arp-scan
这里是源码实现。使用arp扫描局域网，相对于ping来说arp更准确，因为最新的Windows管理了默认响应ping的功能，而arp是网络的基础，如果支持ip协议则必须响应arp。这里是一个python版本。 -
Ninja
Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible. -
scapy
Scapy is a powerful Python-based interactive packet manipulation program and library.
It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, store or read them using pcap files, match requests and replies, and much more. It is designed to allow fast packet prototyping by using default values that work.
pypi上的介绍还提到了可以替代Wireshark：It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, wireshark, p0f, etc.).
这里介绍了scapy设计的一些思想，有点意思。 -
tcptrace
tcptrace is a tool written by Shawn Ostermann at Ohio University, for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump, snoop, etherpeek, HP Net Metrix, and WinDump. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and received, retransmissions, round trip times, window advertisements, throughput, and more. It can also produce a number of graphs for further analysis.

- MPLS Penultimate Hop Popping
以前一直以为PHP是只有LDP使用，通过这篇MPLS RFC文档描述，PHP是所有label distribution protocol都需要支持的，即包括LDP, RSVP-TE。对于SR-TE来说，是否封装倒数最后一跳的LSP，取决于ingress node或者控制器，实际来看是不封装的，也就是实现效果还是PHP，只不过不是倒数第二条弹出的，而是路径里面根本就没有。为了利用路径LSP，中国移动才提出了SR-TP的概念，在IETF中被称作path segment。path-segment不仅支持mpls,其实还支持srv6
