What is network control?
A control network is a network of nodes that collectively monitor, sense, and control or enable control of an environment for a particular purpose. A home appliance network is a good example of a control network. Unlike networks that people use to communicate with each other, control networks tend to be invisible.
What is NCP in computer network?
The Network Control Program (NCP) provided the middle layers of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet. NCP preceded the Transmission Control Protocol (TCP) as a transport layer protocol used during the early ARPANET.
What is the purpose of NCP networking?
The Network Control Protocol (NCP) is a mechanism used to establish and configure different Network Layer protocols for Point-to-Point Protocol (PPP) connections.
What is a type of network control protocol?
There are three main types of network protocols. These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP. Security protocols include HTTPS, SFTP, and SSL.
How does network access control Work?
How network access control systems work. NAC products enable device access to a network based on a specific, per device basis, with granular controls over what type and level of access is allowed. These controls are delivered by policies that are defined in a central control system.
What is TCP IP and what does it do?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of standardized rules that allow computers to communicate on a network such as the internet.
What is LCP detection?
In computer networking, the Link Control Protocol (LCP) forms part of the Point-to-Point Protocol (PPP), within the family of Internet protocols. The LCP protocol: checks the identity of the linked device and either accepts or rejects the device. determines the acceptable packet size for transmission.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. It can provide connection authentication, transmission encryption, and data compression.
What is Frame Relay used for?
Frame relay is a packet-switching telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between endpoints in wide area networks (WANs).
Which protocol is used for negotiation of IP address?
When the CPE sends Internet Protocol Control Protocol (IPCP) messages during the NCP negotiation process, the AAA server sends IPv4 or IPv6 addresses to the CPE. Based on a successful negotiation, PPP notifies the IP application that the IP service is activated.
Which PPP protocol allows a device?
The other three options are negotiated via LCP. Which PPP protocol allows a device to specify an IP address for routing over the PPP link? At the NCP layer, IPCP is responsible for configuring IP at both ends of the link. This allows the initiating node to specify an IPv4 address to use for routing over the PPP link.
What is TCP vs UDP?
TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
What are the types of VPN connections?
Here are five common VPN protocols and their primary benefits.
- PPTP. Point-to-Point Tunneling Protocol is one of the oldest VPN protocols in existence.
- L2TP/IPSec. Layer 2 Tunnel Protocol is a replacement of the PPTP VPN protocol.
