JSON RPC API interface.
The Fusion L1 is enterprise ready, supporting SNMP for statistics gathering and TACACS+ to provide a variety of security access levels. Because the device operates at Layer 1, patches are fully secure, operate at line rate, and add negligible latency and jitter into the path.
Equipment vendors often require operators to use specific, branded transceivers or cables. This can make it difficult or impossible to interconnect devices of different brands, especially at the lowest latency.
The ExaLINK Fusion L1 can be used to connect nearly any type of SFP/SFP+ compatible transceivers together. e.g. branded/unbranded direct attach (DA) cables (10GBASE-CR), 850nm short and medium range multi-mode optical transceivers (10GBASE-SR), 1310nm long range optical (10GBASE-LR) and many others.
The device replaces expensive boutique media conversion solutions and adds signal quality, packet counting and header dump monitoring facilities with no throughput penalty and almost no latency penalty (<5ns). It can also be used for active capture to disk with the optional ExaLINK Fusion x86 module installed.
Complex networked systems require automated testing to ensure that they are production ready. The ExaLINK Fusion L1 allows operators to dynamically configure a range of network topologies and interconnects automatically for rigorous testing. The device can be programmed via the JSON RPC API and triggered by your continuous integration/testing software including TeamCity, Bamboo, and Jenkins. The ExaLINK Fusion x86 module provides a perfect device to configure, monitor and run these tests without needing additional rack space or resources.
Sometimes it is necessary to give clients direct access to the network, with nearly zero latency, but to control, monitor and block their access should anything go wrong. For example, brokers may want to give market participants direct connections to the exchange, but apply a circuit breaker or kill switch should the participant exceed their risk margins.The ExaLINK Fusion L1 provides <5ns latency for connections to external networks (e.g. WANs/exchanges). Taps can be used to send all forward and reverse traffic to a monitoring process which which may programmatically disconnect any client using the JSON RPC API interface when risk or security violations occur.
All network engineers care about reliability and resilience. Production networks typically have multiple redundant paths to handle link, switch, router or cable failure and usually have multiple redundant gateways/firewalls.
Using the ExaLINK Fusion L1, redundant links and devices can be connected using a minimum of switch hops and adding only a few nanoseconds of latency. The JSON RPC API interface can be used to programmatically change paths on gateway/firewall failure.
