Token Ring 3000/iX for Series 900 Computers, Technical Data
For HP 3000 Series 900 Computer Systems Product Number J2167A
The Token Ring 3000/iX Link provides the hardware and software to
connect an HP 3000 Series 900 system to a multivendor LAN. The Token
Ring Link includes the hardware interface card and the device driver,
network transport, and network management agent software.
[Figure: Token Ring, Caption: none]
The network transport software includes the industry standard TCP, UDP,
and IP protocols, along with both the BSD sockets and HP NetIPC APIs.
Users may write their own software to access the network via an API, or
they may purchase one of the higher level networking services (ARPA, NS,
LAN Manager, or Novell Netware) provided by HP.
Token Ring Features
o A complete link connection to the Token Ring network, which includes
the Token Ring adapter and the transport software
o Full interoperability with IBM Token Ring
o 4 Mbits/second or 16 Mbits/second burst transfer rate
o Network transport software which provides the ARPA TCP, UDP, and IP
protocols
o BSD sockets API provides access to TCP and UDP
o HP NetIPC API provides access to TCP
o Integrated node management software provides online network
configuration and logging
o Supports Simple Network Management Protocol (SNMP)
o Supports Source Routing to remote connections through Source Routing
Bridges
o Supports VT (Virtual Terminal) access
Hardware Components
The Token Ring adapter card manages packet buffering, processes IEEE
802.5 protocols, and uses an LED to display the Token Ring adapter
status.
A 9-pin D-type connector on the Token Ring adapter card is used to
connect the adapter to the Token Ring network through a cable that plugs
into a Multi-station Access Unit (MsAU). On a 4 Mbit/second Token Ring
network, the following IBM cable types are supported:
------------------------------------------------------------------------
Data Grade AWG Type
------------------------------------------------------------------------
Type 1 22 2-wire shielded twisted pair
Type 2 22 2-wire shielded or 4-wire unshielded twisted pair
Type 3 22,24 twisted-pair unshielded
Type 6 26 2-wire shielded twisted pair
Type 9 26 2-wire shielded twisted pair
------------------------------------------------------------------------
For unshielded twisted pair (UTP), the customer will need to use a media
filter which attaches to the DB9 connector. This is done for impedance
matching from 150 Ohm (shielded twisted pair) to 100 Ohm UTP.
Additionally, only shielded cables are supported at the 16 Mbit/second
data link rate.
Features
o Uses TMS380C16/04 TI Token Ring communication processor
o Uses 512K bytes of DRAM space for MAC code and data storage
o Uses frame size up to 2048 bytes
o Supports early token release at 16 Mbits/second
o Supports up to 250 link stations
o Environmental: Class B2
o EMC: complies to FCC A and VDE Level B

Software Components
The Token Ring Link includes software corresponding to layers 2
through 4 of the Open Systems Interconnection (OSI) Reference Model (see
Figure 3). It also includes node management and network management
agent software (SNMP).
The Data Link Layer, corresponding to OSI layer 2, consists of the
link level IEEE 802.5 protocol. Transmission consists of sending
addressed frames of data on the cable at a signaling rate of either
4 megabits per second or 16 megabits per second.
The Network Layer, corresponding to OSI layer 3, is based on the ARPA
Internet Protocol (IP). IP provides packet fragmentation/ reassembly
and internetting capability.
The Transport Layer, corresponding to OSI layer 4, is based on the
ARPA Transmission Control Protocol (TCP) and User Datagram Protocol
(UDP).
TCP provides end-to-end reliable, connection-oriented services over
IP with flow control and multiplexing. TCP also has mechanisms for
detecting duplicate, lost, or out-of-sequence packets. UDP provides an
unacknowledged connection-less delivery service over IP.
The Token Ring Link provides two application programmatic interfaces
(APIs) to the network transport, Berkeley (BSD) sockets and HP's Network
Inter-Proccess Communication (NetIPC). Both APIs support the rapid
exchange of data using peer-to-peer communications between processes.
The processes may be on a single system or on different systems on the
network.
BSD sockets provides a C language interface to TCP and UDP. BSD
sockets is available on HP 1000s, 9000s, and PCs and on a wide range of
computers from other vendors. BSD sockets is part of the MPE/iX FOS
beginning with release 4.0 and is supported over the Token Ring Link.
The following sockets calls are supported:
- accept()
- bind()
- close()
- connect()
- fcntl()
- gethostby xxxx
- getnetby xxxx
- getprotoby xxxx
- getservby xxxx
- listen()
- recv()
- recvfrom()
- select()
- send()
- sendto()
- shutdown()
- socket()
- socketpair()
Additional sockets calls are planned for later releases.
