Detailed Description
For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the invention discloses a method and a system for realizing open source community access in a multi-mode network, which can realize multi-mode network access on the basis of the original open source community by researching cross-mode data transmission logic of two mode subnets in a cross-mode manner and utilizing the interaction between a gateway of each mode subnet and the open source community. Therefore, users of different modal networks can access the same open source community, and the user quantity of the open source community is increased; and resources consumed by building the same open source community in different modal networks can be reduced, meanwhile, personnel for maintaining websites are reduced, and content synchronism is kept.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for implementing open source community access in a multi-modal network according to an embodiment of the present invention. The method for realizing the access of the open source community in the multi-modal network can be applied to an access system of the open source community, or can be expanded to an access system or an access module of the multi-modal network of other APP terminals, and the application of the method is not limited in the embodiment of the invention. As shown in FIG. 1, the method for realizing open source community access in the multi-modal network can comprise the following operations:
101. and obtaining an interest packet of the open source community built in the first mode subnet or the second mode subnet, wherein the interest packet at least comprises a mode address of the mode subnet where the open source community content server is located.
Since in the multi-modal network, a case that two modal subnets access each other is often involved, for example, the open source community is set in one of the modal subnets, and other modal subnets to be accessed are all set in the other modal subnet, so that a problem of cross-mode access exists, and of course, a case that other third modal subnets access the open source community together is also included, according to the main concept of the present invention, an access manner of the third modal subnet may be equal to an access manner of another modal subnet not in the open source community, so in this embodiment, cross-mode access is mainly performed in two modes, namely, the first modal subnet and the second modal subnet.
The method comprises the steps of firstly obtaining an interest packet of an open source community, wherein the open source community is built in a first modal subnet or a second modal subnet, and the mode of obtaining the interest packet can be provided for contents recorded by a server of the open source community through a terminal of the open source community, wherein the interest packet can comprise a network position of a content server of the open source community, a modal address of the modal subnet where the content server of the open source community is located, such as an IP address or an NDN address, and information which can be used for determining the position where the open source community is located and the contents, such as a modal address, a content name and the like of an edge gateway router of the modal subnet where the content server of the open source community is located.
102. And sending the interest packet of the open source community to an edge gateway router of the subnet in the first mode or an edge gateway router of the subnet in the second mode according to a preset access thread rule.
And then, sending the interest packet to an edge gateway router of the modal subnet according to a preset access thread rule, and if the current position of the open source community is in the second modal subnet, processing the interest packet of the open source community according to the access thread rule and then sending the interest packet to the edge gateway router of the first modal subnet. It should be noted that, although the open source community, i.e., the server itself, is in the subnet of the second modality, the terminal according to the open source community can directly transmit on the subnet side of the first modality and process according to the access thread rule. The processing of the access thread rule is a rule obtained by the inventor according to experience accumulation of the mode subnet and the gateway, and can be specifically referred to the following content.
Similarly, if the current position of the open source community is in the subnet in the first mode, the interest packet of the open source community is processed according to the access thread rule and then is sent to the edge gateway router of the subnet in the second mode.
103. And the edge gateway router of the subnet with the first mode or the edge gateway router of the subnet with the second mode processes the interest packet to generate an access packet.
Then, the edge gateway router of the first-mode subnet or the edge gateway router of the second-mode subnet processes the interest packet, the processing mode is a key component of cross-mode access, after the interest packet is analyzed, the content in the interest packet is firstly matched with the field of the current-mode subnet (i.e. the modal subnet where the server of the open-source community is located) and the like, so that the interest packet of the open-source community can be 'understood' by the current-mode subnet, then the understood data packet is sent to interact with the modal subnet where the open source community is to be accessed, processing according to this modality of subnets may include direct communication "learning" with the servers of the open source community, which, thereafter, the "learned" data packet is then returned as an access packet to the subnet of the current modality, and for a specific implementation of this step, please refer to the following example.
104. And routing the access packet to the user side of the first-mode subnet through the edge gateway router of the second-mode subnet or routing the access packet to the user side of the second-mode subnet through the edge gateway router of the first-mode subnet so as to realize access to the open source community in the multi-mode network.
