hop count


Also found in: Dictionary, Thesaurus, Medical, Wikipedia.

hop count

The number of point-to-point links in a transmission path. Since each link is terminated at a network device such as a router or gateway, the processing performed within the device to determine how to forward the packet adds overhead to the transmission. Although each point-to-point link is technically a hop, the hop count is the number of network devices between the starting node and the destination node. An IP packet traveling over the Internet can easily "hop" through more than a dozen routers.


Hops in a Network
Electrical signals may travel near the speed of light in a wire, but each junction point (router, gateway, etc.) adds processing overhead.

The average hop count per minimum hop path determined for the two VANET mobility models and the Gauss-Markov model is considerably larger than the hop count per minimum hop path determined for the Random Waypoint mobility model.
The intermediate node then forwards the RREQ packet by incrementing the hop count of the path from the source node.
To ensure the selection of the shortest path, we propose a new scheme in which an intermediate node, replies each time it receive a RREQ with hop count less than the one previously processed.
R-MLPBR has been thus designed to also reduce the number of links that form the multicast tree, in addition to the source-receiver hop count and the number of global tree discoveries.
Every RREQ packet carries the source and destination addresses, a sequence number, hop count, delay parameter (max_delay) and Accumulated Value extension (acc_delay).
As part of its AURP support, Wellfleet offers a Hop Count Reduction capability to overcome the AppleTalk 15 hop limitation, allowing users to expand their AppleTalk networks.
Internet Service Providers and Backbones for Delivery Center placement are selected based on performance testing which InterVU regularly conducts to measure download time, hop count, and network reliability.
Key features include, route-around link failure, extended source route bridging hop count, reduced WAN overhead through local data link termination (SDLC-LLC2), and NetBIOS name caching.
Virtual HyperIP mitigates TCP performance issues that are common when moving stored data over wide area network connections because of bandwidth restrictions, latency due to distance and/or router hop counts, packet loss and network errors.
Compared to the distance-based approach, direction-based plans intend to acquire a path with shorter end-to-end distance; nevertheless, more hop counts is likely to be needed.
Service providers benefit from reduced hop counts and bandwidth savings across the network while their subscribers enjoy faster download times.
HyperIP mitigates TCP performance issues that are common when moving data over WAN connections because of bandwidth restrictions, latency due to distance and/or router hop counts, packet loss and network errors with application acceleration and Data Transport Optimization for remote data replication and large file transfer requirements.
