Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a network content management method and a block chain content network platform.
Background
Video and voice communication traffic on the internet is increasing day by day, and a data transmission bottleneck existing in a Transmission Control Protocol (TCP)/internet protocol address (IP) system structure will be further highlighted undoubtedly by the high definition video on demand service. Peer-to-Peer (P2P) systems such as Bit Torrent are widely used for multimedia data transmission, but their transmission efficiency is not ideal, because the Peer can only obtain data blocks from a small part of the Peer, and in general, has only limited information when the Peer downloads the same content and network topology. An information-centric networking (ICN) has been developed in this context, which changes the current end-to-end communication mechanism of the internet, strips content from the location of a terminal, and provides services such as storage and multiparty communication through a publish/subscribe paradigm. The ICN proposes to change the point of interest of the user from the terminal to the content, i.e. the user does not care where to obtain the data he wants, but only what the wanted content is.
Content-centric Networking (CCN) is a specific implementation of the most studied ICN. There are two main types of packets in the CCN: a content request packet (interest packet) and a content data packet (data packet). In CCN, content is determined by the identification of the content, similar to an IP address prefix, for example: "/aaa.cn/video/wigeta.mpg", wherein aaa.cn is the full-web recognizable name, video is the content type, and wigeta.mpg is the content name. The request packet is used to transmit a request for content, and the node receiving the request transmits response data through the content packet if the request can be satisfied. The IO of the CCN adopts hierarchical naming, the global routing system at least needs to process IO name prefix at the content provider level, and the forwarding state of each packet guides the data packet to the user along the transmission path. The number of name prefixes of the CCN will also reach the level of size of the secondary domain name.
The CCN network mainly uses a content-centric request response mechanism and a caching technology, and does not have a content pull technology, so that users who access content in the first batch may suffer from a high delay, and cannot perform content pre-caching according to business needs and usage scenarios, thereby reducing the experience of the users.

CCN is the most relevant ICN solution in existence. The basic communication mode of the CCN is centered around named content, user requests named content, content publishers (servers) publish and transmit named content, CCN routers cache and transmit named content.
The CCN network mainly uses a content-centric request response mechanism and a caching technology, and does not have a content pull technology, so that users who access content in the first batch may suffer from a high delay, and cannot perform content pre-caching according to business needs and usage scenarios, thereby reducing the experience of the users.
Based on the foregoing technical background and technical problem, referring to fig. 1, an embodiment of the present invention provides an architecture diagram of a blockchain content network platform, where the blockchain content network platform includes a parent chain, a child chain, and a blockchain SDK plug-in; the parent chain comprises parent chain peer nodes and child chain registration nodes on all child chains; the sub-chain comprises a sub-chain registration node and a sub-chain cluster consisting of at least one sub-chain peer node; and the block chain SDK plug-in unit communicates with the sub-chain peer node corresponding to the block chain SDK plug-in unit.

The sub-chain peer node, the sub-chain registration node and the parent-chain peer node all participate in consensus computation and data reading and intelligent contract execution: and operating an intelligent contract to synchronize the account book, calculating content cache information summary information through the intelligent contract, and then uploading the content cache information summary information to a parent chain peer node through a child chain registration node. In addition, 1 subchain registration node and M subchain Peer nodes form a subchain (M is variable and the number of Peer nodes on each subchain is not necessarily the same according to flexible division of areas, manufacturers, network domains and the like), each subchain is connected with a parent chain through a subchain registration node, and all the subchain registration nodes and the parent chain Peer nodes form the parent chain. In the blockchain content network platform, the sub-chain peer node and the sub-chain registration node, and the sub-chain registration node and the parent chain peer node are communicated through a set intelligent contract.
