Typical Application

2. Intelligent Traffic Processing Abilities

ASIC Chip Plus Multicore CPU

3.2Tbps intelligent traffic processing capabilities

100GE Acquisition

32*40/100GE QSFP28 ports Rx/Tx duplex processing, up to 3.2Tbps Traffic Data Transceiver at same time, for network Data Acquisition, simple Pre-processing

Data Replication

Packet replicated from 1 port to multiple N ports, or multiple N ports aggregated, then replicated to multiple M ports

Data Aggregation

Packet replicated from 1 port to multiple N ports, or multiple N ports aggregated, then replicated to multiple M ports

Data Distribution

Classified the incoming metdata accurately and discarded or forwarded different data services to multiple interface outputs according to white list, blacklist or user’s predefined rules.

Data Filtering

Input data traffic can be accurately classified, and different data services can be discarded or forwarded to the output of multiple interfaces by whitelist or blacklist rules. Flexible combination of elements such as Ethernet Type, VLAN tag, TTL, IP seven-tuple, IP fragmentation, TCP flag identification, message characteristics, etc. to meet the deployment requirements of various network security equipment, protocol analysis, signaling analysis, traffic monitoring and so on

Load Balance

Supported load balance Hash algorithm and session-based weight sharing algorithm according to L2-L7 layer characteristics to ensure that the port output traffic dynamic of load balancing

IP Datagram Reassembly

Supported IP fragmentation identification and supports reassembly of IP fragmentation so as to implement L4 feature filtering on all IP fragmentation packets. Implement traffic output policy.

UDF Match

Supported the matching of any key field in the first 128 bytes of a packet. Customized the Offset Value and Key Field Length and Content, and determining the traffic output policy according to the user configuration
