Yang (2010) provided an algorithm to determine the optimal order quantity, the length of lead time and the number of lots which are delivered from the supplier to the buyer to minimize expected total cost over infinite time horizon.

EtherChannel bundles multiple physical Ethernet links (100 Mbps,1 Gbps, 10 Gbps) into a single logical link. Traffic is distributed across multiple physical links as one logical link. This logical link is represented in Cisco IOS syntax as a 'Port-channel' (Po) interface. STP and routing protocols interact with this single port-channel interface. Packets and frames are routed or switched to the port-channel interface.


A certain balance loading mechanism is used to determine which physical link will be used to transmit them.

  1. 4.1 BACKGROUND AND MOTIVATION Rate adaptation is a link layer mechanism to maximise the throughput in IEEE 802.11 based wireless networks. IEEE standard supplements 802.11a and 802.11b do not specify any algorithm for automatic rate selection. Limited spectrum and noisy channel are the key problems in wireless communication. The IEEE standard defines several MAC level.
  2. On Performance of HFC MAC Layer Algorithms. A thesis submitted in fulfillment. An optimal frame size was found, and we suggest algorithms that, when run at the head-end, adjust the frame size dynamically and keep it close to. Chapter 7 deals with request access delay jitter and with the way it changes with distance.

Book Description This book covers the design and optimization of computer networks applying a rigorous optimization methodology, applicable to any network technology. It is organized into two parts. In Part 1 the reader will learn how to model network problems appearing in computer networks as optimization programs, and use optimization theory to give insights on them. Four problem types are addressed systematically – traffic routing, capacity dimensioning, congestion control and topology design. Part 2 targets the design of algorithms that solve network problems like the ones modeled in Part 1. Two main approaches are addressed – gradient-like algorithms inspiring distributed network protocols that dynamically adapt to the network, or cross-layer schemes that coordinate the cooperation among protocols; and those focusing on the design of heuristic algorithms for long term static network design and planning problems. Following a hands-on approach, the reader will have access to a large set of examples in real-life technologies like IP, wireless and optical networks.

Implementations of models and algorithms will be available in the open-source Net2Plan tool from which the user will be able to see how the lessons learned take real form in algorithms, and reuse or execute them to obtain numerical solutions. An accompanying link to the author’s own Net2plan software enables readers to produce numerical solutions to a multitude of real-life problems in computer networks.
