Besides basic NPB functions such as replication, aggregation and load-balancing, FusionNOS can also supports complex NPB packet pre-processing functions, including packet time-stamping, payload obfuscation, SSL decryption, IP fragment reassembly, TCP packet reordering, packet truncation & de-duplication, tunnel encapsulation & decapsulation. With these rich NPB functionalities, FusionNOS can greatly improve the processing efficiency of back-end application systems and effectively reduce deployment complexity and total CapEx.
