Rong Teng network shunt acts on the front end of network monitoring in the field of network security. What are the main means of traffic monitoring? Let's talk about it today!

Support 48 10G or replace internal daughter cards, support 4 100G, support different links, LAN,GE,WAN,POS, etc.

What are the means of traffic monitoring, and what is the difference between RMON and SMON?

SMON is used for switched networks, while ROMN is used for shared networks.

Why is there RMON technology? what are the defects of SNMP for traffic monitoring?

Poor real-time, frequent polling will produce huge network traffic, resulting in communication congestion, or even congestion. The management computer resources are limited, but the task is heavy (centralized).

How many components does the RMON model have?

RMON management station, RMON agent / detector, monitored network.

What are the advantages and functions of RMON?

Advantages: load balancing (traffic monitoring tasks are distributed to RMON agents of each network segment), saving bandwidth (less communication times: when NMS needs to know the traffic of a certain network segment, data packets are transmitted between NMS and probe only; small packets: the data packets transmitted between NMS monthly probe are only SNMP commands, and the results of knowledge statistics and analysis of packets transmitted by NMS to probe).

Function: ask Titus from the main body. Offline operations, proactive monitoring, problem monitoring and reporting, provision of value-added services, multi-management station operations.

Support 160G 10G and 48100G, Rong Teng Mobile Internet signaling collection, IPV4IPV6 double parsing, user association success rate 99%

The difference between RMON1 and RMON2?

RMON provides monitoring of the physical layer and Mac layer, and RMON2 provides monitoring of the OSI above the data link layer.

What are the disadvantages of RMON for traffic monitoring?

Impossible network monitoring tasks: switch point-to-point communication, VLAN communication, QoS communication, link aggregation.

What are the ways to implement SMON? Pros and cons?

Port copy / mirror, backplane listening.

What is the difference between SMON1 and SMON2?

The difference is similar to RMON1 and RMON2.
