WebMux Network Traffic Manager
Enterprise-class Application Delivery Network Load Balancing Solution
Manages, Controls, and Secures Layers 4-7 Local Network Traffic
AVANU’s WebMux Network Traffic Manager is a high valued and affordable enterprise-class application delivery network load balancing solution. Bottom line savings (product cost, time, labor, maintenance) offering more performance value for a high return on investment.
Over the past decade, there has been a substantial increase in the demand to support real-time interaction and multimedia content over the Internet. The network traffic volumes have exploded where the application requirements are getting more sophisticated and stringent.
This is where WebMux plays a key role in the network infrastructure to assure peak performance and high availability of the network traffic. Its functions are to manage, deliver securely, and reliably local data traffic for TCP/UDP IP applications and services to and from the internal network of servers/server farms.
With the user-friendly interface, WebMux is designed to be simple and fast to deploy and manage while meeting the most demanding local traffic load balancing needs of your network.
The overall general benefits of an application delivery network load balancing solution are:
The traffic to servers are distributed among the server farm so that a site can handle more than a single server alone. Other features, such as SSL Offloading and HTTP cache, help reduce impact on server resources.
After a farm has been created, more servers can be still be added should more capacity be needed.
A farm contains several servers that serve the same site. If a server should fail, the WebMux health check will detect the failed server and send requests to the remaining servers. Therefore, keeping the site online.
Reduce Site Maintenance Downtime
Servers in a farm can be taken offline for maintenance without interrupting the site.
We encourage you to download our introductory WebMux Network Traffic Manager White Paper. This examines the world of application delivery network load balancing and introduction to what WebMux is all about.
Popular TCP/UDP IP applications and services support include but not limited to Skype® for Business Server 2015, Exchange 2010 and 2013 Server, SharePoint® Server, Xbox® Live Games Server, Internet Information Services (IIS) for Windows® Server, WebLogic®, WebSphere®, Unified Communications (UC) services (unified messaging, IM presence, team collaboration, audio/web/video conferencing, mobility, and VoIP), databases, FTP, POP, terminal servers, and web servers to name a few.
After extensive testing and validation, Microsoft in 2005 chose WebMux as one of the first three hardware load balancer (HLB) to support its Unified Communications (UC) Office Live Communications Server (LCS) Enterprise and Standard platform (today’s Skype for Business Server) for its excellent features, performance, reliability, and affordability. WebMux has evolved supporting many popular applications from other world-class companies including Cisco, IBM, and Oracle.
The WebMux setup and configuration wizards are one of multiple options that lowers the complexity bar when setting up an enterprise-class load balancing/ADC solution for today’s sophisticated applications and services. The wizards remove the need for any scripting and make the deployment of WebMux quick and easy. Current WebMux wizards are for Microsoft Skype for Business Server, Lync Server, Exchange 2010 and 2013 Server, SharePoint, LiteScape, Pexip Infinity, Oracle WebLogic, IBM WebSphere, terminal services, and HTTP/HTTPS servers.
Graphical User Interface (GUI) = Simplicity (Quick, Fast, Easy to Deploy and Manage)
The interface optimizes the use of smartphone and tablet mobile technologies that increases the WebMux management convenience and ease in today’s highly mobile work environment.
WebMux Flexibility and Scalable Platforms
WebMux High Performance
– WebMux uses the 64-bit processor platform and developed using intensive algorithms to provide the high capacity, reliability, and availability
– WebMux appliance models are built with the best-in-class server-grade hardware with up to 18-core CPU processing power to provide outstanding, feature-rich performance for extensive cryptographic, compression, and network traffic management functionality
WebMux Extensive Features (all models)
All WebMux models have four (4) load balancing operation modes with each mode having its advantage. The number of Arms refers to the number of physical networks. There are one or two LAN connections (typically External and Internal). Both IPv4 and IPv6 are supported and work in all operation modes.
One-Armed Single Network is a special case of bridging in which the WebMux bridges internally on one interface (that can be bonded for higher capacity). The bridge loop issue is elimiated. Note that all traffic is “source NATted” (aka SNAT)–so the WebMux becomes the client and the server does not see the IP address of the client. A limitation of this configuration is that an additional IP address must be assigned to the WebMux for each 65,000 simultaneous connections–because of that SNAT configuration and client-server relationship.
One-Armed Direct Server Return (DSR) the highest-performance option in cases where it is supported, also known as “Direct Routing” or “Out-of-Path (OOP)” this makes the WebMux the traffic director for incoming traffic but return traffic can route back bypassing the WebMux (unless the WebMux does SSL termination). Note that this requires a simple configuration of a “loopback adapter” on the servers and also not there is no performance advantage if SSL or TLS termination is required as the WebMux becomes the endpoint for the SSL/TLS security relationship.
Two-Armed Network Address Translation (NAT) is the required configuration when you have two subnets. It is the common “Destination” NAT configuration in which the clients connect to an IP address on the WebMux and the WebMux proxies to the back-end servers. The servers “see” the IP address of the client, as if the WebMux was not there. This is the required configuration when there are two IP subnets (Internet-side and Internal).
Two-Armed Transparent makes the WebMux an inline bridge–seeing all of the traffic below the IP layer and able to manage traffic without IP address changes. Note that, being a bridge, you must avoid bridge loops–having a circular path through inter-connected bridges. Also, being inline and Two-Arms, the load-balanced traffic flows through the WebMux.
