Data flow is unpredictable, and relentless. Spikes in network traffic result in microbursts or longer peaks which are a perennial problem for most packet brokers or aggregation switchdes which, by their very design, are deliberately over-subscribed. Available buffer capacity can easily be overwhelmed, resulting in lost packets.
MetaWatch brings an aggregated 300Gbps ingress down to a 20 Gpbs (2x10GbE) egress rate. Incoming frames are buffered in up to 32GB of memory within the device before being aggregated and delivered to downstream capture devices. Moreover, MetaWatch implements industry-standard IEEE flow control on egress ports, allowing congested downstream capture appliances to leverage the deep buffering available and "push back" rather than drop frames thus regulating the rate at which frames are delivered to them.
The MetaWatch application contains two 15:1 buffered, aggregated port group instances:
Benefits of MetaWatch deep buffering:
- absorb microbursts and over-subscription over an extended period;
- allow downstream capture devices to mitigate packet loss when they are
- increase over-subscription, reducing the number of expensive downstream capture ports
- significantly reduce the probability of dropped frames
- no need to continuously upgrade capture or analytics platforms to match growing data traffic demands.
Timing is critical in today's financial, cloud, security and HPC monitoring systems. It is important to be able to measure significant events as accurately as possible. MetaWatch's true 1ns timestamp resolution offers the best solution.
To give an example, timing and time synchronisation has been recognised as key to financial market transparency by regulators - be it in regards to the European MiFID II regulations or the US equivalent expected to move to similarly strict rules. ( >> Download our "MiFID II - Timestamping" Brief)