Referring to fig. 2, an embodiment of the present invention provides a network content management method, which is applied to a blockchain content network platform, where the blockchain content network platform includes a parent chain peer node, a child chain registration node, and a blockchain SDK plug-in, and the method includes:
201. a block chain content network platform receives a service strategy sent by an operator through a parent chain peer node; the service strategy comprises caching an appointed content data packet and strategy duration in an appointed sub-chain peer node; the service strategy carries the identifier of the sub-chain peer node.
202. And the block chain content network platform sends the service strategy to the sub-chain peer node through the parent chain peer node according to the identifier of the sub-chain peer node.
Wherein, step 202 specifically includes:
the method specifically comprises the following steps:
2021. and the block chain content network platform positions the sub-chain registration node through the parent chain peer node according to the identifier of the sub-chain peer node.
2022. And the block chain content network platform sends the service strategy to the sub-chain registration node through the parent chain peer node according to the position of the sub-chain registration node.
2023. And the block chain content network platform sends the service strategy to the sub-chain peer node through the sub-chain registration node according to the identifier of the sub-chain peer node.
203. And the block chain content network platform determines that the content data packet is not cached in the first router through the sub-chain peer node according to the service strategy, and then sends the service strategy to the block chain SDK plug-in.
In one implementation, step 203 is followed by:
s11, the blockchain content network platform determines that the interest source table PIT does not contain the source information of the content data packet through the blockchain SDK plug-in.
S12, the block chain content network platform determines that the forwarding information base FIB (forward information base) contains the forwarding information of the content data packet through the block chain SDK plug-in, and then obtains the content data packet according to the forwarding information of the content data packet.
In one implementation, step 203 is followed by:
s21, the blockchain content network platform determines that the interest source table PIT does not contain the source information of the content data packet through the blockchain SDK plug-in.
S22, the block chain content network platform determines that the forwarding information base FIB does not contain the forwarding information of the content data packet through the block chain SDK plug-in.
The FIB is mainly used to record forwarding information of content request packets and forwarding information of prefixes of different content names. If a port (forwarding information) of the receiving apparatus with respect to the content packet is recorded in the FIB, the content packet is acquired from the receiving apparatus according to the port of the receiving apparatus.

204. And the block chain content network platform determines that the interest source table PIT contains the source information of the content data packet through the block chain SDK plug-in, and acquires the content data packet according to the source information of the content data packet.
It should be noted that the PIT is mainly used for a source port that records various content request packets, so that the corresponding content is forwarded back according to the port after being received, and if the corresponding content has been requested, a requested source port and the requested content are recorded. That is, if the PIT records the source port of the content request packet that needs to be obtained, the content request packet is obtained from the device corresponding to the source port according to the source port of the content request packet.
205. And the block chain content network platform sends the content data packet to the first router through the block chain SDK plug-in, monitors the first router to cache the content data packet, and does not delete the content data packet within the strategy duration.
Optionally, the content request packet and the content data packet corresponding to the content request packet may be generated with respective corresponding service IDs; carrying the service ID in the process of forwarding the content request message; and comparing the service ID after receiving the content data packet to confirm whether the content data packet is the content data packet correspondingly acquired by the content request message. The service ID of the content request packet and the service ID of the content data packet may be the same or different, and when different, the service IDs of the two may be set correspondingly; for example, the service ID of the content request packet and the service ID of the content data packet may be set to 1. In addition, the block chain content network platform may further include, after or before sending the content request messages to other routers in sequence according to a preset sequence through the block chain SDK plug-in: recording the content request message in the PIT; and recording a preset special value (such as U) of a port of the content request message entering the first router in the PIT.
For better understanding, referring to fig. 3, steps 203, S11, S12, S21, S22, S23 and S24 are exemplarily illustrated, and specific steps are as follows:
301. and the block chain content network platform determines that the content data packet is not cached in the first router through the sub-chain peer node according to the service strategy, and then sends the service strategy to the block chain SDK plug-in. It jumps to step 302.
302. And the block chain content network platform generates a content request message and a service ID of the content request message according to the service strategy through the block chain SDK plug-in.
