label. To detect the failure of a tagged message at the data level, you first need to know how many labels should be on each link in the network that contains the tagged data message. Here are some simple scenarios as examples: 0 ordinary IPv4 over mpls,1 a label. (4 bytes, LDP distribution) 0MPLS VPN or atom, or 6PE or 6vpe,2 tags (8 bytes, one is the inner layer of the label MP-BGP distribution, one is the outer label LDP allocation) 0 Flow Engineering 2 labels.

aims to minimize route Jitter Caused by router Restart, reduces the waste of route computing resources and network bandwidth resources. Various router protocols such as OSPF, BGP, ISIS and MPLS protocol RSVP-TE and LDP protocols both need to support the GR function for Non-Stop Forwarding ). The core of the GR mechanism is that when the Router Protocol of a device is restarted, GR Helper can be notified to maintain a stable relationship between its n

ensure high capacity, high performance and high speed IP bearer network development requirements. With the development of the latest route exchange technology, the traditional test content such as route table capacity test, exchange and forwarding capability test, and even oscillating test cannot meet the test requirements of high capacity, high performance, and function-rich route exchange technology. For example: 1) The combination of OSPF and LDP promotes the development of VPLS technology;

is submitted to the server. When you click Submit RSVP, the form will be handed back to the RsvpForm method in the Home controller, which only renders the view again. Here we need the [HttpGet] and [HttpPost] annotations. Get is to get data from the server (apparently in this project it is the page), post is to send data to the server (here the data is the content of the form ). We write an RsvpForm overload method to process form submission. The cha

, QoS ). Currently, common QoS technologies include IntServ (RSVP) and DiffServ. The former uses the Resource Reservation method, that is, for each different application, the "End-to-End" dedicated channel is reserved on the network, to ensure that key applications enjoy dedicated bandwidth resources. Resource Reservation is a virtual leased line solution that ensures the transmission quality of key applications, but cannot achieve bandwidth sharing,

to such products. Principle 2: Classification and processing of data of different application types Another important manifestation of intelligent exchange is to automatically classify different types of data in the network and provide different transmission policies to ensure smooth operation of key applications, that is, QoS ). Currently, common QoS technologies include IntServ (RSVP) and DiffServ. The former uses the Resource Reservation method, t

data traffic of different original addresses is diverted through policy routing, enable hosts with different original addresses to access the Internet through different ISP interfaces and convert the hosts with different original addresses to different NAT addresses.

optimizing Layer 2 processing. This improves the performance by 10 times and reduces the overall cost of the system. Figure 4 shows the first generation of architecture.　 The third-generation exchange technology is not only based on the progress of the second generation, but also based on ASIC + RISC technology, which is an optional policy for layer-3 routing, multicast, and users) in terms of line rate performance, the total data throughput can exceed several million packets per second.

According to the investigation and analysis results, the amount of visual information obtained by humans accounts for about 70% of the total amount of information, and the application scope of video technology is constantly expanding. For video conferencing systems that rely on network operations, the network environment plays a decisive role in meeting results. Video conferencing supports the following network access methods: IP Network-Based System For small and medium-sized users and individu

The reason for choosing the layer-3 switch is as follows, it mainly solves the performance, reliability, and security and confidentiality issues in large networks. The CoreBuilder 3500 switch uses advanced distributed ASIC + RISC technology to provide Layer 2 and Layer 3 Switch communication capabilities for line speed. The total data throughput can exceed 4 million packets per second. Because a p

Because a policy-based service mechanism is used to support QOS, the FIRE can be used to introduce distributed data packets to process DDP.) data packets can be quickly and independently transmitted to the system, at the same time, dynamic classification of PACE technology and

According to director Li, TMIS actually unified the original independent small network into a layered and large physical network.

total number of Route tables, the query speed of the router is greatly improved, and the Memory and CPU requirements of the router are also reduced. This function is completed by the flag router. Because of the CIDR function, the total number of LVC instances required for the flag switch is greatly reduced. Support for IPCoS (ClassofService): MPLS provides interworking with the Class of Service (IP CoS), enabling telecom operators to provide CoS of different levels to the general public with hi

equivalent to their VPI/VCI. Because ATM uses a fixed short area for exchange, we can believe that the flag exchange can be an effective solution for IPoverATM applications. Under an event-driven system, the flag is bound to FEC, which has some significance. Such events can be divided into the following two types:One is data-driven binding, that is, binding when data streams are generated. The flag binding is created only when required. There are only a few items in the forwarding table. Indica

also modifies and supplements signaling and routing protocols. To solve the management problems of various links in optical networks, GMPLS designs a brand new LMP protocol; to ensure the reliability of optical network operations, GMPLS also improves the protection and recovery mechanisms of optical networks. Due to these features, GMPLS has become a very good means to implement ASON Control. The software implements GMPLS management, routing, path calculation, signaling, neighbor discovery, and
