`RALEIGH, N.C. — IBM will
`strengthen its peer-to-peer net-

`with the rollout of software prod-

`equipment into the APPN era.
`The newiproducts include an
`automatic configuration facility

`package that

`PC price war isn’t all good
`news for network vendors

`Network
`have had good reason to be bull-
`ish in the personal computer
`price war, given that users are
`hooking most of their new low-
`cost PCs into networks.
`But the war may windup cost-
`ing net vendors in the long run.
`As PC prices plummet,
`the
`costs of associated network prod
`ucts, such as local-area network
`adapter cards and PC-to—main-
`frame gateways, are looking high
`in comparison. It seems likely
`that vendors will have to trim
`prices and profit margins due to
`pressure from customers.
`“There are good and bad
`things for network vendors in the
`
`PC price war.“ said Todd Dagres.
`director of data communications
`research at The Yankee Group, a
`market research firm in Boston.
`"Lower prices are making it
`more attractive for users
`to
`downsize from mainframes to

`said. “On the other hand, users
`are asking why a network connec—
`tion is now a bigger percentage of
`the cost of a workstation than it
`used to be, which will result in
`price pressure on the vendors."

`
`Protocol faces deficienciesIn large router-based
`intemets; consortium formed to‘address problems.
`By Maureen Molloy
`Senior Writer
`
`For many users, trying to run
`AppleTalk across an enterprise-
`wide intemet is like trying to fit a
`square peg into a round hole.
`Apple Computer, Inc‘s rout-
`ing protocol has long been criti-
`cized for its inordinate use of
`bandwidth, inefficient path selec-
`tion and poor congestion man—
`agement capabilities when rout-
`ing across widearea net links.
`Mike Bailey, a systems inte-
`grator at Lockheed Missiles and
`Space Company, Inc.
`in Sunny-
`vale, Calif.,
`is one such critic.
`When he began designing an Ap-
`pleTalk net for the aerospace gi-
`ant, Bailey was told to isolate the
`AppleTalk nodes to a
`single
`Ethernet segment and keep Ap-
`pleTalk traffic off the company‘s
`multiprotocol backbone for fear
`it would bog down net perfor-
`mance.
`
`working." he said, “No onewants
`to hear about AppleTalk because
`it causes too many problems and
`complicates the network.“ Al—
`though the protocol works well in
`small departmental work groups.
`Bailey said it breaks down when
`large numbers of Macintosh work
`groups are linked together.
`But vendors are now taking
`strides to resolve the nagging is-
`sues users encounter with Apple-
`Talk.
`'
`For instance. a consortium of
`vendors whose roster includes
`Apple, Cisco Systems. Inc. No-
`vell. Inc., 5Com Corp. and Well-
`fleet Communications. Inc. will
`begin working this month to
`make AppleTaIk more sturdy
`("Consortium to shape fate of
`AppleTalk," NW, Nov. 16).
`One of the main deficiencies
`of AppleTalk today is the Routing
`Table Maintenance
`Protocol
`(RTMP). a transport-layer prow- _
`col used to create and maintain

`Net managers can access that in-

`Because the net manager can
`configure the ILAN router to cap-
`ture all traffic from the local—area
`network on which it resides, Net~
`work Inventory allows net man-
`agers to obtain management in-
`formation down to the endnode

`Once the routers have been

`managers can click on an icon for
`an [LAN router and find a Wide
`range of information, including
`the identity of computers added
`to the LAN or those moved from
`one LAN to another, as well as

`CrossComm Corp. has added a
`new inventory feature to its net-

`to use the company‘s ILAN Uni-

`mation on remote network de-
`vices.
`The new capability, dubbed
`Network Inventory,
`is possible
`because of enhancements in Ver-

`
`fiber-optic interface module
`for its Series 7700 Intelligent

`With RTMP, routers swap their entire

`prtgipting frequent logjams on wide-area
`Apple has developed a protocol to sup-
`plant RTMP, called the Apple Update Rout-
`ing Protocol (AURP), thatwill enable rout-
`ers, to route AppleTalk over WANs using
`Transmission Control Protocol/Internet
`Protocol encapsulation. The AppleTalk
`packet is cloaked in a TCP/IP envelope,
`which is discarded 'when it reaches the
`router. The AppleTalk identifier is then
`used on the AppleTalk net at the other end.
`AURP'S broadcasts are update-based
`only, thereby letting two autonomous Ap-
`pleTalk domains be linked without the ex~
`cessive overhead associated with RTMR In‘
`addition. the AURP updates occur every 30
`seconds instead of R'I'MP's IO~second in-
`terval, further trimming traffic congestion
`on the WAN.
`Since many users are looking to reduce
`the number of protocols they natively
`route across the WAN. “Tapping AppleTalk
`in TCP/IP would also help eliminate some
`of the intensive upkeep associated with a
`multiprotocol network.
`Another specification jointly developed
`by the intemet vendors and now embraced
`by Apple mirrors AL‘RP in that it also en-
`capsulates AppleTalk in TCP/IP and
`broadcasts routing table updates less fre-
`quently. The so-called Dr. Pepper specifi~

`The forum will also investigate the pos-
`sibility of developing a link state protocol
`like the Open Shortest Path First (OSPF)
`or the Intermediate System to Intermedi-
`ate System (IS-IS) protocols for Apple'l‘alk
`to provide better distribution of traffic and
`better reponses to failed links.
`AERP and Dr. Pepper are distance vec-
`tor protocols that not only transmit fre-
`quent routing updates. but also select a
`
`routing path based solely on the smallest
`hop count'between the source and destina-
`tion node.
`AppleTalk routers based on a link-state
`protocol such as OSPF or lS-IS. on the oth-
`er hand. would not send one another en-
`tire routing tables. but rather information
`about which links each router has to adja-
