5. Analyze the traffic patterns ­ Locate busy segments and why those segments are busy and develop plans to mitigate them going RE: Data Link Layer Mini­case Zachariah Westerfield 9/10/2016 1:21:2 Typical causes for network bottlenecks are an overloaded server, an overloaded network, or a loss of network integrity. The following tec can help to address some of these problems. If communicating over Token Ring, FDDI or switched Ethernet networks, attempt to balance network traffic by distributing client con across multiple network adapters. When using multiple network adapters, make sure that the network adapters are distributed among t buses. For example, if you have four network adapters with three PCI buses, one 64­bit and two 32­bit, allocate two network adapters t bus and one adapter to each 32­bit bus. Splitting the adapters across multiple Ethernet segments is an effective way to eliminate an ov network if the physical environment is switched Ethernet, and all adapters are on the same physical segment. For more information abo network adapters, see "Adding Network Adapters" later in this chapter. Use adapters with the highest bandwidth available for best performance. Note that increasing bandwidth increases the number of tra that are taking place and in turn makes more work for your system, including more interrupts being generated. Remove unused networ to reduce overhead. Use adapters that support task offloading capabilities (checksum offloading, IPSEC offloading, and large send offloading). If your network uses multiple protocols, place each protocol on a different adapter. Make sure to use the most efficient protocols, espe that minimize broadcasts. Notice that reducing the number of protocols installed can increase performance. High rates of interrupts from network adapters can reduce performance. Using network adapters that batch interrupts by means of in moderation can improve this performance problem, provided the adapter driver supports this capability. Another option is to bind interru from network adapters to a particular processor to improve performance. When using Interrupt Filter to bind a network adapter to a set processors. For more information about processor affinity and Interrupt Filter, see "Measuring Multiprocessor System Activity" in this bo more information about Interrupt Filter, see online Help on the Windows 2000 Resource Kit companion CD. Divide your network into multiple subnets or segments, attaching the server to each segment with a separate adapter. This reduces at the server by spreading server requests. Although binding order is relevant on the client computer, there is no reason to reorder server bindings because the server accepts in connections based on the protocol used by the client computer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
