High Availability Firewall – WatchGuard Firebox Vclass V60

A Centralized State Repository Approach to Highly Scalable and High-Availability Parallel Firewall

Conventional high-availability stateful parallel firewall suffers from low scalability due to two overlapping requirements: workload distribution and redundancy. To achieve high throughput, load-distribution with complex algorithm is conventionally employed, consuming a lot of resources and making the system susceptible to state-related attacks such as SYN-flooding. On the other hand, making th...

Identification of ectodomain regions contributing to gating, deactivation, and resensitization of purinergic P2X receptors.

The P2X receptors (P2XRs) are a family of ligand-gated channels activated by extracellular ATP through a sequence of conformational transitions between closed, open, and desensitized states. In this study, we examined the dependence of the activity of P2XRs on ectodomain structure and agonist potency. Experiments were done in human embryonic kidney 293 cells expressing rat P2X2aR, P2X2bR, and P...