NetIPC is a set of 18 programmatic calls, appropriate for implementing
efficient distributed applications over TCP only. NetIPC supports
communications to various HP systems, including the HP 1000, 3000, and
9000 computer systems, as well as HP PC networking. Applications
written to NetIPC can also interoperate with other applications written
to BSD sockets.
Node management software is included in the Token Ring Link and
provides a user interface for configuration, tracing, and logging. An
on-line user configurator supports easy initial configuration and
reconfiguration of the Token Ring Link software without bringing down
the HP 3000. The node management software also delivers flexible event
logging and the ability to selectively trace several levels of network
software. Also included is NetTool, a set of tools to monitor, analyze,
and diagnose the network transport software.
The Token Ring Link also includes a network management agent. The
agent supports the Simple Network Management Protocol (SNMP) and
collects information regarding the state of the link and transport.
This information is used and displayed by remote management stations,
such as the HP OpenView Network Node Manager (see related products
below). Standards
The protocols utilized by the Token Ring Link software closely adhere to
the following IEEE 802.5 standards:
o RFC 768 UDP
o RFC 791 IP
o RFC 792 ICMP
o RFC 793 TCP
o RFC 826 ARP
o RFC 919 IP Broadcast Datagrams
o RFC 922 IP Broadcast Datagrams with Subnets
o RFC 950 IP SubnetExtension
o RFC 1155 Management Information (SNMP)
o RFC 1157 SNMP
o RFC 1213 MIB II (SNMP)
Support for Networking Services
The Token Ring Link supports the multivendor ARPA network services,
Network File Services (NFS), HP's NS network services, Novell Netware,
and LAN Manager. The products provide interactive and programmatic
facilities, such as file transfer, remote database, file, and peripheral
access.
Network Capacity and Performance
Although the signaling rate of the line may be 4 or 16 megabits/s,
the throughput achieved at a node may be lower. This is primarily due
to the overhead of the software providing network services and the
user's application programs. Among the factors affecting user
throughput are the type of software being used, the main memory and
speed of each processor (and its peripherals) involved in the transfer
and the load on each system from non-network applications.
Because of the number and complexity of these factors, it is
difficult to make useful generalizations about the performance or
capacity of the network in a particular application. Hewlett-Packard
network specialists are available to consult in network design. They
have data on the system and network parameters that affect network
operation. With this information and an accurate understanding of the
target environment, they can assist in designing an effective network.
Installation and Configuration Policy
The customer is responsible for loading the Token Ring Link software
onto the system. HP will install the Token Ring card and perform
minimum configuration of the Token Ring Link to verify minimum product
functionality. This activity is included in the product's purchase
price.
Customer Responsibility
Prior to having HP personnel on-site to verify the installation and
perform minimum configuration of the Token Ring Link, the customer is
responsible for the following:
o Installing the appropriate wiring.
o Complying with all applicable building codes in the installation of
the Token Ring cabling and components.
o Obtaining a valid IP address prior to the configuration of the Token
Ring Link.
o Providing HP with the information necessary to complete the Network
Implementation and Support Plan (NISP) including:
o System configurations.
o Logical network map identifying relevant traffic flow.
o Physical network map identifying relevant network hardware components.
o Updating the HP 3000 system to the proper release level and installing
the Token Ring Link software using AUTOINST. Refer to the HP 3000
MPE/ix Installation and Update Manual (36123-90001).
o Verifying that all of the necessary software modules have been
successfully installed by AUTOINST and are at the correct version
levels using the NMMAINT.PUB.SYS utility.
o Performing full system backups (as necessary) and ensuring that the
HP 3000 system and personnel with HP 3000 system management experience
and LAN management experience are available when HP is on- site to
complete the installation and minimum configuration of the Token Ring
Link.
After HP has completed the minimum configuration of the Token Ring Link,
the customer is also responsible for completing the configuration in
order to fully integrate the Token Ring Link into the existing customer
network.
HP Responsibility
Following the installation of the Token Ring Link software, HP is
responsible for the following:
o Verifying the operation of the Token Ring card.
o Confirming that all of the necessary software modules have been
installed and are at the correct version level.
o Configuring the Token Ring Link product to the minimum default
configuration necessary to verify software and hardware functionality.
This default configuration includes configuring the link and network
interface in the network configuration file (NMCONFIG) using the NMMGR
Utility.
These steps complete HP's portion of the installation and minimum
configuration of the Token Ring/ix Network Link.
