What is a virtual link ?
نویسنده
چکیده
Several authors have recently studied virtual knots and links because they admit invariants arising from R-matrices. We prove that every virtual link is uniquely represented by a link L ⊂ S×I in a thickened, compact, oriented surface S such that the link complement (S × I) \L has no essential vertical cylinder.

متن کاملAnalysis of a Scheduler for Virtualization of Links with Performance Isolation
In this paper we deal with a scheduling algorithm that creates several virtual links on one physical link by switching the service between the virtual links. The switching is done in such a way that the physical link is available for each virtual link for a constant time, what provides full performance isolation between virtual links. Firstly, we present a detailed analysis of the scheduler, in...
