BGP/MPLSVPN Concept 1: VRF One of the security measures of BGP/MPLSVPN is routing isolation and information isolation. It is implemented through the VPN route Forwarding (VPNRouting Forwarding: VRF) Table and LSP in MPLS. On a PE router, there are multiple BGP/MPLSVPN concepts 1: VRF tables, which correspond to one or more sub-interfaces on the PE router, used to store the route information of the VPN to which these subinterfaces belong. Generally, t

Ii. Task ManagementTask management is the core content of the UCOS-II operating system. This chapter provides an overview of the following processes to introduce and summarize the knowledge of task management.To achieve complex task management, it

The operating system (Operating system, or OS) is a computer program that manages and controls computer hardware and software resources, is the most basic system software that runs directly on "bare metal", and any other software must be run with

In the μCOS-II system, no matter when the clock cycle occurs, μC/OS-Ⅱ will add 1 to a 32-bit counter, which is called by the user OSStart () the number starts from 0 when the initialization task and the execution of 4,294,967,295 beats are completed.

Returns the inverse hyperbolic sine of a number by the Asinh () function. The ASIN () function returns the inverse of a different value, and the result is a radian value between-PI/2 and PI/2. The Acosh () function returns the inverse hyperbolic

VPN clients can be provided Internet access by forwarding the traffic of the VPN user to the ISP's Internet network management. Implemented by creating a static route in the VRF of the PE router and specifying the next hop in the global routing

We break down the Multi-Protocol Label exchange technology into several major elements, hoping to help you understand the working principles of this technology. To facilitate understanding, we will use an interesting analogy to describe how the

congestion to the maximum extent. The MPLS function can be used to extend the MSTP Networking capability from the ring network to the GRID network, and multiple client services (including Ethernet, ATM, and frame relay) can be implemented through pseudo-line (PW) access and convergence, and then converge to the core data network through Tunnel, finally forming a full network-wide MPLS, bringing the advanta

the data arrives at the egress LER, the LER will remove the Label, restore the original data stream and transmit the data in the original way. In short, multi-service, stream classification, traffic planning, routing display, services of different levels, and IPQoS based on ATM are all key features of MPLS. The goal is to solve the problem of network expansion and provide a variety of network services on the same infrastructure. With the emergence of

, but also QoS information before adding tags for the data. In this way, in the future forwarding process, the LSR will only forward data based on the Label carried by the data stream in the form of Table query and exchange. After the data arrives at the egress LER, the LER will remove the Label, restore the original data stream and transmit the data in the original way. In short, multi-service, stream classification, traffic planning, routing display, services of different levels and IP QoS bas

As a new network architecture, SDN has become a hot topic in the industry. The open network it advocates represents a change in the concept of network construction from adapting network capabilities to actively adapting network capabilities to the needs of network applications. Separation of forwarding and control, centralized control, and open network programming interfaces are the main features of SDN network architecture. As the main SDN protocol, openflow hopes to use a new forwarding protoc

There are similar demands in Politics and Law networks and e-government affairs networks. How to provide a logically isolated, secure, and reliable virtual IP private network for various industries has become a technical proble

switch connects to the aggregation switch through multi-link bundling. On the one hand, it can completely avoid second-layer loops and make full use of the uplink bandwidth of the access layer. Note that STP should be enabled even in L2 Networks without loops to prevent errors in device configuration and physical link maintenance. At the same time, although the network does not have a loop, STP may still affect the L2 network across multiple data centers. For example, when the network topology
