DAG 3.8S Dual port Network Monitoring Card

CoProcess or Application: IP Filtering

• Requires an Endace DAG CoProcessor expansion card that uses no additional bus slots.
• Receive, classify, and drop or capture packets based on network layer 2 and 3 header information. For example, packets can be captured based on IPv4 and TCP headers.
• Supports HDLC Packet-Over-SONET and Compressed PPP encapsulations.
• Allows for 8,192 filtering rules, with up to 4,096 active rules per port in dual port mode.
• Performs on the fly ’hitless’ rule changes with zero packet loss.
• Each rule allows every packet to be compared against a search key and dropped, captured or duplicated using either full or header only capture.

CoProcess or Application: ATM Adaptation Layer 5 (AAL5) Reasembly

• Requires an Endace DAG CoProcessor expansion card that uses no additional bus slots.
• Hardware based AAL5 Reassembly assists with the monitoring of highly utilized ATM links by shifting intensive computation from the CPU to the Endace DAG Coprocesssor.
• Supports up to 65,536 simultaneously active Virtual Paths (VP) / Virtual Connections (VC).
• Supports simultaneous reassembly of up to 65,536 AAL5 frames.
• Reassembly buffers are configurable between 2K and 64K bytes.
• Performs automatic VP/VC discovery and state management.
• Selected VP/VCs may be excluded by the application interface.
• Supports 100% cell reassembly on 2x OC3/STM-1c or 2x OC12/ STM-4c.
• Rich statistics, counters, and timeouts.
