Basics on Riverbed WAN optimization Solution

 Today I am going to talk about basics of Riverbed WAN optimization solution. WAN optimization solutions that deliver broad-spectrum improvement of WANs and the name comes into the mind is Riverbed WAN optimization solution. With Riverbed products, enterprises can implement solutions that help them empower their distributed workforce while eliminating IT capital expenditures and simplifying IT management. 

  • With the help of Riverbed enterprise can Centralize distributed infrastructure like file servers, mail servers, network attached storage (NAS), and remote office backup systems without affecting remote users 
  • It is a challenge to share large files but with the help of riverbed you can share large files among colleagues on different continents 
  • Are you afraid of backup and replication over WAN links, well with Riverbed you can perform backup and replication over long distance WAN links and will have complete them during backup windows that were unachievable just a year ago 
  • Enterprises need not to upgrade the bandwidth of their WAN circuits as with the Riverbed you can deliver significantly more services on existing WANs

If you guys aware of the TCP, TCP has a window of packets that can be in flight from one end to the other , i mean between the client and server and when the window is full, the sender cannot send additional packets until the destination acknowledges receipt of at least some of what has already been sent. 

If the maximum window is too small, the throughput of the link will be limited by the rate at which each full window can be sent to the other side and acknowledged. 

This is bottleneck and should be rare, because well-specified mechanisms exist to allow TCP to use large windows, and most recent operating systems implement those mechanisms. However, settings on both clients and servers are usually more attuned to LANs than WANs, and it is unusual to find clients or servers with TCP stacks matched to WAN latencies. 

With the help Riverbed we can have :
  • High-performance, disk-based and memory-based data reduction 
  • TCP optimization 
  • Application- or protocol-specific optimizations 
  • Caching or local servers 
  • QoS - Quality of Service
  • Network visibility 
I knew the main concern for the enterprise or the campus network is to have the performance of the applications in the network, Is that ?
Riverbed products improve the performance of all applications running over TCP and also have application-specific modules that address chatty application protocols. This combination enables Riverbed solutions to accelerate the applications that enterprises care about most, and provides the ability to easily add more functionality over time. 

Riverbed products are architected to scale all the way from the largest data centres with clustered products down to software on a single user's devices. For organizations looking to optimize branch office operations, Riverbed offers a full line of Steelhead products that can be easily integrated into a customer’s network. 

There are thirteen models of Steelhead products to choose from, based on the bandwidth to the site in question, the amount of data being used, and the number of desired TCP connections and you can choose them as per the requirement in your network. The requirement is based upon the number of the users in your network. 

Are you looking for the mobile users and want to improve the productivity?
Yes with the help of the Riverbed stealHead mobile softwares which can be installed on a user’s laptop to optimize that mobile user’s communications with the data center. In effect, Steelhead Mobile software turns a user’s laptop into a Steelhead product, so that mobile users can enjoy the same performance benefits as workers in a Steelhead product-enabled branch office. 

I will come up with the full fledged SteelHead product portfolio and where what to use in my next article. Please let me know your queries and concerns to prepare the design in your enterprise or Campus networks.
