The Cisco IOS monolithic kernel does not implement memory protection for the data of different processes. The entire physical memory is mapped into one virtual address space. The Cisco IOS kernel does not perform any memory paging or swapping. Therefore the addressable memory is limited to the physical memory of the network device on which the ...
In order to push for scalability of networks, VPP reads the largest available vector of packets in the networks I/O layer.Instead of processing each packet individually throughout an entire graph with several nodes, VPP selects the entire vector of packets and pushes them through a graph node, before moving on to the next node.
Cisco IOS XR Line card running IOS XR. IOS XR is a release train of Cisco Systems ' widely deployed Internetwork Operating System (IOS) , used on their high-end Network Convergence System (NCS) and carrier-grade routers such as the ASR 9000 series and Carrier Routing System series of routers.
However, due to functional limitations, it is intended by Cisco to be used only as a learning aid, not a replacement for Cisco routers and switches. [9] The application itself only has a small number of features found within the actual hardware running a current Cisco IOS version. Thus, Packet Tracer is unsuitable for modelling production networks.
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. [2]It is built on Linux [3] [4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process [5] [6] and has a copy of IOS running as a separate process.

CCNA (Cisco Certified Network Associate) is an entry-level information technology (IT) certification offered by Cisco Systems. CCNA certification is widely recognized in the IT industry as the foundational step for careers in IT positions and networking roles. [1] [2] Cisco exams routinely change in response to evolving IT trends. [3]
Dynamic Multipoint Virtual Private Network (DMVPN) [1] is a dynamic tunneling form of a virtual private network (VPN) supported on Cisco IOS-based routers, and Huawei AR G3 routers, [2] and on Unix-like operating systems.
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. [1]
