Description

IMPCS system and its method of delivery {ISP Managed P2P CDN Service system and providing method

The present invention relates to an Internet Service Provider Managed Peer to Peer Contents Delivery Network Service (IMPCS) system and a method of providing the same, and more particularly, to a PCSP (PSP) that does not pay a fair price through an existing anomalous PCS (P2P CDN Service). The present invention relates to a system and a method for detecting P2P CDN Service Providers and being controlled by the IMPCS system.

Traditional Content Delivery Network (CDN) services for content delivery are performed through a large number of servers installed on commercial lines. With the advent of anomalous CDN services combined with P2P technology, CDN operators have replaced the dedicated servers installed on commercial lines. There is a situation in which a general user receiving a user, that is, a user's personal computer is utilized as a content delivery infrastructure (eg, a Contents Delivery Server (CDS)). As a result, Internet service providers (ISPs) are not only able to reduce the profits of commercial lines, but they are also demanding capacity expansion due to network stability threats caused by the surge in usage of general user lines.

1 is a diagram schematically illustrating a conventional PCS service.

Referring to FIG. 1, an Internet Service Provider (ISP) 1 provides bandwidth of the Internet. In general, the ISP 1 provides a commercial line and a personal line to companies and individuals for commercial purposes, respectively, and a personal line generally provides a flat rate regardless of its usage.

On the other hand, if the line is used for commercial purposes, it is normal to use a commercial line.Dowanload Service Providers (DSPs) that provide download services such as web hard services can lease servers and lines to the IDC (Internet Data Center). Rather than providing a download service, the service is entrusted to a PCSP (P2P CDN Service Provider, 2).

The PCSP 2 provides a download service of the DSP 3 commercially using bandwidth of individual users instead of using a commercial line. For example, a specific user sends a request for downloading a predetermined content to the DSP 3. Then, the PCSP 2 connected to the DSP 3 transmits the content to the specific user in a P2P manner using a personal line from a terminal (for example, a computer, a set-top box, etc.) of individual users who store the content. I'm doing it.

When using this anomalous P2P CDN ISP (1) simply provides the Internet bandwidth, and the commercial use of a subscription-based private line is required to increase the facilities without any cost due to the increase in usage, Due to the content transmission between users using different ISPs, the traffic has been seriously damaged due to frequent traffic generation in the expensive IX (Internet eXchange) section.

2 shows a schematic configuration for implementing an IMPCS providing method according to an embodiment of the present invention.

Referring to FIG. 2, an IMPCS system 100 may be provided to implement an IMPCS providing method according to an exemplary embodiment of the present invention. The IMPCS system 100 may transmit / receive predetermined data for implementing the technical idea of the present invention through the ISP system 200 and the wired / wireless network.

In addition, the IMPCS system 100 may transmit / receive predetermined data for implementing the technical idea of the present invention with a predetermined DSP system 500 and / or a predetermined PCSP system 300.

The PCSP system 300 may be a system that is connected to the DSP system 500 through a wired or wireless network to provide a PCS to a user of the DSP system 500. At this time, according to the technical idea of the present invention, the PCSP system 300 may receive predetermined IMPCS information from the IMPCS system 100 and provide an efficient PCS by using the received IMPCS information.

In some embodiments, the IMPCS system 100 may directly provide the PCS to the DSP system 500.

The IMPCS system 100 may detect the PCSP system 300 that provides the PCS in the Internet network provided by the ISP. When the detected PCSP system 300 is not a pre-registered system, the IMPCS system 100 may transmit information about the detected PCSP system 300, that is, control information, to the ISP system 200. Then, the ISP system 200 may select any network device (eg, IS, CDS, and / or PMS, etc.) included in the PCSP system 300 such that the PCSP system 300 no longer provides the PCS. To restrict network access. Therefore, only the PCSP system 300 registered in advance in the IMPCS system 100 and paying a predetermined price can normally provide the PCS to the user.

Meanwhile, the IMPCS system 100 may generate information for efficiently providing PCS, that is, IMPCS information, for the PCSP system 300 registered in advance. The generated IMPCS information may be transmitted to the PCSP system 300, and the PCSP system 300 may perform more efficient and faster content delivery using the received IMPCS information.

