Different from the legacy switching chips, the programmable switching ASIC inside the Asterfusion® PX NPB Switch can support software-defined parsing of new protocols and tunnel encapsulations，helping customers respond flexibly to various complex network environments.
Based on the programmable switching ASIC，Asterfusion® PX switch can not only carry out basic NPB functions such as traffic aggregation, distribution and replication but also support advanced packet processing functions like packet truncation, time-stamping, tunnel encapsulation/decapsulation, tunnel termination, etc at the wire-speed.
Asterfusion® PX switch can execute different traffic policies at the ingress interface, intermediate link and egress interface respectively. At the same time, it can support flow aggregation, distribution,, replication, load balancing and homology functions. It also has the flexibility to set multiple concurrent filtering policies from layers L2 to L7, which would greatly simplify the configuration process for network administrators when dealing with complex traffic policies.
Asterfusion® PX switch supports resilient flow load balancing mechanism. When a link in the load balancing group fails, this mechanism will just redirect the traffic on the failed link onto other links and at the same time ensure that the traffic on the original normal link will not be affected, and thus minimizing the impact of the link failure.
