PacketDam is a cost-effective software solution against DDoS. It runs on off-the-shelf hardware and fits any budget or deployment scenario.

pcapfix is a repair tool for corrupted pcap and pcapng files. It checks for an intact pcap global header and packet block and repairs it if there are any corrupted bytes. If a header is not present, one is created and added to the beginning of the file. It then tries to find pcap packet headers or packet blocks, and checks and repairs them.
dabba is a set of distributed network monitoring tools for Linux. Its main use is to gather or scatter actions on a network such as traffic capture, replay, generation, or monitoring. It was inspired by the Dabba Walla system in Mumbai where meals are regrouped and dispatched throughout the city with a high efficiency rate, every day of the year. The project has three main components: libdabba, a low-level zero-copy network library, dabbad, a multi-threaded task manager and IPC query processor, and dabba, a CLI for communicating with dabbad and submitting tasks.
