How does channel bonding work

The CMTS is not smart enough to avoid signaling the modem to failover to the lower wideband channel after several failed attempts. I only set up one fiber-node with 4 upstreams and 8 downstreams. I am able to do this because we are not utilizing our system until our WAN is upgraded. As soon as you think you have everything figured out you are working overtime again because the unknowns slap you in the face! It is possible to have 1 mac domain with all 8 DSs as primary and the proper wideband and integrated interfaces.

LOL on the last part. Too deep to go into here. First step is always look at physical layer. I am Vijay from India. SNR is from 23 to 26 dB in majority us ports. All DS from each card combined. Yes, it is very common to do 4 or 8 DS channel bonding on the MC20x20 cards. Also upstream channel bonding is very common. We currently have Docsis 2 and are upgrading to docsis 3. We currently use mhz and mhz for our downstream channels. We are hoping to add mhz and 99 mhz. Will 99 mhz and mhz work for downstream channels as I have read some articles that say to start at mhz.

Thanks, Ken. Great question to ask before moving to D3. Previous Next. View Larger Image. CER can be computed as follows: , Where: E u is the value of the count of code words with uncorrectable errors; E c is the value of the count of code words with correctable errors and; C is the value of the count of code words without errors.

More often than not this procedure is not exactly easy to achieve and has a few drawbacks. Usually, supported hardware is just too expensive, and purchasing a second Internet plan can be pricey as well.

However, you can turn to dedicated software solutions such as Speedify. Yes, using a VPN can often decrease Internet speed.

However, a good VPN will only decrease your speed by a small percentage and a great one can even boost your speed by circumventing ISP limitations such as throttling.

Packet loss is the inability of data packets to reach their destination point within a given connection. As a result, you might experience high latency, jitter, or even sudden disconnections. Commenting as. Not you? Save information for future comments. In casual Internet practice, channel bonding is rarely heard of, since it's rather complicated to achieve and has some drawbacks. Channel bonding uses at least two connections and combines them to increase the throughput between two or more connected devices.

Let's take a look at a high-level overview of an internet request. For the web page that you're currently reading to be loaded, your computer and browser connect to a server which delivers the necessary files. For this analogy, try to imagine your internet connection like a set of pipes. The various components of this web page like text and images are delivered as a packet of data over a socket.

Think of the socket as a pipe for information which extends from the server to you. If the socket is a pipe, then the packets are the liquid flowing through it. For example, the image that you see above was first broken into many individual packets and delivered through a socket.

It was then reassembled by your web browser. Load balancing is the approach which internet traffic is split among two or more internet providers.

In order to implement load balancing, you will need a router that is capable of multiple WAN connections. Each internet connection could be from a different provider or even different technology. For example, you could have the router connected to a fiber network and an LTE network simultaneously. Other than the costs, a client device is still limited to a single network connection at a time.

In the diagram above the network has access to two 5Mbps internet connections. If a single user wanted to stream a movie that required 8Mbps per second, load balancing will not be able to help.

This is because a movie stream requires a large single-socket transfer or pipe to deliver a movie from a server to you. Channel bonding splits your web traffic at the packet level among multiple internet connections.

This means that channel bonding will be effective even for the user trying to stream a large movie because traffic is split at a low level.
