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, in future society, computing power of a plurality of different scales can be spread at different distances close to users, and various personalized services can be provided for the users through a global network. From intelligent terminals of billions to home gateways of billions worldwide, thousands of edge clouds with computing power brought by future MECs in each city, and billions of large cloud DCs in each country, massive ubiquitous computing power is formed to access the Internet from everywhere, and development trend of computing and network depth fusion is formed.
As shown in fig. 1, computing resources in the network are integrated into each corner of the network, so that each network node can be a provider of resources, a user's request can be satisfied by calling the nearest node resource, and the request is not limited to a specific node, thereby avoiding waste of connection and network scheduling resources. Traditional networks, however, are merely pipes for providing data communication, are based on connection, and are subject to a fixed network addressing mechanism, which is often not satisfied under the requirements of higher and more severe QoE (quality of experience). In addition, with the development of micro-services, the traditional client-server mode is deconstructed, application deconstructed functional components on the server side are distributed on a cloud platform, and are uniformly scheduled by an API gateway, so that dynamic instantiation can be realized on demand, business logic in the server is transferred to the client side, and the client side only needs to care about the computing function, but does not need to care about computing resources such as a server, a virtual machine, a container and the like, thereby realizing the function as one server. Therefore, the demands of network and computing fusion evolution are cooperatively considered for future networks, and the global optimization of the networks in the ubiquitous connection and computing architecture, the flexible scheduling of computing power and the reasonable distribution of services are realized.
In addition, delay, bandwidth and delay jitter deterministic demands are put forward on the network for productive internet services, but the IP nature is 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.
Corresponding deterministic technical research is currently occurring at the physical layer, the link layer and the network layer in the network. Wherein, the FlexE technology is based on time division multiplexing to schedule different services to different communication channels, thereby realizing rigid isolation and resource assurance of the services. The link layer TSN technology ensures time delay and certainty of time sensitive flow by using a series of time synchronization, resource reservation, flow shaping and other technologies through the TSN, provides network guarantee for small-scale network bearing service, 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 techniques, etc. to ensure the reliable transmission of the service flow, and provides possibility for the end-to-end network deterministic guarantee of long-distance transmission service. However, current deterministic studies include that TSN/Denet/DIP are all deterministic of network transmission paths; the processing calculation time delay of the node is not guaranteed all the time, so that the real end-to-end deterministic service transmission cannot be realized.
