Interactive Connectivity Establishment (ICE) is a technique used in computer networking to find ways for two computers to talk to each other as directly as possible in peer-to-peer networking. This is most commonly used for interactive media such as Voice over Internet Protocol (VoIP), peer-to-peer communications, video, and instant messaging .
The protocols are codified in a series of ETSI Technical Specifications. Many services can be created using CAMEL, and it is particularly effective in allowing these services to be offered when a subscriber is roaming , like, for instance, No-prefix dialing (the number the user dials is the same no matter the country where the call is placed ...
Version 2.0 featured improved web service support and was released on August 1, 2004. [10] No further versions have appeared since. Vignette had a demo version of an ICE-capable server named Site-to-Site in February 1998, aiming to show how the protocol could facilitate content exchange between websites. [11]
Radioglaciology is the study of glaciers, ice sheets, ice caps and icy moons using ice penetrating radar.It employs a geophysical method similar to ground-penetrating radar and typically operates at frequencies in the MF, HF, VHF and UHF portions of the radio spectrum.

An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposite flow directions of ice, analogous to a water divide.Ice divides are important for geochronological investigations that use ice cores, since such coring is typically made at highest point of an ice sheet dome to avoid disturbances arising from horizontal ice movement.
Ice caps accumulate snow on their upper surfaces, and ablate snow on their lower surfaces. [6] An ice cap in equilibrium accumulates and ablates snow at the same rate. The AAR is the ratio between the accumulation area and the total area of the ice cap, which is used to indicate the health of the glacier. [6]
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. [ 1 ] There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase ...
