Introducing ATM
Networking
As a technology, ATM represents a sharp departure from LAN
alternatives such as traditional Ethernets that typically rely on
shared transmission me di a. That is, with Ethernet, severa l nodes
often contend for the right to transmit over shared cable segments
that support only one transmission at a time. When a node
successfully captures the media, it transmits its message at the
maximum allowed spee d, complet e ly consuming the media.
However, even in the best of circumstances, it is not unusual for two
or more nodes to begin transmitting at the same time and interfere
with each othe rs transmiss ion. Ethernet’s design anticipates and
compensates for unpredictable trans miss ion co llision s that occur.
How ATM Works
In cont rast to ot he r method s, ATM isolates netwo rk no des by fo rc i ng
them to attach to ATM switches using dedicated connections. ATM
switches the n intercon nect and cooperate with e a ch other to form a
network and p rovide commun ication conne ctions. While an ATM
node has full use of its switch attachment link, nodes share the
capacity of the links connecting the swi t ches. Unlike Ethernet
networks, this sharing is largely in visible to the nodes. Because of
this and other considerations, A TM provides numerous advantages
and capabilities that are difficult or impossible to obtain with legacy
LAN approaches. Perhaps the most important ATM benefits are its
2-1
ANA-5910/5930/5940 User’s Guide
native wide area connectivity, scaleable bandwidth, and bandwidth
guarantees.
Figure 2-1. ATM Networking
Wide Ar ea C o nnectivity
International telephon e companies have standardized ATM to
support their domestic telephone voice traffic. As nations deploy
their i ndividual ATM networks, ATM’s standard de f inition makes it
easy to in te rconnect th e se various ATM networks into a coop e rative
integrated global network.
2-2
Introducing ATM Networking
Scaleable bandwidth
ATM defines how ATM end-stations, such as your PC or
workstation, connec t to ATM switches and how ATM switches
interconnect with each other. Because these various co nne ctions
consist of dedicate d links, their construction (metal wire or fiber
optic) and the transmission speed they support may vary from link
to link. When connections require higher speed, it is usually easy to
upgrade the connection without disrupting other network nodes
and switches, upgrading transmission bandwidth only where
necessary.
Bandwidth guarantees
Whenever one ATM node communicates with another, it uses a
virtual connection that disguises the fact that connections actually
traverse shared media. In this way, ATM networks make it appear
that conne ctions are dedicated. Only if the necessary bandwidth is
available along the entire r oute does the connection setup complete
successfully. AT M’ s guarant eed bandw id th allo ws conne c tions to
transport audio, video, an d i mag e data that is sensit ive to time
delays that occur when bandwidth is unpredictable as it is with
Ethernet.
To further improve transmission predictability, ATM networks
transmit small, 53 byte messages, called cells. A cell contains 48 data
bytes and a five-byte head er. Since ATM tr ansmission media only
transport only one cell at a time, the small message size allows
switches and nodes to transmit high priority cells with minimum
delay. If switches are transmitting lower priority cells when a high
priority cell arrives, higher priorit y cell transm ission quic kly
commences when the lower priority transmission completes.
Node Identification
ATM end stations (nodes such as workstations) each have a unique
connection to any ATM switch to whic h they connec t. The
connection point at the switch is called a switch port and the switch
is a local sw itc h for the node. A T M nodes each have a globally-unique
network address. Ther e are various address schemes but, in most
cases, n odes r eceiv e their assigne d networ k addre ss fr om the switch .
2-3
ANA-5910/5930/5940 User’s Guide
To communicate with anot her node , an initiat ing node must initiat e
a signaling r eq uest to the signali ng Virtual Channel Connection (VCC)
residing within the local switch.
Virtual Channel Connections (VCCs)
Virtual Channel Connections (VCCs) are either constr ucted manual l y
or constructed by both nodes and all interv e ning switches.
Manually constructed connec tions are called Permanent V irtual
Circuits (PVCs) and must be manually deconstructed. With Switched
Virtual Connections (SVCs), one node ini tiates the VCC s e tu p p rocess
which proceeds switch-by-switch until the desired node is reached.
ATM networks that provide SVCs are considered signaling
environments. Finally VCCs can be point-to-po int, allow ing one
transmitter and receiver for any cell, or multicast VCCs that allow
one node to transmit a cell that many nodes receive.
An initiating node sends a connect ion setup re quest to its switch via
a special signaling VCC. The signal ing VCC is an example of a
control VCC - a VCC that re mains constan tly active. The switch then
cooperates with other nodes to construct a virtual conn e ction that
provides the appropriate Quality of Service (QoS). Link by link, the
procedure r eserves t he bandwidth r equir ed by the connection. If the
connection setup is successful, the nodes communicate using the
VCC which is represented by a Virtual Channel Identi fier (VCI) and a
Virtual Path Identifier (VPI). Together, the VCI and VPI identify the
VCC for its duration, and communicating nodes reference the VPI/
VCI pair within each transmitted cell, permitting subsequent cell
switching activity. When the communicat ion process is complete,
one of the co mmunicating nodes initiates the SVC tear-down.
