Unicast
Unicast is the term used to describe communication where a piece of information is sent from one point to another point. In this case there is just one sender, and one receiver. Unicast transmission, in which a packet is sent from a single source to a specified destination, is still the predominant form of transmission on LANs and within the Internet. All LANs (e.g. Ethernet) and IP networks support the unicast transfer mode, and most users are familiar with the standard unicast applications (e.g. http, smtp, ftp and telnet) which employ the TCP transport protocol.

If If you are looking to control the amount of bandwidth for a particular host using a Cisco ASA Security Appliance, you’ve come to the right place. When I was first asked to look into this capability on the ASA I knew that I could perform some sort of Quality of Service (QOS). In fact, all of the documentation that I came across either on Cisco’s website or from third party integrators have detailed information on controlling quality for VoIP, traffic shaping, and how to do those things across a VPN tunnel. While the information on these great features of the ASA is helpful, finding articles on limiting bandwidth to a particular IP address was more difficult to track down. In fact, it took a TAC case and several hours of reading papers on the above services until I was able to figure out how to police bandwidth using my ASA. In the example below I am throttling bandwidth to 1Mb for the host 1.1.1.1:
