Technology and Standards
As opposed to an unmediated bottleneck, a mediated bottleneck has properly deployed secure mediation controller (SMC) technology to insure that malicious and unfair use of the bottleneck cannot occur as well as enabling prioritization of bandwidth by recognizing Interstream Transit Keys (ISTKs). The SMC technology allows ISPs and network operators to define mediation policies for their network and temporarily escrow transit keys to enable use of premium services. InterStream's designated TCP implementation plus mediation of the bottleneck through use of the SMC will secure this aspect of performance in Internet bottlenecks.
In general, stages of service, employed today by router and switch manufacturers have an inefficient or suboptimal design which enable malicious and unfair use. TCP global (phase) synchronization can occur inside these bottlenecks resulting in not only unfair but also inefficient use. Unfortunately, current Active Queue Management (AQM) technologies such as RED and WRED do not entirely alleviate the problem. A more general approach must be taken which involves the development of a more efficient set of TCP algorithms along with their AQM counterparts. Through use of efficient TCP congestion control algorithms and secure queue management, bottlenecks may be mediated to distribute bandwidth appropriately to applications (or protocols) per a defined network operator's mediation policy.
Although this can be viewed as a bug, security defect, or performance optimization problem, it represents a broader problem. The Internet's 40 year history of protocol development must evolve to support a new secure yet open development paradigm.
