Security Considerations for WiMAX-based Converged Network
With WiMAX promising to solve the bandwidth bottleneck, many carriers are looking to networking OEMs to provide robust security solutions - particularly VPNs and firewalls - in their edge devices, allowing them to securely deliver feature-rich services to subscribers, while protecting their own networks. Software original design manufacturers are now entering the fray to ensure that device vendors can provide carriers with these next-generation converged platforms, while adhering to the strict certification processes and rigid standards of quality in shorter development cycles....