The IMPCS information may include, for example, information about a recommended peer among a plurality of peers capable of performing PCS when a specific user requests downloading of specific content to the DSP system 500. That is, the IMPCS information may provide information about peers for which the terminal of the specific user will receive at least a part of the content among a plurality of peers storing the specific content. Providing the information on the recommended peer to the PCSP system 300 may include information on at least one peer to actually transmit content to a terminal of the specific user among a plurality of peers. This may refer to a case in which ranking information is transmitted after ranking peers based on a predetermined criterion.

That is, the IMPCS system 100 may select and transmit peers to participate in actual content transmission from among a plurality of peers to the PCSP system 300. Alternatively, the IMPCS system 100 may rank the plurality of peers in the order in which the contents can be efficiently transmitted to the terminal of the specific user, and transmit information on the ranked ranking to the PCSP system 300. Then, the PCSP system 300 may select peers to transmit content to the terminal of the specific user among the plurality of peers based on the received ranking information.

The technical idea for the IMPCS system 100 to detect the PCSP system 300 is a Korean patent application filed by the present applicant (Application No. 10-2011-0079665, "CDN detection system and its providing method", hereinafter 'previous application) It is disclosed in detail in '). The description and technical spirit disclosed in the specification of the previous application is included as a reference of the present specification, and may be treated as described herein.

The IMPCS system 100 may detect the PCSP system 300 using the technical idea disclosed in the previous application, but is not limited thereto. The IMPCS system 100 may detect a system that provides the PCS using an Internet network provided by an ISP. The PCSP system 300 may be detected using all the technical ideas.

In addition, the IMPCS system 100 may use network information to generate the IMPCS information. In this case, the IMPCS system 100 may use an application-layer traffic optimization (ALTO) method, that is, a protocol or an algorithm. The ALTO scheme discloses a technical idea of selecting one or more hosts (ie, peers) from a set of candidate resources (ie, peers) capable of providing content. In this case, predetermined network information (eg, network topology) may be used as a parameter. Since the ALTO method of selecting one or more hosts from the candidate set using the network information is well known, a detailed description thereof will be omitted.

In addition, according to the technical idea of the present invention, the network information may further include information on the occupancy status (for example, whether a specific IP is used) for each IP. Accordingly, the recommended peer may be extracted only to hosts (eg, peers) currently active among a plurality of peers based on the information on the occupancy status of each IP.

A detailed configuration of the IMPCS system 100 according to an embodiment of the present invention for implementing the technical idea is disclosed in FIG. 4.

4 is a diagram illustrating a schematic configuration of an IMPCS system according to an embodiment of the present invention.

4, an IMPCS system 100 according to an embodiment of the present invention includes a detection system 110, a confirmation system 120, and a management system 130. The IMPCS system 100 may further include an information generation system 140.

The IMPCS system 100 is not necessarily implemented as any one physical device, and a plurality of physical devices may be organically combined to implement the IMPCS system 100 as necessary.

The detection system 110 may detect a predetermined PCSP system 300 that performs PCS. Detecting the PCSP system 300 means detecting at least one of a predetermined contents delivery server (CDS), an index server (IS), or a peer management server (PMS) constituting the PCSP system 300. Can mean.

As such, the detection system 110 may include the PCSD 111 as disclosed in the previous application to detect the PCSP system 300. The PCSD 111 may refer to a system that detects the PCSP system 300 through the technical idea as disclosed in the previous application. Of course, the detection system 110 may detect the PCSP system 300 in a manner different from that of the PCSD 111.

According to an implementation example, the detection system 110 may receive information (eg, an IP address of a CDN server) about a specific PCSP system from a predetermined administrator terminal (not shown). Then, the detection system 110 may detect a target network device (eg, CDS, IS, and / or PMS, etc.) included in the PCSP system.

The PCSD 111 may detect at least one of CDS, IS, and / or PMS of the PCSP system 300. Since the function and operation principle of the PCSD 111 is disclosed in detail in the previous application, it will be only schematically described with reference to FIG.

