Here is how we at SAVVIS name our devices -
1) Two letter country designation
2) Four letter telco city identifier
3) A single digit that indicates the facility within that city
Then it diverges for various functions. For example, for our Lucent
switches, there is a period, followed by aa, which indicates a CBX-500, af
which indicates a B-STDX 9000, or ag, which indicates a Gx-550.
For routers, it is a hyphen, followed by a convention for the model of the
router, then the function of the router (almost always c as our edge is
also our core)
For example, there is a circuit going between Columbus and Chicago. It
hits:
usclmb1.aa (CBX-500 in Columbus, OH)
uschcg2.ag (GX-550 taking a long-haul OC12 from Columbus and an OC12
going to the Juniper)
uschcg2-j20c (Juniper M20 in Chicago)
For a Cisco router - it would be uschcg3-c75c (that device actually
exsists too, it's at another location in Chicago) - the 75 indicates it's
a 7513.
