Introduction

All ATMworks 350L adapters are single–slot and provide a high performance architecture using a custom Application

Specific Integrated Circuit (ASIC) chip. This chip implements the ATM Adaptation Layer 5 (AAL5) protocol to map protocol

Data Units (PDUs) into the information field of ATM cells and vice versa. The ATMworks 350L supports the following features:

❖ High performance 155.52 Mbps ATM connectivity

❖ AAL5 and raw ATM traffic support

❖ Per VC rate control

❖ Early packet discard

❖ Integrated segmentation and reassembly (SAR)

❖ High performance convergence sublayer support

❖ Extensive variable bit rate (VBR) capabilities

❖ SONET/SDH (STS-3c/STM-1) physical layer support

❖ Fiber optics and unshielded twisted pair support

❖ Operation and Maintenance (OAM) cell support

At the core of the hardware is a custom–designed segmentation and reassembly (SAR) ASIC. This ASIC enhances performance by providing a hardware solution for the more complex functions of the ATM protocol. Functions such as the SAR and the common part convergence sublayer

(CPCS) of AAL5 are implemented in the ASIC.

Each virtual connection (VC) can be configured as an AAL5 connection or can be configured to transmit and receive raw data traffic. Raw data traffic consists of user–defined cell formats, as opposed to those formatted by the ASIC to conform to the AAL5 layer.

The ASIC also includes a high performance Direct Memory

Access (DMA) engine and slave copy capabilities. By designing a DMA engine specific to the ATM environment,

Digital Equipment Corporation is providing the network with maximum throughput by avoiding some of the limitations of the I/O architecture (i.e., the host bus).


ATMworks 350L

LEDs

Unpacking and

Inspection

The port on each ATMworks 350L is equipped with an LED that indicates proper cable connection. This LED, marked with a “#”, is helpful when connecting cabling because it indicates when the cables have been hooked up correctly.

The LED is lit when a valid SONET/SDH format signal is being received; it remains unlit if connected to a non–SONET/SDH format signal.

Note:

The LED will be lit when the ATMworks 350L is in diagnostic loopback mode regardless of what is connected to it.

Each ATMworks 350L should arrive in good condition. Before unpacking the card and accessories, check for any obvious damage to the packaging and notify your carrier immediately upon receipt.

The following items are included with each ATMworks 350L:

❖ Media containing driver software and configuration files

❖ This ATMworks 350L installation and configuration manual

❖ Anti–static wrist strap

Inspecting the ATMworks 350L

1

Attach the provided wrist strap as shown in the figure on the wrist strap envelope.

2

Remove the ATMworks 350L card from the antistatic bag and check for any damage.

3

If there are any visible signs of damage, return the card to the antistatic bag and repackage it in the original shipping container.

4

If any item is missing or damaged, immediately contact a

Digital Authorized VAR or distributor, or Digital Customer

Service.

ATM Concepts

The ATMworks 350L driver software is easy to install, yet there are certain pieces of information you will need to enter during the procedure. This section aims to provide the background needed to help you make decisions about how to configure your ATMworks 350L.

Asynchronous Transfer Mode networking technology represents a completely different paradigm than that used in existing LANs today. The Ethernet, Token Ring, and FDDI networks that are in widespread use are designed to broadcast data to all nodes. These networks use TCP/IP and other protocols to transfer the data.

By contrast, ATM transfers data over specific Virtual

Channel Connections (VCCs) that are created between one node and the next. ATM networks also require switches to route the data from one VCC to another.

Permanent Virtual Channels (PVCs) can be created and removed manually by a network administrator. This takes quite a bit of time and coordination to create a channel between each of the nodes on the network through one or more switches. Switched Virtual Channels (SVCs) are created dynamically using signalling protocols. The end–stations and switches exchange signals to set up and take down the

SVCs as necessary. The Digital Equipment Corporation

ATMworks 350L software is designed to create dynamic SVCs for data transfer; PVCs are not currently supported.

Though the high–speed data transfer rates of ATM are in high demand, some users would like to see ATM operate like the Ethernet network with which they are already familiar. For this reason, the ATMworks 350L software provides a LAN Emulation Client (LEC) so that an end–station can be configured to operate like any other node on an Ethernet LAN. This and other concepts are described in the following sections.

ATMworks 350L

IP Addresses

In order for your ATMworks 350L to communicate with other devices using the TCP/IP protocol, it must be assigned an

IP address.

12

Introduction


Use of the

Subnet Mask

!

Your site may have been assigned a set of IP addresses by the Internet Authority Board (IAB). The IAB ensures that each site with Internet access has a unique set of IP addresses that it can assign to its network nodes. You may have a block of addresses that you can use, or a single Class

A or Class B address that you can “subnet” using a subnet mask (described in the next section).

CAUTION:

The IP addresses for your ATMworks 350L must be on a separate subnetwork from any Ethernet, Token Ring or

FDDI network you have currently configured at your site.

Along with the IP address, a “subnet mask” must be defined for the ATM network. The subnet mask (also called the IP netmask) is used to specify the part of an IP address that designates the network and the part that designates the nodes or hosts on the network.

