      Direct routing: Algorithms and complexity 

      Busch, Costas; Magdon-Ismail, M.; Mavronicolas, Marios; Spirakis, Paul G. (2004)
      Direct routing is the special case of bufferless routing where N packets, once injected into the network, must be routed along specific paths to their destinations without conflicts. We give a general treatment of three ...

      A hybrid fault-tolerant algorithm for MPLS networks 

      Hadjiona, Maria; Georgiou, Chryssis; Papa, Maria; Vassiliou, Vasos (2008)
      In this paper we present a new fault tolerant, path maintaining, algorithm for use in MPLS based networks. The novelty of the algorithm lies upon the fact that it is the first to employ both path restoration mechanisms ...

      Universal bufferless routing 

      Busch, Costas; Magdon-Ismail, M.; Mavronicolas, Marios (2005)
      Given an arbitrary network, and a routing problem with congestion C and dilation D, a long standing open problem is to show the existence of bufferless routing algorithms with optimal performance guarantees (routing time ...
