@TechnicalJones: Tech Term - Unstructured Supplementary Service Data

By Leroy Jones, Jr. on November 21, 2011 6:47 AM | No Comments

Unstructured Supplementary Service Data (USSD)

Definition: A synchronous protocol of all GSM networks and handsets. It is generally associated with real time or instant messaging phone services.

There is no store-and-forward capability, as is typical of other short message protocols. Response times for interactive USSD-based services are generally quicker than those used for SMS.

General Packet Radio Service (GPRS)

Definition: A data service for GSM cellular carriers. GPRS added a packet capability to GSM.

GPRS data transfer is typically charged per megabyte of traffic transferred, while data communication via traditional circuit switching is billed per minute of connection time, independent of whether the user is actually using the capacity or is in an idle state.

SMS transfer over GPRS is much faster than over GSM.

@TechnicalJones: Tech Term - Application Level Gateway

By Leroy Jones, Jr. on September 16, 2011 4:24 PM | No Comments

Application Level Gateway

Definition: A firewall system in which service is provided by processes that maintain complete TCP connection state and sequencing.

Application level firewalls often re-address traffic so that outgoing traffic appears to have originated from the firewall, rather than the internal host.
