Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a node device for resource reservation.
Background
Under the development trend of cloud computing and edge computing, computing power of many different scales can be distributed at different distances close to users in future society, and various personalized services are provided for the users through a global network. From a billion-magnitude intelligent terminal, to a billion-magnitude home gateway all over the world, to thousands of edge clouds with computing power brought by future MECs in each city, and to tens of large-scale cloud DCs in each country, a huge amount of ubiquitous computing power is formed, and the development trend of computing and network deep fusion is formed.
As shown in fig. 1, computing resources in the network are merged into each corner of the network, so that each network node can become a provider of the resources, and a user's request can be satisfied by calling the nearest node resource and is not limited to a specific node, thereby avoiding waste of connection and network scheduling resources. However, the traditional network is only a pipeline for providing data communication, and is based on connection, and is limited by a fixed network addressing mechanism, and often cannot meet higher and more rigorous QoE (quality of experience) requirements. In addition, with the development of micro-services, a traditional client-server mode is deconstructed, application deconstruction function components on a server side are distributed on a cloud platform and are uniformly scheduled by an API (application program interface) gateway, dynamic instantiation can be achieved as required, service logic in the server is transferred to the client side, the client side only needs to care about computing functions and does not need to care about computing resources such as service corr, virtual machines and containers, and therefore the function of serving as one server is achieved. Therefore, the requirements of network and calculation fusion evolution are cooperatively considered facing the future network, the global optimization of the network in the ubiquitous connection and computing architecture, the flexible scheduling of computing power and the reasonable distribution of services are realized.
In addition, the network demands for delay, bandwidth and delay jitter determinacy are provided for the productive internet service, but the IP is essentially statistical multiplexing + store and forward, and the problems of packet loss and delay uncertainty cannot be thoroughly solved despite the assistance of QoS (quality of service) and VPN (virtual private network) technologies.
At present, corresponding deterministic technical researches are carried out on a physical layer, a link layer and a network layer in a network. The physical layer typical technology Flexe technology schedules different services to different communication channels based on time division multiplexing, and realizes rigid isolation and resource guarantee of the services. The link layer TSN technology ensures time delay and certainty of time sensitive flow by using a series of technologies such as time synchronization, resource reservation, flow shaping and the like through the TSN, provides network guarantee for services borne by a small-scale network, such as vehicle-mounted and industrial control, and related mechanisms of the TSN are referred by a plurality of standardization organizations and are combined with a plurality of network technologies for application. The DetNet uses a series of service protection and forwarding technologies to ensure the reliable transmission of service flow, and provides possibility for ensuring the end-to-end network certainty of long-distance transmission service. However, the current deterministic study including TSN/detet/DIP is the certainty of network transmission path; the processing calculation delay of the node can not be guaranteed all the time, so that the real end-to-end deterministic service transmission can not be realized.
