The term C10k was coined in 1999 by software engineer Dan Kegel, [3] [4] citing the Simtel FTP host, cdrom.com, serving 10,000 clients at once over 1 gigabit per second Ethernet in that year. [1] The term has since been used for the general issue of large number of clients, with similar numeronyms for larger number of connections, most recently ...
Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255 1 048 576: Private network Used for local communications within a private network [3] 192.0.0.0/24 192.0.0.0–192.0.0.255 256
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [ 1 ] [ 2 ] IP addresses serve two main functions: network interface identification , and location addressing .
For IPv4, no black hole address is explicitly defined, however the reserved IP addresses can help achieve a similar effect. For example, 198.51.100.0 / 24 is reserved for use in documentation and examples [ 2 ] ; while the RFC advises that the addresses in this range are not routed, this is not a requirement.
The data link layer addresses data packets based on the destination hardware's physical Media Access Control (MAC) address. Switches within the network maintain Content Address Tables (CAMs) that maps the switch's ports to specific MAC addresses. These tables allow the switch to securely deliver the packet to its intended physical address only.
Designed to provide rapid network redundancy, on top of spanning tree protocol. [3] Each node is connected twice to a single LAN through the dual network interface controllers . The driver and the FTE enabled components allow network communication to occur over an alternate path when the primary path fails.
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
