Virtual Extensible LAN Virtual Extensible LAN Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments. It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number. VXLAN endpoints, which terminate VXLAN tunnels and may be either virtual or physical switch ports, are known as VXLAN tunnel endpoints (VTEPs). VXLAN is an evolution of efforts to standardize on an overlay encapsulation protocol. It increases scalability up to 16 million logical networks and allows for
Task computing the following components: Using Task Execution EditoR (STEER), embodiments of multiple semantically described services and service controls, the following applications are possible: Task computing Task computing is a computation meant to fill the gap between tasks (what the user wants to be done) and services (functionalities that are available to the user). Task computing seeks to redefine how users interact with and use computing environments. It is built on pervasive computing. A Task Computing Framework (TCF) is a framework that supports task computing, by providing support for: This definition of a task computing framework does not make reference to computational
