Contradiction

I disagree with the initial definition. In networking since the early 80's, I've never heard the term "datagram" applied to the link layer by anyone with expertise in the field. "Datagram" refers to certain types of network layer packets (cf., Wikipedia entry for datagram ). The term "jumbogram" should be restricted to its IPv6 meaning, which is well-defined. Any other usage is colloquial and more likely to lead to confusion than to serve any useful purpose.

Furthemore, it's unnecessarily confusing. The phrase "exceeding the standard Maximum Transmission Unit (MTU)" is intended to mean, for example, an IP service data unit exceeding 64K bytes. But it's more likely to be interpreted by the typical reader as an IP service data unit that exceeds the Ethernet standard MTU of 1500 bytes of L2 payload.

Jumbo frame is used for link layer discussions. This is said in the second paragraph. I've edited to remove the contradiction. --Kvng (talk) 14:18, 16 December 2011 (UTC)[reply]

Does anybody use enormous packet sizes (>100 MB)? Backbone providers?

I just ran across a reference that IP6 could theoretically support a payload size of over 4 GB. ("Jumbo Frames: Does your network support Jumbo Frames and should you enable it?". Network World. Jun 3, 2013.) Does anyone know if the internet backbone companies use such enormous payloads (or even "moderately enormous" - i.e. "only" 128 MiB)? I'd imagine they might be useful for thinks like video streaming to a local cache, assuming the transmission line was very clean? Jimw338 (talk) 16:38, 24 December 2016 (UTC)[reply]
