Overview
Exinda Networks solution is purpose-built appliance that has been developed from ground up to do both (a) QoS and bandwidth managment, and/or (b) LAN/WAN protocol and application acceleration.
The primary Exinda value and differentiator is up-to-date application awareness and ability to leverage these "Layer 7 signatures" to make granular bandwidth or acceleration policy decisions and provide insightful and extensive application-aware reporting.
An extensive list of Exinda bandwidth metrics are detailed HERE .
Deployment Basics
x700 series -- Bandwidth management
- Only ONE x700-series appliance required.
- x700-series appliance models leverage port pairs with ethernet bypass (ie. appliance is not a single point of failure).
- QoS, guarantee, and rate limiting policies leverage Exinda's awareness of (a) L7 application-layer (ie. AIM, BitTorrent, etc), and (b) protocol (eg. CIFS, HTTP, FTP, etc).
- Deployed at any point in network architecture where you want to manage bandwidth allocation for IP, protocols, or specific application.
- Typical deployment at network perimeter, immediately inside firewall(s).
- Best if Exinda appliance has visibility to end-user client workstations (ie. inside of any NAT occurring at firewall/perimeter). This allows for extensive reporting on workstation activity and bandwidth consumption.
- See topic attachment - Exinda Application Support - for document summarizing Exinda application signatures.
x800 series -- WAN/Application/TCP-IP Acceleration
- includes all x700-series features for IP traffic management (see above).
- all acceleration occurs between two Exinda x800-series appliances (ie. requires a minimum of two boxes).
- requires Exinda box on each end of WAN circuit being accelerated (ie. minimum of two boxes, but can typically leverage Exinda box already deployedat network core (see "bandwidth management" above).
- all acceleration policies can leverage the (a) L7 application-layer, and (b) protocol awareness.
- acceleration for TCP/IP protocol stack -- layer 3/4.
- protocol-specific acceleration (eg. CIFS, HTTP, CITRIX) -- layer 6/7.
- CIFS acceleration includes DISK- and RAM-based caching.
- acceleration WAN protocol layer -- (aka -- Exinda calls this "WAN memory" - and has something to do with reducing WAN latency, can improve throughput like 20-30%).
Additional Benefits
-
easy network object creation to produce powerful reporting.
-
All creation of network objects applies immediately to new AND EXISTING data. This is very powerful.
-
application-layer reporting: example: top web URL's and bandwidth used
-
high-availability configurations
-
copper port-pairs provide configurable hardware ethernet by-pass (aka "fail-open") to insure no single-point of failure. This is in addition to multi-path high-availability configurations.
