| | - Output all ports -> unclear how test data should look like | |
| | - Found out broad/multicasting in theory -> bitmask | |
| | | |
| | - HW test compiling for 2 days | |
| | - HW test | |
| | * compiling for 3 days | |
| | * Execution fails due to missing djtgcfg | |
| | | |
| | Payload to control plane | |
| | - digest not possible due to missing | |
| | - might work with working | |
| | | |
| | Next steps: | |
| | - Debug ioctl errors when writing table entries | |
| | | |
| | - Understand HDL or PX user engines for writing checksum part | |
| | - Adjust controller to digest | |
| | | |
| | HDL notes | |
| | - cycle limitations | |
| | - variable length might be a problem | |
| | | |
| | Next steps after discussion: | |
| | | |
| | - checkout ipv6 test on netpfga / modify v6 packet | |
| | - checkout whether diff is possible on checksum -> see ttl | |
| | - checkout externs of Hendrik / report | |
| | - Asses checksum difficulty | |
| | | |
| | Handing in thesis: | |
| | | |
| | - Email pdf | |
| | - code on github | |
| | - tar.gz of the code | |
| | | |
| | - Decleration of -> from tobias | |
| | - Week after: presentation | |
| | | |
| | | |
| | - 15m talk | |
| | - 15m q&a | |
