The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 Gigabit/s) Local area network using existing home wiring (power lines, phone lines and coaxial cables), is an example of a protocol that employs packet aggregation to increase efficiency.
A LAG is a method of inverse multiplexing over multiple Ethernet links, thereby increasing bandwidth and providing redundancy. It is defined by the IEEE 802.1AX-2008 standard, which states, "Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group, such that a MAC client can treat the Link Aggregation Group as if it were a single link."
Link aggregation between a switch and a server In computer networking , link aggregation is the combining ( aggregating ) of multiple network connections in parallel by any of several methods. Link aggregation increases total throughput beyond what a single connection could sustain, and provides redundancy where all but one of the physical ...
The loss of packet flow samples results in a slight reduction of the effective sampling rate. The UDP payload contains the sFlow datagram . Each datagram provides information about the sFlow version, the originating device’s IP address , a sequence number, the number of samples it contains and one or more flow and/or counter samples.
For example, IP uses IPCP, and Internetwork Packet Exchange (IPX) uses the Novell IPX Control Protocol . NCPs include fields containing standardized codes to indicate the network layer protocol type that the PPP connection encapsulates. The following NCPs may be used with PPP: IPCP for IP, protocol code number 0x8021, RFC 1332
Therefore, no single flow can exceed the speed of a physical port. However, some PagP-enabled switches can negotiate between a "maximize load balancing" and "preserve ordering" link: the former give maximum aggregated bandwidth at the expense of packet ordering, while the latter assures no packet reordering to occur but limit a single transfer ...
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.
Equal-cost multi-path routing (ECMP) is a routing strategy where packet forwarding to a single destination can occur over multiple best paths with equal routing priority. Multi-path routing can be used in conjunction with most routing protocols because it is a per-hop local decision made independently at each router.
