MetaMux 48E

48 Port low-latency switch and FPGA platform

MetaMux 48E is a hybrid multi-layer switch designed for the most latency critical networks such as trading environments.

It is multiple switches in one – performing layer 1 switching in only 5 ns and multiplexing/aggregation in 56 ns, making it extremely useful for connecting trading machines directly to exchanges.

MetaMux is built on the same foundation as MetaConnect, so its layer 1 features include dynamic patching, tapping, one-to-many replication, media conversion, packet stats and precise timestamping. That means that the delay on downstream packets is barely detectable.

 

When using aggregation, packets can be multiplexed from many to one in 56 ns assuming no congestion, otherwise the packets are queued. That is a fraction of the latency and much more deterministic, compared with the best conventional switches.

 

Why use MetaMux?

  • Super fast multiplexing (many to one) with half the latency of the best conventional switches:
    • Order entry switch with 56 ns latency (assuming no congestion);
  • Layer 1 performance of MetaConnect:
    • Suitable for latency critical paths with 5 ns latency port to port;
    • Reconfigurable without rewiring - use as a patch panel or kill switch/circuit breaker;
    • Broadcasts one to many in 5 ns;
    • Ad-hoc tapping without rewiring;
    • Precise timestamping of packets;
    • Cost savings through the use of less expensive SFP+ and network media - e.g. convert fibre to copper;

Features and Benefits

Fast multiplexing Aggregate streams from multiple sources into a single stream for hand-off to exchanges, microwave links, or WAN links. Also configurable as multiple many-to-one multiplexers.
Integrated layer 1 switching Patching, media conversion, tapping replication and packet statistics. Wire-once to reduce visits to the data center. Use Layer 1 broadcast to implement a return path with a latency of just 5 ns and virtually no jitter.
Deterministic Replaces taps to monitor or share feeds such as market-data with full regeneration and no additional overhead.
Flexible SFP/SFP+ support Allows the use of less expensive modules, including direct attached copper cables, that are boosted by MetaMux's high performance signal recovery and regeneration.
Protocol flexibility Protocol agnostic at layer 1 while layer 2 packet features support 1GbE and 10GbE with 100M. 100M Ethernet and rate conversion are planned for a future software release.

Packet statistics 

Advanced monitoring. Captures high-level packet statistics across all ports. Supports detailed switch statistics via SNMP or CLI. Provides tcpdump and LLDP on every port. 

FPGA Development 

Flexible platform with all 48 ports connected to the onboard Xilinx® Ultrascale or Ultrascale+ FPGA(s) for custom applications

x86-64 Linux management 

Uses open standards platform and MOS operating software to provide user extensible solutions.
