GUIDELINE
1.0 SUBJECT: KANWIN Services & Publications
2.0 DISTRIBUTION: All Current Users
3.0 FROM: Donald C. Heiman, Director of DISC
4.0 PURPOSE: This guideline summarizes the services provided by the KANWIN network and associated publications.
5.0 BACKGROUND: The KANsas Wide area Information Network (KANWIN) is a statewide data communications network supporting the TCP/IP, IPX and SNA protocols. There are a variety of services available through KANWIN which are documented in other Standards and Guidelines. This guideline provides references to those documents. This should simplify the process of determining what services are of interest to an agency and how they go about getting more information on them.
6.0 PROCEDURE: The following references are to existing KANWIN services and procedures. New services and associated procedures are being added to KANWIN on a regular basis and the guideline will be updated accordingly.
6.1 What is KANWIN?
KANWIN is a collection of circuits, routers and other communications equipment that enable computers and people to exchange data across the state of Kansas and the world using the TCP/IP, IPX and SNA protocols. KANWIN supports point-to-point (dedicated) and frame relay connections from 56KB to 1.54MB speeds and dial-up access up to 28.8KB. KANWIN is managed by DISC. KANWIN is in addition to the existing SNA network and eventually will replace the SNA network for all SNA traffic in addition to the other protocols. Note that the SNA protocol WILL NOT be replaced, it will simply be carried by a different physical network. Likewise, KANWIN will replace the ISN for dial-up services.
6.2 How do customers get access to KANWIN?
Customers request access to KANWIN using the standard TSR (Telecommunications Service Request) mechanism used today for other DISC services such as telephones or SNA access. This process should start with the agency assigned Telecommunications Service Support representative.
6.3 What are the requirements/restrictions to connect?
The answer depends on the protocols that the customer wants to be routed over KANWIN.
6.3.1 TCP/IP
To route TCP/IP, the customer LAN must be assigned a unique set of addresses called a subnet and be part of a registered domain. This is necessary to insure there are no addressing or naming conflicts within KANWIN and the Internet. DISC Standard 5413 (DISC Standard on Kansas Wide Area Information Network TCP/IP Addressing and Naming) discusses how a customer accomplishes this.
6.3.2 IPX (Novell)
Like TCP/IP, there are naming and addressing (wire numbers) requirements. DISC Standard 6400 (Novell Local Area Network (LAN) Naming/Numbering) discusses how to meet this requirement.
6.3.3 SNA (IBM)
SNA is bridged rather than routed because of the nature of the protocol. KANWIN will transport SNA in token ring framing (LLC2). How this is accomplished depends on the nature of the customer equipment. In all cases, the customer's TSR must make clear what SNA is to be transported and the nature of the connecting equipment.
6.3.3.1 Token ring devices
If the customer has (or wants to convert to) token ring controllers, the controller(s) would be connected to a token ring LAN on a router and bridged back to the token ring on the front end processor (FEP) in the DISC data center.
6.3.3.2 SDLC devices
If the customer has SDLC controllers (most customer controllers), the controller will be connected to the serial port on a router and converted to LLC2 (token ring) framing for transport back to the FEP. This is done in such a way as to be transparent to the controller.
6.3.3.3 TN3270 (TCP/IP)
Some customers prefer to login to the DISC data center directly from their non-SNA workstations/PCs. This is accomplished under TCP/IP using the TN3270 protocol, an extension of TELNET, the terminal protocol. This does notrequire any SNA controllers and is available from token ring or ethernet LANs. The customer must have a TCP/IP 'stack' (software on their workstation which provides a TN3270 emulator). Most products today include TN3270 as a part of the package. This will provide terminal access to MVS and VM but NOT print support. See 6.4 for more information.
6.4 DISC Data Center Services on KANWIN
The MVS and VM mainframes are accessible via KANWIN. Terminal (TN3270), file transfer (FTP), and print services are available. DISC Standard 4409 (Usage of the MVS TCPaccess Product) gives an overview of these services and references more FTP detail on Guideline 4614 and TELNET on Guideline 4612. A Guideline on MVS print services on KANWIN will be available shortly.
6.5 Security and Usage Policy
Because of the open nature of KANWIN (in contrast to the SNA network, for example) and its interconnection to the Internet and other non-state agencies, a separate security and usage policy has been created which lays out the customer versus DISC responsibilities when connecting to KANWIN. In brief - DISC will secure the KANWIN infrastructure, customers must secure their own LANs and servers. DISC will work with customers to help construct an appropriate security solution for them. See KIRC-CIA Policy 4220 (Security Policy for KANSAS Multi-Protocol Network) for more details of this policy.
6.6 Dial-Up Services
KANWIN supports dial modems for access to the KANWIN network. The servers support terminal (VT100), SLIP, and PPP connections at speeds up to 28.8KB. Dial access is available through an 800 number (800-893-4936) and is billed per minute. To access this service, a customer must have a dial account with user id and password. This is obtained with a TSR as is done for ISN service. This dial service will replace the ISN dial service in the near future. A DISC standard for dial services will be published shortly.
6.7 What does KANWIN cost?
Customers are billed one of two ways for the connection of their LAN to a router (per workstation or by LAN). In addition, frame relay (remote users) are billed monthly for the frame relay circuit, DSU and a one time installation charge. Dial-up access is billed by the minute of connect time. KANWIN rates are documented in PPM 2200 (Rates for DISC Services - FY96).
