal to a database fully; Holder that seed file is all and download person submit the IP address of oneself to same Tracker; Tracker collects these IP addresses, and returns these IP addresses according to the resource downloading request of client, and the shared procedure of follow-up resource and Tracker are irrelevant.The IP address of each client or other relevant informations all are kept in the Tracker server.
To specify the technical scheme that the embodiment of the invention provides through accompanying drawing below.
Referring to Fig. 1, a kind of resource downloading control method that the embodiment of the invention provides may further comprise the steps:
S101, obtain the client resource download request, therefrom confirm the address of characteristic value with this client of the resource that client-requested is downloaded;
Wherein, said client resource download request is from predeterminated position, obtains like the carrier network aggregation node, and the type of the network message that the different preset position obtains is different.For example: the network message that Netcom carrier network aggregation node place obtains is all from the network message of Netcom's client, and the network message that telecom operators networks converge node place obtains is all from the network message of telecom client end.The present invention is through obtaining the DHT network message from client at some carrier network aggregation nodes; Reduce the inter-network resource-sharing; Can improve resource-sharing transmission joint efficiency, accelerate DHT Internet resources speed of download, avoid the economic loss that causes because of the inter-network shared resource.
Consolidated network operator runs polytype network, and for example: resource sharing network comprises DHT network and BT-Tracker network at least.The said client resource download request of obtaining, what specifically obtain is the resource downloading request of DHT networking client.Can certainly obtain the resource downloading request of BT-Tracker networking client.
Obtain the resource downloading request of DHT networking client; Be specially; Monitor the network message of a certain carrier network aggregation node through the DHT network transmission protocol; Resolve through the network message that listens to being carried out deep message, extract the resource downloading solicited message that client in the DHT network message (query node) is sent.
Said client resource download request is specially the GET_PEERS instruction message, and GET-PEERS message is used for the information to destination node inquiry peer, like the client of the same resource of searching download, and the IP address of this client.
Need to prove; Obtain the resource downloading request of BT-Tracker networking client; Can monitor the network message of said carrier network aggregation node through the BT-Tracker network transmission protocol; Resolve through the network message that listens to being carried out deep message, obtain the request of BT-Tracker networking client resource downloading.
The characteristic value that whether comprises the resource of said client-requested download in the nodal information tabulation that S102, judgement are provided with in advance; Wherein, Comprise distributed hashtable DHT network and bit stream-central server BT-Tracker network of network address of node in the tabulation of said nodal information, the corresponding relation of the characteristic value of the resource that can provide with this network node;
The information that said nodal information tabulation is preserved generates in advance, and referring to Fig. 2, this nodal information tabulation is specifically obtained by following steps:
S201, from said predeterminated position, obtain the address of network node, and the characteristic value of this network node resource that can provide;
Preferably, the address of said network node, and the characteristic value of this network node resource that can provide is from DHT network message and BT-Tracker network message.
Particularly; Pass through the HTTP host-host protocol of DHT host-host protocol and Tracker server respectively; Network message to predeterminated position (like the carrier network aggregation node) carries out the deep message parsing; The network message that parsing is obtained is divided into two types: DHT network message and BT-Tracker network message, obtain the information declaration message in the message.For example, obtain the ANNOUNCE message in the DHT network message, and obtain the ANNOUNCE message in the BT-Tracker network message.The IP address, the shared resource characteristic value that have comprised network node in the ANNOUNCE message.Extract the network node address in the ANNOUNCE message, and the resource characteristic value of resource that this network node has.Said ANNOUNCE message shows the resource of this nodes sharing from network node in the net.Wherein, communicate through KRPC message between node based on UDP.
S202, the corresponding relation of said node address and said resource characteristic value is stored in the said nodal information tabulation.This nodal information tabulation also is the concordance list of local maintenance.
The predeterminated position that obtains ANNOUNCE message is a same position with the predeterminated position that obtains said client downloads request, is the carrier network aggregation node.
S103, when comprising the characteristic value of the resource that said client-requested downloads in the tabulation of said nodal information, confirm the address of the pairing network node of characteristic value of the resource that this client-requested is downloaded in the said nodal information tabulation; Otherwise what is not done.
S104, according to the address of said client, the address of said definite network node is sent to said client.So that said client according to said node address, realizes the resource downloading of said client.
Preferably,, the address of said definite network node is sent to said client, particularly,, the address of said definite network node tried to be the first reply to said client according to the address of said client according to the address of said client.
The general sense of said " try to be the first and reply " is: through intercepting and capturing request message (like intercepting client resource download request among the present invention); And based on the communication protocol of request message; Simulate legal response message; Before real response message arrives destination, send to the response message of simulation the process of destination.
The embodiment of the invention, realize trying to be the first replying through following steps:
