Tcp Reassembly #303

Closed evanzhang87 closed 1 year ago

evanzhang87 commented 1 year ago

Hello, previously I was using google/gopacket for TCP stream analysis, but as the traffic increased, the performance of Golang did not meet my expectations, especially in terms of memory usage. So I decided to try doing the same thing using Rust. There is a critical part in my project which involves TCP Reassembly, but it seems that I cannot directly implement it within this project because there is no TCP packet parsing. I'd like to know if there are plans to support this aspect in the future.

I speak in my name, no at all the purpose of this project. Unfortunately I do not know any crates that do tcp reassembly, maybe https://github.com/smoltcp-rs/smoltcp do it.

As pcap is merely around libpcap it cannot do that. See here. @Stargateur has made a good suggestion on what you could use instead.
