`
`executable
`
`module on the remote node.
`
`Two approaches
`
`have
`
`been
`
`successfully achieved
`
`within this thesis.
`
`One
`
`is
`
`to
`
`develop
`
`the executable
`
`module on the PDP-11/44 computer
`
`and
`
`then
`
`download
`
`the
`
`module through the Ethernet
`
`LAN to the LS1-11/23 computer
`
`and to
`
`execute
`
`the module
`
`on
`
`the LS1-11/23 computer.
`
`Another one is to download the executable module from the
`
`Intel Series IV Microcomputer Development
`
`System through
`
`the Fthernet LAN to the iSBC86/5% single
`
`board computer
`
`and to execute the module on the single board computer.
`
`Potential
`
`applioaiton areas
`
`of
`
`this
`
`technique
`
`are like Automatic Test Equipment, Laboratory Automation,
`
`and Factory Automation.

`CHAPTER

`
`INTRODUCTION
`
`The development of electronic
`
`computers and the
`
`experience gained with
`
`their
`
`applications in economic,
`
`scientific, industrial, and technical areas have revealed
`
`that it is both necessary and efficient to employ remote
`
`data access (over data transmission channels) and remote
`
`output of the results.
`
`The experience upon geographically
`
`widely distributed computer systems shows the necessity of
`
`switching from centralized computer
`
`systems to networks
`
`that make all programs, data and ether resources available
`
`to any node on the network regardless geographic location
`
`of the resources and the users.
`
`Over
`
`the
`
`last
`
`decade,
`
`there
`
`has
`
`been Vigorous
`
`development on
`
`computer
`
`networks
`
`for data
`
`bases
`
`and
`
`information retrieval services.
`
`In any computer network
`
`there exists a collection of machines intended for running
`
`user
`
`programs.
`
`Normally,
`
`a
`
`computer
`
`on
`
`the
`
`network
`
`contains a resident bootstrap which will
`
`load a permanent
`
`program from mass storage devices onto its memory.
`
`The
`
`permanent
`
`'program may
`
`have
`
`the form of a monitor,
`
`an
`
`interpreter or
`
`an operating system through which
`
`local

`
`
`
`user programs can be processed.
`
`Let
`
`us
`
`define
`
`such a
`
`computer, which has a
`
`terminal, I/0 devices. mass storage
`
`devices and/or intelligence with it. on the network as a
`
`"SMART Noon"
`
`(See Figure 1.1), for example, VAX,
`
`IBM/PC,
`
`IBM/4341,
`
`INTEL so/33o,
`
`INTEL so/sen, etc.
`
`A station, which has data acquisition and
`
`data
`
`display equipment, on the network may have no mass storage
`
`device with it so that human resources can not develop
`
`executable program on it.
`
`Let us also define
`
`such
`
`a
`
`station on the network as "REMOTE NODE", for example,
`
`iSBC86/3%,
`
`iSEC286/10, Micro VAX, etc.
`
`This paper
`
`investigates the technique to download
`
`a
`
`task (or process) from a
`
`SMART
`
`MODE to
`
`a particular
`
`REMOTE NODE, which has the same type of CPU as the SMART
`
`NODE
`
`host
`
`CPU, Tanenbum (1982),
`
`and
`
`to
`
`process
`
`the
`
`downloaded task (or process) at
`
`the REMOTE NODE by using
`
`the network bootstrap.
`
`Here we define such
`
`a
`
`task
`
`or
`
`process
`
`to
`
`be
`
`downloaded and processed at
`
`the
`
`REMOTE
`
`NODE as
`
`REMOTE
`
`pnocrss" (See Figure 1.2).
`
`The task running on the REMOTE NODE for receiving
`
`and executing the
`
`REMOTE
`
`PROCESS is defined as
`
`"REMOTE
`
`BOOTSTRAP".
`
`The task that
`
`runs on
`
`the
`
`SMART worn
`
`for
`
`downloading REMOTE PROCESS is denoted by "BOOT LOALER".
`
`The later part of this Chapter willintroduce
`
`existing commercially available LANs (Iocal Area Networks)