3 is a view for explaining a method of detecting a PCS by the method of providing an IMPCS according to an embodiment of the present invention. Referring to FIG. 3, the PCSD 111 included in the IMPCS system 100 includes a predetermined system. The 1PCSP system 300 and / or the second PCSP system 400 may be detected.

The first PCSP system 300 may include, for example, a first CDN server 310, a first IS 320, and a first PMS 330. In addition, the first PCSP system 300 may use predetermined peers 340, 350, and 360 as the CDS.

In addition, the second PCSP system 400 may include, for example, a second CDN server 410, a second IS 420, and a PMS 430. In addition, the second PCSP system 400 may use predetermined peers 440, 450, and 460 as CDSs.

Then, the PCSD 111 included in the IMPCS system 100 may request download of predetermined content from the first CDN server 310 and collect packets received at the time of downloading. The packet analysis may be performed to generate a flow using the collected packets or to analyze packet meta information of the collected packets. Then, the CDS (eg, 340, 350, 360) participating in the download of the content may be detected based on the result of the packet analysis step.

In addition, the PCSD 111 included in the IMPCS system 100 extracts and extracts at least one packet including information on the CDS from the collected packets, based on the detected information on the CDS. The IS (eg, 320) of the PCSP system 300 may be detected based on the received at least one packet.

In addition, the PCSD 111 included in the IMPCS system 100 checks whether a predetermined probe device for collecting the packets is set as a peer used by the PCSP system 300, The PMS (eg, 330) of the PCSP system 300 may be estimated based on the packets transmitted and received by the probe device.

As described above, since the PCSD 111 detects a CDS, IS, or PMS of a specific PCSP system (eg, 300), a detailed description thereof will be omitted.

Of course, the process of the PCSD 111 detects the second PCSP system 400 is also the same as described above.

Referring back to FIG. 4, the identification system 120 may confirm whether the PCSP system detected by the detection system 110 is a system in which PCS is allowed. To this end, the identification system 120 may store information (for example, identification information such as IS, PMS, or CDN server) of the PCS allowed system in advance. If the information on the detected PCSP system (eg, 300) is not included in the previously stored information, it may be determined that the PCS is not allowed.

Then, the management system 130 may control the network use of the target network device (eg, CDS, IS, PMS) of the PCSP system when the PCSP system is a system that PCS is not allowed. To this end, the management system 130 may output predetermined control information to the ISP system 200, and the control information may include identification information of the target network device (eg, CDS, IS, PMS). have.

The ISP system 200 may then control the network usage of the target network device in a variety of ways. For example, packets output from the target network device or whose destination is the target network device may be discarded by a device such as a router, or the packet communication may not be normally performed.

Meanwhile, the CDS may not be included in the target network device whose network usage is controlled. This is because, if the CDS is a computer or a set-top box of individual users, controlling the network use of the CDS may have side effects. However, depending on the embodiment, the network usage of the CDS used for the anomalous PCS may also be controlled.

As a result, the IMPCS system 100 may prevent the PCSP system (eg, 300), which is not allowed in advance, from normally providing the PCS. For the PCSP system (eg, 400) previously allowed, the subject of the IMPCS system 100 and / or the subject of the ISP system 200 may perform predetermined charging. For example, when the subject of the IMPCS system 100 pays a predetermined price to the subject of the PCSP system (eg, 400), the cost is determined by the subject of the IMPCS system 100 and the subject of the ISP system 200. It can also be acquired by distribution.

Meanwhile, according to the technical concept of the present invention, in the case of a PCSP system (eg, 400) that is allowed in advance, the PCS can be provided more effectively and faster than just allowing the PCS.

To this end, the IMPCS system 100 may further include a predetermined information generation system 140. The information generation system 140 is based on the network information received from the ISP system 200, if the PCSP system (eg, 300) detected by the detection system 110 is a PCS allowed system, the PCSP IMPCS information of a system (eg 300) may be generated and the generated IMPCS information may be transmitted to the PCSP system (eg 300).

The network information may include, for example, network topology information of nodes located in an internet network provided by the ISP. For example, the network topology information may include information about network proximity. Using the network topology information, the information generation system 140 may generate information that enables the terminal to receive the specific content, that is, IMPCS information, from a terminal requesting specific content and peers having good network proximity transmission. have. The generated IMPCS information may be transmitted to the PCSP system (eg 300). How the information generating system 140 generates the IMPCS information is well known in the ALTO method or the ALTO protocol as described above, so the detailed description thereof will be omitted.

