  • Page 5: Where To Install Netequalizer

    User Guide Where to Install NetEqualizer NetEqualizer can be installed on any link whose traffic you would like to shape. For maximum effectiveness, most users should install NetEqualizer between the network users and the Internet trunk. Traffic running between your network and the Internet is generally a constriction point in traffic flow where many users compete for this limited resource.

  • Page 14: Configuring Equalizing Parameters

    RATIO parameter refers to the network utilization on a percentage basis. RATIO can be set from 1 to 100. A value of 100 tells NetEqualizer not to have the default rules kick in until the trunk is 100 percent utilized; a value of 85 would have the rules kick in at 85 percent utilized.

  • Page 15: Setting Your Trunk Size

    (Bandwidth Down). NetEqualizer allows for different speeds for outbound and inbound links, as equalizing shapes bi-directionally. These parameters are set in bytes/per second, and are used by the NetEqualizer so it can react and take action when your trunk is nearing capacity.

  • Page 16: Parameters To Adjust Equalizing Sensitivity

    Penalty Unit (PENALTY_UNIT) (units are 100ths of seconds, Default = 2) PENALTY_UNIT is the unit of time that NetEqualizer will start with when delaying a packet of Internet data. It iteratively increases penalties by this value should a “hog” not respond to the initial penalty.
  • Page 17 ANCIENT (units are seconds, Default = 20) Ancient is no longer visible on the NetEqualizer GUI. The Ancient parameter is how long to keep a penalty in effect, in seconds. The preset value for ANCIENT from our factory- delivered NetEqualizer is designed to handle any size network and need not be changed.

    (slowed down). When NetEqualizer sets a penalty on a connection, it assigns a “delay” buffer to this connection to slow it down. NetEqualizer reserves a finite number of “delay” buffers when it powers up.

  • Page 20: Controlling P2P Traffic

    NetEqualizer enables you to limit the amount of bandwidth a specific IP address or set of IP addresses can use. There are two ways to configure this in the NetEqualizer, to best meet your needs.
  • Page 21 Make sure when setting up your Connection Limits that you do not create an overlap between subnetted Connection Limits (/24, /16, etc.). The NetEqualizer does not support an overlap between subnetted Connection Limits. For example, this is NOT allowed, as the subnet ranges overlap.

  • Page 22: Dynamic Hogmin: Creating Smart Connection Limits

    Limit as high as sixty (60) to facilitate online game playing. Note: When you first set up a Connection Limit for an IP address, NetEqualizer will not drop existing connections over the limit. We wait until the overages die off or finish, but in the meantime the IP address cannot open any more connections.
  • Page 23 IP addresses that you wish to smart connection limit (Dynamic Hogmin will apply), formatted as follows: For an individual IP address: 10.0.10.106/32 For a subnet: 10.99.1.1/16 APconnections, Inc. // 303.997.1300 // www.netequalizer.com Page 23 of 97 All rights reserved Copyright © 2013 APconnections, Inc. rev. 20131202...
  • Page 24 1. Dynamic Hogmin 2. Dynamic Hogmin Connections Dynamic Hogmin When turned on, NetEqualizer will allocate bandwidth based on the number of connections a given IP is using. To set Dynamic Hogmin, click on the drop down box and select ON.

  • Page 25: Setting Bandwidth Limits

    Note: You cannot assign a Bandwidth Limiting Rule to an IP address that physically sits on the WAN side of the NetEqualizer. For example, you cannot put a hard limit on an Internet site such as yahoo.com. If you do, the Hard Limit will be ignored. This makes sense, as the NetEqualizer is intended to manage your internal (LAN) IP addresses.

  • Page 26: Adding Bursting To Hard Limits

    In order to make bursting a “special” feature, it obviously can’t be on all the time. For this reason, by default the NetEqualizer will force a user to wait 80 seconds before they can burst again.
  • Page 27 80 seconds after its last burst duration completes before bursting again. The second parameter, BURST DURATION, is the time an IP will be allowed to burst (in seconds) before being relegated back to its base Hard Limit.

  • Page 28: Setting Up Bandwidth Pools

    NetEqualizer to accommodate cases where bandwidth is advertised and sold as "you are one of n customers sharing x bandwidth". Think of a pool as a "virtual NetEqualizer". You can group users into logical trunks by IP address and apply equalizing technology to each logical group (bandwidth pool).

  • Page 30: Setting Hard Limits By Vlan

    Bandwidth Pools can number from 1 to 300; up to 300 different bandwidth pools per NetEqualizer (< 4.5 the number is limited to 40). Note: If you plan to set up a large number of subnet-ranged Pools (>=32 subnet ranges), you will need to set several tuning parameters.

    VLAN. For example, if you set the download limit on a specific VLAN to 192,000 bytes per second (T1) and the VLAN usage level reaches 85 percent, the NetEqualizer will begin to penalize any connection exceeding the value of HOGMIN within the VLAN.
  • Page 32 Access Points. Most of the time you would only see the address of the Router or Access Point, which would not enable you to shape down to the user level on your network. APconnections, Inc. // 303.997.1300 // www.netequalizer.com Page 32 of 97 All rights reserved Copyright ©...

  • Page 33: Consider Setting Bandwidth Priority

    Equalizing Rules. However, some organizations need to setup Bandwidth Priority Rules for specific traffic types. There are two types of priority that you can set up on the NetEqualizer: 1) traffic with priority over equalizing, and traffic hidden from equalizing.

  • Page 34: Dynamically Allocating Priority Traffic

    Note that if you set too much priority traffic, you will push all your remaining traffic into a very small window. Factory delivered, NetEqualizer defaults are set to perform congestion control on your trunk when it becomes 85 percent full. In most cases, important business applications, such as VoIP, citrix, blackboards, web browsing, and e-mail will receive preferential treatment, and therefore there is no need to assign priority.
