a link state packet, or lsp, is essentially a data message used in networking to exchange information about the connections and statuses between routers. think of it as a digital map that updates in real time, telling each router in the network about the paths it can take to send your ...
What is Link Control Protocol (LCP)? In computer networking, Point-to-Point Protocol (PPP) provides a standard way to transport multiprotocol data over point-to-point links; within PPP, Link Control Protocol (LCP) establishes, configures and tests data link internet connections. In a communicatio...
OSPF is a link-state protocol. A link can be considered as a router interface. The link state is a description of that interface and of the relationship with its neighboring routers. For example, a description of the interface includes the IP address and mask of the interface, the type of...
Distance-vector protocols, such as the Routing Information Protocol (RIP) Link state protocols, such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) Although these protocols are designed for different purposes and have different behavior characteristics, they ...
The Open Shortest Path First (OSPF) protocol is a link-state Interior Gateway Protocol (IGP) developed by the Internet Engineering Task Force (IETF).
Traditionally, link state protocols such OSPF, even if OSPF routers have complete view of the topology, never calculated a backup route. With LFA, a router calculate a backup path that can be used to route traffic, in case of a failure of a directly connected link or node on primary...
This means that a Simple Certificate Enrollment Protocol (SCEP) certificate's subject alternative name (SAN) must have a security identifier (SID) extension that maps to the user or device SID in Active Directory. The mapping requirement protects against certificate spoofing and ensures that ...
What is a persistent connection? A persistent connection, also known as a Hypertext Transfer Protocol (HTTP) persistent connection, refers to a network communication channel that remains open for further HTTP requests and responses instead of closing after a single exchange. Persistent connections are ...
To prevent loops from causing broadcast storms and making the MAC address table unstable, the Spanning Tree Protocol (STP) runs switches when redundant links are used on the network. STP is a basic feature of datacom products including switches, routers, and WLAN products. This chapter describes...
followed by the state, and so on, the post office won't deliver it. There is an agreed-upon protocol for writing addresses in order for the postal system to work. In the same way, all IP data packets must present certain information in a certain order, and all IP addresses follow a ...
