"为什么DIY报价-networking all-in-one for dummies 6th 2016第6版 无水印pdf 0分" 本文主要探讨的是软件开发行业的成本估算和DIY报价策略,尤其针对小型软件作坊如何转型为正规军。作者通过一系列文章讨论了开发、实施和服务费用的计算,旨在帮助小型团队更好地理解和控制项目成本。 在《为什么DIY报价》这一章节中,作者指出,DIY报价对于软件公司来说是一种自我提升和市场竞争力增强的方式。他回应了一位网友的观点,该网友认为在竞争激烈的市场环境下,报价可能受到市场供需关系的影响,而无法完全由企业自身决定。然而,作者强调,作为商业软件公司,其目标是通过更高效的工作方式赚取更多的利润,因此,选择工具、技术和管理方法时,必须考虑它们是否能降低成本、提高效率。 作者提到,他们不愿意采用那些不能带来工作量减少或利润增加的方法。同时,他还提到了DIY实施费用和服务费用的重要性,这意味着企业需要对自身的成本结构有深入的理解,以便在竞标时提供更具竞争力的价格,同时确保项目的可持续性。 书中的其他章节涵盖了多个主题,如技术总监与CTO的角色区别、项目经理的管理工具、人力资源管理、实施经理和客服顾问的角色、销售策略、项目管理和文档编制等。这些内容都是软件公司成长和规范化过程中不可或缺的知识点,有助于企业提高运营效率,优化成本,并在市场中找到合适的位置。 此外,书中还涉及了公司战略、产品开发与市场销售的关联,以及如何将技术优势转化为业务增长。作者强调CTO不仅要在技术层面发挥作用,还需要关注产品与公司战略的契合,以推动整体业务的发展。 这本书为软件开发从业者提供了一套全面的指导,涵盖了从组织架构到项目执行的多个层面,旨在帮助小团队实现专业化和商业化转型。通过学习和实践其中的理念,软件开发者和管理者可以更好地掌握成本控制,提高服务质量,从而在竞争激烈的市场环境中立于不败之地。

翻译 There are several reasons a network designed on layer-2 protocols is selected over a network designed on layer-3 protocols. In spite of the difficulties of using a bridge to perform the network role of a router, many vendors, customers, and service providers choose to use Ethernet in as many parts of their networks as possible. The benefits of selecting a layer-2 design are: Ethernet frames contain all the essentials for networking. These include, but are not limited to, globally unique source addresses, globally unique destination addresses, and error control. Ethernet frames can carry any kind of packet. Networking at layer-2 is independent of the layer-3 protocol. Adding more layers to the Ethernet frame only slows the networking process down. This is known as nodal processing delay. You can add adjunct networking features, for example class of service (CoS) or multicasting, to Ethernet as readily as IP networks. VLANs are an easy mechanism for isolating networks. Most information starts and ends inside Ethernet frames. Today this applies to data, voice, and video. The concept is that the network will benefit more from the advantages of Ethernet if the transfer of information from a source to a destination is in the form of Ethernet frames. Although it is not a substitute for IP networking, networking at layer-2 can be a powerful adjunct to IP networking. Layer-2 Ethernet usage has additional benefits over layer-3 IP network usage: Speed Reduced overhead of the IP hierarchy. No need to keep track of address configuration as systems move around. Whereas the simplicity of layer-2 protocols might work well in a data center with hundreds of physical machines, cloud data centers have the additional burden of needing to keep track of all virtual machine addresses and networks. In these data centers, it is not uncommon for one physical node to support 30-40 instances.