303. And if the block chain content network platform determines that the PIT contains the source information of the content data packet through the block chain SDK plug-in. It jumps to step 308, otherwise it jumps to step 304.
304. And if the block chain content network platform determines that the FIB contains the forwarding information of the content data packet through the block chain SDK plug-in. It jumps to step 310, otherwise it jumps to step 305.
305. And the block chain content network platform sequentially sends the content request messages to other routers according to a preset sequence through the block chain SDK plug-in. It jumps to step 306.
306. And the block chain content network platform records the content request message in the PIT through the block chain SDK plug-in. It jumps to step 307.
307. The block chain content network platform records a port of a content request message entering the first router as a preset special value U in the PIT through the block chain SDK plug-in. And (6) ending.
308. The block chain content network platform records a port of a content request message entering the first router as a preset special value U in the PIT through the block chain SDK plug-in. It jumps to step 309.
309. And discarding the content request message. And (6) ending.
310. And selecting multi-interface forwarding according to the FIB. And (6) ending.
It should be noted that step 302 may be added at any step after the blockchain content network platform receives the service policy through the blockchain SDK plug-in. In addition, fig. 3 is only briefly described, and the specific flow mainly includes text description.
In addition, when the first router caches the content data packet, the method may include the following steps: step1) the router receives the content data packet message; step2) the router checks whether the service ID in the content data packet message matches with the service ID in the content request message; if the data message is matched with the normal data message, jumping to step3, otherwise, processing according to the processing flow of the normal data message; step3) to check whether the port of the matched content request message entering the first router in the PIT is a preset special value U; if yes, jumping to step4, otherwise, processing according to the processing flow of the normal data message; step4) to see if there is a content packet in the first router's cache; if yes, discarding the received content data packet; if not, the content data packet is cached and then the received content data packet is discarded.
In one implementation mode, the block link point configuration mainly includes that all routers in the CCN are used as alliance links on Peer nodes of sub-chains, the sub-chain configuration can be divided according to regions (or other rules), each M Peer nodes form one sub-chain, one Peer node is selected from the sub-chains to serve as a sub-chain registration node, and the sub-chain registration node is responsible for carrying out account book synchronization with a parent chain; the initialization process of the block chain content network platform comprises the following steps: step1) the parent chain peer node forms a federation chain digital certificate and sends the federation chain digital certificate to each router node; step2) each node receives the certificate and then installs the certificate, and starts the block chain peer node of the node; step3) after detecting that the corresponding peer node (including the sub-chain and the mother chain) is started, the management node performs configuration operation of the service and the intelligent contract; step4) all steps are completed and initialization is completed.
In one implementation manner, the account book synchronization process of the parent chain peer node, the child chain peer node, and the child chain registration node includes the following steps: step1) the sub-chain Peer node calculates the cache data to form the summary information of the content name data; step2), triggering intelligent contracts alpha inside all the sub-chains, and sharing the cached summary information and other information (Peer addresses, PeerIDs and the like) inside all the sub-chain Peer nodes inside the sub-chains as accounts inside the sub-chains through the intelligent contracts until the accounts are completely updated; after receiving the account book information, each sub-chain Peer node verifies the validity of the account book information and performs data synchronization after the account book information passes the validity; step3), triggering an intelligent contract beta in a parent chain, summarizing account book information and other information (child chain addresses, child chain IDs and the like) in the child chain by a child chain registration node, broadcasting the information in the parent chain through the intelligent contract beta, and verifying and storing the account book information of other child chain registration nodes; after receiving the account book information, the parent chain peer node and each child chain registration node firstly carry out validity verification and then carry out data synchronization after the account book information passes the validity verification; step4) the child chain registration node and the parent chain Peer node store all child chain account book information, but the account book does not distinguish Peer nodes, but only distinguishes the child chain; step5) repeating the above steps after every S time interval, and updating the account book content.
