Sample text

Quality of service (QoS) is an integral set of features in a service router, essential for satisfying diverse service needs of different application traffic, while maximizing the resource utilization of the router within a multi-service network. This book introduces you to the fundamentals of QoS for an Internet Protocol/ Multi Protocol Label Switching (IP/MPLS) network. It also addresses the theoretical and practical details of advanced QoS features offered by service routers, and concludes by teaching you how to design QoS in a multi-service network.

Fragment Offset—The 13-bit Fragment Offset field indicates the position of the payload to the beginning of the original unfragmented data segment. The fragment offset is expressed in terms of 64 bits or 8 octets. The offset of the first fragment is zero. • TTL—The 8-bit time to live field indicates the upper bound of time the packet is allowed to exist. • Protocol—The 8-bit Protocol field indicates the upper-layer protocol to which the packet belongs. The protocols are indicated by their Assigned Internet Protocol Numbers.

Delay RFC 2679 defines a metric for measuring one-way delay as the difference in the time at which the datagram crosses two reference points. The delay of a datagram experienced within a service provider network is defined as the difference in the time at which the datagram enters the network and the time at which it leaves the network. Delay is also commonly referred to as latency. Each element through which a datagram flows in a traffic path will increase the delay experienced by the datagram. 1, links L1 and L3 will impose a propagation delay, and the node N1 will impose a processing delay to the traffic flowing through them.
