Methods used for traffic shaping?
Shaping by application: Administrators can configure a traffic shaperby categorizing specific types of network traffic and assigning that category a bandwidth limit. For example, traffic can be categorized usingFTP. The rule can specify that no more than 4Mbps be dedicated for FTP traffic. This same principle can apply to Telnet sessions, streaming audio, or any other application coming through the network.
. Shaping network traffic per user: Every network has users who use more bandwidth than others. Some of this might be work-related, but more often than not, it is personal use. In such a case, you might need to establish traffic shaping on a per-user basis. Traffic shapers allow administrators to delegate a certain bandwidth to a user. For instance, Bob from accounting is allowed no more than 256Kbps. This doesn’t limit what the user can access, just the speed at which that content can be accessed.
. Priority shaping: One important consideration when looking at trafficshaping is determining which traffic is mission-critical and which is lessso. In addition to setting hard or burstable traffic limits on a per-applicationor per-user basis, traffic shaping devices can also be used to definethe relative importance, or priority, of different types of traffic. For example, in an academic network where teaching and research are most important, recreational uses of the network (such as network games orpeer-to-peer file-sharing application traffic) can be allowed bandwidth only when higher-priority applications don’t need it.
