Bandwidth is primarily a memory bandwidth benchmark, but it can also measure network bandwidth. It measures the maximum memory bandwidth of each part of the memory system, including main memory, L1, L2, and L3 caches, framebuffer memory, and register-to-register. For many tests, it performs both sequential memory accesses as well as random memory accesses to provide a more real-world performance estimate. The tests support Linux (Intel), Windows/Cygwin, and Mac OS X. Its core routines are in assembly for x86 and x86-64 architectures with both SSE4 and AVX support. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
ipband is a pcap-based traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if the specified threshold for a specific subnet is exceeded. This utility could be handy in a limited bandwidth WAN environment (frame relay, ISDN, etc.) to pinpoint offending traffic sources if certain links become saturated to the point where legitimate packets start getting dropped.
AstroFlow Bandwidth Management is a bandwidth management solution that features reports and many configuration options. With little or no knowledge of bandwidth management and packet shaping, it is possible to manage the traffic on your network, prioritize certain protocols such as POP3, SMTP, or databases, and guarantee that all mission-critical applications will have bandwidth available to them at all times, regardless of what other protocols are doing on your network.
Linux Bandwidth Arbitrator allows beginning-to-advanced network administrators to control bandwidth. It is designed to be completely turn-key in its default configuration. You just plug it into your network trunk, and it self configures and immediately starts slowing "bandwidth hogs". It can be configured to target specific applications such as Kazaa, IMAP, and POP. It is compatible with the 2.4.25 kernel, ebtables, and brouter (bridging router). It also comes with denial of service protection.
ibmonitor is an interactive Linux console application which shows bandwidth consumed and total data transferred on all interfaces. It shows received, transmitted, and total bandwidth, calculates and displays the combined value of all interfaces; can display values in Kbits/sec(Kbps) and/or KBytes/sec(KBps), can show the maximum bandwidth consumed, can show average bandwidth consumption, and can interactively change its output display format.
Bandwidth Management Tools is a total bandwidth management solution for Linux and can be used for firewalling, traffic graphing, and shaping. It is not based on any currently-available bandwidth management software and supports packet queues, bursting, complex traffic flow hierarchies, flow groups, traffic logging, and a simple real-time monitoring front-end.
