It is all too easy to think that when the network becomes increasingly sluggish, that an infrastructure upgrade is needed to maintain speeds acceptable to your users. More often than not, the problem is not that your users spend too much time downloading cat videos, but more likely that there are serious bottlenecks in the network that can and should be dealt with before bringing out the chequebook for new equipment. Consistent slowness in the network is difficult to pinpoint and sometimes more than one problem may be occurring at the same time. It is important to start looking at a few likely suspects.<\/p>\n
The all-too-obvious answer is to see bandwidth as the problem, but with investigation, it is often not within a LAN environment, where a high amount of bandwidth is available. More likely, the problem lies within the WAN, where capacity is more finite and expensive. Problems with slow networks in a WAN environment are more likely to result from not employing quality-of-service software, according to Jason Peach, principal consultant at Networks First. blem, using more intelligent analysis to optimise bandwidth is often a better way to solve a bandwidth contention the problem in any network scenario LAN, WAN or WLAN, for End-to-end latency (the delay that happens to a packet end to end from the PC to the server) and any errors causing re-transmission on the network will also degrade application performance and slow the network.<\/p>\n
Packet loss<\/strong><\/p>\n Poor network performance is characterised by packet loss, which can be measured in a number of ways by using a number of different tools. determined that packet loss is occurring, it is necessary to understand whether this is due to a lack of buffering when traffic bursts occur, a poor While on multiprotocol label switching (MPLS) networks, it is possible to prioritise important traffic, such as voice and video, over less important traffic such as web browsing and network backups. Meek says that even with IP QoS, it is still necessary to provision sufficient network bandwidth to avoid congestion. When networks collide Internet connections are increasingly becoming performance bottlenecks for organisations, mainly because of bandwidth that is not controlled properly, particularly with the increase in video streaming.<\/p>\n Bad planning<\/strong><\/p>\n Most network bottlenecks come about because of ineffective planning and forecasting and that this is a particular challenge when a wide variety of specialised, high-touch (Layer 3 to 7) equipment is deployed deep in the metro network.<\/p>\n From a network design standpoint, it is recommended to locate these functions in a small number of larger, metro\/regionally-centralised datacentres, and using low-cost-per-bit, efficient and easily reconfigurable packet-optical transport to aggregate and express the traffic between endusers and these content centres.<\/p>\n All hail the self-optimising network<\/strong><\/p>\n Network bottlenecks could become a thing of the past as embedded automation becomes part of the network. Joe This automation would provide more self-configuration, self-attachment, automated reconfiguration with adds, moves and changes of not just applications, but servers and other devices connecting into the network.<\/p>\n","protected":false},"excerpt":{"rendered":" It is all too easy to think that when the network becomes increasingly sluggish, that an infrastructure upgrade is needed to maintain speeds acceptable to your users.
