Anleitung Zusammenfassung


Usually this will be a server owned by the ISP. Get this IP address from your ISP. This is the second choice for a DNS server. Get this IP address from your ISP. The Maximum Transmission Unit size may be changed if you want to optimize efficiency for uploading data through the WAN interface. The default setting (1400 bytes) should be suitable for most users. Some user may want to adjust the setting to optimize performance for wireless traffic or when low latency is desired (such as with Internet gaming). It is highly recommended that the user research how adjusting the MTU may affect network traffic for better or worse. Network Address Translation may be enabled or disabled with the pull- down menu. Keep in mind that disabling NAT allows on a single computer to be used for Internet access through the Router. NAT is enabled and disabled for the Router on all connections (i.e. Pvc0 – Pvc7) if your Router is set up for multiple virtual connections. Use this to universally enable or disable the Firewall and Filter features available in the Router. If you disable this you will not be able to configure settings in the Firewall Configuration window or the Filters window in the Advanced directory. ATM Traffic Shaping The ATM settings in the WAN Settings windows for the different connection types can be used to adjust QoS parameters for ADSL clients. This may not be available to all ADSL accounts. ATM Settings for WAN connection Additional ATM settings for PPPoE or PPPoA connections: ATM Parameters Service Category The ATM settings allow the user to adjust ATM Quality of Service (QoS) or traffic parameters to suit specific traffic requirements. For applications or circumstances where packet loss or packet delay is a concern, ATM QoS can be adjusted to minimize problems. For most accounts, it will not be necessary to change these settings. Altering QoS settings can adversely affect performance of some commonly used Internet applications. If you plan to change QoS or traffic parameters, contact your ISP or network services provider for information on what types of adjustment are available or possible for your account. Your ISP may not support the class of service you want to use. To adjust ATM QoS parameters, select one of the Service Categories listed here and type in the PCR value in the entry field below. For the VBR service category, an additional parameter (SCR) must also be defined. UBR – Unspecified Bit Rate, this is the default category used for general- purpose Internet traffic where normal levels of packet loss and delay are acceptable. For some applications or for multiple connection accounts, it may be desirable to specify the PCR. CBR – Constant Bit Rate, usually used in circumstances where very low packet loss and very low Cell Delay Variable (CDV) are desirable. PCR Description VBR – Variable Bit Rate, usually used when network traffic is characterized by bursts of packets at variable intervals, and some moderate packet loss and delay is acceptable. This category is typically used for audio and video applications such as teleconferencing. The network must support QoS Class 2 to use VBR. Peak Cell Rate – The PCR is inversely related to the time interval between ATM cells. It is specified for all three service categories (UBR, CBR and VBR) in Kbps. SCR CDVT MBS Sustainable Cell Rate – The SCR is defined for the VBR service category. This is the rate that can be sustained for “bursty”, on-off traffic sources. It is a function of Maximum Burst Size (MBS) and the time interval (between cells). Cell Delay Variation Tolerance – CDVT is a measure of the cell clumping phenomenon by which cells are delayed in the network and are clumped together and arrive at a system at a faster rate than negotiated. Increasing the CDVT creates greater bucket depth. Maximum Burst Size – The MBS is the maximum number of bytes that can be sent continuously from the source to the destination dropping any packets. Some ATM providers set the MBS and CDVT very low and adjust up if problems occur. ATM VC Settings ATM VC settings can be configured for all connection types in the WAN configuration window of the Home directory. ATM VC Settings in WAN Settings window The table below describes the ATM VC settings used to configure a PPPoE or PPPoA connection for an ADSL account. ATM VC Parameters PVC VPI VCI Virtual Circuit Description The Router supports using up to eight multiple virtual connections. This window allows the user to configure WAN settings for all the available connections (see instructions below on how to set up Multiple Virtual Connections). Use the PVC drop-down menu to select the connection (Pvc0 to Pvc7) you want to configure. Since most users will use only a single connection, the default setting Pvc0 can be used for any changes made to the WAN settings. The Virtual Path Identifier is used with the VCI to define a dedicated circuit on the ATM network portion of the connection to the Internet and WAN. Most users will no...
