Description

Multi-mode network topology structure
Technical Field
The application relates to the technical field of computer networks, in particular to a multi-mode network topology structure.
Background
Existing internet infrastructure mainly employs single address identification and addressing routing technology based on IP addresses. Correspondingly, the IP network topology consisting of backbone network (including backbone network router) and lan can only support communication between lan and wan based on IP address. But in reality, the user content can be addressed and routed with the file name (rather than the IP address) as an identification, thereby improving network transmission efficiency; similarly, the network may also use the identity ID of the user, the terminal, or the network node as an identifier for addressing and routing; and mapping the geographic position coordinates of the user, the terminal or the network node to a geographic position identifier for addressing and routing. Communication networks formed based on different identities, also referred to as different network modalities.
The existing different modal networks all exist independently and are not effectively fused; the corresponding various network topology technical schemes can not simultaneously support IP address identification, content identification, identity identification and geographic position identification on the basis of the same network topology architecture, and provide local area network communication and wide area network communication functions in single mode and mixed mode.
Disclosure of Invention
An object of the embodiments of the present application is to provide a multi-modal network topology structure, so as to solve the problem that the related art cannot support an IP address identifier, a content identifier, an identity identifier, and a geographic location identifier at the same time, and provide single-modal and mixed-modal local area network communication and wide area network communication.
According to an embodiment of the application, a multi-modal network topology is provided, comprising a backbone network part (KN) and a plurality of different types of network identity control domains, the backbone network part (KN) comprising a plurality of interconnected backbone level multi-modal routing devices (KR), the plurality of different types of network identity control domains being interconnected by the backbone network multi-modal routing devices (KR).
Further, the backbone level multi-modal routing device (KR) may simultaneously support routing of IP address identification, geo-location identification, identity identification, content identification network packets.
Furthermore, each network identification control domain is provided with an intra-domain multi-mode routing switching Device (DR) which simultaneously supports IP address identification, geographic position identification, identity identification and content identification, a server and user terminal equipment.
Further, the number of the plurality of different types of network identification control domains is 10.
Further, the plurality of different types of network identification control domains are composed of two IP address identification control domains (CD 1, CD 2), two geographical location identification control domains (CD 3, CD 4), two identity identification control domains (CD 5, CD 6), two content identification control domains (CD 7, CD 8) and two hybrid identification control domains (CD 9, CD 10).
Further, the mixed identification control domain (CD 9, CD 10) comprises an IP address identification, a geographic position identification, an identity identification and a content identification.
The technical scheme provided by the embodiment of the application can have the following beneficial effects:
according to the embodiments, the communication capability in the local area network environment (i.e. within the network identification control domain) of single mode and/or multi-mode mixture and/or the wide area network environment communication capability across the backbone network can be provided with lower construction cost by arranging the backbone network part (KN) and a plurality of different types of network identification control domains. The backbone level multi-mode routing equipment (KR) and the intra-domain multi-mode routing switching equipment (DR) can simultaneously support the routing of IP address identification, geographic position identification, identity identification and content identification network data packets. Therefore, the problems that IP address identification, content identification, identity identification and geographic position identification cannot be simultaneously supported, and single-mode and mixed-mode local area network communication and wide area network communication are provided in the related technology are solved.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
FIG. 1 is a schematic diagram illustrating one implementation of a multi-modal network topology, according to an example embodiment. As shown in fig. 1, this embodiment provides a multi-modal network topology, which includes a backbone network part (KN) and a plurality of different types of network identification control domains, where the backbone network part (KN) includes a plurality of interconnected backbone-level multi-modal routing devices (KR), and the plurality of different types of network identification control domains are interconnected through the backbone-level multi-modal routing devices (KR), and the backbone-level multi-modal routing devices (KR) can simultaneously support routing of IP address identification, geographic location identification, identity identification, and content identification network packets. By the topological structure, local area network environment communication can be realized in each network identification control domain (namely, the local area network environment); wide area network environment communication between multiple different network identity control domains across the backbone (e.g., from network identity control domain 1 to backbone, and then from backbone to network identity control domain 2) may also be implemented. The backbone multi-mode routing equipment (KR) can simultaneously support the routing of IP address identification, geographic position identification, identity identification and content identification network data packets, so that different single-mode and mixed multi-mode wide area network environment communication becomes possible.
