Rd and RT (mpls vpn bgp)
Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE device can achieve
MPLS Multiprotocol Label Switching-Multi-Protocol Label exchange technology is a new technology that uses tags to guide high-speed and efficient data transmission on open communication networks. Its value lies in its ability to introduce the connection mode in a connectionless network. Its main advantage is that it reduces network complexity, is compatible with various mainstream network technologies, and can reduce network costs by 50%, ensure QoS an

Dilhao has a total of N textbooks, each of which has a difficulty value. Each time he answers a question, he will pick two textbooks for reference. If the difficulty of the two books is different, the more complicated the questions that result from dilhao, that is,The complexity of a question equals the absolute value of the difficulty difference between the two books.
This is the turn of ldxxx. He wants to ask about the problem by using the m book. dilhao wa

We can see this question, and we can think of one-dimensional difference at a glance.
However, this complexity is O (NQ), and obviously t
So how to optimize it?
We will find that in the difference ~ Within the L-1 range
The values added by the difference are the same as the X-axis, and the y-axis increases progressively.
The abscissa and ordinate values of the reduced values increase with 1 as the tolerances.
Then, we can divide th
Mobile data is one of the most promising Telecom businesses. It can meet the needs of various mobile terminal users to access the Internet anytime, anywhere, it can also meet the needs of data and multimedia communication between them. Mobile IP is one of the key technologies to implement mobile data services. It supports mobile terminals with fixed IP addresses to move freely on the Internet and keep communication uninterrupted during the mobile process. Multi-Protocol Label Switching (

Synchronous Optical Fiber Network (SONET) is an optical fiber transmission standard that focuses on the physical layer in the OSI model structure. Like SDH in the world, SONET was initially designed for the transmission of voice traffic over optical fiber networks. Like the first layer physical layer protocol, SONET is also used to ensure communication between various optical fiber network links. Over time, SONET evolved, including data services-such as frame relay,

Product OverviewTMX 880TM is a scalable, high-performance MPLS platform with industry-leading QoS processing capabilities. It is mainly used to transmit various services, such as ATM, frame relay, and IP addresses, in the carrier's core network. Its patented switching structure is used to dynamically support layer 2nd and layer 3rd protocols-including Multi-Protocol Label Switching MPLS), ATM, frame relay,
With the continuous and rapid development of the Internet, people began to rethink the quality, reliability and efficiency of their services. One of the key solutions is to use Multi-Protocol Label Switching MPLS) to comprehensively improve the performance of IP networks. This trend leads to the convergence of traditional routing protocols and ATM core technologies. One of the most important aspects is to allow MP

These IPOA technologies can be divided into two types: overlapping mod
