Virtualization and Cloud Computing

Image
What is virtualization? In a nutshell, virtualization is software that separates physical infrastructures to create various dedicated resources. It is the fundamental technology that powers cloud computing. "Virtualization software makes it possible to run multiple operating systems and multiple applications on the same server at the same time," said Mike Adams , director of product marketing at VMware, a pioneer in virtualization and cloud software and services. "It enables businesses to reduce IT costs while increasing the efficiency, utilization and flexibility of their existing computer hardware." The technology behind virtualization is known as a virtual machine monitor (VMM) or virtual manager, which separates compute environments from the actual physical infrastructure. Virtualization makes servers, workstations, storage and other systems independent of the physical hardware layer , said John Livesay, vice president of InfraNet , a network infrast

SIP-TIMERS “Timing is everything”

Image
      There are several aspects of SIP that ensure that messages are delivered on time. Three basic SIP timer parameters – T1, Timer B, and Timer F.  T1 is the estimated round trip time of an IP packet.  By default, T1 is set to 500 milliseconds which for many networks can be a little on the high side.   However, the SIP standard allows you to ignore the default and set it to something that better matches your network characteristics. The second SIP timer parameter is Timer B.  Timer B is the maximum amount of time that a sender will wait for an INVITE message to be acknowledged — i.e. a SIP response message is received. Timer F is the maximum amount of time that a sender will wait for a non-INVITE message to be acknowledged.  SIP messages such as REFER, INFO, MESSAGE, BYE, and CANCEL fall into this category. The way that Timer B and Timer F function is pretty straightforward.   Both timers default to 64 times T1.  If you take the T1 default of 500ms, Timer B and Time
