Example 2
In this embodiment 2, a resource management method suitable for a multi-mode network is provided, so as to implement effective addressing and state sensing of various network resources in the whole network. Specifically, the multi-mode network schematic diagram is shown in fig. 1, and is composed of a core network supporting a plurality of different modes and a plurality of edge networks. The core network is mainly responsible for controllable intercommunication and data transmission between multi-mode edge networks, and the edge networks provide access and communication services for users (terminals or servers and the like) in different modes. The forwarding plane of a multi-modal network mainly comprises two types of entities, namely forwarding equipment and access terminals. The forwarding equipment is directly managed by a network operator and is used for efficiently forwarding various information streams; the access terminal may be further divided into a host and a server that interact as a requester and a replier of data to generate the information flow.
In a multi-mode network, in order to facilitate addressing and sensing of various resources in different network domains, a hierarchical network knowledge base with an identifier as an index is constructed and used for recording attribute information and state information of the resources under each network. The local knowledge base of the edge network is used for recording the attribute and state information of various forwarding devices governed by the local knowledge base, the position and service information of the access terminal and reporting relevant addressing information to the global knowledge base of the core network; the global knowledge base of the core network needs to effectively manage multidimensional resources of the core network, store addressing information about devices, terminals and services provided by the knowledge base of the edge network, and provide query interfaces or active pushing to other edge networks.
Specifically, the interaction flow of the network forwarding device and the affiliated network knowledge base is as follows:
s1, after network forwarding equipment is started, registering an initial DID of the network forwarding equipment to a network knowledge base through a control link;
s2, the network knowledge base checks whether the DID of the network forwarding equipment is repeated with the DID of the registered equipment; if the DID is repeated, informing the network forwarding equipment that the registration fails and requesting the network forwarding equipment to regenerate the DID, and then registering; otherwise, replying that the network forwarding equipment is successfully registered and requesting the network forwarding equipment to continuously register relevant DD information;
s3, registering DD information to a network knowledge base by the network forwarding equipment, wherein the static information mainly comprises hardware parameters of the equipment, such as a processor, a memory, interface specifications and the like; the dynamic information mainly comprises configuration information, running state information and neighbor reachability information of relevant addresses.
The address configuration information is used for indicating the home network where the current forwarding device is located and the interface address corresponding to the mode where each interface is located, and the following modes { DID: HID, inf } 1 {PID 1 -LID 1 ,PID 2 -LID 2 ,…},Inf 2 {PID 1 -LID 1 ,PID 2 -LID 2 …, …;
the running state information is used for indicating the interface forwarding state of the current forwarding device, namely the average throughput of each interface within a certain time and the average throughput of each interface under each mode, and the following mode { DID { Inf } 1 -TH 1 :PID 1 -TH 1 ,PID 2 -TH 2 ,…},{Inf 2 -TH 2 :PID 1 -TH 1 ,PID 2 -TH 2 …, ….
The neighbor reachable information is used for indicating the connection relation between the current forwarding equipment and the neighbor thereof by periodicalThe transmitted Hello packet detects the neighbor nodes on each interface and records the round trip delay between them, which can be the following mode { DID: { Inf } 1 ,DID 1 ,RTT 1 },{Inf 2 ,DID 2 ,RTT 2 And ….
Because the forwarding equipment is directly administered by the home network, various information of related resources only need to register or update with the knowledge base of the home network. For the edge network, the local network knowledge base does not need to announce the related information to the global knowledge base of the core network.
The interaction flow of the access terminal and the access forwarding device and the network knowledge base thereof is as follows:
s1, an access terminal initiates an access request to an access forwarding device thereof and informs the access terminal of TID, PID and related authentication information thereof; if the access terminal also needs to provide business service, the corresponding BID is also needed to be provided;
s2, after the necessary authentication is completed, the access forwarding equipment allocates corresponding LID for the access terminal according to the mode supported by the access terminal, and registers the binding relation of the TID-PID-LID/-BID of the access terminal to a local knowledge base of the network; wherein, each terminal has LID, if the terminal also provides a certain service, the service is identified by BID, then BID needs to be registered;
s3, the local knowledge base stores the received relevant information and records the supported modes and the access positions of the access terminal;
s4, in order to realize the global addressing of the access terminal, the local knowledge base of the network needs to continuously register the position information of the access terminal, namely TID-HID-PID-LID/-BID, to the global knowledge base of the core network, so that other networks can learn the access network, supported modes, specific positions and provided business services of the access terminal;
s5, the core network knowledge base informs the local knowledge bases of all other edge networks of relevant registration information.
S6, when the access terminal moves, the new access forwarding equipment updates the position information of the access terminal to the local knowledge base of the network, and the new access forwarding equipment needs to continuously update the position information of the access terminal to the global knowledge base of the core network after receiving the position information.
The network forwarding device and the access terminal update their state information to the network knowledge base in a periodic and triggered manner, i.e. actively send update messages at intervals or when a certain option exceeds a threshold value. In addition, the network knowledge base can also query the relevant states of the network forwarding equipment and the access terminal at any time.
In addition, in order to realize the resource interview of different mode access terminals, the following resource virtual mode mapping method is designed:
s1, after accessing to the network, an access terminal registers the resource information of a single mode to a network knowledge base to which the access terminal belongs;
s2, the network knowledge base aggregates local resource information and distributes other mode identifiers supported by the network for the access terminal of each mode;
s3, reporting all resource information of a local original mode and a virtual mode to a global knowledge base of a core network by the network knowledge base, and realizing effective addressing under a global multi-mode by means of the resource information;
s4, the core network knowledge base informs the local knowledge bases of all other edge networks of relevant resource information.
