Chapter 17 Bandwidth Management NBG420N User’s Guide 201 17.6 Predefined Bandwidth Management Services The following is a description of the services that you can select and to which you can apply media bandwidth management using the wizard screens. 17.6.1 Services and Port Numbers SeeAppendix F on page 321 for commonly used services and port numbers. Mid Typically used for “excellent effort” or better than best effort and would include important business traffic that can tolerate some delay. LowThis is typically used for non-critical “background” traffic such as bulk transfers that are allowed but that should not affect other applications and users. Table 72 Bandwidth Management Priorities PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED. Table 73 Media Bandwidth Management Setup: Services SERVICEDESCRIPTION Xbox LiveThis is Microsoft’s online gaming service that lets you play multiplayer Xbox games on the Internet via broadband technology. Xbox Live uses port 3074. VoIP (SIP)Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is transported primarily over UDP but can also be transported over TCP, using the default port number 5060. FTPFile Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail. FTP uses port number 21. E-MailElectronic mail consists of messages sent through a computer network to specific groups or individuals. Here are some default ports for e-mail: POP3 - port 110 IMAP - port 143 SMTP - port 25 HTTP - port 80 BitTorrentBitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software and media files using ports 6881 to 6889. BitTorrent requires you to search for a file with a searching engine yourself. It distributes files by corporation and trading, that is, the client downloads the file in small pieces and share the pieces with other peers to get other half of the file. MSN WebcamMSN messenger allows you to chat online and send instant messages. If you use MSN messenger and also have a webcam, you can send your image/photo in real-time along with messages WWWThe World Wide Web (WWW) is an Internet system to distribute graphical, hyper- linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser. Chapter 17 Bandwidth Management NBG420N User’s Guide 202 17.7 Default Bandwidth Management Classes and Priorities If you enable bandwidth management but do not configure a rule for critical traffic like VoIP, the voice traffic may then get delayed due to insufficient bandwidth. With the automatic traffic classifier feature activated, the NBG420N automatically assigns a default bandwidth management class and priority to traffic that does not match any of the user-defined rules. The traffic is classified based on the traffic type. Real-time traffic always gets higher priority over other traffic. The following table shows you the priorities between the three default classes (AutoClass_H, AutoClass_M and Default Class) and user-defined rules. 6 is the highest priority. 17.8 Bandwidth Management General Configuration ClickManagement > Bandwidth MGMT to open the bandwidth management General screen.
