Network Monitoring

Converging all technologies onto a single network infrastructure is a much-debated subject, and many companies wish to develop a strategy to become a truly networked business.  Placing new demands on a shared network infrastructure sounds great, and the realities of this situation are that QoS must be carefully designed, planned and implemented.

Quality of Service is a key aspect of all modern networks.  Differentiating between mission-critical and trivial network traffic is widely supported both in the LAN and WAN on many vendor's equipment.  Classification of traffic is the first step in QoS, and is often the most difficult to implement.

Having the depth of expertise and understanding of QoS models and functions, Hinx can offer a multitude of advice on how to implement or how to improve QoS to provide the required level of service from the network infrastructure.

Our consultants can explain all of these terms in detail to enhance the understanding of your IT team, and your business.

Quality of Service means so many things to so many people, we aim to cover it all:

Ensuring that Voice traffic (and associated voice signalling traffic) is given priority over regular data traffic; both in the LAN and WAN - no-one likes "losing" part of a conversation because of "the network".

Whilst providing mission-critical applications with a guaranteed percentage of bandwidth on any link in the network;

Providing resilience plans that include a QoS provision - there is no point in having failover links that don't effectively operate your IP Telephony system.

Monitoring links - QoS relies on prioritising traffic, however bottlenecks can still occur and any QoS mechanism can be flooded with too much traffic of one type - causing starvation of other traffic types.  Being able to keep an eye on congestion and one queue lengths is a key metric in determining network health moving forward.  Hinx have developed Eagle-Eyes to include these valuable metrics to provide a health overview metric that incorporates trend information, and can alert the network manager when traffic levels depart significantly from the "normal" baselines.

Our expertise includes:

	QoS classification, marking, and re-marking
	Queueing mechanisms
	Congestion control mechanisms and discard schemes
	MPLS / DiffServe TE
	Queue Drop priorities (WRED)

Our multi-vendor expertise also shows how different vendors approach QoS, and how to get the best out of the particular vendor(s) in use in a network.
