Embodiment 1

[0032] Embodiment 1 As an important network entity in the future Internet world, network middleware plays an important role in the Internet world. However, the application of network middleware often comes at the expense of destroying the hierarchical structure of the network, thus greatly challenging the openness and transparency of the Internet to new applications. To maintain the openness and transparency of the Internet, it is necessary to integrate network middleware into the network architecture. figure 1 It is a working flow chart of the implementation method of the converged network middleware according to a specific embodiment of the present invention, combining figure 1 As shown, in a specific embodiment, a method for implementing converged network middleware includes the following steps:

[0033] Step 101, perform service identification: use the Hash algorithm to assign a uniform and unique service identification for each resource to uniquely identify the resource,...

Embodiment 2

[0047] Example 2: In this example, figure 2 shows the packet format, image 3 shows the packet protocol header format, see figure 2 and image 3 As shown, the names and meanings of the fields in the data packet format and data packet protocol header format are as follows:

[0048] The service identification header is located between the IP header and the TCP header, and the service identification layer can be regarded as a sandwich layer between the network layer and the transport layer. The transport protocol header can be either TCP or UDP.

[0049] The "version" field indicates the version number of the mapping protocol; the "reserved" field reserves space for future applications; the 2-bit "T" field is used to indicate early resolution or late resolution, anycast late resolution or multicast late resolution, where 00 or 01 is used to represent early resolution, 10 represents anycast late resolution, and 11 represents multicast late resolution; the designed "destinati...

Embodiment 3

[0050] Embodiment 3: Name resolution is divided into early resolution and late resolution. Source routing can be regarded as early resolution, and hop-by-hop routing based on the routing table can be regarded as late resolution. The mapping system supports both early and late resolution. In the case of early resolution, the mapping system will return a series of connection information corresponding to the service ID for the application to choose. Late resolution is further divided into anycast late resolution and multicast late resolution, which perform routing based on service identifiers and forward data to corresponding service providers through the mapping server.

[0051] Such as Figure 4 As shown in the upper left, the process of early resolution is as follows:

[0052] Step 401, the client forwards the service identifier to the default mapping server;

[0053] Step 402, the mapping server forwards the request information to the mapping server storing the SID informa...

Abstract

The invention provides a method for implementing fusion of network middleware, which comprises the following steps of: allocating a unique service identifier for each resource by applying the Hash algorithm so as to uniquely identify the resources; selecting a name routing based on the Chord routing algorithm; performing name routing analysis; and performing network middleware fusion according to the network middleware strategy. The method for implementing the fusion of the network middleware guarantees network openness and transparency for new application, and can successfully fuse the network middleware into the Internet architecture. Therefore, the problems of Internet business and safety are effectively solved on the premise of not damaging the hierarchical structure of the Internet.

Description

technical field [0001] The invention relates to the field of Internet communication, in particular to a method for realizing Internet middleware fusion through name routing based on a distributed hash table. Background technique [0002] The Internet is a layered network, and each layer has corresponding entities and entity naming methods. Each layer entity has a corresponding Internet layer service identifier, so that the relationship between each layer entity and other Internet entity layers does not interfere with each other. However, the Internet, which is currently widely used in various industries, lacks a standard application layer identification. [0003] The original Internet was designed based on the end-to-end principle. The core network is only responsible for forwarding data packets, without detecting, filtering or changing the content of data packets. The service purpose will be realized at the edge of the network. This open and transparent design concept mak...
