The Problem

Network managers trying to deliver high bandwidth, high performance access for international locations across oceans – say, in India, Brazil, Russia, China, Australia or Israel – have faced a quandary. If using Internet connectivity – say via IPSec VPNs – you frequently have difficulty getting acceptable application performance and file transfer rates across those long distances. WAN Optimization appliance solutions were not designed to work well when using Internet connections or over very long distance connections where congestion-based packet loss can be a frequent occurrence. Even if your budget allowed turning to MPLS, depending on the location it can take weeks or months to get installed. And if you are using MPLS, you’re paying a lot for relatively limited bandwidth, without any ability to burst above the subscribed bandwidth or easily add more, and you likely still frequently have trouble with application performance for things like remote file access.

If budgets were unlimited, the union of MPLS and purchased WAN Optimization appliances at all locations might well solve the performance problems, but for most organizations, budgets aren’t unlimited, nor necessarily are the availability of skilled personnel with time to manage the appliances. And even at that, this approach is not designed to support Internet-based access to cloud-based services or SaaS.

The Aryaka Solution

This situation is the ideal scenario for Aryaka’s WAN Optimization as-a-Service. It combines cloud-based, purpose-built WAN Optimization technology with enterprise-grade connectivity – utilizing a dedicated reliable core network based on globally distributed POPs close to business users– with centralized WAN and application-layer visibility. With our unique, multi-segment architecture, it is the best solution for delivering LAN-like performance for international WAN connectivity.

Our multi-tenant WAN Optimization technology deployed at each of our POPs offers application acceleration proxies for “chatty” protocols like CIFS and MAPI, data-deduplication and compression for bandwidth scaling, as well as generalized TCP optimization.

Our worldwide network of distributed POPs close to end users, coupled with our multi-segment architecture, is the key to providing high performance, reliable enterprise-grade global connectivity across oceans. Our dedicated core network with built-in diversity and redundancy provides reliability and stable, predictable latency connectivity across the globe between customer locations, as well as for accessing Internet-based SaaS and cloud services, avoiding the “middle mile” congestion problems that Internet-based connectivity solutions face.

How it Works

Enterprise locations connect to the Aryaka network over existing Internet links (or using direct L2 connec¬tions) using IPSec to one or more of our POPs, and can be up and running in minutes, not weeks or months. An optional network appliance is also available at no additional cost to provide bandwidth scaling at locations with low bandwidth or high latency links. The ability to burst above the bandwidth paid for provides even more capacity without extra cost.

Our patented multi-segment solution minimizes the impact of packet loss on the first/last mile when it does occur, delivering optimized, predictable performance. With our multi-segment approach, in addition to centralizing the complexity and management of higher level WAN Optimization technologies at POP locations, we enable full use of expensive bandwidth and more optimized, predictable performance for TCP applications running across long distance networks subject to packet loss.

We address the congestion-based loss problems faced by public Internet connections in two different, complementary ways. With our core network, we avoid the “middle mile” congestion problems that Internet-based connectivity frequently faces. With our POPs close to end user locations and using IP connectivity from Tier 1 ISPs, we minimize the amount of first and last mile congestion experienced. And by performing TCP termination and other TCP optimization functions per segment from edge to core and between core locations, rather than solely between distant appliances, as traditional WOC appliance solutions do, TCP connections between enterprise locations and Aryaka POPs are optimized to use available bandwidth and quickly retransmit packets in the face of first and last mile packet loss. Connections between POPs around the world are optimized for high bandwidth and high latency transfers.