The subnet mask is used by routers, bridges, and other devices on the network in routing packets. The network part of the IP address tells the device whether the destination for the packet is on its same network. Once the correct network for the packet is found, the host portion is used to determine the packet’s destination (or source).

Each non–zero bit in the subnet mask indicates that the corresponding bit of the IP address is part of the network designator. Each bit set to zero indicates that the corresponding bit of the IP address designates a network node.

In the example shown in Figure 1-1, the subnet mask is shown in dotted–decimal notation. The first three octets are set to “255” (all ones). The same subnet mask is shown in binary in Figure 1-2.


ATM Concepts

13

Figure 1-1

Relationship of

IP Address to Subnet Mask

This subnet mask provides addresses for up to 256 nodes on the 194.86.24

network. To have more networks and fewer nodes on each network, set some of the bits in the last octet of the subnet mask to 1. The bits set to 1 will designate networks.

Subnet Mask:

IP Address :

Network Node

255 .255

.255

.0

194 .86

.10

When this subnet mask is applied to an IP address, it indicates that the first three octets of the IP address identify the network. Likewise, the final octet of the subnet mask is zero, indicating that the last octet of the IP address identifies nodes on the network.

Figure 1-2

Defining a

Subnet using Subnet Mask

Here, only the last four bits of the last octet are used to number the nodes on the network. Using just the last four bits only allows 16 nodes per network. However, the first four bits of the octet allow the designation of 16 more subnetworks than were available before.

LAN Emulation through ATM

LAN Emulation enables Ethernet or Token Ring traffic to run over ATM media without modification of existing applications. The LAN Emulation function operates at the media access control (MAC) sublayer of the OSI model’s Data

Link Layer. LANE protocols are used instead of MAC layer protocols to provide a service interface for the network layer protocols, as shown in Figure 1-3.

Data sent across the ATM network is encapsulated into the appropriate LAN MAC packet format. Thus, the LANE protocols allow an ATM network operate like an Ethernet

LAN, only faster.

The driver software for the ATMworks 350L you have purchased allows your PC to be configured to operate as a

“client” on an emulated LAN. The client software interfaces the ATM network to the higher–level (network layer) protocols so that they continue to communicate as though on an

Ethernet LAN.

LAN Emulation Components

Each individual emulated LAN will consist of the following components:

❖ A set of LAN Emulation Clients (LECs)

❖ One LAN Emulation Service consisting of:

• one LE Configuration Server (LECS) (optional)

• one LE Server (LES)

• a Broadcast Unknown Server (BUS)

Introduction

The LAN Emulation Client

An LEC is part of an ATM end–station that provides a standard LAN service interface to any higher layer entity.

The LEC also performs data forwarding, address resolution, and other functions within a single ELAN. Each LEC subnet can only reside on one emulated LAN at a time.

Each LEC has its own ATM address and/or ELAN name that may be used by the LANE Server in assigning the LEC membership in an ELAN. The administrator can assign an

LEC to a particular ELAN using the ATMworks 350L’s software configuration tools.

LAN Emulation Configuration Server

The LECS controls the assignment of LANE Clients to ELANs by directing them to the LES that corresponds to the designated ELAN. There is only one LECS per administrative domain serving all ELANs in that domain. The LECS has a unique ATM address.

The LAN Emulation Server

The LES coordinates control of the emulated LAN. The LES provides a facility for registering and resolving MAC addresses and/or 802.5 route descriptors to ATM addresses.

The LEC can register MAC addresses with the LES and query the LES to resolve MAC addresses and/or route descriptors. The LES may either answer a query directly or forward the query to other LECs so they may respond.

There is only one LES per ELAN and it has a unique ATM address.

Broadcast Unknown Server

The BUS provides the same type of broadcast and multicast service that is found in shared media LANs such as

Ethernet. The BUS is basically a multicast server that forwards unknown destination traffic, broadcast traffic, and multicast traffic to all clients on a particular ELAN.

The LANE 1.0 specification defines only one BUS per ELAN.

The BUS also has a unique ATM address that is configured


in the LES to map it to the broadcast MAC address (all ones). Also, the LES and BUS may have the same address.

Now you are ready to execute the installation and configuration procedures described in the next chapter. If any problems occur or you have any questions, please contact a Digital Authorized VAR or distributor, or Digital

Customer Service.

Attaching

Cables to the

ATMworks 350L

Take care to protect optical connectors against dust and physical contact with all other objects. Never touch the ends of the cables.

All disconnected optical connectors must be covered with dust protecting caps. Do not remove these caps until immediately before mounting the ATMworks 350L in the chassis. (See Figure 2-2 below.)

Figure 2-2

Dust

Protecting Cap

When no optical cable is connected to the ATMworks

350L, the protective cap supplied with the card should be plugged in to protect the optical transceiver.

Dust Protecting

Cap

When connecting optical cables between the ATMworks

350L and the switch, care must be taken so that the transmitter cable of the switch is connected to the receiver connector on the ATMworks 350L. Likewise, the switch’s receiver cable must be connected to the transmitter connector on the ATMworks 350L. The LED on the card is lit when the ATMworks 350L is properly connected.

