Problems solved by technology

However, most of these achievements are based on combination rules or artificial intelligence for service composition and path selection, and these methods are only designed for a single functional requirement and a single service request, without considering the dependencies between service instances, and cannot satisfy multiple requirements. Requirements for service routing selection in the case of goal-constrained multiple service requests

Embodiment 1

[0054] Embodiment one, see figure 1 As shown, a network service path selection system includes a service analysis module, a network construction module, a path detection module, a service combination module, a network reconstruction module,

[0055] The service analysis module includes a demand analysis agent unit, a network meta-service database, and a feature analysis unit. The demand analysis agent unit is used to query the network meta-service database and analyze the types and quantities of meta-services required by business service requests. The feature analysis unit is used to Responsible for analyzing the sequence and dependencies between meta-services, and constructing service request chains;

[0056] The network construction module includes a node discovery agent unit, a reconfigurable service node database and a bearer network construction agent unit. The node discovery agent unit is responsible for querying the reconfigurable service node database that meets the re...

Embodiment 2

[0060] Embodiment two, see Figure 1~3 As shown, it is basically the same as Embodiment 1, except that the service path evaluation standard refers to the use of the service path evaluation function Q path =f(P si , BW si ,D si ), according to the processing capability P of the meta-service of the node on the service path si , link bandwidth BW si and the end-to-end delay index D si Evaluate the service quality of the service path searched by the probe; perform selective processing on the probe specifically refers to: the node receives the path query probe, and performs the following operations according to the probe information: whether the current search service path meets the requirements of the service request chain , the service request chain requirements include resource requirements and meta-service requirements, if not satisfied, the node discards the probe, otherwise, judge whether the node provides any meta-service in the service request chain, if not, the node d...

Embodiment 3

[0062] Embodiment three, see Figure 4 As shown, a network service path selection method includes the following steps:

[0063] Step 1. Perform feature induction and demand analysis on the business service request, query the network meta-service database, and obtain the corresponding service request chain;

[0064] Step 2. Query the network service topology map, perform keyword-based service node retrieval on the reconfigurable service node database according to the resources in the service request chain and meta-service requirements, and obtain a set of candidate nodes in the network that meet the requirements of the service request chain;

[0065] Step 3. Establish a service bearer network for service requests according to the connection relationship and construction criteria of the candidate node set;

[0066] Step 4. According to the distributed selection detection mechanism, the target node of the service request sends a path query probe to the adjacent node that meets t...

Abstract

The present invention relates to a network service path selection system and a selection method thereof. The method includes: inductively analyzing service requests and obtaining service request chains; querying network service topology diagrams to construct service bearer networks; querying target nodes and generating query probes The needle is spread and forwarded to the adjacent nodes in the service bearer network that meet the requirements of the service request chain; the intermediate node of the service bearer network selects and processes the query probe; according to the stored information of the probe, the probe is forwarded to the service request node after satisfying the path search; The request node sends a confirmation probe to the service path and reserves resources; allocates and combines the service resources of each node to build a set of meta-services; detects changes in service requirements and evaluates the remaining service resources, and marks key nodes; Reorganize and refactor according to the structural principles to release occupied resources. The invention can meet the requirement on network resources when multiple service requests coexist, and improve the utilization efficiency of network resources.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a network service path selection system and a selection method thereof. Background technique [0002] As we all know, it is very difficult to add new functions and services to the core network due to the "rigidity" of the current Internet architecture. The traditional Internet based on end-to-end design places almost all network intelligence on end hosts, while the core network only provides simple store-and-forward services. This "edge intelligence, simple core" design constitutes the simplicity of the Internet architecture, which is compatible with the network application scenarios at that time. However, the commercialization of the Internet, ubiquitous and heterogeneous application environments, emerging communication modes, and security and management challenges all require the Internet to provide diversified services, not just store-and-forward services. In respo...
