Other Network ServicesQuality of Service (QoS)
With the QoS service, bandwidth allocation can be made upon request over the ULAKNET backbone for special applications that are highly sensitive to delays in order to prevent packet losses. For this service to be functional, additional configurations have to be made on university routers as well as on ULAKNET backbone. Therefore, universities and research organizations wishing to use this service are required to send the information requested in ULAKBIM web page to e-mail address network @ ulakbim.gov.tr until 2 business days prior to the planned start date of the application.
Multicast is a technology that enables efficient transfer of multimedia traffic such as voice and video from a server to multiple recipients on ULAKNET. Utilization of multicasting especially for applications such as Tele-medicine and videoconferencing brings in significant contributions to the ULAKNET backbone performance. Work is ongoing to enable multicast service support over IPv6 too.
With the relief on legal restrictions in 2004, plans are are being made to use the technology which enables carrying voice over the Internet instead of the telephone network -and shortly called Voice over IP (VoIP)- to facilitate the communications between the researchers over the ULAKNET backbone. The Voice over IP (VoIP) application shall provide for the transmission of voice and data on the same network without impairing voice quality. Various solutions can be produced for Voice over IP (VoIP) applications using PBX's, routers with VoIP or by IP phones.