`
`
`
`1.1 Approach
`
`The LANs
`
`(Local Area Networks) can be classified
`
`into two types, Baseband and Broadband.
`
`The Baseband type
`
`LAN uses a single digital
`
`frenquency as the transmission
`
`carrier with a data rate of 10-2% mbps depending on the
`
`type of transciever used, while the Broadband type uses
`
`an RF (Radio Frequency) signal as the transmission carrier
`
`with multiple RF channels in the 566-400 MHz bandwidth and
`
`a 2-5 mbps data rate on each channel.
`
`The goal of the
`
`topology design is to achieve a
`
`specific performance at a minimal
`
`cost.
`
`As
`
`shown
`
`in
`
`Figure 1.5,
`
`two
`
`topologies are practically applied for
`
`LANs' installation. with the Hierarchial Tree topology.
`
`the higher
`
`PEs
`
`perform control
`
`functions while lower
`
`PEs perform specialized functions.
`
`PE failures higher up
`
`in the tree become very serious tc the LAN. with a Global
`
`Bus
`
`topology, each PE is multidropped to the global bus.
`
`and failure of one PE does not affect LAN’s performance.
`
`Figure 1.4 shows the typical LAN’s configuration.
`
`In recent years, a wide variety of
`
`LANs
`
`from
`
`different vendors running under different environments
`
`have been developed.
`
`These include systems such as
`
`Omninet
`
`(Corvus Systems), Net/One
`
`(Ungermann-Bass),
`
`Cluster/One (Nestar Systems), Ringnet
`
`(Prime Computers),
`
`wangnet
`
`(Wang Laboraries). Domain (Appollo Computers).

`
`LOCAL AREA NETWORK SYSTEM STRUCTURE
`
`A heterogeneous computer local area network can
`
`consists of a wide variety of machines which process
`
`different
`
`tasks
`
`under particular
`
`environments
`
`by
`
`employing different processors.
`
`In order to reduce
`
`design complexity. modern computer
`
`IANS are designed in
`
`a highly structured way. Most Laws are organized using
`
`a modular layering concept which provides an integrated
`
`systems approach by decomposing large complex tasks into
`
`smaller, more managable, modular layers.
`
`Each
`
`layer
`
`performs a set of well-defined functions,
`
`and
`
`has
`
`a
`
`we1l—defined
`
`set of
`
`higher
`
`and lowerlayer interfaces.
`
`Therefore.
`
`to one end of
`
`the communication channel, each
`
`layer except
`
`the lowest
`
`layer performs a peer protocol
`
`operation with the protocol corresponding layer on the
`
`other end.
`
`As
`
`a
`
`first
`
`step
`
`toward
`
`the
`
`international
`
`standardization of
`
`the
`
`various
`
`network protocols,
`
`ISO (International Standard Organization) has proposed the
`
`seven-layer Reference Model of Open System Interconnection
`
`(051). Zimmermann (1982).

`
`Refering to the OSI Reference Model
`
`in Figure
`
`2.1, when transmitting,
`
`the user process
`
`(Application
`
`Layer) passes information to
`
`layer 5.
`
`then
`
`each
`
`layer
`
`encapsulates the information by appending its frame header
`
`to the information and passes the encapsulted frame to the
`
`next
`
`lower layer all the way down to the Physical Layer.
`
`when receiving,
`
`the Physical
`
`layer receives the packet
`
`from the network,
`
`then each layer decapsultes the packet
`
`by peeling off its frame
`
`header
`
`from the
`
`packet
`
`and
`
`passes
`
`the decapsulted
`
`frame
`
`to the next higher layer
`
`all
`
`the way up to the Application Layer
`
`(User Process)
`
`(See Figure 2.2).
`
`The OSI Reference Model will be used
`
`as the basis for discussion of protocols in the Ethernet
`
`examples.
`
`2.1 Logical Structure
`
`As
`
`shown in Figure 2.3,
`
`the LAN vendors supply
`
`the implementation of
`
`lower layers of
`
`the 031 Reference
`
`Model so that
`
`the
`
`LAN users
`
`can
`
`develop
`
`their
`
`ywn
`
`software for implementing higher layers.
`
`The Ethernet Data Link Layer and Physical Layer
`
`Specifications. specified by Xerox and jointly supP0Pt€d
`
`by Dec,
`

`
`and Xerox,
`
`is logically structured and
`
`complies with the Data link Layer and Physical Layer of
`
`the OSI Reference Model
`
`(See Figure 2.4).

`
`2.1.1 Ethernet
`
`The Ethernet Data Link Layer supports the two main
`
`functions generally associated with a data link control
`
`procedure as follows:
`
`1.
`
`Iata Encapsulation/Decapsulation:
`
`- Framing
`
`(variable
`
`frame
`
`size
`
`boundary
`
`delimitation)
`
`— Addressing (handling of aource and destination
`
`addresses)
`
`- Error Detection (detection of physical channel
`
`transmission errors)
`
`2. Link Management:
`
`- Channel Allocation (collision avoidance)
`
`- Contention Resolution
`
`(CSMA/CD collision
`
`handling scheme)
`
`The Ethernet
`
`Physical Layer
`
`is
`
`capable
`
`of
`
`exchanging
`
`data
`
`over
`
`a
`
`coaxial
`
`cable,
`
`enabling
`
`ccrmunication between the respective stations at
`
`the Data
`
`Link Layer and higher layers of the CS1 Reference Model.
`
`It supports the two main functions generally associated
`
`with physical channel control:
`
`1. Data Encoding:
`
`- Preamble Generation/Removal (for synchronization)
`
`- Bit Encoding/Decoding (between binary and phase-
`
`encoded form)

