Naming Convention

Domains

There are currently 3 Domains in COSMOS:

Testbed DomainDescription
bed.cosmos-lab.org Main deployment in NYC (name is short for testbed)
sb1.cosmos-lab.org Development sandbox at WINLAB, Rutgers University
sb2.cosmos-lab.org Forthcoming sandbox at Columbia University

Domains are controlled by the same central services, but cannot be sliced between either RF or networks.

Device Types

AbbreviationDescription
sw Ethernet switch
opt Optical switch
rdm ROADM (reconfigurable optical add-drop multiplexer)
srv Experiment dedicated Server
cm Out-of-band control device interface used by back-end services
sdr Directly addressable software defined radio (e.g. USRP 2974 or N310)
rfdev RF device that is separately managed (i.e. not part of the directly addressable SDR)

Outdoor Deployment Site Names

Map locations and GPS coordinates are only approximate and for rough reference only.

CU = Columbia University

Coverage measurements of the outdoor nodes when transmitting 802.11g WiFi data packets at 2.412 GHz are described here.

Hierarchical naming

Resources are named using the following scheme.

Devices that DO NOT belong to a specific sector of a large site:

{device_type}#-{site_name}#.{domain}.cosmos-lab.org

Devices that are part of a specific sector of a large site:

{device_type}#-{sector}#-{site_name}#.{domain}.cosmos-lab.org

Example of core resources:

Core 1 (co1)

Shared:
sw1-co1.bed.cosmos-lab.org
sw2-co1.bed.cosmos-lab.org
opt1-co1.bed.cosmos-lab.org
rdm1-co1.bed.cosmos-lab.org
rdm2-co1.bed.cosmos-lab.org
rdm3-co1.bed.cosmos-lab.org
rdm4-co1.bed.cosmos-lab.org
rdm5-co1.bed.cosmos-lab.org
rdm6-co1.bed.cosmos-lab.org
srv1-co1.bed.cosmos-lab.org
cm1-co1.bed.cosmos-lab.org
srv2-co1.bed.cosmos-lab.org
