  • Assessing your options for increasing wireless LAN capacity

    Enterprises most often assess new wireless specifications in terms of speed, but capacity should also be at the top of the list due to the increased use of wireless LAN for functions that include file transfers and high-bandwidth video. Network engi... 

  • WAN optimization policy goes deep

    The nature of the branch office is changing. Previously, branch offices were small remote sites with groups of workers that had a single focus, such as sales or customer support. Generally these workers accessed the same narrow set of applications. B... 

  • enterprise WAN

    An enterprise WAN is a corporate network that connects geographically dispersed users areas that could be anywhere in the world. 

  • WAN optimization (WAN acceleration)

    WAN optimization, also known as WAN acceleration, is the category of technologies and techniques used to maximize the efficiency of data flow across a wide area network (WAN). 

  • Wide Area Ethernet (WAE)

    Wide Area Ethernet (WAE) or Ethernet WAN (also sometimes referred to as fiber or LAN extension service ) is a network carrier service that delivers high-speed wide area network (WAN) connectivity, utilizing Ethernet as the connection method. Positio... 

  • wireless WAN (Wireless Wide Area Network)

    A wireless WAN is a wide area network in which separate areas of coverage or cells are connected wirelessly to provide service to a large geographic area.

    Bandwidth is generally either (1) the amount of data that can be carried from one point to another in a given time period (usually a second) 

  • chatty protocol

    A chatty protocol is an application or routing protocol that requires a client or server to wait for an acknowledgement before it can transmit again. 

  • Packet Order Correction (POC)

    Packet Order Correction (POC) is a technique for dealing with out-of-order packet delivery. 

  • WAN clustering (geoclustering, high-availability clustering or remote clustering)

    WAN clustering, also called geoclustering, high-availability clustering or remote clustering, is the use of multiple redundant computing resources located in different geographical locations to form what appears to be a single highly-available system... 

  • capacity planning

    In information technology, capacity planning is the science and art of estimating the space, computer hardware, software and connection infrastructure resources that will be needed over some future period of time.
