But do you know what the consequences of using Frame Relay are and in what scenarios it is good to use it?
Is the key to Frame Relay the utilization of existing telephone wires and infrastructure? After reading this page I fail to grasp the principal reason for its existence.
It would be nice if someone included an image or a table layout of what the Frame Relay header/protocol looks like. Having a text only description of the header makes undestanding or even just imagining it quite hard. The type of switching used for frame relay should be included here.

This article needs a basic description of the technology upfront. For those with low to medium knowledge needing a basic techincal description, there is no jumping-off point. A good, basic description of how it works and how it varies from other models would help clarify. —Preceding unsigned comment added by 216.68.204.87 ( talk) 02:29, 14 October 2007 (UTC)
The X.25 standard was upgraded in 1992 to accomodate 2 Mbps speeds. If FR is 20 times faster, where is the info that says FR is available at 80 Mbps?-- itpastorn ( talk) 09:09, 28 February 2008 (UTC)
I heard Frame Relay mentioned as the "Poor man's ATM". Is that assertion practically correct? 82.131.210.162 ( talk) 10:53, 23 May 2008 (UTC)
This article needs help. Frame relay is quite important.-- MrBobla ( talk) 13:30, 14 December 2008 (UTC)
Frame relay is a the y un substitutional relay to the one hop to another hop for substinated by he naturale atomicaly sercumtances to delivered of send the data packets any instance.this should be prefered to managed of atomicaly undeclorated of that time prefered by the frame relay process.
My recollection from the time is that AT&T and Sprint and others were offering proprietary modifications to X.25. The modifications were not so involved with throwing away error correction as in removing the hop-by-hop store-and-forward nature of X.25 that mostly impacted performance. These proprietary networks (I believe AT&T's version was called Accunet) performed end-to-end acknowledgement rather than hop-by-hop store-and-forward acknowledgement increasing the performance of network switches dramatically. As I recall, the standardization effort was primarily to provide a common basis for these and other advances over X.25 (such as dynamic multiplexing with fast-packet techologies). Fast-packet technologies went further than reducing the cost of hop-by-hop store-and-forward, which basically removed layer 3 and half of layer 2 at interior switches, by having the terminating switch simply discard errors. However, this was not due to the high cost of requesting end-to-end retransmissions, but rather because ISDN clear-channel requirements had increased the accuracy of networks from 10E-03 to 10E-05 or 10E-06, meaning that retransmissions were seldom required anyway. (I don't think that one can really call this best-effort, particularly as the term is used in Internet Protocol routers.) Although I am sure that AT&T and Sprint and others patented their is a un substitu individual approaches, I don't know that Sprint was first or could be attributed with "inventing" frame relay. Recent changes to the article including such claims need to be substantiated with proper references. Also, I have references that indicate that Sprint was late out of the chute in deploying frame-relay, even though Nortel (a major supplier of Sprint at the time) was offering it on their DMS SuperNodes earlier. —

What is the contextual meaning of the word 'loom' in this sentence from the article?: "the end may loom for the frame relay protocol and encapsulation". From dictionary.com the verb definition of loom says this: "to appear indistinctly; come into view in indistinct and enlarged form". ( http://dictionary.reference.com/browse/loom?s=t). Would the referenced article sentence using loom be correct if written as follows?: "the end may [appear indistinctly] for the frame relay protocol and encapsulation". Thanks in advance for clarification. — Preceding unsigned comment added by Dbudge1 ( talk • contribs) 21:32, 11 April 2015 (UTC

Oppose. Delete instead. User:Kvng has proposed merging FRF.12 into this article, removing the WP:PROD placed there by User:Piotrus. However, there is nothing to merge. The FRF.12 article has no sources and is obviously original research. We don't merge content that is not according to policy. Delete FRF.12. — Prhart com♥ 23:07, 16 June 2016 (UTC)
Thanks Prhartcom for performing the merge. I'm not sure why you also nominated FRF.12 for deletion though. ~ Kvng ( talk) 14:49, 19 June 2016 (UTC)
This sentence is not true for the UK at least, probably not any of Europe as far as I know: "However many rural areas remain lacking DSL and cable modem services. In such cases, the least expensive type of non-dial-up connection remains a 64-kbit/s Frame Relay line."
AFAICT, Frame Relay doesn't define the physical layers, only data link layer. However, the article says that F.R. operates on Layer 1 and 2 (physical and data link).
Perhaps some mention of where F.R. defines the physical layers, otherwise best just to say it operates on layer 2 only (Data Link). Chris Fletcher ( talk) 05:07, 17 February 2019 (UTC)
