Number of streams

• 16384 transmit and 65535 trackable receive streams; stream fields can be varied to create billions of flows

Frame transmit modes

• Priority-based scheduler generates realistic traffic profiles per priority level, including mixed constant and bursty rate traffic to accurately simulate end user applications
• Modes include: continuous, single burst, multi-burst, timed burst, continuous multi-burst

Min/max frame size (w/CRC)

• 58-16384

Min/max Tx rates

• 1 packet per 3.43 seconds to 101% of line rate

Real-time Tx stream adjustments

• Change rate, frame length and priority settings without stopping the generator or analyzer for truly interactive, cause and effect analysis

Advanced per-stream statistics available in real time

Over 40 measurements tracked in real-time for each received stream including:

• Advanced sequencing: In-order, lost, reordered, late and duplicate
• Latency: Avg, min, max and short-term avg; first/last frame arrival timestamp
• Latency modes: LILO (forwarding delay per RFC 4689), LIFO (store and forward devices per RFC 1242) and FIFO (bit forwarding devices per RFC 1242)
• Data integrity: IP checksum, TCP/UDP checksum, frame CRC, embedded CRC and PRBS bit errors
• Histograms: Jitter, Inter-arrival, Latency, Sequence

Measurement timestamp resolution

• 10 ns with intra-chassis and inter-chassis synchronization

Supported encapsulations

• Layer 2: 802.3, Ethernet II, 802.1Q, 802.1ad, 802.1ah, 802.1Qay, FCoE, PPP
• Layer 3/4: IPv4, IPv6, TDP, LDP
• Tunneled: GRE, L2TP, MPLS, PWE3

Advanced per-stream statistics available in real time