`
`PMC Exhibit 2088
`Apple v. PMC
`IPR2016-00755
`Page 23
`
`
`

`
`2. Channel Access:
`
`- Bit Transmission/Reception (of encoded data)
`
`— Carrier Sense (indicating traffic on the channel)
`
`- Collision Detection (indicating contention on the
`
`channel)
`
`The Physical Layer
`
`transmits the messages onto the
`
`coaxial cable in the typical
`
`frame format illustrated in
`
`Figure 2.5.
`
`2.1.2 NI121Z, NI2@l£, and iSFC55Z
`
`The
`
`NI1@13 and
`
`NI2@1@ Ethernet Communications
`
`Controllers shown in Figure 2.6,
`
`implemented by Interlan
`
`Corporation, provide two layers of the OSI Model,
`
`the
`
`Physical
`
`layer and the Data Link layer, NI1@1Z (1982),
`
`NI2E1Z (1932).
`
`In addition to the functions provided by
`
`the Nllfllz and NI2@1h Controllers,
`
`the 1536553 Ethernet
`
`Communications Controller shown in Figure 2.7 performs
`
`part, but not all. of the Network Layer protocol
`
`(next
`
`higher layer to the Data Link Layer of
`
`the OSI Reference
`
`Model). There is a MIP (Mu1tibus Interprocessor Protocol)
`
`facility, residing on the iSBC55Z Controller Board,
`
`through which the host computer talks to the Ethernet
`
`LAN Channel by exchanging messages within the shared
`
`memory on c Multi-bus System Bus. MIP actually performs
`
`Network Management issues.

`
`2.1.3 REMOTE BOOTSTRAT and BOOT LOADER
`
`According to the OSI Reference Model.
`
`the
`
`Presentation Layer performs functions that
`
`are
`
`requested
`
`sufficiently often to warrant finding a
`
`general
`
`solution
`
`for them, rather than letting each user solve the problems.
`
`These functions can often be performed hy library routines
`
`called by the user.
`
`Most user programs do not exchange
`
`random binary bit strings;
`
`they exchange things such as
`
`people's names, city names. dates, and amounts of money.
`
`The REMOTE PROCESS is the program to be downloaded as a
`
`bit stream of executaole code to the REMOTE NODF.
`
`Up to this point,
`
`the only thing the user on the
`
`SMART NODE needs to know is the network address of the
`
`REMOTE PROCESS to download. i.e.
`
`the Destination Address
`
`portion of
`
`the Ethernet frame fornat.
`
`Also,
`
`the only
`
`thins the REMOTE NODE needs to know is that
`
`the received
`
`REMOTE PROCESS is coming from the expected
`Ds..
`
`SMART
`
`NODE,
`
`i.
`
`. fron the expected Source Address.
`
`All
`
`these tasxs
`
`are supposed to be done at
`
`the Network Layer of the OSI
`
`Reference Model.
`
`For this reason,
`
`the REMOTE BOOTSTRAP
`
`and EOOT LOADER actually perform functions requested by
`
`the Network Layer only.

`
`2.2 Software Residency
`
`Wether or not
`
`the host computer is intends to talk
`
`with the network,
`
`the Ethernet Controller performs
`
`diagnostic tests when the host computer powers up, and
`
`then is ready for message traffic.
`
`The way the host
`
`computer talks to the Ethernet Controller differs from one
`
`implementation to another.
`
`The REMOTE BOOTSTRAP and BOOT
`
`IOADER perform the Network Layer only as we discussed in
`
`the preceeding section;
`
`thus the REMOTE BOOTSTRAP software
`
`can be linked and loaded in any area other than the area
`
`occupied by the REMOTE PROCESS or
`
`the Operating System.
`
`2.2.1 NIIQIG, NI2Q1Z and LSI-11, PDP'11 family
`
`Normally,
`
`the REMOTE NOIE would not have an
`
`operating system, and the bootstrap can be anywhere in
`
`memory.
`
`As we discussed in 1.1.2, we
`
`implement
`
`the REMOTE
`
`BOOTSTRAP with either a PDP-11/44 or an LSI-11/23, which
`
`has mass storage devices and terminal with it, as the
`
`simulated REMOTE NODE.
`
`For demonstration purposes,
`
`the
`
`LSI-11/23 will be used as a REMOTE NODE.
`
`we have to
`
`consider the memory location of the Resident Operating
`
`System and the downloaded REMOTE PROCESS.
`
`For
`
`the RT-11 Operating System,
`
`the Resident
`
`Monitor. User Service Routines. Device Handlers. and the
`
`Keyboard Monitor are arranged in the highest memory Just

