Flow Aggregation and Regeneration

Wire-speed 10 GbE, 40 GbE, and 100 GbE flow filtering and forwarding on ports in a single line card or across several line cards:

• Map bidirectional (uplink and downlink) flows to the same network port
• Replicate flows from any network port to any tool port on the same or different line cards
• Aggregate flows from multiple 1 GbE, 10 GbE, or 40 GbE network ports to a single 10 GbE, 40 GbE, or 100 GbE tool port
• Distribute flows from one 10 GbE, 40 GbE, or 100 GbE network port across multiple 1 GbE, 10 GbE, or 40 GbE tool ports
• Selectively forward flows from 10 GbE, 40 GbE, and 100 GbE network ports to lower-speed tool ports
• Mirror flows across tool ports
• Dual, concurrent IPv4 and IPv6 stack support
• Burst protection with buffering on network ports

Mobile (Layer 7) Flow Optimization

Stateful optimization of mobile bearer and control flows:

• GTP correlation
• Subscriber (IMSI) aware forwarding
• Inter Radio Access Type (IRAT) transfer aware forwarding
• Bearer flow deduplication (based on inner IP payload)
• Automated mobile network topology learning

Flow Filtering

Flow selection and filtering configurable on a per-tool basis, based on:

• Layer 2, 3, and 4 criteria (5-tuple)
• Deep-packet (up to 128 bytes) pattern matching
• GTP outer and inner headers
• Packet length
• International Mobile Subscriber Identity (IMSI)
• VLAN tags

Load Balancing

Balance traffic load across multiple egress ports based on:

• Round-robin packet distribution
• IP hash
• GTP TEID and payload (inner) IP address
• International Mobile Subscriber Identity (IMSI)

Layer 2-4 Flow Optimization

Packet modification features for optimized flow delivery:

• MPLS label and VLAN tag stripping
• Port labeling
• Packet slicing
• Time stamping
