Net Optics Confidential and Proprietary iLink Agg xStream Intelligent Access and Monitoring Architecture Solutions

Net Optics Confidential and Proprietary Gigabit Monitoring Access Challenge Provide efficient, line-speed, passive monitoring access to traffic on 10 Gigabit network links for 10 Gigabit and 1 Gigabit monitoring tools

Net Optics Confidential and Proprietary 33 Solution Requirements A 10 Gigabit monitoring infrastructure requires: Line-speed, passive traffic access Non-blocking architecture with zero risk of disrupting traffic or impacting network performance Low and predictable latency to support performance analysis Ability to apply a variety of 10 Gigabit and 1 Gigabit monitoring tools working from a centralized NOC

Net Optics Confidential and Proprietary 44 The iLink xStream Solution RequirementiLink Agg xStream Feature Line-speed, passive traffic access240 Gbps non-blocking throughput Zero risk of disrupting traffic or impacting network performance Passive deployment architecture – does not touch the network traffic Low and predictable latency to support performance analysis Cut-through architecture delivers 600ns latency, 50ns jitter – the lowest in the industry Ability to apply a variety of 10 Gigabit and 1 Gigabit monitoring tools working from a centralized NOC 24 SFP+ ports (10G / 1G) Switching, aggregation, Remote management iLink Agg

Net Optics Confidential and Proprietary 55 Cut-Through for Low, Predictable Latency 1. Traditional store-and-forward architecture – packet completely received before transmit begins 2. Cut-through architecture – packet starts transmitting after 128 bytes are received Packet Traditional switch Packet iLink Agg xStream Latency: 2us (64B packet) to 12us (9600B packet) Latency: 0.6us (64B packet) to 0.65us (9600B packet) 64 to 128 bytes 64 to 9600 bytes