ATM SONET/SDH Support
SONET is an acronym for Synchr onous Optical Net work - the
contemporary technology many North American telephone
companies use to bundle and transport domestic voice data within
Synchron ous Transport Signal (STS) data frames SDH is an acr onym
for Synchronous Digital Hierarchy - the contemporary technology
many European telephone companies use to bundle and transport
domestic voice data Synchronous Transport Module (STM) data
frames. Thro ugh i nt ern ational standardi zation efforts, SONET and
SDH are essentially identical except that the smallest STM frame
(STM-1) i s three times larger than the smallest STS frame (STS-1).
2-4
Introducing ATM Networking
ATM uses SONET and SHD technology to reduce costs while
achieving high transmissio n rates. Es sen tially, ATM combines
multiple STS-1 frames into STS superframes (STS-Nc, where N
stands for some integer value) and li k ewise for STM-1 frames.
Transmitting 8,000 single STS-1 frames at telephone company in a
second, referr ed to a s STS -1 tr ansmi ssi on, produces a 51.84 Mbit /sec
transmission rate.
An STS-3C transmission transmits 8,000 STS-3c superfram es in a
second, each composed of three concatenated (combined) STS-1
frames. This produces a 155.52 Mbit/sec transmiss ion rate which is
conve n ti o n a lly roun de d to 155 M b its/sec. The STS-3 c transm i s sion
rate is identical to the STM-1 tr ansmission rat e . ATM supports, or
will eventually support the following:
■
STS-1: 51.84 Mbits/sec
■
STS-3c: 155.52 Mbits/sec
■
STS-12c: 622.08 Mbits/sec
■
STS-24c: 1244.16 Mbits/sec
■
STS-48c: 2488.32 Mbits/sec
■
STS-192c: 9953.28 Mbits/sec
Adaptec ATM products currently support the STS-3C/STM-1
transmission rate of 155.51 Mbits/sec.
25.6 Mbit/sec ATM
ATM also supports 25.6 Mbit transmission speeds. Adaptec
products pr ov iding this tran smission speed at tach t o switc hes which
can subs eque n tly transpor t the data at any ATM transmissi on speed
necessary to reach a nother switch or node.
Classical TCP/IP
A data communication protocol is a set of conventions that
communicating entities observe to achieve unambiguous data
exchange and the TCP/IP suite of p rotocols is the most commonly
used data communication protocol suite. TCP/IP has prevailed
because it is an extensible, effective data communication protocol
suite des igned from the ground up to integrate disparate networks
with het e rogeneous comp uters. Because of its interconnectivi ty
origins, TCP/IP is essential to the Internet, which itself consists of

Classical IP Operational Summary
Within workstations, a TCP/IP commun ication protocol stack
recei ves application data streams an d fragments the flows into
datagram s. These datagrams can be up to 64 Kbytes long, thou gh
they are usually much smaller to accommodate physical media
constraints. Within the stack, IP components prepend datagram
headers and deliver the datagram to MAC components, such as
Ethernet components, for transmissi on. Intermediate routers route
the IP datagrams to destinations, further fragmenting the datagrams
into smaller datagrams if necessary. When datagrams arrive,
perh a p s out of order, receiving host IP components reassemble the
datagram s a nd corresponding TCP components re construct the
original data stream before delivering the da ta to an applic atio n. IP
prov id e s a connectionless, datagram transmission and routing
conduit while TCP superimposes necessary guaranteed data
delivery considerations between applications using mechanisms
such as exponential back off and slow start up transmission rate
flow controls as well as message receipt acknowledgments.
Within popular implementations, IP receives and delivers data fr om
and to two widely available higher level layers, TCP and UDP. UDP
2-6
Introducing ATM Networking
stands for User Datagram Protocol. Both TCP and UDP have
associated processes and applications that produce the messages
and streams TCP and UDP receive and deliver. While TCP provides
a reliable data transport mechanism to host applications including
checksums, UDP provides applications-specific IP addresses but
only provides its applic ations access onl y to IP’s connection less,
unreliable de livery.
Classical IP over ATM
Within contemporary networks, host IP software and IP routers get
datagram s fr om net work sour ces t o ne twork des tinati ons . Within an
ATM network, the ATM adaptation layer inte rcepts and converts IP
datagrams to and from cells. This spans the message transmission
differences inherent within each commu nication design. However,
it does not address the behavorial differences between components
above this layer. For instance, unlike A TM, the legacy delivery
process does not itself guarantee reli able, in-order delivery.
