BWPing
BWPing is a tool to measure bandwidth and response times between two hosts using Internet Control Message Protocol echo request/echo reply mechanism. It does not require any special software on the remote host. The only requirement is the ability to respond on Internet [Control Message Protocol|ICMP] echo request messages. BWPing supports both IPv4 and IPv6 networks.
Command syntax
bwping -b kbps -s pkt_size -v volume target
bwping6 -b kbps -s pkt_size -v volume target
Available options are:
- -4 - Forces IPv4 mode. Default mode of operation is IPv4 for bwping and IPv6 for bwping6 otherwise.
- -6 - Forces IPv6 mode. Default mode of operation is IPv4 for bwping and IPv6 for bwping6 otherwise.
- -B - Sets the source address of outgoing ip packets. By default the address of the outgoing interface will be used.
- -I - Sets the Identifier value of outgoing ICMP Echo Request packets. If zero, the value of the lower 16 bits of the process ID will be used.
- -T - Sets the TOS value of outgoing IPv4 packets or IPv6 Traffic Class value of outgoing IPv6 packets. Default value is zero.
- -r - Sets the interval time in seconds between periodic bandwidth, RTT, and loss reports. If zero, there will be no periodic reports.
- -u - Sets the size of the socket send/receive buffer in bytes. If zero, the system default will be used. Tune this parameter if the speed measurement results are unexpectedly low or packet loss occurs.
- -b - Sets the transfer speed in kilobits per second.
- -s - Sets the size of ICMP packet in bytes.
- -v - Sets the volume to transfer in bytes.
