Description

[0001] METHOD AND APPARATUS FOR MONITORING NETWORK ERROR [0002]

The present disclosure relates to a method and apparatus for monitoring network errors in a network system.

Recently, with the increase of smart phones and the increase of demand for data traffic, mobile telecommunication operators are developing equipment and technology considering the influence of the system part and the effect to accommodate the increased data traffic in various ways.

Ethernet is a typical bus structure LAN (Local Area Network), and uses CSMA / CD (Carrier Sense Multiple Access with Collision Detection) for data transmission. The computer to which the data is transmitted first checks whether or not the communication network is in use, and then transmits the data if the communication network is not in use. If the network is in use, wait a certain amount of time and retest.

Gigabit Ethernet is an Ethernet standard that speeds up the transmission rate to 1 Gbps and is also called 1000Base-X. By increasing the transmission speed (10Mbps) of the Ethernet standard that connects multiple computers and networking, and increasing the transmission speed of the already-manufactured Fast Ethernet (100Mbps) to 10 times, the transmission speed of 1Gbps can be realized.

On the other hand, LAN switches that are not compatible with IEEE 802.3az, one of the Gigabit Ethernet standards, may be connected to Gigabit Ethernet. In this case, when an error such as a packet loss occurs due to a failure / malfunction of the LAN switch, the Ethernet service using the LAN switch may not be smoothly provided.
