Pathload is a tool for estimating the available bandwidth
of an end-to-end path from a host S (sender) to a host R (receiver).
The available bandwidth is the maximum IP-layer
throughput that a flow can get in the path from S to R,
without reducing the rate of the rest of the Traffic in the path.

The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network Traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`

At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest Traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.
DSR-UU is a DSR implementation that runs in Linux and in the ns-2 network simulator.
DSR-UU implements most of the basic DSR features specified in the DSR
draft (version 10). One big exception is flow extensions.
DSR-UU does NOT use ARP, so do not be surprised if you do not see ARP
Traffic. DSR-UU instead uses its own neighbor table that sets up the
MAC-to-IP translation during route discovery.
在網絡安全中經常會遇到rootkit，NSA安全和入侵檢測術語字典( NSA Glossary of Terms Used in Security and Intrusion Detection)對rootkit的定義如下：A hacker security tool that captures passwords and message Traffic to and from a computer. A collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network,mask the fact that the system is compromised, and much more. Rootkit is a classic example of Trojan Horse software. Rootkit is available for a wide range of operating systems.

Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network.
Toolbox contains also scripts for defining network structures (random networks, user defined networks) and Traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for Traffic matrix creation).
This is a simulator written in Tcl to simulate a network node carrying GSM and GPRS Traffics with QoS mechanisms. The payload type including circuit-switched voice, VoIP and web Traffic, and the performance including packet drop, delay can be analyzed. The implemented QoS mechanism is DiffServ, with 4 RED queues for different services with different priorities.
