A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
Virtual Router Redundancy Protocol. The Virtual Router Redundancy Protocol ( VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts.
The Multiple Spanning Tree Protocol (MSTP), originally defined in IEEE 802.1s -2002 and later merged into IEEE 802.1Q -2005, defines an extension to RSTP to further develop the usefulness of VLANs. In the standard, a spanning tree that maps one or more VLANs is called a multiple spanning tree (MST).
The table below shows the different paths and levels for Cisco Certifications. All Certifications, except for CCAr, requires the passing of one or more theoretical exams offered by Pearson VUE. CCIE Certifications also require a hands-on exam administered at special labs around the world.
Cisco said on Wednesday three of the top four cloud-computing companies were deploying its ethernet, as it reiterated a target of $1 billion worth of AI product orders in fiscal 2025.
Discretionary access control. In computer security, discretionary access control ( DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria [1] (TCSEC) as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong. The controls are discretionary in the sense ...
The Cisco Certified Internetwork Expert (CCIE) and Cisco Certified Design Expert (CCDE) certifications were established to assist the industry in distinguishing the top echelon of internetworking experts worldwide and to assess expert-level infrastructure network design skills worldwide.
The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco in 1998. The hierarchical design model divides enterprise networks into three layers: core, distribution, and access.
Open Shortest Path First ( OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the ...
Value engineering ( VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality. Value, as defined, is the ratio of function to cost. Value can therefore be manipulated by either improving the function or reducing the ...
