The TCP protocol can be optimized by establishing a protocol tunnel to avoid subsequent 3-way TCP handshake
chattiness and ensuring that the tunnel is kept alive. TCP Acceleration also allows the administrator to set the TCP receive
window size to optimize the amount of data in flight given the environment characteristics and to set congestion
control algorithms to best match the environment. TCP Acceleration will also reduce chattiness and the amount of data
on the wire by acknowledging the receipt of packets in batches instead of acknowledging each packet individually. TCP
Acceleration also notifies ECN-aware (Explicit Congestion Notification) routers without dropping packets.
SSL Acceleration
– Provides acceleration for SSL encrypted connections.
SSL Acceleration provides acceleration of SSL encrypted TCP sessions by intercepting SSL connections to configured
servers and decrypting them, performing acceleration techniques, then re-encrypting them again. Only traffic to servers
that are explicitly configured is SSL accelerated. Any SSL traffic that the Exinda appliance sees that does not belong to a
configured server is ignored.
SMB Acceleration
– Provides layer 7 SMB1 and SMB2 (Windows File Sharing) protocol optimization.
SMB (Server Message Block), operates as an application-layer network protocol used for providing shared access to files,
printers, serial ports, and miscellaneous communications between nodes on a network. May also be known as CIFS
(Common Internet File System), where CIFS is a dialect of the SMB protocol.
SMB Acceleration is the file transfer specific component of the Exinda Application Acceleration Technology. To deal with
inefficiencies in the SMB protocol, the Exinda Appliance has several optimizations to improve the performance of
applications using this protocol, including reading ahead of the data stream, writing behind the data stream, and
caching meta data on files and folders.
NCP Acceleration
– Provides layer 7 NCP (NetWare Core Protocol over TCP port 524) protocol optimization.
NCP is used in some products from Novell. NCP is used to access file, print, directory, clock synchronization, messaging,
remove command execution, and other network service functions in these Novell products.
Configure TCP Acceleration
TCP Acceleration is the heart of Exinda's application acceleration technology. All accelerated connections pass through
TCP Acceleration. In order to accelerate traffic over the WAN, Exinda transparently proxies TCP connections at each end.
Both the client and server think they have established a connection with each other; however, they have connected
with their local Exinda devices.
In addition to facilitating other acceleration technologies like WAN Memory and SMB acceleration, TCP acceleration also
provides performance improvements over and above regular TCP, while being fully compliant with TCP.
You can configure various settings for TCP acceleration.
Acceleration occurs between two Exinda appliances. The appliances can discover other appliances on the network
that they can accelerate with. You can configure whether your appliance will attempt to discover other appliances and
which IP address your appliance will use when other appliances discover your appliance.
TCP acceleration and auto-discovery require the use of custom TCP options. If other equipment is stripping the
required TCP option from the TCP headers, you can specify that the TCP accelerated traffic must tunnel to avoid the
