Example Embodiment

[0044] The principles and features of the present invention will be described below with reference to the accompanying drawings. The embodiments are only used to explain the present invention, but not to limit the scope of the present invention.

[0045] like figure 1 As shown, it is a network scheduling method based on hybrid service transmission provided by an embodiment of the present invention. The method includes: S1, in a hybrid network, collecting burst services that carry bandwidth requests sent by a network control terminal and a network terminal; Wherein, a bursty service packet may include request bandwidth information, sending destination information, etc., and the bursty service packet type may be an FC bursty service frame or an IP bursty service frame.

[0046] It should be noted that the hybrid network in this embodiment may be a hybrid network of an IP network and an FC-AE-1553 network, and in other examples, other similar hybrid networks may also be used.

Abstract

The invention discloses a network scheduling method and system based on hybrid service transmission, and relates to the field of communication. The method comprises the following steps: in a hybrid network, collecting sudden services carrying bandwidth requests sent by a network control end and a network terminal; in a dynamic bandwidth allocation period, carrying out bandwidth allocation calculation on the bandwidth request of the sudden service through a dynamic bandwidth allocation algorithm, allocating a corresponding bandwidth to a corresponding time period of the sudden service accordingto a calculation result, and carrying out service scheduling on the sudden service according to the allocated bandwidth. A network scheduling problem under the IP and FC-AE-1553 service hybrid network is effectively solved, the packet loss rate of IP services is reduced, the network performance is improved, reasonable bandwidth allocation is achieved, and that all services in the dynamic bandwidth allocation period can be efficiently executed is ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network scheduling method and system based on mixed service transmission. Background technique [0002] With the characteristics of high bandwidth, low delay and high reliability, fiber channel technology is more and more widely used in domestic and foreign aerospace fields. FC-AE released FC-AE-1553, FC-AE-ASM, FC-AE-RDMA 5 kinds of protocol standards for avionics, FC-AE-1553 and FC-AE-ASM protocols are widely used at home and abroad. FC-AE-1553 is a command-response time-triggered protocol. With its high speed, high reliability, and support for real-time deterministic transmission behavior, it can build a deterministic network and is suitable for aerospace command control, data management, and data transmission of payload equipment. And so on, and the application is more and more extensive. Due to the flexibility of routing, IP communication technology is convenient for cr...
