P-335 Plus User's Guide CHAPTER 12 Bandwidth Management This chapter contains information about configuring bandwidth management, editing rules and viewing the ZyXEL Device's bandwidth management logs. 12.1 Bandwidth Management Overview ZyXEL's Bandwidth Management allows you to specify bandwidth management rules based on an application and/or subnet. You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to different bandwidth rules. The ZyXEL Device applies bandwidth management to traffic that it forwards out through an interface. The ZyXEL Device does not control the bandwidth of traffic that comes into an interface. Bandwidth management applies to all traffic flowing out of the router, regardless of the traffic's source. Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the ZyXEL Device and be managed by bandwidth management. • The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, WAN to WAN / ZyXEL Device) must be less than or equal to the Upstream Bandwidth that you configure in the Bandwidth Management Advanced screen. • The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, LAN to LAN / ZyXEL Device) must be less than or equal to 100,000 kbps (you cannot configure the bandwidth budget for the LAN port). 12.2 Application-based Bandwidth Management You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, Email and Video for example). 12.3 Subnet-based Bandwidth Management You can create bandwidth classes based on subnets.
