Open Optical Monitoring RIPE 73 October 2016 Craig Thompson

Traditional Network Systems Applications OEM (Vertically Integrated) Monitoring Config & Automate QoS Security Other Forwarding SW (Traditional, Distributed, eg OSPF, BGP, STP etc) Forwarding SW (Centralized, eg OpenFlow) Switch Abstraction Interface (SAI) Installer (eg ONIE) Network OS Switch Silicon Here is a typical HW/SW stack for an Ethernet switch. Traditionally the integration of this was provided by the large OEMs. This has advantages and disadvantages. As optics suppliers at the base of the stack, we felt this the most. If we rolled out a new feature, or made a change, it take a year or two or more for this to reach the end-user. And even then, we wouldn’t get feedback unless something went wrong. It made it difficult to innovate, to get feedback from the users (such as yourselves) and improve the product.

This approach also has advantages and disadvantages. No longer is there one throat to choke if something goes wrong, unless its your own throat. But the open switch movement is very powerful and we feel it very directly as an optics vendor. Now you have choice, the ability to tailor to your own needs, to innovate, test, experiment, change rapidly. And while, there are many providers into this ecosystem, many choices, the sophistication of the solutions and the support of the solutions is improving every day.

The networking industry has been steadily marching towards open switch ports and direct deployment of optics for a number of years, and we’re now starting to see this happen broadly. But it takes a number of factors and things to fall in place for open switch optics to be viable. We’ll look at these one by one….

Open Optical Monitoring and Control (OOM) Applications API to Network Applications OOM was kicked off by the OCP Networking group in October 2015… To address problems with consistent access to Serial ID information on modules during OCP Interop testing.

What is Open Optical Monitoring (OOM)? A Python package, providing a standard API to read/write optical modules. EEPROM data encoded/decoded in key/value pairs. Same API: any NOS, any switch, any module vendor, any module type. Requires a simple shim to interface with the NOS. Open Source, easy to maintain, easy to extend. from oom import * for port in oom_get_portlist(): # enumerate the ports on the switch status = oom_get_memory(port, 'DOM') # DOM = voltage, temp, {TX, Rx}Power, bias print port.port_name + str(status) port0{'VCC': 3.30, 'TEMP': 23.55, 'TX_POWER': 0.57, 'RX_POWER': 0.56, 'TX_BIAS': 7.4} port1{'VCC': 3.31, 'TEMP': 24.02, 'TX_POWER': 0.57, 'RX_POWER': 0.53, 'TX_BIAS': 7.3}
