Though Open Flow, the promising scheme for enterprise network control, can provide fine-grained and flow-level control in networks, yet it still has a few undesirable designs in security, scalability and performance. Inspired by many...
A virtual networked infrastructure (VNI) consists of virtual machines (VMs) connected by a virtual network. Created for individual users on a shared cloud infrastructure, VNIs reflect the concept of "Infrastructure as a Service” (IaaS) as part of the emerging cloud computing paradigm. The ability to take snapshots of an entire VNI—including images of the VMs with their execution,...
Group applications like the audioconference require a minimum level of quality of service for the adequate transmission of voice packets and the improvement of the signaling processes for joining, maintaining and leaving multicast groups. Traditionally, SIP servers have dealed with unicast signaling and have also been supported by IP multicast facilities described within the SDP payload information...
The network protocols we use today have been introduced decades ago. Since then the whole Internet came to existence and with it a single protocol stack: TCP/IP. What was a good solution back then, is no longer appropriate to fulfill the emerging demands of applications. Newer protocols have been created as solutions for the problems, but replacing TCP/IP requires a complicated deployment and migration...
