Network virtualization as an important research, will have a far-reaching effect on next generation network. However, the current studies of virtual network (VN) pay more attention to the utilization of the substrate network (SN) and optimization of mapping algorithms, whereas the course of mapping they ignore some serious weaknesses such as substrate network's high availability. This paper we forces...
This paper presents an inter-FE topology discovery technology on ForCES router, it introduced a new type of topology discovery protocol ITDP (Inter-FE Topology Discovery Protocol). ITDP broadcast the prescribed format of the ITDP packets to each ITDP protocol port when FE is initialized, adjacent FE put these information into a neighbor table after the receipt of ITDP message packet, constructed FE...
IETF ForCES (forwarding and control element separation) is defining specifications for interfaces and modular resources abstractions in open programmable network equipments. According to drafts from ForCES, resources in the forwarding element are described in the form of logical function blocks (LFBs), each of which has a single specific function of processing packets. In this paper, we first design...
