Some time ago in the development of a large insurance company project, among them, involves a risk-priced module, not before the insurance industry, a look at their insurance rate table, suddenly stunned, is a four-dimensional table, that is, four
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
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
1. Interconnection between different VRF: (Integration of intranet and external network)
The topic finally found a positive solution in the book.
There's always a question around me and some friends, if two vrf (companies) have access to each
single industry to a network service platform in multiple industries
As shown in figure 1, the original IP private network in industry a is transformed and upgraded to become a network service platform, providing network services for multiple industries at the same time. 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
At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN.

Parameter description:
Input-apply an access rate policy to the accepted packets on the portal
Output-apply an access rate policy to the sent packets at the egress
The access-group option applies the access rate policy on the specified access Control List-usually used when the specified ip address and application are limited.
Rate-limit: Optional. This is the rate-limit access control policy.

1. Should I use MPLS (Multiprotocol label switching) VPN?
For many business network needs, the answer is absolutely certain. The transition to MPLS is well underway.
Take a look at this data. MPLS VPN has been gobbling up the market for frame Relay for years, according to data from market research firm Vertical Systems Group. In the next 18 months, the number o
the optical switching structure is introduced. In addition, the fast search technology of Route tables, QoS Assurance, and MPLS network optimization are also being paid more and more attention to the introduction of optical switching in routers.
ASIC Technology
Because manufacturers need to reduce costs, ASIC technology has been widely used in routers. In a vro, to greatly increase the speed, the first thing you don't think of is ASIC. ASIC can be us
Currently, several new technologies that play a key role in improving the performance of routers mainly include the following: first, more and more functions are implemented in hardware mode, the improvement of CMOS integration technology enables many functions to be implemented on dedicated ic asic chips. The functions originally implemented by software can now be completed by faster hardware and lower costs, the system performance is greatly improved. Second, the distributed processing technol
Absrtact: Firstly, this paper introduces the expansion of MPLS to optical network, secondly, this paper expounds the application of the traditional electric domain switching technology in the optical domain, and finally analyzes the all-optical Internet solution based on label switching: Multiprotocol wavelength label Switching (mplms), lobs switching based on label Optical burst switch, all optical label packet switching olps.

I. Introduction With the continuous improvement of modern management methods, people's sense of time efficiency has been constantly strengthened. In the past, only people were not heard of their communication methods, affecting interpersonal communication.Multi-Protocol Label Switching MPLS) combines the label-based Layer 2 technology with the layer-3 routing technology, and introduces a connection-oriented mechanism in a connectionless IP address, A
Today we will talk about the establishment of LSP in the MPLS network by the Belkin router. I believe many people do not quite understand what the MPLS network structure is. I will give you a brief introduction below.1. MPLS network structure 1. The so-called MPLS network is the basic unit of the label exchange router
Ethernet transport networks, MSTP is not officially mentioned. The reason may be that we believe that MSTP belongs to the category of communication products or devices, and similar terms are inappropriate in rigorous technical standards, but in fact, the content of technical standard specifications is consistent with the actual MSTP product features.
Whether it's ITU-T or China's industry standard [1-6], MSTP integrates data business functionality, including asynchronous transmission mode (ATM)
As the network continues to expand, the volume of data traffic is growing, business increasingly complex, so that the existing network overwhelmed, people are increasingly unable to endure the best effort transmission mode.
On the other hand, Internet service provider ispinternet service Providers pay more attention to profit than ever before, the Internet urgently needs to expand on demand bandwidth consumption, fast and convenient route choice, Guaranteed quality of service qosquality of
interconnection problem between manufacturers is solved, the softswitch classification or full-plane routing mode can be gradually introduced.
2.2 Traffic Network Design
Due to the adoption of the Fast IP forwarding technology, the soft-switch route organization is flat and connectionless. QoS and security should be considered in the design of the traffic network. Currently, the IP bearer network is mainly implemented using mpls vpn technology. To ac
