The need for flexible protocol stacks in communication software, instead of static, predefined protocol stacks, has been more and more asserted these last years. We present here a new environment, COMSCRIPT, which addresses the implementation of flexible protocol stacks directed by the application. COMSCRIPT is a new programming language, derived from POSTSCRIPT, which follows an interpretative...

This paper proposes a protocol proxy scheme that can emulate the open shortest path first (OSPF) protocol in an effective and flexible manner. It is implemented in our developed network emulator, which is used to test network controllers for IP optical network management. In the protocol scheme, OSPF protocol emulation is achieved by combining an OSPF protocol proxy (introduced here) and an OSP...

This paper presents an approach to design a powerful and flexible controller architecture in order to support new applications across various heterogeneous networks. The approach allows a run-time configuration of the protocol modules. In contrast to existing systems, the developer has the choice to apply different implementation strategies to a module, changing in this way its encapsulation an...

Interconnecting heterogeneous devices, that is, devices with varying capabilities, has raised new challenges in the design of network protocols. This paper describes the design of the Flexible Interconnecting Protocol, or FLIP, whose goal is to interconnect heterogeneous devices. FLIP is a flexible protocol that addresses the needs of heterogeneous networks: it incurs little overhead when run b...

Previous modular protocol design and implementation allow a flexible configuration and reconfiguration of protocol layers or full protocol stacks. However, in our days, software engineering technologies introduce new methods for designing and specifying modular software. Such a technology is the component-based software technology. Using those techniques, a software system could be modular. Thi...

Providing a suitable authenticated key establishment protocol in MANETs is challenging due to all the characteristics of networks, such as communication capability, computation capability and storage resources. This paper presents an efficient and flexible authenticated key agreement protocol without bilinear pairings for MANET. Our proposed protocol not only provides mutual authentication betw...

background: recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (gnrha) at beginning of ovarian stimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (ivf) cycles. objective:the efficacy of gnrha stop protocol in poor responder patients in ivf cycles was assessed...
