Problems solved by technology

When there are too many routing nodes and routing entries and the routing differences between neighbors are large, a large number of LSAs are encapsulated into update packets for message exchange between routing nodes with adjacent relationships, which may cause link device congestion. And the link congestion causes problems such as the OSPF protocol cannot interact normally and routes do not converge.

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings.

[0029] The method provided by the present invention includes: the routing device obtains the data transmission rate of the link device through a self-defined protocol, and then calculates the maximum message transmission rate allowed by the link device according to the data transmission rate and the MTU of the interface interconnected with the link device Control the number of update packets sent by the OSPF protocol each time, so as to avoid the packet reaching the peak value of the link device in an instant and causing link congestion, and at the same time adjust the sending rate of update packets according to the success rate of sending update packets in the previous cycle Send the wrong line of the message. The technology of the invention can enhance the stability of ...

Abstract

The application discloses a method for sending narrow band link control update packets. The method comprises the following step: controlling the update packet sending quantity of an OSPF (Open Shortest Path First) protocol and adjusting an update packet sending rate to realize traffic smoothing of update packets. Through adoption of the technology disclosed by the invention, the stability of a routing protocol on a narrow band link can be enhanced on the basis of not influencing routing protocol functions; congestion of the packets on link equipment is avoided effectively; and normal receiving and sending of protocol packets and service data forwarding are ensured.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for sending an OSPF protocol control update message on a narrowband link. Background technique [0002] With the development of network technology, the proportion of IP-based data services in the network is also increasing. The future network will be a broadband convergence network with IP as the core. However, some narrowband links such as satellite links still need to support the application requirements of multiple IP services, so the ability to select IP routes is required. [0003] Routing protocols provide routing functions for IP data packets, and the quality of the routing process directly affects the efficiency of the entire network. Among them, Open Shortest Path First (Open Shortest Path First, OSPF) is a link-state-based protocol, and as a primary unicast routing protocol, an adjacency relationship must first be established betwee...
