WAN optimization is becoming an attractive option for companies that are growing globally and need to support an increasing number of large branch offices and remote locations. By some estimates, large enterprises have up to 80% of their workforce in regional locations, according to Nemertes Research.
All those workers want to be productive wherever they are. That means they need efficient access to important corporate data and enterprise applications under whatever circumstances they’re working.
In today’s distributed enterprise – where data volumes are growing and rich apps generate lots of network traffic and congestion – WAN optimization has become practically de rigueur to ensure more effective use of the networks that unite organizations.
WAN optimization improves response times for users of business-critical applications over WAN links or mobile connections, helping tackle application performance problems caused by bandwidth constraints, latency or protocol limitations. The technology continues to have as its main use optimizing the connection between remote users and centralized IT resources.
Optimizing data replication between data centers is another key function. Optimizing traffic to mobile devices and accessing externally hosted applications, like those in the cloud is also an important use case for the technology.
WAN optimization adoption is growing as cloud computing and SaaS apps gain a greater foothold in the enterprise, and as more companies look to the hybrid WAN model that lets them leverage combinations of MPLS, VPLS, VPWS, VPN and Internet and cloud connectivity services.
Masergy’s Managed WAN Optimization (MWO) allows for efficient use of WAN links to overcome the latency caused by physical WAN distances.
WAN Optimization achieves this through:
Data deduplication reduces the data that must be sent across a WAN for remote backups, replication and disaster recovery. Data compression shrinks the size of data to reduce bandwidth use. Data caching enables frequently used data to be hosted locally or on a local server for faster access. Application acceleration reduces or reorders message payloads to increase efficiencies.
Masergy’s MWO solution lets customers determine which traffic to prioritize and to allot bandwidth accordingly. Customers can be assured that data traversing a WAN-optimized link is the minimum required, thus preventing the incursion of additional bandwidth costs. Additionally, productivity is enhanced by shortening the time that users must wait for their application data.
A MWO device is need on each end of a WAN link. The managed device is typically installed between the customer LAN and router. And implementation is simple. A network engineer completes the device configuration and tests connectivity and troubleshoots any connectivity issues through the network equipment into the Masergy network.
WAN optimization helps IT departments fine tune application performance by optimizing packet size, data transfer rates and limit protocol “chattiness” across the WAN.