After the access packet is transmitted back to the current modal subnet, the access packet can be directly routed to the user side by the edge gateway router of the current modal subnet for simple decompression, protocol operation and other operations, and the user side can directly use the access packet to access the server of the open source community in another modal subnet, so that the access efficiency and the resource utilization rate are greatly improved, the problem that the existing server carrying is limited by multi-modal access is solved, and the layout planning of multi-modal network construction is not facilitated.
It should be noted that the open source community in this embodiment is only an example object in an application layer, and the present invention is not limited to access to the open source community by the multimodal network, and all the access to other terminals, communities, websites, etc. having servers belong to the protection scope of this embodiment.
Specifically, to explain the implementation of the present embodiment in more detail, as shown in fig. 2 and fig. 3, the overall steps are described by taking the first-modality network as an NDN network and the second-modality network as an IP network as an example.
Illustratively, as shown in FIG. 2, when a server of an open source community is hosted on a second-modality subnet, IP, subnet, a logical block diagram of the content of the open source community that a user of a first-modality subnet, NDN, subnet, wants to access.
In the implementation of this embodiment, as a premise that the steps of this embodiment are supported, the terminal of the open source community records information such as a network location and an IP address of the open source community content server, and an IP address and a content name of an edge gateway router of an IP subnetwork where the open source community content server is located; the open source community terminal can package a data packet supported by the network according to the network where the user is located; the edge gateway router of the NDN sub-network simultaneously runs the NDN protocol and the IP protocol and has an IP address.
Firstly, generating and sending an interest package about an open source community by a terminal APP of the open source community, wherein the content name in the interest package is named in a mode of 'open source community + IP', as shown in fig. 2 (r); then, the interest packet is subjected to content detection in the first-modality subnet NDN subnet, which may also be referred to as content matching, and when the content of the first-modality subnet, i.e., the content name, is detected to have a second-modality subnet field, i.e., an IP field, during the detection or matching process, the interest packet is forwarded to an edge gateway router of the first-modality subnet NDN subnet, as shown in fig. 2. Therefore, the conversion processing of the interest package in the first stage can be completed, and the interest package is processed into the interest package in the first modality which can be understood by the subnet in the first modality.
Then, after receiving the Interest packet, the edge gateway router of the first-mode subnet NDN subnet parses the Interest packet to obtain the second-mode address IP address of the content server of the open-source community, and generates a translation table, for example, the translation table is recorded in a { Interest' name, router X IP } format, and then the IP address of the edge gateway router of the first-mode subnet NDN subnet is used as a temporary source address, and is encapsulated into a UDP data packet and forwarded to the edge gateway router of the second-mode subnet IP subnet where the open-source community content server is located, as shown in fig. 2 by (c). Thus, the process of packaging and sending the first-modality interest package to the second-modality subnet is completed.
Then, after the encapsulated UDP data packet reaches the second-mode subnet IP subnet where the content server of the open source community is located, performing routing addressing with an IP address in the second-mode subnet IP subnet to find the content server of the open source community, and obtaining the content of the open source community from the content server, as shown in fig. 2; the content server of the open source community encapsulates the content of the content server into an access packet, which may also be understood as a UDP data packet, and then, the IP address of the edge gateway router of the first-mode subnet NDN subnet is used as a temporary destination address, and the access packet not belonging to the IP subnet is sent out, and the access packet not belonging to the IP subnet may be understood as a protocol access packet not belonging to the IP subnet, as shown in (c) of fig. 2. Therefore, the process of packaging the cross-modal content needing to be accessed in the open source community of the second-modal subnet into the access package which can be understood by the first-modal subnet is completed.
