NetTAP® Network Traffic Capture by Network Packet Broker via
Network Visibility Platform for your Data Center
1. Background Technology
- With the rapid development of modern computer network technology,
the packet shunt device can quickly and accurately distribute the
massive data packets to each back-end server for further processing
based on the different five-tuple information of the packets
themselves.The efficient message shunt device is also the
foundation of some other high-level network special equipment (such
as firewall, virtual private network, load balancing equipment,
etc.).
- In a network environment, when the length of an IP message to be
transmitted exceeds the MaximumTransmiss1n Unit (MTU), an IP
message is divided into several IP messages, which are transmitted
separately.Shard packets occupy a considerable proportion in the
actual network environment, and due to the requirement of homology
and homology and the normal disorder of packets, it puts forward
high requirements for the processing of shard packets by the packet
shunt equipment.
- Under normal circumstances, each shard packet is transmitted on the
network in sequence according to their different positions in the
original packet. However, due to the complexity of the network
environment, the shard packet that should have arrived later
arrives at the destination device before the first one, which is
the shard packet disorder.In order to solve the disorder of shard
message, the device has to cache the disordered shard message, wait
for the arrival of the next shard message, and then forward the
first shard message along with the temporarily stored shard message
to the destination server of the back end according to the
five-tuple information of the first shard message.This may involve
the dump and management of cached shard packets, requiring
additional temporary storage space and additional processing time.
2. Product Background
The NetTAP® Network TAP with Nework Traffic Analysis Visibility to
Optimize Your Network, it is network data visualization control
device developed by Chengdu Shuwei Communication Co., Ltd.(short
as: NetTAP®) is a comprehensive product of the whole visual data
collection, data unified scheduling management, pretreatment and
redistribution.Network elements which can realize different
location, different exchange routing node link centralized
collection of data receiving, processing engine, through the
analysis of the device's built-in high-performance data will be
collected original data accurate identification, analysis,
statistical summary and tag, the original data redistribution
output, monitoring equipment to meet all kinds of analysis in data
mining, protocol analysis, signal analysis, security analysis, risk
control, etc. The required flow rate.
3. Intelligent Traffic Processing Abilities
Network Message Disitribution & Packet Distribution
A message splitting method based on multiple hash is characterized
as follows: the method USES two hash algorithms to calculate two
hash results respectively, USES one of the hash results to search
the result of the spatial primary table as the benchmark index, and
USES the other hash result to search the result of the spatial
subtable as the auxiliary index to modify the benchmark index.

5. NetTAP® Visibility Platform and Network Optimization.
- Network Traffic Capture Status Visibility(as following)
The data capture, packet capture of network traffic capture Points
are deployed in the key positions of the network for network data
acquisition and overall running status/trend control. Network Data
Deep Analysis, accurately present the proportion of each Network
Application.
- NetTAP® Network Optimization Solution
- More application for 25G/50G/100G, bandwidth crazy growing
- Virtualized cloud computing drives both north-south and east-west
traffic growth
- Main applications based on B/S architecture, with higher
bandwidth requirements, more interaction open, and business changes
faster
- Network operation and maintenance: single network management -
network performance monitoring, network backtracking, anomaly
monitoring - AIOPS
- More security management and control, such as IDS, DB Audit,
Behavior Audit, Operation and Maintenance Audit, Data-oriented
Management and Control,
Virus Monitoring, WEB Protection, Compliance Analysis and Control
- Network Security – from Access control, Threat Detection and
Protection to the core of Data Security
