Problems solved by technology

[0004] The above-mentioned data transmission method for avoiding service interruption needs to be realized through a standard routing protocol, and the implementation process is complicated. The continuity of the service is closely related to the convergence speed of the routing protocol. Due to the slow convergence speed of the existing routing protocol, the uplink The switching speed is at the level of tens of seconds, which cannot meet the application scenarios with strict requirements on service interruption time, such as the business continuity requirements of telecom services

Embodiment Construction

[0041] The data transmission system between telecommunication equipment based on point-to-point connection of the present invention is mainly composed of lower-level telecommunication equipment and multiple upper-level telecommunication equipment, and the lower-level telecommunication equipment is connected with multiple upper-level telecommunication equipment. The multiple uplink ports set are connected to multiple upper-level telecommunication equipment, and the lower-level telecommunication equipment is only connected to one upper-level telecommunication equipment through one uplink port, that is, there is a one-to-one relationship between the upper-level telecommunication equipment and the upper-level telecommunication equipment.

[0042] The above-mentioned multiple upper-level telecommunication equipments are in backup relationship with each other, that is, one of them is the main upper-level telecommunication equipment, and the other upper-level telecommunication equipmen...

Abstract

The invention discloses a data transmission system and method of point-to-point connection telecommunication equipment, which is characterized by the following: the lower telecommunication equipment connects primary higher telecommunication equipment and standby higher telecommunication equipment; the lower telecommunication equipment sends data to primary higher telecommunication equipment through ascending port; when the lower telecommunication equipment ascertains the higher communication is out of order, the higher telecommunication equipment is switched; the data is sent to the switched main higher telecommunication equipment by lower telecommunication equipment and ascending port which connects main higher telecommunication equipment. The invention realizes the reliability of data transmission net group, which improves the stability of telecommunication business,

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data transmission system and method between telecommunication devices based on point-to-point connection. Background technique [0002] Under normal circumstances, a lower-level telecommunication device is only connected to a fixed upper-level telecommunication device in the upstream direction, that is, a lower-level telecommunication device is only connected to one upper-level telecommunication device. When the uplink fails, or the physical connection between the lower-level telecommunication equipment and the upper-level telecommunication equipment is interrupted, user services will be interrupted. As a telecommunication device with telecommunication-level reliability, such service interruption cannot be tolerated. [0003] In order to avoid service interruption, it is usually necessary to ensure service continuity through routing convergence of standard routin...
