Embodiment 1

[0053] Such as figure 1 — Figure 4 As shown, a multimedia service QoE resource allocation method, which includes the following steps;

[0054] S1: Design an SDN-based QoE resource allocation task model for multimedia services;

[0055] S2: Design an SDN-based multimedia service QoE resource allocation network model;

[0056] S3: Design the overall network utility function of SDN-based multimedia service QoE resource allocation;

[0057] S4: Propose an optimal network resource allocation algorithm that satisfies the overall utility function.

[0058] Wherein, the design process of step S1 is;

[0059] Taking audio and video streaming services as an example, the task model includes four parts: buffering (original source audio and video), encoding, forwarding (referring to a forwarding action running on a node) and playback (client). A service can be decomposed into a set of tasks described as a directed acyclic graph (DAG) of tasks, expressed as: G t =(T,E t ), T={1,2,.....

Abstract

The invention relates to the technical field of multimedia communication, and particularly relates to a multimedia service QoE resource allocation method. The method comprises the following steps: establishing a multimedia service QoE resource allocation task model, a network model and a network overall utility function based on an SDN, providing an optimal network resource allocation algorithm satisfying the overall utility function. In the method, the tasks are dynamically allocated to virtual network nodes to achieve end to end quality optimization. The method proposed in the invention canfind the best combination of network node functions. The network nodes can cooperate through negotiation to provide the terminal user with the optimized QoE and improve the overall net income of the network.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a multimedia service QoE resource allocation method. Background technique [0002] Software-defined networking realizes the separation of control plane and data plane, which makes network resource management easier, scalable, flexible and dynamic in the design, delivery and operation of network services. Therefore, the automation of network resource allocation, programmability and intelligent network control can be realized, and then a flexible and scalable network can be realized. For network operators, SDN significantly reduces capital expenditures and operating costs, integrates network resources through software, and realizes various network management and service configurations through software control. [0003] Existing methods ignore the previous cooperation of network nodes to realize the QoE resource allocation of multimedia services, which has limitati...
