Telnet

Don’t let sluggish and unreliable WAN connections slow Telnet. Silver Peak improves Telnet performance across distance. With Silver Peak, "telnetting" to a work location can be effective even over long distances or congested networks.

Telnet provides an interactive, text-based communication that is commonly used by administrators to log into remote devices and servers. While Telnet may perform just fine across local networks, across the wide area network (WAN) Telnet sessions can become unresponsive while logins may take too long.

Telnet is not the problem; it’s the underlying wide area network (WAN). The throughput of the session is limited by the delay on the network, which results from numerous factors including distance, routing policies, and peering practices. The effects of network congestion commonly found on private network services and especially the Internet  only exacerbate the issue. Purchasing more bandwidth does not help the problem and only serves to increase operational expenditures.

Silver Peak eliminates Telnet’s challenges by fixing the network’s underlying problems. Silver Peak’s algorithms minimize the amount of bandwidth required by Telnet, overcome latency by improving protocol efficiencies, and compensate for the effects of congestion. The result: a faster, more responsive Telnet session. More specifically, Silver Peak solves the following network challenges:

• Bandwidth  – Silver Peak byte-level deduplication removes redundant Telnet data from the WAN. The first time Telnet sends data it is fingerprinted and compressed by Silver Peak. Subsequent requests are fulfilled by the local Silver Peak instance.  
• Latency – Silver Peak mitigates latency enabling Telnet to operate more efficiently over distance.  TCP Acceleration includes windows scaling, selective acknowledgements, and HighSpeed TCP. Latency is also reduced through packet coalescing, which re-packages multiple smaller packets into a single larger one, and through Dynamic Path Control, which selects the fastest path to a remote location.
• Congestion – Silver Peak makes Telnet performance more predictable across congested WANs. Lost packets are reconstituted in real-time at the far end of a WAN link, avoiding delays that come with multiple round-trip retransmissions. Out-of-order packets are resequenced, avoiding retransmission and processing delays that occur when packets arrive out-of-order. Dynamic Path Control can select the path with the least loss to the destination.

Silver Peak protects Telnet data in-flight between locations with an Accelerated IPSec virtual private network (VPN) running AES-256, the enterprise standard for data encryption. Data-at-rest within Silver Peak instances is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.
