We manufacture an Ethernet product that sits between a computer and the network. We need an inexpensive device to test our product and verify that it is working properly and not impacting the connection speed or throughput for uploads and downloads. Ideally it is a single device with two network connections that connect to either side of our product and has a simple display attached that indicates the test results: - Connected (Yes/No) - Input Connection Speed (10mbps, 100mbps, 1000mbps) - Output Connection Speed (10mbps, 100mbps, 1000mbps) - Upload Speed - Download Speed - Test Result (Pass/Fail) Additional features that would be desirable are: - Simple enough to send to a customer so they can check filters in isolation from the customer’s network environment. - An advanced version that would add additional tests (eg packet loss, bit error rate, sync loss count, etc.) and then allow our technicians to add the product serial number and print a test report.

for an IOT project, i am looking for someone who understand TCP socket programming. Who can set up a TCP server in the cloud ( Azure preferably ) for receiving data from the IOT device ( fleet device) and converting into HTTP/MQTT. Alternatively when the data is retreived, it could be stored and sent to external cloud using REST APIs. I am attaching the spec of the device

I am looking for someone who is able to implement CurveZMQ protocol in Erlang. This work will build on the existing Erlang implementation of ZMTP protocol found here: https://github.com/chovencorp/chumak 1. It should implement the CurveZMQ 1.0 protocol. 2. Implementation will be tested against other bindings (i.e. libcurve) to make sure it functions correctly. 3. Code clarity is preferred over performance. 4. The implementation MUST support ALL socket types specified in the ZMTP 3.1 protocol. 5. The code MUST work on Windows and Linux (i.e. not use any platform-specific libraries). This is a large project, so please only consider it if you have free time. Will NOT work with an agency - only directly with developers. Relevant references: 1. CurveZMQ 1.0 protocol: http://curvezmq.org/page:read-the-docs#toc23 2. ZMTP 3.1 Protocol http://rfc.zeromq.org/spec:37
