A New Digital Signature and Certificate Architecture with Shortest Certification Pathposed approach can be used without reconstructing the structure of the existing PKI system and always allows a certification path whose length is 1 regardless of the distance between the users. This is because each user confirms only the digital signature of root CA in the combined hierarchical-network infrastructure.

Performance Modelling and Evaluation of Firewall Architectures for Multimedia Applicationsa firewall architectures. This model can be used to dimension firewalls for usage with multimedia applications. In addition, we present the results of a lab experiment, used to evaluate the performance of a distributed firewall architecture and to validate the model.

A Case for Mesh-Tree-Interaction in End System MulticastingTI uses the concept of mesh and enables interactions between the mesh and the underlying multicast tree. Our simulation studies show that MTI results in significant improvement in the quality (average delay metric) of the multicast tree.

On Core Selection Algorithm for Reducing Delay Variation of Many-to-Many Multicasts with Delay-Bound[18] that is known to be most effective so far in any network topology. The enhancement is up to about 11.1% in terms of normalized surcharge for DDVCA. The time complexity of our algorithm is .(mn.).

A Multi-level TCP Model with Heterogeneous RTTsrporates the effect of packet losses and RTTs on the goodput, as well as limited sending rates. Also, the unequal sharing of bandwidth between flows with different RTTs can be treated. The delay estimates take into account the initial slow start. Extensive ns2 simulations are used to verify the accuracy of the models.
