The previous document has already learned the information dissemination through OSPF, also introduced the CSPF and path's establishment RSVP work principle. What should we do next? You can forward customer data traffic along the tunnel interface in three ways: Static routing routes Policy Routing Policy Routing Automatic routing Autoroute So to be more blunt, this piece of content is the final phase of Te Tunnel, the key to the key. Just imagine

real-time data flow applications in the IP network transmission of RTP (real-time transmission protocol) and RTCP (real-time Transmission Control Protocol), there is guaranteed QoS quality services for the network RSVP (Resource Reservation protocol) and IP different service, etc. , there are a series of protocols such as G.711, g.728, g.723, g.729, and so on, which are digitally coded. But the current VoIP technology most commonly used voice establi

transport strategies to ensure the smooth operation of critical applications, which is commonly called quality of Service (QoS). The most common QoS technologies currently available are IntServ (RSVP) and DiffServ two ways. The former uses the way of resource reservation, that is, for each kind of application, the "End-to-end" dedicated channel is reserved on the network to ensure that the key application can enjoy the fixed bandwidth resources alo

typically implement wide-area high-speed connections with ATM backbone interfaces. Therefore, the real problem is the cost of building the network, the services hosted by the network, and the time to implement the network. If the customer needs to obtain data services, such as Internet connection, work at home, etc., IP network is the choice of course. The hardware and software to implement this network are not only easy to obtain but also reasonably inexpensive. ATM will become a solution for

dynamic routing computation for the connection establishment. This latest network state allows for current information utilization while collecting historical information to meet capacity planning needs, activating optimized triggers, and limiting routing capacity. Ii. Signalling components The network component is a common basic component used to describe the network function structure, which has nothing to do with the concrete implementation technology. At the ASTN control level, there are

with optical switching array and non-transparent photoelectric switching network. In addition, the Out-of-band approach can also be based on the needs of the different use of appropriate bandwidth. For example, if 10mbit/s Ethernet does not meet the requirements, we can use 100mbit/s Ethernet or even Gigabit Ethernet (Gigabit Ethernet) to form a management maintenance channel. 2. A signaling protocol that enables the rapid establishment and dismantling of end to end links This can be accompli

(mostly using IPtables to mark).Currently, the TC can be used by the filter has: Fwmark classifier, u32 classifier, based on the routing of the Classifier and RSVP classifier (for IPV6, IPV4), etc., wherein the fwmark classifier allows us to use the Linux netfilter code to select traffic, and U32 The classifier allows us to select the traffic based on any header. It should be noted that filter (filter) is inside qdisc and they cannot be used as the m

products, including third-layer switch CoreBuilder 3500 and edge switch SuperStack Ⅱ Switch3300, HUB and nic. According to director Li, TMIS actually unified the original independent small network into a layered and large physical network. 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

addition to increasing the interface bandwidth on the vro, no extra work is required to ensure QoS.Since data communication is not guaranteed by a recognized mathematical model, this method can only roughly use empirical values for estimation. It is generally considered that expansion should be performed after the bandwidth utilization reaches 50% to ensure that the interface bandwidth utilization is less than 50%.Implemented through end-to-end Bandwidth Reservation. This method uses

that all TCP packets are defined as data streams, and the Port Classifier is used as a Port Classifier. It specifies several special TCP ports as long data streams. Because classification requires packet header check for each packet entering the router, we need a quick classification algorithm.QoS Problems If real QoS can be achieved, it is of course the most ideal for the Internet to become a network for commercial applications. When network congestion is unavoidable, IETF puts forward some mo

allows you to create a path for the network data stream in advance. These reserved paths occupy special network resources. They can be manually set to an explicit path or automatically generate the optimal path as needed.Basically speaking, MPLS is similar to the ATM technology. It is specially designed for IP addresses, but also supports different transmission media such as ATM and PoS. Mark the exchange path LSP). Data streams are mapped to the corresponding path based on traffic requirements

running between TDM, followed by the L2 Switch interface L2SC), and finally the group exchange function interface PSC) the tag exchange channel between them.In addition, GMPLS functions are similar to MPLS. Establish a tag exchange channel by sending a so-called PATH/LABEL request message by using a RSVP-TE or CR-LDP. The PATH/LABEL request message contains a common tag request, which is usually a specific routing object and a specific parameter for

, support for CR-LDP and RSVP protocols.The ZXR10 core router implements all relevant protocols. ZXR10 MPLS also implements other functions, including:1. MPLS Fast Reroute function. When a node or link on the LSP fails, the node or link is automatically switched to the new LSP to ensure that the network service is not interrupted.2. Implement traffic engineering TE ). Through the CR-LDP to set the relevant nodes, through the traffic detection, determi

key third-generation structure of fire asic. This structure not only improves the performance of layer-2 switching, but also provides performance levels with more flexibility and line rate, such as layer-3 routing, multicast, and user-selectable policy services. The performance mismatch between Layer 2 and Layer 3 will no longer exist. The real layer-3 switching network structure can achieve both the performance of the layer-2 and the control capability of the layer-3 network, without compromis

cases, we are likely to implement different traffic control policies for different IP addresses. at this time, we have to use different classes to express different control policies. Filter rules in TC Filters are used to insert users into specific control policies (that is, different classes ). for example, now we want to apply different control policies (A, B) to the IP addresses xxa and xxb. in this case, we can use filters to divide xxa into control policy, divide xxb into control policy B.

regarded as a virtual representation of the physical structure. Therefore, the label switching channel indicating the low-level synchronous optical network circuit (SONET) must be nested into the high-level synchronous optical network circuit ｡ Similarly, a tag exchange channel running between optical switching cable interfaces (FSC) may contain a tag exchange channel running between switching function interfaces (LSC, the tag exchange channel running between LSC may include the tag exchange ch