Because TCP/IP applications were designed in LAN environments
that naturall y provided broadcast services that are unavailable with
native AT M, other differences also require consideration before ATM
can sea m l e s sly transp ort IP da ta g r ams. The s e m e ch a nisms reso lve
IP addresses to ATM network addresses and provide TCP/IP’s
Address Resolution Protoco l (ARP) support. Many of these
considerations are re solve d in the Internet Engineering Task Force
(IETF) Request For Comment 1577 (RF C 1577). This document
prov id e s p rotocols, collectively referred to as Classical IP over ATM,
that introduce the concept of a Logical IP Subnet (LIS) - a group of
ATM no des, LIS cl ients, that belong to the same IP subnet.
Within each LIS , a si ngle ATM ARP (ATMARP) re solves ATM
addresses for the LIS clients. As nodes becom e opera tio na l, they
contact their ATMARP server and provide ATM and IP address
information to the ATMARP server. The server maintains a table
containing this information and references it whene ver a LIS client
requests IP ARP address resolution. When a LIS client obtain s the
ATM addr ess of an other c li ent, it can esta blis h di r ect c ommun ica tion
with the other LIS client using a conventio nal ATM connection. To
ensure table accuracy and station mobility, the ATMARP server
periodically dis ca rds old ent ries .

LAN Emulation
Clearly, ATM’s connection-oriented approach for communication is
distinctly different from the broadcast-oriented approach traditional
LANs use. ATM LAN Em ula tion, an industry-standard facility all
Adaptec ATM adapters support, provides necessary mechanisms to
address this requirement.
LAN emulation allows ATM networks to provide all services
available within legacy LA N e nvi ronment s. With LAN emulation,
ATM networks use their facilities to mimic communic ation
establishment procedures occurring within broadcast-oriented
legacy LANs. Once communication is established, ATM uses
normal ATM connections to exchan ge messages , usually many ti mes
faste r than with legacy LANs. Emulated LANs may con sist entirely
of ATM e n d st ations , i nclude transpa rent bridges that connect exiting
LANs to ATM networks, or both.
ATM LAN Emulation facilities consist of
■
LAN Emulation Clients (LECs)
■
LAN Emulation Configuration Server (LECS)
■
LAN Emulation Server (LES)
■
Broadcast and Unknown Server (BUS)
The fol lowing sections describe these components.
LAN Emulation Clients (LECs)
A LEC is an internal control VCC within end stations. LECs
communicate with other LAN emu lation components and LECs to
establish and provide LAN Emulation services. A LEC wholly
comprises the interface between legacy applications and ATM
networks. Therefore it must support various interfaces such as
NDIS and ODI.
When co mmunica ting with ano ther LE C, Data Direct VCCs transport
the data. For outbound data frames, LECs convert the LAN MAC
addresses that legacy LAN applications use into ATM network
addres ses and pass th e typic ally lar ge appli cati on data fr ames to the
correct ATM layer (AAL5) for conversion into cells for transmission.
For inbound cells, LECs reverse the process.
2-8
Introducing ATM Networking
LAN Emulation Configuration Server (LECS)
A LECS usually resides within an A T M switch. When queried by a
LEC over a Control Direct VCC, a LECS indicates what LAN(s) a L EC
can participate in base d on inp ut from a networ k administrat or.
LECs use the LECS to obtain the network address of the LES. A
temporary VCC, that transports this information, is the Configuration
Direct VCC.
LAN Emulation Server (LES)
The LES maintains a table of all ATM nodes participating within a
LAN and can return appropriate values to querying nodes. The LES
usually resides within a node’s local switch and helps determine
node addresses.
To determi ne appropriate ATM addresses, a LEC main tains a table
of recently determined conversion values. When a value is not
within the table, a LEC contacts the LES using the LAN Emulation
Address Resolution Protoco l (LEARP).
If a target n ode is an ATM end-station, the LES returns its address
and the process is complete. Otherwise the node is connected to a
legacy LAN which attaches to the ATM network using a transparent
bridge. If the LES does not have the appropriate MAC conversion
information to resolve addresses, the LES transmits associated
LEARP messages to the LES in any known transparent bridge using
Control Distribute VCCs. If a transparent bridge LEC recognizes the
specified MAC address, it provides the address to the original
requesting LEC and provide s neces sa ry mes s age -pas si ng facilit ies.
Broadcast and Unknown Server (BUS)
Occasionally, applications sen d LECs messages intende d to be
broadca st to all LAN mem bers . In this instan ce, the LEC p asses the
message to the BUS using a multicast VCC. The BUS then tran smits
the message to each participating LAN node using a multicast using
A TM multicast facilities. Receiving LECs filter these messages using
the node address and pass survi ving messages to in te nded
recipients.
