Virtual appliance - Relationship to WAN optimization

1 Software-based WAN optimization virtual appliances are an excellent

alternative to single-purpose hardware appliances, and enable high performance, agile and cost-

effective WANs which can act as solid foundations for those enterprises and

managed service providers considering virtualization and cloud

computing.https://store.theartofservice.com/the-wan-optimization-toolkit.html

Virtual appliance - Relationship to WAN optimization

1 Many WAN optimization virtual appliances (Certeon, Replify, Silver

Peak Systems etc.) have been certified by VMware.


Telecommunications in North America - Internet

1 Examples are to restrict Internet access by blocking the traffic

destined for a particular port or to affect the performance of certain

applications by assigning WAN optimization|priority.


Citrix Systems - Current products

1 * 'CloudBridge' (formerly WANScaler, Branch Repeater, NetScaler Branch

Repeater) optimizes application delivery to branch office users (see

WAN optimization).


Data deduplication - Benefits

1 * Network data deduplication is used to reduce the number of bytes that

must be transferred between endpoints, which can reduce the

amount of bandwidth required. See WAN optimization for more

information.


Data deduplication - Major players and technologies

1 * Druva Software|Druva offers source based deduplication in its Druva Insync|inSync (PC Backup) and

Phoenix (Server Backup) products. Main features include nCDP (near

continuous data protection), application-aware deduplication and

WAN optimization.


Bypass switch

1 A 'bypass switch' is a hardware device that provides a fail-safe

access port for an in-line monitoring appliance such as an intrusion

prevention system (IPS), firewall, WAN optimization device or unified

threat management system


Traffic shaping - Enterprises

1 WAN optimization and compression (WOC) on the other hand would use

compression and differential algorithms and techniques to

compress data streams or send only differences in file updates


CIFS - WAN performance issues

1 Solutions to this problem include the updated SMB 2.0 protocol, Offline Files, TCP window scale option|TCP

window scaling and WAN optimization|WAN acceleration devices from various network

vendors that cache and optimize SMB 1.0 and 2.0.

WAN optimization

1 'WAN optimization' is a collection of techniques for increasing data-

transfer efficiencies across wide-area networks. In 2008, the WAN

optimization market was estimated to be $1 billion, and it will grow to $4.4 billion by 2014 according to

Gartner, a technology research firm.


WAN optimization

1 WAN optimization has been the subject of extensive academic research almost since the

advent of the WAN. In the early 2000s, research in both the private and public sectors turned to improving the end-to-end throughput of TCP,

and the target of the first proprietary software|proprietary WAN optimization solutions was the Branch WAN. In recent years, however, the rapid

growth of digital data, and the concomitant needs to store and protect it, has presented a

need for DC2DC WAN optimization.


WAN optimization

1 Component techniques of Branch WAN Optimization include deduplication, Wide

area file services|WAFS, CIFS proxy, HTTPS Proxy, media multicasting, web caching, and bandwidth management.

Requirements for DC2DC WAN Optimization also center around

deduplication and TCP acceleration, however these must occur in the context

of multi-gigabit data transfer rates.


Middlebox - Types of middleboxes

1 * WAN optimization|WAN Optimizers improve bandwidth consumption and perceived latency between dedicated endpoints. Typically deployed in large

enterprises, WAN optimizers are deployed near both sending and

receiving endpoints of communication; the devices then coordinate to cache and compress traffic that traverses the Internet.


Application delivery network

1 In the branch office portion of an ADN is the WAN optimization

controller, which uses objectless caching techniques to reduce the number of bits that flow over the

network, and shapes TCP traffic using prioritization and other optimization

techniques


Application delivery network - Data compression and caching

1 A separate class of devices known as WAN Optimization Controllers (WOC)

provide this functionality, but the technology has been slowly added to the ADN portfolio over the past few

years as this class of device continues to become more

application aware, providing additional features for specific

applications such as CIFS|CIFS and SMB.


Network intelligence - Use in business

1 The network visibility afforded by NI can also be used to build enhancements and

next-generation solutions for Network performance management|Network

Performance Management, WAN optimization|WAN Optimization,

Customer experience management|Customer Experience Management,

Content filtering|Content Filtering, and internal billing of networked applications.

Blue Coat Systems - Acquisitions

1 As Blue Coat moved into the WAN optimization market, it shifted its acquisition focus to

companies with caching and performance technologies. In 2006, Blue Coat acquired the NetCache business from NetApp. In 2008, Blue

Coat acquired Packeteer, a bandwidth management company, for $268 million.

appliance to optimize the performance of enterprise voice,

video, and unified communications (UC), to ensure that remote users have fast and reliable access to all

centralized applications.


Wide area application services

offering the performance benefits that come along with using WAN

optimization technology


Wide area application services

1 By design, WAN Optimization “confuses” performance monitoring systems by

changing packet header data.[ http://www.networkperformancedaily.com/2007/07/whiteboard_series_the_impact_o.html The impact of WAN Optimization on

Network monitoring - Details

1 The widespread addition of WAN optimization devices is having an adverse effect on most network monitoring tools --

especially when it comes to measuring accurate end-to-end response time

because they limit round trip visibility.[http://www.networkperformancedaily.com/2007/07/whiteboard_series_the_impact_o_1.html The impact of WAN Optimization
