This paper presents some observations of data packet delaying in a real productive industrial telemetry system. It introduces the statistical analysis of measured Round Trip Time (RTT) values of used Internet Control Management Protocol (ICMP) and User Datagram Protocol (UDP) packets usually used in such applications. Scheduled ICMP delay measurements are simple to implement, while the UDP packets...
With the proliferation of the Internet, voice over IP and multimedia communication become more and more important. One of the protocol that facilitated this development is Session Initiation Protocol (SIP). SIP is a signaling protocol which manages the session establishment and termination. It can be based on UDP or TCP at the transport layer. In this paper, the strengths and weaknesses of SIP over...
In this paper, the performance of IPv4 and IPv6 are compared for both Client-Server and Peer-Peer networks. For both networks, IPv4 produced higher bandwidth for TCP protocol. For UDP, IPv4 and IPv6 showed insignificant bandwidth differences except for packet size of 384 bytes where IPv4 had better performance in client-server environment.
IPv6 offers variety of enhancements including increased addressing capacity, Quality of Service (QoS) provisioning, built in security through IPSec and improved routing efficiency, over IPv4. But moving from the current version of IPv4 to the future version of IPv6 is not a straightforward process due to their incompatibility and will consume significant amount of time. So for the coming years both...
Network configuration (NETCONF) is a widely used protocol to deploy configuration of network devices. NETCONF uses different transport layer protocols like secure shell (SSH), simple object access protocol (SOAP), or blocks extensible exchange protocol (BEEP) (IETF RFCs 4742 through 4744), and assumes availability of a high bandwidth network for successful configuration deployment. In a dynamic MANET...
A new network service framework highlighting the concept of service migration is presented in this article. The proposed framework take into account essential service quality factors, such as server loading, bandwidth, delay, and so on, and then dynamically migrates an ongoing service from a distant server to a new server with shorter "weighted network distance" to the client. As a result,...
