MetaMux is a network application designed for Arista's FPGA-enabled switches performing multiplexing/aggregation of incoming streams in an average of 39 ns*.


Arista MetaMux 7130 Application
?

The MetaMux application provides a configurable number of multiplexer (mux) options all the way from 48:1 down to multiple 4:1 mux instances. To allow for the situation where multiple packets arrive at the multiplexer at the same time, Metamux will queue packets in input buffers to ensure contending packets can be sent on the link. Buffer utilization and statistics are available from the device.

MetaMux performs packet multiplexing with significantly lower latency than the best conventional switches, making it extremely useful for connecting trading machines directly to exchanges, for example. Its latency is significantly lower whilst offering the same level of industry standard monitoring and management as traditional switches.

Features Benefits
Ultra-fast Multiplexing in 39 ns Aggregate streams from multiple sources into a single stream for hand-off to exchanges, microwave links, or WAN links. Configurable as many N:1 multiplexers.
Deterministic Know and rely upon your system's latency for fairness, or to get the best execution environment for all your orders. Without contention MetaMux aggregation latency varies by +/- 7 ns.
Complete Packet Statistics Receive per port counters from the MetaMux application and the Layer 1 switch; useful for accounting, statistics, diagnosis and troubleshooting for both ingress and egress.
Support for BGP and PIM* Exchanges may require a Layer 3 network device supporting BGP and PIM.
Easy to Monitor and Manage Arista provides a complete range of additional features including:
  • A comprehensive set of Ethernet counters on each port
  • An integrated Linux management processor
  • Streaming telemetry via a local InfluxDB tick database
  • Web-based Graphical User Interface (GUI)
  • Command-line interface (CLI) via secure shell (SSH), Telnet, serial connection
  • Local and remote logging via Syslog
  • JSON-RPC API
  • Simple network management protocol (SNMP) v1, v2, v3
  • Support for NETCONF
