Network Devices Naming Conventions

  1. 1. Network Devices Naming Conventions By Tekno Budi tekno.budi@fvtex.ca June 6th, 2016
  2. 2. Why Need A Good Naming Convention for your network  A proper naming convention can help shorten the time for troubleshooting as well as inventory.  Good naming conventions can safeguard your network from future problems
  3. 3. When to Consider Implementing a Naming Convention  A structured naming convention will be most useful in a large, dynamic environment that more complex and therefore require to be more organized.  If you are managing only a handful of computers, a naming convention may not be critical, but you may still need to give it some thought.
  4. 4. Whatever Naming Convention Make Sure Stick To It  Having a naming convention, and sticking to it at all times, is more important than what your naming convention entails.  As long as there is sound logic in your convention and it provides specific device information at a glance, you’re on the right track.  Consistency is important here. Having an erratic or non-existent naming scheme might not seem a problem on a small-scale network, but consider the hurdle on a large-scale network (WAN) such as in an ISP.
  5. 5. Key Features of Effective Naming Conventions  Parsability - Name made up of acronyms or identifiers that represent meaningful information to anyone reading the name.  Character Count - Standardised number of character count  Permanence - your devices – as well as your workspace – may move or change from time to time.  Logic - A logical framework should underpin every decision regarding your naming conventions.  Consistency - Whatever naming convention you decide on, stick to it at all times.
  6. 6. Common Language Location Identifier Codes (CLLI Codes)  A CLLI code is an 11-character, standardized, geographic identifier that uniquely identifies the geographic location of places and certain functional categories of equipment unique to the telecommunications industry.  To identify and describe three types of locations:  Network sites: network locations as central office buildings, business offices, microwave radio structures and earth stations.  Network support sites: International boundaries or crossing points, end points, fiber nodes, cable and facility junctions, manholes, poles and repeaters.  Customers’ sites: Customer locations and associated circuit terminations, facilities or equipment for each specific customer.
  7. 7. Who uses CLLI Codes?  CLLI code (pronounced as silly) is a Common Language Information Services Identifier used within the North American telecommunications industry to specify the location and function of telecommunications equipment or of a relevant location such as an international border or a supporting equipment location, like a manhole or pole.  Originally, they were used by Bell Telephone companies, but since all other telecommunications carriers needed to interconnect with the dominant Bell companies, CLLI code adoption eventually became universal. CLLI codes are now maintained and issued by Telcordia
  8. 8. Why CLLI Codes  CLLI codes offer a unique way of unambiguously identifying a location and its function. The code itself is concise and meaningful, enabling:  Process automation within and between service providers  Rapid understanding of the network through an enforced coding standard for network sites and entities. Reports may be compiled by finance and engineering using the same data, ensuring consistency.  A CLLI Code is required to obtain an NPA NXX code.  A CLLI codes are required in the ASR/LSR process.  The CLLI code is also used as a primary key into the database to enable further details to be understood about a location.  The CLLI code enables departments within an organization to refer to the same location in the same way, without risk of ambiguity where mistakes communicating location information can lead to expensive work around or litigation.
  9. 9. CLLI Code Basic Formats 1.Geographical Codes  cities, towns, suburbs, villages  Typically characters 1-4 in CLLI  Example: Calgary- CLGR 2.Geopolitical Codes  countries, states and provinces  Typically characters 5-6 in CLLI  Example: Alberta - AB
  10. 10. CLLI Code Basic Formats 3. Network-Site Codes  buildings, structures, enclosures  Typically characters 7-8 in CLLI  Example: Central Office - CO 4.Network-Entity Codes  identify and describe functional categories of equipment, administrative groups  Typically characters 9-11 in CLLI  Example: Digital Switch – DS0
  11. 11. CLLI Code Basic Formats  Network Support-Site Codes  Identify and describe the location of international boundaries or crossing points, end points, fiber nodes, cable and facility junctions, manholes, poles, radio-equipment sites, repeaters and toll stations.  Typically characters 7-11 in CLLI.  Example: Telephone PoleXXXX - P1234
  12. 12. CLLI Code Basic Formats  Customer Site Codes  Identify and describe customer locations associated with switched-service networks, centrex installations; trunk forecasting, cable, carrier or fiber terminations, NCTE, CPE and PBX equipment, military installations, shopping malls, universities and hospitals.  Typically characters 7-11 in CLLI.  Example: A Customer - 1A101
