- OPERATIONAL POLICIES FOR INTERNET NET 128.109
- and
- THE CONCERT NETWORK
-
-
-
- I. Introduction.
-
- Our local Internet network, 128.109, is connected to NC
- campuses, government labs, and companies via the CONCERT
- Network by routers (mostly cisco) and by a few ethernet level 2
- bridges. It is then gatewayed at the CONCERT NOC to
- ANS/NSFNET. On the subnet 193 ethernet is a gateway on the
- national backbone. External routing is under the control
- of routing daemons on the backbone gateway.
-
- The policies stated herein are directed only to hosts,
- gateways, servers, etc. that are capable of sending and
- receiving IP and ARP packets and of routing IP packets to the
- subnet 193 ethernet.
-
- Local IP subnet administrators must realize that their local
- ethernets are just as much a part of the Internet as is the
- DDN Networks or the ANS/NSFNET backbone. What appears on
- the local ethernet can and may be transmitted across the coun-
- try and may do immense damage along the way. When an offend-
- ing node or network is identified, various Network Opera-
- tions Centers (NOCs) start a defined procedure to solve
- the problem. Procedures range from advising the
- local administrator to fix the problem to immediate discon-
- nect of the offending node. In no case are problems ignored
- for very long and the severity of the action is in relation
- to the seriousness of the event. Because we (network 128.109)
- must be responsible participants in the Internet and because
- we have had serious problems, it is necessary that we main-
- tain policies and procedures in the operation of our network.
-
-
- II. CONCERT Network Operations Center.
-
- NSFNET has recommended that regional and state networks set
- up a Network Operations Center for coordination, monitoring,
- and management of Internet traffic and activities. The CON-
- CERT NOC as described herein is modeled after other NOCs
- and is comprised of those persons at the MCNC Center for
- Communications responsible for maintaining the local
- Internet and its gateways and interfaces to the out-
- side world. These people must ensure that our ANS/NSFNET
- facilities do not disrupt the national nets and that
- we maintain good connectivity to the Internet for all
- statewide users. CONCERT will not make unreasonable demands
- upon local subnet administrators but cooperation is needed
- and local subnet administrators must be responsive to our
-
-
-
-
-
-
-
-
-
-
-
-
-
- requests. When problems arise we will advise the local
- administrator while we attempt to filter offenders at the
- bridges where possible. However, in severe cases it may be
- necessary to shut down links in order to clear the problem
- until the local problem is located. In general, any
- host/subnet generating bogus packets that make their way
- onto the Internet or cause disruption of routing on our
- local network will be cause for immediate action against
- the offending host/subnet.
-
-
- III. Local Network Administrator.
-
- Every local subnet (128.109.X) must have appointed an IP
- subnet administrator registered at the CONCERT Network
- Operations Center (NOC). Send mail to subnet-
- reg@concert.net to register an administrator or change
- registration. (An alternate may be advantageous.) The local
- network administrator will be the person contacted when
- problems arise with that particular local subnetwork. The
- administrator will be expected to respond with appropriate
- priority. Registration should include telephone number and
- mailbox. A US mail addresses is desired also. This person
- should be reachable during normal business hours. If it is
- important that your local subnet maintain connectivity nights
- and weekends, then provide a contact procedure for use at
- such times.
-
-
- IV. Host Registration.
-
- The CONCERT NOC maintains a registry of TCP/IP hosts within
- the network on ncnoc.concert.net. Subnet-administrators should
- ensure that their hosts are included as changes and additions
- are made. Registration should include host name, host type,
- IP address, and ethernet address. To register hosts, send
- mail to host-reg@concert.net.
-
-
- V. Connecting New Hosts.
-
- The NOC requests that all local subnet administrators
- advise the NOC of connection of new devices that participate
- in the Internet, including gateways and servers of any type,
- prior to connecting such devices. In addition, it is
- recommended that packets from such devices be filtered by the
- appropriate gateways and/or bridges until proper operation is
- verified. For new devices, notification should include host
- name, host type, IP address, and ethernet address. Advise
- the NOC via mail to host-reg@concert.net.
-
-
- VI. Technical Assistance.
-
-
-
-
-
-
-
-
-
-
-
-
-
- In order to assist the local IP subnet administrators in
- maintaining proper network configuration and routing
- information, the CONCERT personnel will provide a basic
- technical guide on how to set up a host/gateway for
- connection to the local network. Subnet administrators may
- request assistance with network problems by addressing mail
- to help@concert.net.
-
-
- VII. Subnet Assignments.
-
- Subnet numbers (128.109.X) are assigned by the NOC. Send
- requests for new subnets to subnet-reg@concert.net. Please
- understand that Internet address space is a limited quantity
- and be prepared to provide justification for your needs. At
- the same time the CONCERT NOC is prepared to provide
- addressing to meet those needs.
-
-
- VIII. Reporting Problems.
-
- To report problems with network operation or other abnormal
- network events, send mail to trouble@concert.net. Persons
- on this list have various responsibilities that collectively
- insure that any situation that might occur will get prompt
- attention. The CONCERT NOC can be reached at 919-248-1111.
-
-
- IX. Network Use Policy
-
- The CONCERT Network supports use policies in accordance with
- its supplier of Internet connectivity and will enforce those
- policies to the best of its ability. Intra-CONCERT use is
- generally less restrictive but CONCERT supports those ele-
- ments of Internet policy that demand network etiquette
- and due consideration for user's rights to privacy and free-
- dom from exposure to offensive material. Internet policy
- is contained in two documents available from
- ncnoc.concert.net, NSFNET.policy and ANSNET.policy.
-
-
-
- This document is available from the NOC via anonymous FTP.
- To obtain a copy, FTP to NCNOC.CONCERT.NET with login=anonymous
- and password=guest and change to the directory doc. Get
- file CONCERT.policy or CONCERT.policy.ps. Other information
- on IP networking is also available from host ncnoc.
