....we decided to use relatively lightweight language based technology. Interfacing Click to a high level type safe language, such as, Java, OCaml, Scheme etc. seems to involve prohibitive performance costs. Overheads of interpretation, marshaling, and garbage collection are the dominating costs [20]. Therefore, we decided to use a type safe but C like language, Cyclone [6] The type safety of Cyclone guarantees memory protection and its compatibility with C C makes it easier and efficient to interface with Click. To ensure safety and resource boundedness of untrusted code, RBCyclone ....

....The goal is to accelerate network services and to provide rapid and dynamic reconfiguration of the network infrastructure for the provision of Quality of Service. In contrast to the traditional networks, active networks can be customized and reconfigured on the fly in the presence of congestion [9] [15] On the other hand, active networks inherently exposures the underlying system to many security threats. Some of these threats include allowing malicious code to be injected into the network and granting resource access to unauthorized users that could result in denial of service to ....

....and authorization of a principal (network node or user) requesting action and dynamic resource naming. Besides the above, a mechanism in which active programs are distributed and security between routers pertaining to a session needs to be addressed. The performance of SANE has been documented in [174]. Shapiro et al. 175] propose the use of the Extremely Reliable Operating System (EROS) for providing a safe execution environment. Resource allocation control is done using capabilities. Certi cate mechanism is used to authenticate injected programs and a dedicated and controlled area for each ....

....their processing saves us additional communication over the lossy link. 5 Security PLAN was designed as a restricted language with the intention that programs using only services that provide appropriate protection would not require authentication. In fact, other active networking research [1] has shown that authenticating every active packet results in unacceptable performance degradation. On the other hand, for full advantage to be taken of the exibility of active networking, we want to allow PLAN programs to use services that require that packets be authorized. Functions ....

....cutover between different network topology standards. Work on the Active Bridge evolved into ALIEN [1] In ALIEN, packets can be programmed in a general purpose programming language (Caml) This requires more heavyweight security (based on SANE [4] on a per packet basis than PLAN, as reported in [2]. Sprocket is a language from the Smart Packets project at BBN [17] It uses a byte code language and is similar to PLAN in sharing a design goal to provide flexible network diagnostics. It differs from PLAN in that it targets a fixed set of service routines, and is designed with maximum ....

....in that paper, there is much room for improvement. In particular, our scheduling strategy, wire representation, and evaluation strategy drastically affect performance. On the other hand, we have found that by designing PLAN to be authentication free we can prevent costly cryptographic operations [2]. Furthermore, by including support for routing in the language (through the use of routing functions, like defaultRoute) we can avoid costly evaluations on every hop. Together, these optimizations represent up to a four fold increase in performance. For More Information. We invite readers to ....

....security and resource control models [22, 3] can safely extend the application range of the system, thus opening the infrastructure for third parties to perform monitoring functions. The trade offs between flexibility, security and performance have been studied extensively in active networks [2], and experimentation has shown that these functions can be appropriately restricted without excessive design complexity and performance cost. Note that ad hoc forms of active networking, in the sense of dynamic extensibility, have been explored to some extent in the case of active measurements ....
