Abstract: An embodiment method of loop suppression in a layer-two transit network with multiprotocol label switching (MPLS) encapsulation includes receiving a packet at a provider edge (PE) router for the layer-two transit network. The packet is stored in a non-transitory memory on the PE router. The packet is stored according to a packet data structure having an MPLS label field and a layer-two header. A time-to-live (TTL) attribute is then determined for the packet. The TTL attribute is written to the non-transitory memory in the MPLS label field. The packet is then routed according to information in the layer-two header.

Abstract: Embodiments are provided herein for creating virtual networks with service chains, such as n-tier networks, in the cloud. In an embodiment, a network diagram for a virtual network is received from a user via a graphical user interface. The network diagram comprises elements that represent virtual or physical network components. The network components include switches, routers, firewalls, links, service appliances, virtual machines, servers, or other network components. Upon successfully validating the network diagram, via a validation step, the network diagram is compiled into application programming interface (API) calls ready for execution. The executed APIs are used to establish the virtual network on a physical network infrastructure. The virtual network comprises virtual network components corresponding to the elements or the network diagram.
