Problems solved by technology

However, for the media server, this technology has certain restrictions on the application. The client and server that transmit the heartbeat signal must use the same protocol, and the media forwarding board usually needs to be connected to the switching device to realize external For communication services, there is a device difference between the switch and the media forwarding board, so heartbeat packets cannot communicate with each other.

Embodiment Construction

[0035] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0036] The link detection scheme based on the ARP protocol of the present invention detects by transmitting ARP learning messages, including ARP request messages and ARP response messages, between the external network port of the media forwarding board of the media server and the switch connected to it. Whether the link between the external network port and the switch is normal.

[0037] The present invention is based on the link detection method of ARP agreement such as figure 1 shown, including:

[0038] Step 101, generate an ARP request message according to the configuration information of the external network port of the media forwarding board in the media server, and send it to the switch connected to the external network port.

[0039] Step 102: After receiving the ARP request message, the switch returns an A...

Abstract

The invention discloses a method for detecting a link based on an ARP protocol, comprising the following steps: generating an address resolution protocol (ARP) request message according to configuration information at the external network port of a media forwarding single plate in a media server; sending the address resolution protocol (ARP) request message to an switch connected with the external network port; returning an ARP response message to the external network port after the switch receives the ARP request message; and detecting the link between the external network port and the switch according to the ARP response message. The invention also provides a system for detecting the link based on the ARP protocol; the method and the system of the invention are suitable for link detection between the media forwarding single plate in the media server and an external load bearing network switch.

Description

technical field [0001] The present invention relates to link detection technology, in particular to a link detection method and system based on Address Resolution Protocol (ARP, Address Resolution Protocol). Background technique [0002] In the media server application based on the Transmission Control Protocol / Internet Protocol (TCP / IP, Transmission Control Protocol / Internet Protocol) network, the media forwarding board needs to communicate with the external bearer network through the switch to realize the transmission of signaling and media messages and forward processing. Before transmission and forwarding, in addition to checking whether the status of the physical network port connected to the media forwarding board and the bearer network is normal, it is also necessary to check whether the bearer network link connected to the network port of the media forwarding board is reachable. For network ports that are not reachable by the network, packet transmission and forward...
