We are a Software House specialising in eCommerce Solutions using Magento and WooCOmmerce. But now we have a need for a skilled Delphi Developer to help finish and update a product one of us built around 13 years ago using Delphi v5.

DPI analyzer generates stream of log messages in Syslog message or IPFIX format. Messages include information about applications identified by DPI (URL, MIME type, q-ty of bytes, packets, etc. ). Massages fields may vary based on application -URL may be indicated only in HTTP based applications. There are about 2,000,000 EPS (Events per Second) Size of message - 200 bytes From this numbers can be calculated that stream is 400 Mbytes / sec and 35 TBytes a day. These logs have to be processed in real time. Real time processing assumes aggregation by message fields. 1) Traffic per source address and application - every 1 or 5 minutes 2) Traffic for top 10 applications per source address - every 1 or 5 minutes 3) Traffic per source address and destination address - every 1 or 5 minutes 4). Traffic either by URL, hostname, MIME Type (for HTTP) - every 1 or 5 minutes There may be few addition similar aggregation processes. Logs will not be stored - only aggregated data. There should be possible to run various reports based on aggregated data. Type of reports: Traffic per source address - application per hour/day/week/month Traffic of Top applications per hour/day/week/month Details of aggregation fields and reports are not determined yet. After initial task there may be additional requested to do more aggregation and reports. Aggregation by different parameters should complicate the task and should be solved by just adding additional processing power and storage based on low cost hardware. This type of systems are usually being built based on frameworks like Apache Hadoop, Storm, Kafka etc. Please contact me if you have questions.
