Once connected to an access network, data is sent across multiple devices within it using internal routing protocols such as Internet Protocol (IP). This allows all devices on the same network to communicate with each other without having to go through external routers or switches. Access network...
NETCONF uses the Remote Procedure Call (RPC) protocol to carry out communications between clients and servers. RPC is a client/server protocol that lets a program request a service from another program without understanding the details of the underlying network. RPC messages are encoded in Extensible...
A set of cooperating network protocols is called aprotocol suite. The Transmission Control Protocol/Internet Protocol (TCP/IP) suite, which is typically used inclient-server models, includes numerous protocols across layers, such as the data, network, transport and application layers, working together...
Learn what a network access control list (ACL) is, its benefits, and the different types. This enables administrators to ensure that, unless the proper credentials are presented by the device, it cannot gain access.
SubNetwork Access Protocol (SNAP) refers to a standard used for transmitting IP datagrams across IEEE 802 networks. This means that the IP datagrams can be routed on IEEE 802 networks encapsulated inside the SNAP data link layers 802.3, 802.4 or 802.5, physical network layers, and the 802.2 ...
A network access server (NAS) is any device that handles remote logins to establish a point-to-point protocol connection. Some people call these devicesmedia access gatewaysorremote access servers. No matter what you call them, these tools handleauthenticationand ensure that people can tap into ...
What is a network protocol? In networking, aprotocolis a standardized way of doing certain actions and formatting data so that two or more devices are able to communicate with and understand each other. To understand why protocols are necessary, consider the process of mailing a letter. On the...
The compromised device is then connected to a network using UPnP, which grants hackers access to the network. Hackers can install whatever program they want after gaining access to the network through a backdoor that goes months without being noticed. ...
MPLS is considered secure even when data transmitted over an MPLS network is unencrypted, because it is based on a private link. However, individuals with physical access to the MPLS link could intercept communications. IPsec VPN data is always encrypted. However, because it traverses the public...
Network management encompasses the tasks network system administrators perform to provision, monitor, secure, operate and maintain data transfer channels.
