Revision History: APP History

I. BACKGROUND AND PURPOSE

The UCLA Campus Backbone Network (CBN) is a high performance "network of networks" that interconnects the UCLA community, providing access to departmental computing resources, University of California system resources, and regional, national, and international networks. The network enables an individual at a single workstation to access many services on a variety of computers and numerous networks both on- and off-campus, including Internet access. Comprehensive security requirements cover all aspects of the network including physical access to equipment, as well as access to academic and administrative data. The network is designed to be highly reliable and operational 24 hours a day, 365 days a year.

This Procedure outlines the CBN usage guidelines, Information Technology Services’ (IT Services) protocol when performance or function of the CBN is seriously disrupted, and the process for UCLA departments and units to request CBN services.

II. STATEMENT

Responsibilities for networking on campus are based on a concept of departmental network autonomy. IT Services is fully responsible for the performance of the CBN and the infrastructure services provided therein. Campus departments and units are responsible for the operation and performance of their network and its components as well as end user support.

CBN Guidelines

  1. The CBN provides transport for the Transmission Control Protocol/Internet Protocol communication protocol. Other protocols cannot be supported unless previously converted through an appropriate gateway. Users are connected to the CBN via a school, division, and/or department/unit local area network (LAN) and the appropriate equipment. Individual workstations, computers, file servers, and/or gateways cannot be connected directly to the CBN.
     
  2. A consistent set of rules based on technical standards governs the establishment, upgrade, and modification of campus wiring schemes. The standards are computer network specific and require compliance with physical cabling parameters as presented in the document entitled “Communications Infrastructure Standard for UCLA” (contact IT Services for a copy).
     
  3. Access to and use of campus computer and network services is a privilege, and requires that individuals act responsibly and respect the rights of others, as well as the integrity of the systems and related physical resources. Users must observe all relevant laws, regulations, acceptable use policies, and contractual obligations.

CBN Disruption Protocol

Network activity that seriously disrupts, degrades, or threatens the performance or function of the CBN will be considered an emergency circumstance as defined in the UC Electronic Communications Policy. Under such conditions, IT Services may elect to protect the CBN by implementing a temporary block to contain the disruptive traffic. When such an action is taken, IT Services Network Operations will notify, as soon as possible, the Network Coordinator(s) (NC) responsible for, or affected by the block, as well as the UCLA IT Security Coordinator. The scope of the block will be the feasible minimum necessary to overcome the disruption. The block will be removed when the NC warrants that the disruptive traffic has ceased.