`
`The lowest memory ($63-77? Octal)
`
`is reserved for the Trap Vectors, System Communication
`
`Area, and Interrupt Vectors.
`
`The best place for the
`
`REMOTE BOOTSTRAP is the area just below the Keyboard
`
`Monitor which the user program can not norwally reach.
`
`That way the downloaded
`
`REMOTE PROCESS can be treated
`
`as
`
`a
`
`usual user
`
`program (Normally starts fror the
`
`address of 190% octal) (See Figure 2.8).

`
`The iSBCe6/30. which is a
`
`bare
`
`computer,
`
`is
`
`a
`
`REMOTE NODE.
`
`We may load the
`
`REMOTE
`
`BOOTSTRAP in any
`
`location other than the area
`
`occupied by
`
`the
`
`downloaded
`
`REMOTE PROCESS. Our approach is to burn an EPROM with the
`
`absolute executable module of
`
`the
`
`REMOTE tnoorsraae,
`
`put
`
`the
`
`EPROM on
`
`iSEC86/3% board,
`
`then map the
`
`EPFOM in the
`
`lowest ROM memory (Fflflflfifi) as shown in Figure 2.9.
`
`with
`
`the LOC86 utility on the MDS machine,
`
`INTELE (1982),
`
`the
`
`relocatable module of the REMOTE PROCESS can be assigned
`
`to a certain memory location, assigned by the user,
`
`to
`
`form an absolute load module of the REMOTE PROCESS.
`
`The loader on the MDS machine always loads the
`
`executable module in the memory area,
`
`somewhere around
`
`50@fi0E,
`
`just
`
`above
`
`the
`
`iNDX
`
`operating system which
`
`supports the execution of the program on
`
`8286 or
`
`8088
`
`microprocessors.

`
`FUNCTIONAL DESCRIPTION
`
`The discussions in chapter 2 showed that both the
`
`REMOTE
`
`BOOTSTRAP
`
`and
`
`the
`
`BOOT
`
`LOADER
`
`perform as
`
`an
`
`interface between a host computer or PE and the Ethernet
`
`Communications Controller.
`
`3.1 Overall Block Diagram
`
`As we have mentioned in Section 1.1.3,
`
`the REMOTE
`
`PROCESS program is created and the executable module
`
`of
`
`the
`
`REMOTE PROCESS is developed on the host computer
`
`at
`
`the SMART NODE.
`
`The BOOT LOADER devides
`
`(disassemb1es}
`
`the
`
`REMOTE PROCESS code into packets which suit
`
`the size
`
`of
`
`the
`
`transmit buffer and sends the
`
`packets one after
`
`another to the network interface.
`
`The packets are then
`
`transmitted to the REMOTE NODE.
`
`After sending out each
`
`packet,
`
`the
`
`BOOT LOADER waits
`
`for
`
`an
`
`acknowledgement
`
`signal
`
`from the REMOTE NODE to make sure that
`
`the
`
`packet
`
`has been received by the REMOTE NODE correctly. when the
`
`last
`
`packet of
`
`the
`
`REMOTE
`
`PROCESS
`
`code
`
`is
`
`sent.
`
`an
`
`independent packet
`
`is
`
`constructed with
`
`the
`
`execution
`
`command and entry point of the REMOTE PROCESS to tell the
`
`REMOTE NODE to execute the REMOTE PROCESS.

`
`The REMOTE BOOTSTRAP receives the packets. which
`
`the
`
`network interface received over
`
`the coaxial
`
`cable,
`
`and
`
`stores (reassembles)
`
`them in
`
`the memory
`
`location
`
`piggybacked on the received packets. After each packet is
`
`received,
`
`the REMOTE EOOTSTRAP sends an acknowledgement,
`
`either positive or negative,
`
`to the
`
`BOOT LOADER to
`
`tell
`
`whether
`
`the packet was
`
`received
`
`correctly.
`
`when
`
`the
`
`packet which includes the execution command and the entry
`
`point of the REMOTE PROCESS is received,
`
`the REMOTE NODE
`
`starts executing the
`
`REMOTE PROCESS by simply jumping to
`
`the entry point of
`
`the REMOTE PROCESS.
`
`Figure 3.1 outlines the role the REMOTE BOOTSTRAP
`
`and BOOT LOAEER play in the overall
`
`logical architecture
`
`of the Ethernet LAN.