Finally, the edge gateway router of the second-mode subnet forwards the access packet to the edge gateway router of the first-mode subnet NDN according to a conversion table { Interest' name, router X IP }, as shown in (ninu) of fig. 2, after receiving the access packet, the edge gateway router of the NDN subnet analyzes the access packet according to a mode of analyzing a UDP data packet, and encapsulates the access packet into a format of a data packet of the first-mode NDN, as shown in (ninu) of fig. 2; the encapsulated NDN packet can be routed in the first-modality NDN subnet in the protocol of the first-modality NDN subnet and forwarded to the user side, as shown in the portion in the interior of the capacitor in fig. 2. Therefore, the whole closed-loop logic thread of cross-modal access is completely realized, a user side of the NDN network directly accesses a server of an open source community of the IP network without crossing the modalities and crossing the server, the isolation of two modality networks is broken, and the establishment of a multi-modal network is facilitated.
Illustratively, as shown in FIG. 3, when a server of an open source community is built on a first-modality subnet, NDN, subnet, a user of a second-modality subnet, IP, subnet, wants to access the contents of the open source community.
In the implementation of this embodiment, as a premise that the steps of this embodiment are supported, the terminal of the open source community records information such as a network location and an IP address of the open source community content server, and an IP address and a content name of an edge gateway router of an IP subnetwork where the open source community content server is located; the open source community terminal can package a data packet supported by the network according to the network where the user is located; the edge gateway router of the NDN sub-network simultaneously runs the NDN protocol and the IP protocol and has an IP address.
Firstly, generating an interest packet of an open source community by an open source community terminal APP on a client, and encapsulating the interest packet into a UDP (user Datagram protocol) data packet, wherein an IP address of an edge gateway router of a first-mode subnet NDN (named data network) subnet is used as a temporary destination address, and the encapsulated UDP data packet is routed and addressed in the IP subnet, as shown in a second part in FIG. 3; then, the UDP packet that does not belong to the IP subnet of the second modality is sent to the edge gateway router of the IP subnet of the second modality, and further sent to the edge gateway router of the NDN subnet of the first modality, as shown in the fourth modality in fig. 3. Thus, the conversion processing of the interest package in the first stage is completed, and the interest package is processed into the second-modality interest package which can be understood by the second-modality subnet.
Then, after receiving the UDP data packet, the edge gateway router of the first-mode NDN subnetwork analyzes the UDP data packet and encapsulates the UDP data packet into a first-mode NDN Interest packet, and generates a translation table { Interest' name, user IP }, as shown in the fourth in fig. 3; then, running a first-mode NDN protocol to route in the first-mode NDN subnet and match the content of the first-mode interest packet, thereby finding the content of the open-source community, specifically, when detecting that the content includes a first-mode subnet field, forwarding the interest packet to an edge gateway router of the first-mode subnet to obtain the content of the open-source community, as shown in fig. 3 by a fifth step; then, the content server of the open source community encapsulates the content of the open source community into a first-mode NDN data packet, i.e. an access packet, and routes the matched user in the first-mode NDN subnet, as shown in fig. 3 by sixthly; then, operating the first-mode NDN protocol to match users in the first-mode NDN subnetwork, and forwarding a first-mode NDN data packet, that is, an access packet, which does not belong to a request of a user of the first-mode NDN subnetwork, to the first-mode NDN subnetwork edge gateway router, as shown in fig. 3; after receiving an access packet returned by an Interest packet which does not belong to a user request of the NDN subnetwork of the first mode, the edge gateway router a of the NDN subnetwork of the first mode encapsulates the access packet according to a generated translation table { Interest' name, user IP } and sends the access packet to an edge gateway router of a subnetwork of the second mode, as shown by (+) in fig. 3. Thus, the process of cross-modal packaging of the content needing to be accessed in the open source community of the first-modality subnet into an access package understandable by the second-modality subnet is completed.
Finally, the edge gateway router of the second-mode subnet IP subnet parses and encapsulates the access packet into a second-mode IP data packet, and routes and addresses in the IP subnet and sends the second-mode IP data packet to the user side in the second-mode subnet IP subnet via the second-mode IP protocol, as shown in the third part in fig. 3. Therefore, the whole closed-loop logic thread of cross-modal access is completely realized, the user side of the IP network directly accesses the server of the open source community of the NDN network without cross-modal and cross-server, the isolation of two modal networks is broken, and the establishment of a multi-modal network is facilitated.
