3. Internet Control Message Protocol - Wikipedia

   en.wikipedia.org/wiki/Internet_Control_Message...

   The traceroute command can be implemented by transmitting IP datagrams with specially set IP TTL header fields, and looking for ICMP time exceeded in transit and destination unreachable messages generated in response. The related ping utility is implemented using the ICMP echo request and echo reply messages.

4. Explicit Congestion Notification - Wikipedia

   Mac OS X 10.5 and 10.6 implement ECN support for TCP. It is controlled using the Boolean sysctl variables net.inet.tcp.ecn_negotiate_in and net.inet.tcp.ecn_initiate_out . [ 20 ] The first variable enables ECN on incoming connections that already have ECN flags set; the second one tries to initiate outgoing connections with ECN enabled.

   RFC 2474 — Definition of the differentiated services field (DS field) in the IPv4 and IPv6 headers. Note that the DS field of 8 bits (the bottom two unused) in [2] was later split into the current 6-bit DS field and a separate 2-bit ECN field. [3] RFC 2475 — An architecture for differentiated services. RFC 2597 — Assured forwarding PHB group.

7. Channel access method - Wikipedia

   en.wikipedia.org/wiki/Channel_access_method

   This requires a media access control (MAC) protocol, i.e. a principle for the nodes to take turns on the channel and to avoid collisions. Common examples are CSMA/CD , used in Ethernet bus networks and hub networks, and CSMA/CA , used in wireless networks such as IEEE 802.11 .

8. Contention (telecommunications) - Wikipedia

   en.wikipedia.org/wiki/Contention...

   Collisions are a condition that arises when two or more data stations attempt to transmit at the same time over a shared channel, or when two data stations attempt to transmit at the same time in a half duplex communication link. A contention-based channel access (multiple access) protocol is a protocol where data packet collisions may occur ...

9. PathPing - Wikipedia

   en.wikipedia.org/wiki/PathPing

   The advantages of PathPing over ping and traceroute are that each node is pinged as the result of a single command, and that the behavior of nodes is studied over an extended time period, rather than the default ping sample of four messages or default traceroute single route trace. The disadvantage is that it takes a total of 25 seconds per hop ...
