Themis will be powered by the ESA's Prometheus rocket engine. [1] Two possible landing sites have been mentioned in discussions surrounding the project: [2] The former Diamant launch complex, which will be used for the flight testing phase; [3] The Ariane 5 launch complex, which will become available after the transition from the Ariane 5 to ...
Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
Access time is the time delay or latency between a request to an electronic system, and the access being initiated or the requested data returned.. In computer and software systems, it is the time interval between the point where an instruction control unit initiates a call to retrieve data or a request to store data, and the point at which delivery of the data is completed or the storage is ...
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. In this context, the term "NAS" can refer to both the technology and systems involved, or a specialized computer appliance device unit built for such functionality – a NAS ...
[3] [10] [11] [12] An example of this type of network is a disaster recovery network where all nodes (generally people and vehicles) are mobile. [13] A second example is a vehicular network where mobile cars, trucks, and buses act as communicating entities. [3] A third consideration is the availability of network resources.
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
The history of delay-tolerant networking examines the bulk of the technologies that began the field that is known today as delay-tolerant networking.Research began as projects under United States government grants relating to the necessity of networking technologies that can sustain the significant delays and packet corruption of space travel.
CoDel (Controlled Delay; pronounced "coddle") is an active queue management (AQM) algorithm in network routing, developed by Van Jacobson and Kathleen Nichols and published as RFC8289. [1] It is designed to overcome bufferbloat in networking hardware , such as routers , by setting limits on the delay network packets experience as they pass ...
