An Entity-Based Network Architecture Modeling Method

Abstract

The invention discloses an entity-based network architecture modeling method. The method comprises the steps that members in a network architecture are abstracted as network entities, and the network entities can be divided into an environment entity, service entities, protocol entities, a link entity, a channel and a port according to the grain size of the entities; the port is responsible for transmitting data, the channel is responsible for transmitting control information, the protocol entities provide protocol logic processing service, each service entity comprises one or more protocol entities and provides network service by organizing and managing different protocol entities, and the link entity provides abstraction and description of physical link functions; and the environment entity comprises the service entities, the link entity and subenvironment and provides environment for the communication among the service entities. With the entity-based network architecture modeling method, not only can the traditional hierarchical architecture be modeled, but also the novel network architecture can be modeled, compared with other methods, the entity-based network architecture modeling method is more flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of computer networks, relates to network architecture, and in particular to an entity-based network architecture modeling method, which can be used for existing network architecture based on ISO / OSI reference model and TCP / IP model Modeling can also be used to model novel network architectures. Background technique [0002] Network architecture refers to the overall design of the network communication system, which provides reference standards for network hardware, software, protocols, access control and topology. Usually when describing the architecture, the network architecture is generally regarded as a collection of layers and protocols. Generally, the reference model of Open System Interconnection (OSI) proposed by the International Organization for Standardization (ISO) in 1979 and the TCP / IP model of the Internet are adopted. The OSI reference model describes the structure of the network with seven ...

Problems solved by technology

However, in recent years, as the Internet has entered a stage of vigorous development of applications and services, the three major problems facing the network in resource control, service customization, and user management have become increasingly prominent, and the defects and shortcomings of the traditional network architecture have also gradually emerged: lack of Efficient resource control capabilities; weak service customization capabilities cannot meet user needs; user management in the Internet creditless environment is becoming more and more difficult
