Systems and methods for determining whether networked system migrations are successful are disclosed. In accordance with one method, a first set of properties of the networked system on a source platform in a first administrative domain is determined. Further, the method includes transferring the networked system to a destination platform in a second administrative domain. In addition, a second set of properties of the transferred system on the destination platform is determined, where the first and second sets of properties include functional properties and at least one of: performance properties, security properties or reliability properties. The method also includes outputting an indication that the transfer of the system to the destination platform is successful in response to determining that one or more of the properties of the second set are equivalent to corresponding properties of the first set.

Methods and systems for migrating networked systems across administrative domains

An all-optical transmission system includes an optical switch matrix, a plurality of optical components communicating over the optical switch matrix, and a top of rack (ToR) switch coupled to each optical component. Each ToR switch communicates with the optical components and with other ToR switches. The optical component includes a send circuit and a receive circuit with the send circuit having a ToR transceiver to receive data, a multiplexer coupled to the ToR transceiver, a Wavelength Selective Switch (WSS) coupled to the multiplexer, and a circulator coupled to the WSS.

Systems and methods for discovering configuration data are disclosed. In accordance with one method, network configuration tokens for a system are identified. Further, potential configuration files are obtained by identifying running processes in the system, restarting the processes and monitoring the restarted processes to discover files opened by the restarted processes. In addition, files that include the identified network configuration tokens are selected from the potential configuration files. Moreover, the method includes determining, by a hardware processor, that a given token from the identified tokens is a true token by replacing the given token with a test token in at least one of the selected files, restarting the identified processes that read the given token, and identifying a change in at least one of system call activity or network activity in the system.

Methods and systems for discovering configuration data

In one aspect, a system includes one or more electrical switches to transfer data in a data network; one or more optical switching groups coupled to each electrical switch, each switching group having one or more server racks, each server rack coupled to a top of rack (TOR) switch and an optical transceiver coupled to the TOR switch; and an optical switching unit (OSU) coupled to the one or more optical switching groups.