On the other hand, the network information may include information about the occupancy status for each IP. That is, when a specific PCSP system (eg, 300) transmits information about a plurality of peers to the information generation system 140, the information generation system 140 is currently based on the information on the occupancy status for each IP Enabled peers can generate information about recommended peers.

As such, the information generation system 140 generates and transmits information on the recommended peer to the PCSP system (eg, 300), so that the PCSP system (eg, 300) has a lack of network proximity, IX (Internet eXchange). Peers that transmit packets using the interval may not participate in content delivery. Therefore, there is an effect that the content delivery can be made in less cost and faster time.

The IMPCS information may include information about the recommended peer as described above. In order to send the information about the recommended peer to the PCSP system (eg 300), the information generation system 140 determines information about specific peers that the PCSP system (eg 300) will use as a peer, The information may be transmitted as information about the recommended peer. According to an implementation example, the information generation system 140 receives information about a plurality of peers from the PCSP system (eg, 300), and uses the received peers using predetermined criteria (eg, network proximity, etc.). Can be ranked. The ISPCS information may be transmitted by including information on the ranked ranking, and the PCSP system (eg, 300) receiving the IMPCS information may select a peer to deliver content based on the ranking information.

As such, a specific example in which effective content delivery may be performed by the IMPCS system 100 is illustrated in FIG. 5.

5 is a diagram illustrating a method of selecting a peer according to an IMPCS providing method according to an embodiment of the present invention.

It may be assumed that a network topology as shown in FIG. 5 is formed as a network for PCS. For example, as shown in FIG. 5, each network node (peer) may form a group 700, 710, 720. Although each group is also connected to each other through a network, it may be assumed that the network proximity or the communication cost is high compared to nodes belonging to the same group. In addition, it may be assumed that the network proximity between the first group 700 and the second group 710 is better than the network proximity between the first group 700 and the third group 720.

Then, when a predetermined node belonging to the first group 700 requests content download to a predetermined PCSP system 600 for PCS, the IMPCS system 100 determines whether the PCSP system 600 is allowed. You can judge. If it is determined that the system is allowed, the IMPCS system 100 receives information about a plurality of peers (eg, 701, 702, 703, 711, 712, 713, 721, 722, 723) from the PCSP system 600. Can transmit Then, the IMPCS system 100 transmits information about a recommended peer among the plurality of peers (eg, 701, 702, 703, 711, 712, 713, 721, 722, 723) to the PCSP system 600. Can be. The information on the recommended peer may be, for example, information about peer 701, peer 702, or peer 703. Then, the PCSP system 600 may transmit information on the peers 701, 702, and 703 to the node that requested the content, and the node that requested the content may then send the peers 701, 702, and 703. Can be used to receive the content. Depending on the implementation, the peers 701, 702, 703 are ranked higher, the peers 711, 712, 713 are ranked higher, and then the peers 721, 722, 723 are ranked higher. Information indicating that the rank is high may be included in the IMPCS information in a predetermined form and transmitted to the PCSP system 600. Then, the PCSP system 600 may select several high ranking peers and transmit information about the selected peers to the node that requested the content.

Accordingly, the PCSP system 600 can deliver content more quickly and effectively, and can prevent excessive expansion of equipment by selecting peers that have less network communication costs from an ISP perspective, and the PCSP system 600. There is also an effect that a predetermined profit can be obtained in exchange for using a content delivery service commercially using this private line. The ISP further includes various parameters (for example, information on a section with high network traffic) in the network information transmitted to the IMPCS system 100, and the IMPCS system 100 efficiently recommends peers using these parameters. Of course, effective content delivery can be performed while reducing network load.

The IMPCS providing method according to an embodiment of the present invention can be embodied as computer readable codes on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, hard disk, floppy disk, optical data storage, and the like, and also in the form of carrier waves (e.g., transmission over the Internet). It also includes implementations. In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. And functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers skilled in the art to which the present invention pertains.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