When using simplex (single) SC connectors, ensure that the transmitter connector from the switch is attached to the connector marked , and the receiver connector from the switch must be attached to the connector marked .

When using a duplex SC connector assembly, the connector can only be plugged in the correct way.

Note: Be careful not to twist or bend the optical cable to the

point where it may break the glass fiber inside the cable.

Figure 2-3 on page 26 provides relevant information about the RJ45 jack and connector.

Table 2-1 and Table 2-2 contain the technical specifications for the two types of ATMworks 350Ls discussed in this manual.

There is particular information that you will need to enter when configuring the port on the ATMworks 350L and when each LAN Emulation Client is added. Multiple LANE clients are added as “logical adapters”; that is, the same “Add

Adapter” procedure is used to add each subsequent client.

Configuring the

Port Interface

There are four configuration parameters that can be set for the ATMworks 350L. These parameters are not specific to a particular client (logical adapter), but to the “port” through which the clients communicate with the physical interface on the adapter. Hence, they are referred to as “port configuration” parameters.

Slot Number

This is the slot number instance assigned by the system when the ATMworks 350L was installed. If the adapter is moved to a different slot, you may need to modify this slot number.

UNI Version

The UNI version may be set to

3.0

(default) or

3.1

. The UNI version used by the ATMworks 350L must match the version used by the connected switch. Check the switch configuration to determine how to configure the adapter.

Cell Frame Type

Specifies the standard to be used by the physical layer interface. The ATMworks 350L is configured to use the

SONET

(synchronous optical network) standard by default, but may be configured for

SDH

(synchronous digital hierarchy), which is the international standard. If the adapter is being installed outside the U.S., check to see if it should be configured to use SDH.

Empty Cell Type

This parameter specifies whether

Idle

(default) or

Unassigned

cells are transmitted from the end station when no valid cells are being transmitted. Unassigned

30

Software Installation and Configuration


cells are added to the assigned cell stream (cells with a valid payload) to provide a continuous stream of cells.

The receiving station will extract and discard any unassigned or invalid (idle) cells. Therefore, both cell types should be handled the same way by a switch or other receiving end station on the network. However, you may want to check your switch manufacturer's documentation to see if it handles unassigned and idle cells differently and configure the adapter accordingly.

Note:

The ATMworks 350L design adheres to the ITU-TS specification that calls for Idle cells to be sent when no assigned cells are being sent.

Configuring the

LANE Clients

During the adapter software installation, there are a few questions to be answered with regards to LAN emulation.

These are listed below along with detailed explanations.

Using the ESI as the MAC Address

To configure the ATMworks 350L to run on an emulated

LAN, you must uniquely identify each LAN Emulation

Client (LEC) as a node on the network. In connection-oriented networks, a MAC address uniquely identifies each node. In an ATM network, an End Station

Identifier (ESI) uniquely identifies each endpoint in the network. Each ATM adapter is configured at the factory with an ESI that is resident in PROM on the adapter.

By default, the driver uses the adapter's ESI as the

Network Address of each LEC when registering with

NDIS. If multiple LECs are configured on one adapter, each of them will have the same Network Address.

Two LECs having the same Network Address usually does not present a problem because each client is on a separate

Emulated LAN (ELAN). However, if two or more of the

LECs will be on ELANs that are bridged together, this will present a conflict. In such a case, you would need to assign a unique Network Address to any clients that will be on bridged ELANs instead of using the default ESI.

During installation, you can specify a different Network

Address to be registered with NDIS instead of the


Configuration Parameters

31

adapter's ESI. The address of the LEC is stored in the

Configuration Registry database.

The Network Address must be entered in hexadecimal characters, in the following format:

XX-XX-XX-XX-XX-XX

Example:

00-20-EA-00-30-16

Bypassing the LECS

Some switches available today do not provide a LAN

Emulation Configuration Server. The LEC on the

ATMworks 350L can still be used, however, if you connect directly to a LAN Emulation Server. Each LEC can be configured to connect to either an LECS or an LES.

Using the “well-known” LECS Address

If you will be connecting the LEC to an LECS, you may want to set the LECS address to the “well-known” address.

This address is specified in the LANE Specification as:

47-0079:0000:0000:0000:0000:0000-00a0:3e00:0001-00

You may not want to use the well-known address because it starts with the prefix “47” and your switch may not support this prefix. Or, there may be more than one

LECS on your network and you need to specify the address of the particular LECS to connect with.

Setting an ELAN Name

The ATMworks 350L software allows the specification of a specific emulated LAN for the LEC to join. You can enter up to a 32–character name of an ELAN during the software installation.

The ELAN name is passed by the LEC to the LECS when the software is trying to configure an ELAN or an LECS is trying to join the given ELAN. However, specification of an

ELAN name will not guarantee that the LEC will be joined to the specified ELAN. The membership of an LEC in an

ELAN is decided by the LES.
