Embodiment Construction

[0025] The MOCA system can be regarded as a layer 2 network device in terms of data forwarding, and the NC forwards data by querying the MAC address table. When a network loop occurs, it will cause broadcast storms or other network failures on the external network. like Figure 4 As shown, the method of the present invention detects and processes the MOCA system through the following steps to solve the above-mentioned problems:

[0026] (1) The NC sends Ethernet packets to the CPE at intervals, so that all online CPEs under the NC can receive the Ethernet packets. The Ethernet message can be, for example, a Layer 2 broadcast packet whose source address is the MAC address of the NC.

[0027] (2) Detect whether the received data packet contains the aforementioned Ethernet message.

[0028] (3) If the above Ethernet message is not included, it means that there is no loop phenomenon, and the above steps are repeated for detection. This loop detection is a continuous process, b...

Abstract

The invention discloses a MOCA system loop detection and processing method. The method sends an Ethernet message to a CPE at intervals through an NC, and detects whether the received data packet contains the above Ethernet message to determine whether the port is There is a loopback situation and the above problems are dealt with, timely solve the problems of user access to the network, avoid affecting the entire network, and notify the maintenance personnel in time to quickly locate and solve user network problems, which can make the MOCA system run more reliably and efficiently Maintenance is simpler.

Description

technical field [0001] The invention relates to a MOCA system loop detection and processing method, which belongs to the technical fields of network communication and radio and television. Background technique [0002] With the in-depth advancement of the two-way network transformation of radio and television, the rapid development of triple play, and the further advancement of optical fiber, EOC products have become the first choice for solving the last 100-meter transmission problem after optical fiber to the building, and MOCA technology is a high-speed Frequency EOC technology realizes the simultaneous transmission of TV and two-way data signals on a coaxial cable. It has the characteristics of high bandwidth and multi-service support, and has become the most widely used technology in EOC products. [0003] The MOCA system consists of figure 1 As shown, NC is the master node device of the MOCA system, which is usually placed in the corridor or at the optical node, and C...
