Talk:Netflow

From Wikipedia, the free encyclopedia

a quote said that v5 was most common "next to" v9 meaning that v9 was more common, but the table on the page says v5 is most common and I would tend to agree

What the heck does "open but proprietary" even *mean*? Those two words are antonyms in a software context. I suggest either an explanation of what is meant or a revision. (I lean towards revision).

[edit] Software directory

Directories of software in articles of this nature is outside WP:EL guidelines. I've removed the list and suggest that if anyone feels there is a burning need for an external link to a specific piece of software, raise it in this talk page first to allow others to comment, else you may be reverted. -- Moondyne 13:09, 18 October 2006 (UTC)

If software links are to be removed, they should be removed from the "see also" section too. i.e. Calgiare Flow Inspector, PRTG and MRTG. MRTG doesn't even use netflow? Or is there something I'm missing here? Pleamon 17:25, 9 February 2007 (UTC)

[edit] incorrect terminology

In section Netflow Record, it is said that the record contains L3 headers and a list of the items contained in that header is given:

  1. Layer 3 headers:
   * Source & destination IP addresses
   * Source and destination port numbers
   * IP protocol
   * Type of Service (ToS) value

src and dst ports are NOT part of l3 header but l4 header. this brings to the paragraph which is just above which says :In the case of NetFlow, Cisco uses the common 5-tuple definition, where a flow is defined as a unidirectional sequence of packets all sharing all of the following 5 values:

  1. Source IP address
  2. Destination IP address
  3. Source TCP port
  4. Destination TCP port
  5. IP protocol

I'm not very familiar with netflow but if src and dst ports are part of what defines a flow, does this mean that netflow supports only ip protocols 6 and 17 (tcp and udp) because the other ones (ex. gre, esp,ip-in-ip etc) DO NOT have port numbers and thus do not qualify to form a tuple.Strangeusername 08:01, 23 August 2007 (UTC)

[edit] Supported Platforms

To clarify the availability of NetFlow technology, it should be stated that it is only available on the routers and modular switches within Cisco product line (NetFlow Availability). Some of the other products also includes necessary command set but not effective and this confuse the community. MustafaAksu 20:01, 12 September 2007 (UTC)
