Internal host/gateway interface

Applications and features

Internal host/gateway interface

There is a special host/gateway logical IP interface within M1112 called VBRIDGE. This interface has a specific purpose in M1112. In applications where some ATM virtual channel connections are used for bridging IP traffic and some other ATM virtual channel connections are used for routing IP traffic, the VBRIDGE interface must be used instead of LAN IP address. Alternatively, this interface is used in bridge only application when the IP address is required for remote management purposes.

Data VCC operation

M1112 supports the following encapsulations in each ATM data virtual channel individually:

DRFC2684 LLC encapsulation for bridged IP (ETH-LLC)

DRFC2684 LLC encapsulation for routed IP (IP-LLC)

DRFC2364 Virtual circuit multiplexed PPP over AAL5 (PPP-VC)

DRFC2364 Virtual circuit multiplexed PPP over AAL5 used to tunnel LAN/VBRIDGE PPTP packets (TUNNELED-PPP-VC)

If an IP address is given to a virtual channel interface and bridging is enabled at that interface, then IP data at that interface is routed and all other protocols are bridged. The only encapsulation which allows both bridging and routing simultaneously is ETH-LLC. For example, it is possible to route ETH-LLC encapsulated packets and at the same time bridge, for example, PPPoE packets (PPPoE packets are transported directly over Ethernet frame, not within IP packets).

2.2.2Routing

Routing is based on routing entries in a routing table. Static routes are added via the management interface and dynamic routing is done using RIP and RIPv2. Routing is done between the Ethernet 10Base-T interface and the virtual channel connection (VCC) of the ATM/ADSL interface. M1112 supports up to 8 simultaneous VCCs.

M1112 supports IGMP (Internet Group Management Protocol) proxy receive function for IP multicast applications.

2.2.3Bridging

Bridging is supported to provide full protocol transparency. Bridging can be used simultaneously with IP routing. M1112 works as a

M1112 ADSL technology is based on Discrete Multitone DMT modulation allowing a maximum of 8 Mbit/s data transmission from the network and 800 kbit/s towards the network. However, these figures illustrate the maximum performance of the technology and are subjected to the physical line conditions and the distance from you to the central office. M1112 is capable of adapting to the physical line conditions and guarantees the maximum transmission rate possible on the particular line. M1112 adapts its speed to the line conditions in steps of 32 kbit/s. In addition to these physical limitations affecting your data throughput, your Internet Service Provider ISP may limit your access according to their service provisioning policy and based on your
