digital signals to your terminal devices. As the standards of digital broadband technology are not yet mature, FTTC is mainly used to transmit interactive narrowband digital services. The FTTC network can be upgraded to a broadband access network based on ATM. The ATM-PON provides users with more flexible broadband access, the downlink rate can be 622 Mbit/s or 155 Mbit/s, the uplink rate is 155 Mbit/s. One Passive Optical Splitter OLT) can connect 16 to 32 ONU, and one ONU can connect dozens o

This article mainly introduces Node. stream in js. This article describes what Stream, pipe method, Stream classification, and Readable Stream status switching. For more information, see What is stream? When it comes to stream, it involves the concept of * nix: pipeline-In * nix, the stream is implemented in Shell as data that can be bridge through | (pipeline operator, the output (stdout) of a process can be directly used as the input (stdin) of the next process ). In Node, the concept of Stre

backhaul scenario, data streams on different carriers of different nodes can be flexibly aggregated, which is one of the core hotspots of 3GPP Rel-12 standard and has been widely concerned in the industry. Inter-rat msa: provides multi-stream aggregation for users using multiple nodes of different standards Multi-stream convergence (Inter-rat msa) of different standards is a key technology to achieve the integration of different standards. The Host Layer can be UMTS or LTE, And the Boosting Lay

full spectrum resources. At present, nearly 40 frequencies in the 3GPP specification can be used for LTE. Operators can not only deploy LTE in new frequencies, but also deploy LTE in existing 2G and 3G frequencies. The best example is GSM1800 Refarming. 94 commercial LTE Networks have been deployed in the 1800Mhz band. While LTE provides band flexibility, operators also have to face the problem that the overall spectrum utilization is low because the spectrum is too scattered. To solve this pro

going through the complicated PPPoE authentication process. The access speed is greatly improved. In addition, to achieve unified network management, communication is required between BAS and other devices. These data packets are internal data packets and can be identified by vlan id. For downstream data, BAS is responsible for allocating and parsing the user's IP address, and also provides the gateway function. It receives the destination IP address

By comparing the filtergraph of both DirectShow and FFmpeg, the filtergraph operation of FFmpeg was analyzed.The first filtergraph is a graph, which consists of points and edges. The point in Filtergraph is the filter. In DirectShow, there is no edge object, the connection of filter depends on the pin component and the Ipin interface, and a pair of inputpin and Outputpin form an edge. Each filter can have at least one pin, that is, each point has at least one edge (excluding a plot with only one

introduction.1. In the speed-limit global configuration page, bandwidth management---speed global configuration, WebUI, enable the speed limit feature to select the "Enable granular speed limit" mode, which fills in the total number of Internet PCs and the upstream and downstream bandwidth of each internet line. 2. In the speed-limiting rules configuration page, bandwidth management, WebUI, select "All addresses" from the source address, select "All

RPR ring limit data frame is onlyThe fiber segment between the source node and the destination node is transmitted, and when the source node succeeds in sending a data frame, the data frame is collected from the loop by the destination node.Back. In this way, the data frame will no longer occupy the loop bandwidth of the downstream segment and improve the utilization of the ring bandwidth.2) Fair sex is goodFairness is a major guarantee that network

development platforms, you can use the. net platform to develop Web services without other tools or SDKs .. Net Framework itself fully supports Web services, including server-side request processors and support for sending and receiving SOAP messages to clients. Next, we will use Microsoft Visual Studio. net 20058 (VS. Net 2008) to create and use a simple Web Service. 2.1 create a simple Web Service First, open VS2005, open "file-new-website", and select "ASP. NET Web Service" Check the Servi

a lock, if successful, will give the lock set a very short expiration time, which is the same as the heartbeat expiration time. If the acquisition fails, the heartbeat continues to be detected. The slave that acquires the lock becomes master immediately and refreshes its heartbeat quickly, so that the other slave detects that the master offline fails and will not be called again tryLockMaster . Avoid the usual situation, always blocking, competition lock this road.Extensibility Extension Featur

, to achieve the purpose of service demotion, such as online product information, we must ensure priority access, and for the product information of the downline, we can allow the access capacity is limited, Allow access to the off-line product Details page.Increase asynchronous accessFor the low-real-time requirements of the operation, if the execution time is more time-consuming, through asynchronous processing to improve the performance of the caller, improve responsiveness, especially throug

from the top of the tag stack. Removing all labels is required by the outbound LSR. AddTo add tags to the message. If there is no tag, add the new one, which must be done by the inbound LSR. ExchangeReceives a tagged packet, switches it to the top with a new tag, and then sends it again. This is done by the LSR in the link. 4. LDP Workflow LDP is the protocol responsible for tag forwarding, 1) LSR discovery for running LDP 2) Session creation and maintenance3) Tag ing Notice 4) LDP needs to be

Original link http://f0g.is-programmer.com/posts/5458.html These two days have been overwhelmed by IGMP proxy, sometimes working, sometimes not working. Finally, I am very worried aboutCodeI finally found the problem and summarized it. The principle of IGMP proxy is to receive IGMP Report on the downstream interface, and then broadcast it from the upstream interface. At the same time, add the corresponding Virtual Interface (vif) on the router)

conditions of the straight pipe section, you should also leave enough operation space around the flowmeter, especially to leave a safe and convenient operation space for people, to facilitate installation, debugging, and repair. When the instrument is installed at high altitude, an operating platform should be created to ensure operation safety. 3. The flow meter can be installed on a horizontal, vertical, or skewed pipe. However, when measuring a liquid, the flow meter installed on the vertic

I still remember that I did the online and offline network stream question in the last year, but at that time I only set up the online graph creation method to understand the internal principles, therefore, when I encountered this question a few days ago, it was a little messy. So I learned it again and understood it deeply. It is estimated that I will not forget it again. Now, let's get down to the truth. This blog is well written for upstream and downstrea
