How Virtual Private Networks Work For site-to-site virtual private networks (VPNs), the encapsulating protocol is usually IPSec or Generic Routing Encapsulation (GRE). GRE includes information on what type of packet you are encapsulating and information about the connection between the client and server.

Open System Interconnection Protocols A network entity title (NET) is used to identify the network layer of a system without associating that system with a specific transport layer entity (as an NSAP address does). NETs are useful for addressing intermediate systems (ISs), such as routers, that do not interface with the transport layer.tub routing is commonly used in a hub and spoke network topology. In a hub and spoke network, one or more end (stub) networks are connected to a remote router (the spoke) that is connected to one or more distribution routers (the hub).

DEFINITION of 'Graduate Record Examination (GRE)' DEFINITION of 'Graduate Record Examination-GRE'. A standardized exam used to measure one's aptitude for abstract thinking in the areas of analytical writing, mathematics and vocabulary. The GRE is commonly used by many graduate schools to determine an applicant's eligibility for the program. The GRE is only offered via computer, however in areas which lack the appropriate computer networks, a paper-based exam may be given. Next Up.

EtherCAT The EtherCAT network is fully transparent for the Ethernet devices, and the real-time features of EtherCAT are not disturbed. Functional Safety: Safety over EtherCAT (FSoE) In parallel to the development of EtherCAT, a fieldbus-independent safety protocol has been developed. For EtherCAT, it is available as Safety over EtherCAT (FSoE = Fail Safe over EtherCAT). With FSoE, functional safety with EtherCAT can be realized. The protocol as well as the implementation are certified by TÜV and meet the requirements of the Safety Integrity Level 3 according to IEC 61508. Since 2010, Safety over EtherCAT is internationally standardized to IEC 61784-3-12.

Generic Routing Encapsulation (GRE) In essence, GRE creates a private point-to-point connection like that of a virtual private network (VPN). GRE works by encapsulating a payload -- that is, an inner packet that needs to be delivered to a destination network -- inside an outer IP packet. GRE tunnel endpoints send payloads through GRE tunnels by routing encapsulated packets through intervening IP networks.
