Embodiment

[0054] as attached figure 2 As shown, this embodiment provides an application layer adaptive data forwarding system that distinguishes real-time and non-real-time data streams, the system includes a data transmission scheduling module, hard disk storage, a temporary non-real-time data buffer, and a non-real-time data buffer. and several real-time data buffers;

[0055] The real-time data buffer is used to store real-time data received by the data port corresponding to the forwarding node;

[0056] The temporary non-real-time data buffer is used to store the data transferred from the non-real-time data buffer. The purpose is to undertake the temporary data buffering task when the non-real-time data transmission rate is too low, so that the data in the non-real-time data buffer can be stored in the hard disk;

[0057] The non-real-time data buffer is used to buffer normally received non-real-time data;

[0058] The data transmission scheduling module is used to take out the da...

Abstract

The invention discloses an application layer adaptive data forwarding system for distinguishing real-time and non-real-time data streams, belongs to the technical field of data forwarding, and aims to solve the technical problem of how to optimize application layer data forwarding based on an application layer and improve data forwarding performance. According to the technical scheme, the system comprises a data sending scheduling module, a hard disk storage, a temporary non-real-time data buffer area, a non-real-time data buffer area and a plurality of real-time data buffer areas; wherein the real-time data buffer area is used for storing real-time data received by a data port corresponding to the forwarding node; the temporary non-real-time data buffer area is used for storing data transferred from the non-real-time data buffer area; the non-real-time data buffer area is used for caching normally received non-real-time data; and the data sending scheduling module is used for taking out the data in the real-time data sending buffer area according to a specified strategy, checking a source address field and a target address field in the data packet application data unit, and forwarding the data to a next hop according to a routing table.

Description

technical field [0001] The invention relates to the technical field of data forwarding, in particular to an application layer adaptive data forwarding system that distinguishes real-time and non-real-time data streams. Background technique [0002] An overlay network is a logical network based on an existing physical network, so it has flexible deployment capabilities. Overlays use a specific encapsulation where one packet resides within another while being forwarded to a specific endpoint. On reaching the endpoint, the encapsulated packet is decapsulated. At present, there are various network protocols and solutions for overlay networks, including overlay networks based on application layers (such as P2P networks), virtual extensible LAN (VXLAN), generic routing encapsulation, and network virtualization overlay3 (NVO3). [0003] Application-layer-based overlay applications include content delivery networks (CDNs), QoS enhancements (eg, service overlay networks [Duan et al...
