The Accolade Technology ATLAS-2000 Service Node or ASN performs advanced flow and packet handling functions at 200Gbps. The ASN is designed for value-added functions that include deduplication, header stripping and packet slicing. It can be deployed in 2 different configurations:
1) In augmentation mode it serves as an adjunct to a Packet Broker with traffic coming in from a Packet Broker and U-turned on the same port once selected functions are performed. In this mode the ASN centralizes advanced packet processing, especially with Packet Brokers based on commodity Ethernet Switches resulting in significant cost savings. In addition the ASN architecture provides increased flexibility as multiple packet processing functions can run in one ASN and new functions can be seamlessly added as required.
2) With Inline mode the ASN sits in the traffic path and performs packet processing functions as traffic is flowing through the network. For example, in this configuration IP traffic can be filtered or scrubbed on-the-fly based on black or white lists thereby preventing malicious traffic from entering an enterprise environment.