In this embodiment, fig. 2 is a schematic diagram illustrating an implementation of a control domain in a multi-modal network topology, according to an example embodiment. Each network identification control domain is provided with an intra-domain multi-mode routing switching Device (DR) which simultaneously supports IP address identification, geographic position identification, identity identification and content identification, a server and user terminal equipment. An intra-domain multi-mode routing switching Device (DR) which simultaneously supports IP address identification, geographic position identification, identity identification and content identification is configured in each network identification control domain, so that the network topology can support 4 modes to communicate in a local area network environment or wide area network communication crossing backbone networks in a single mode manner, and can also support communication in the local area network environment or wide area network communication crossing backbone networks under the condition that multiple modes exist in a mixed mode. The network identification control domain is provided with the server and the user terminal equipment, so that the diversity of network node types and the authenticity of the network are ensured, and the equipment requirements on the server and the terminal when various actual network service applications are operated are met.
In this embodiment, the network identifier control domains are 10 in number, and the configuration scheme is as follows: two IP address identification control domains (CD 1, CD 2), two geolocation identification control domains (CD 3, CD 4), two identity control domains (CD 5, CD 6), two content identification control domains (CD 7, CD 8) and two hybrid identification control domains (CD 9, CD 10).
Each single mode is provided with two control domains, so that the capability of developing a single-mode local area network environment communication experiment in one control domain and developing a single-mode wide area network communication experiment between two single-mode control domains crossing a backbone network can be provided, and interference factors possibly brought by mixing other modes can be effectively avoided, and the influence on the analysis of technical and experimental results can be avoided; for example: when a local area network communication test of IP address identification is expected to be carried out, only CD1 or CD2 needs to be selected, and a network data packet is sent in the CD1 or CD 2. When a wide area network communication test of the IP address identification is desired to be performed, the network data packet may be sent from the CD1 to the CD2 across the backbone network KN.
The two mixed identification control domains are configured, so that the capability of developing a mixed mode local area network environment communication experiment in one control domain can be provided, and the capability of developing a mixed mode wide area network communication experiment between the two mixed mode control domains crossing the backbone network can also be provided; for example: when a multi-modal local area network communication test with the 4 mixed modes is desired to be carried out, only the CD9 or the CD10 needs to be selected and the network data packet is transmitted inside the selected CD9 or CD 10. When a multi-modal wide area network communication test with a mixture of 4 modalities is desired, the network data packet may be selected to be sent from the CD9, across the backbone network KN, and to the C10.
The configuration method has the minimum network construction scale on the premise of meeting the requirements of flexible and diversified network communication modes, and is favorable for reducing the construction cost.
Further, the mixed identification control domain (CD 9, CD 10) comprises an IP address identification, a geographic position identification, an identity identification and a content identification.
Based on the above description, a multi-modal network topology, the usage mode thereof includes:
selecting an identification control domain from the CDs 1 to 8 for single-mode local area network communication can provide wide area network communication capability aiming at the range of the single-mode local area network, and test the technical support capability of multimode routing switching equipment (DR) and protocol in the domain to the single-mode local communication.
Two identification control domains with the same identification are selected from the CDs 1 to 8 for single-mode cross-backbone communication, wide area network communication capacity aiming at the single-mode cross-backbone can be provided, and technical support capacity of multi-mode routing switching equipment (DR), multi-mode routing equipment (KR) of the backbone and a protocol for single-mode remote communication in a test domain can be tested.
Selecting an identification control domain from the CD9 or the CD10 for multi-modal local area network communication can provide wide area network communication capability aiming at the range of multi-modal local area networks, and test the technical support capability of intra-domain multi-modal route switching equipment (DR) and protocol to multi-modal local communication.
By using the CD9 and the CD10 to perform multi-modal cross-backbone communication, the wide area network communication capability of the multi-modal cross-backbone can be provided, and the technical support capability of multi-modal remote communication by the intra-domain multi-modal routing switching Device (DR), the backbone multi-modal routing device (KR) and the protocol can be tested.
In the scheme, backbone network multi-mode routing equipment (KR) and intra-domain multi-mode routing switching equipment (DR) which simultaneously support IP address identification, geographic position identification, identity identification and content identification can be realized by adopting the existing data plane programmable network equipment (such as a P4 switch, which supports P4 language programming, thereby customizing a data packet forwarding rule and a processing rule).
By utilizing the method and the device, various experimental verifications aiming at the research of the multi-mode network related technology can be flexibly and effectively developed in a simplified mode, and good technical reference can be provided for the subsequent construction of a real network system in a real environment.
Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the application being indicated by the following claims.
It will be understood that the present application is not limited to the precise arrangements that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the application is limited only by the appended claims.
