	Hopcount - Wikipedia, the free encyclopedia
		It is a count of the number of routers an IP packet has to pass through in order to reach its destination.
		Hopcount is usually not used by itself, since any inbetween router or cable may have or be subject to varying data throughput (bandwidth), load (see: QoS), reliability (especially of cable), and latency.
		Hopcounts are often useful to find faults in a network (see: Time to live), or to discover if routing is indeed correct.

		The steps include placing cells of traffic are placed in a queue according to a hopcount associated with each cell of bursty traffic, the hopcount being representative of the number of nodes traversed by the associated cell.
		The hopcount associated with each cell of traffic is incremented as each cell of traffic is serviced.
		Although hopcounts are utilized only with bursty traffic and multicast traffic in the preferred embodiment, nothing prevents the use of hopcounts with other classes of traffic.

		Hopcounts serve a purpose similar to timestamps, but are more practical than timestamps at high speeds.
		A cell's hopcount indicates the number of nodes 22 previously traversed by the cell in its journey between source and destination.
		The cell hopcount is unaffected by moving between subqueues, permitting the hopcount to accurately represent the number of nodes 22 traversed by the cell.

	[SATLUG] Traceroute Result (Site not responding. Last check: 2007-10-20)
		When a packet's hopcount reaches zero, the router it is in sends back an ICMP unreachable packet to the originator and discards the packet.
		The packet goes through the first router, is decremented to one, and is dropped/unreachable'd by the second router.
		If all three timeout, it will increment the hopcount to the next higher number and send the three packets again.

	RIPE NCC
		There are two different approaches to compute the probability distribution function (pdf) of the hopcount of a path from A to B. Either we fix the topology and vary the source and destination over all possible couples or we choose a particular source and destination and let the topology change over all possible graphs.
		Since the influence of the correlation structure of this overlap on the hopcount is a priori difficult to estimate, in simulations and computation, the second approach had been followed.
		Thus, we demonstrate the applicability of that model in [1] to the Internet by illustrating that the distribution possesses the remarkable property of almost sure behaviour, which means that it features a high degree of robustness.

		This effect can be achieved by increasing the hopcount to 3, but this has the unfortunate effect that provider G would also receive prefix X. Thus, the AS hopcount is an extremely lightweight mechanism, and achieves a great deal of control.
		The AS Hopcount Attribute has a fixed length of 1 octet, which is an unsigned number that is the hopcount of the associated paths.
		This is a form of proxy aggregation and may result in routing behaviors that the origin of the path did not intend.

	Configuring the RIP Protocol
		RIP uses hopcount to determine the shortest path to a destination.
		Hopcount is the number of routers a packet must pass through to reach its destination.
		If the path passes through a single router, the hopcount increases to 2.

		Since the queue is not ordered by hopcount, it's very difficult to ensure the hopcounts are accurate.
		I don't know whether this has any influence on the particular bug mentioned, but suffice to say that fixing all the problems with hopcount in 3.1 is not going to happen--it would require backporting too much code.

		As Network Layer packets are processed, the information in their headers is used to update the NL table.
		The minimum observed hopcount to each (potential) remote destination is remembered by the NL table, as is the link on which these packets arrive.

		Or if you know that the hopcount will always be the last two characters you could use blaablaa35 and use a substring function to get it.
