Routing with variant configuration?

Indeed,this especially occurs in typical pipe routing with that closed vertically bent down branch followed by a horizontal line.

向国外银行提款的时候,发现单子上要填：sorting or routing number.后面还有一小句注释：if applicable.Contact your bank officer if unusure.这句注释看得懂,就是不明白要我填写的sorting or routing number究竟是什么?前面已经填过银行Swift码了啊.请懂金融又懂外语的高手帮忙翻译下,

no detailed maps found that support routing.the nuvi cannot be used without them
那怎么弄才行呢？

Abstract
The routing of vehicles and the management of logistics operations in any company that services a fairly large geographical area can easily become quite a very complex task.The task can be simplified by the applying Geographic Information Systems,which automatically reduce the complexity by bringing out subtle geographic patterns and relationships that can form the basis of good decisions.Systems like ArcLogistics Route can take pain out of applications like Vehicle Tracking and Dispatch,Route Analysis,Warehouse Operations,Facilities and Depot Management,Routing and Scheduling.The ease of work has to be looked at though in the light that all of the data required for maximum accuracy may not be available.The system's potential would suggest that reasonably accurate decisions can still be arrived at with less that complete data sets and in time,India too would grow into a mature GIS market where data would not longer be a constraint.

急用,别人给我的一段文字,大家如果愿意帮我翻译一下：
Differential Pair Routing:
- Each signal trace routed between the device and the RJ45 should have a characteristic differential impedance of 100 ohms +/- 10%
- The space between on TRD+/- trace pair and another from a comon port should be at lease 3X the trace height
- Route differential pairs so that the TRD+ and TRD- signals are closely spaced.Do not use serpentines to make the trace lengths match.Route pairs without changing layer(s) as much as possible
- Identify all high bandwidth signals and their return paths
- Do not route signals accross the moat

A natural extension to Onion Routing is the introduction of reply onions.Reply onions allow connections to be made back to an anonymous sender through the Onion Routing network long after the original connection existed.Reply Onions could be used to send anonymous replies in response to a previously received anonymous email.They could also enable novel applications such as anonymous publishing (anonymous URLs) similar to the Rewebber project

With the development of internet,technology of routing has been studied by more and more researcher.Routing is a fundamental problem in communication networks.In traditional data networks,routing is achieved by best effort routing.Best effort routing is primarily concerned with providing connectivity.FIFO provides best-effort service.Here,flows are not differentiated and are serviced on a first-come,first-served basis.In best effort routing,the routing protocol usually characterizes the network with a single metric,such as hop-count or delay,and uses a shortest path algorithm for path computation.Whereas the best-effort routing paradigm is adequate to serve the needs for traditional applications such as FTP (File Transfer Protocol),it is quite inadequate in providing the stringent Quality of Service (QoS) guarantees demanded by popular multimedia applications such as real-time digital video or audio transmission.To support a broad range of QoS requirements,routing protocols need to consider more complex models that incorporate multiple metrics,such as cost,delay,delay variation,loss probability,and bandwidth.This has triggered efforts toward proposals for QoS-based frameworks,QoS routing protocols and QoS routing algorithms.
Despite these efforts,there is no standardized QoS routing protocol for the Internet.To the best of our knowledge,the only standardized QoS routing protocol is ATM PNNI [1].Two activities are involved in routing:1) Capturing the network state information and disseminating the information throughout the network.This requires detection of significant changes,topology updates,distributed broadcasting (flooding) of the information to each node in the network,etc.2) Routing algorithms that compute the paths that satisfy certain performance guarantees.
In this paper,we are concerned with the latter,namely,QoS routing algorithms.QoS measures can be classified into three types of metrics,minimal (also called bottleneck,e.g.,bandwidth),multiple (e.g.,loss probability) and additive constraints (e.g.,delay).
Each measure is modeled by associating a weight with each link.For a minimal measure,the QoS weight of a path is the minimum weight along the path.In the case of additive measures such as cost,delay,and delay-jitter,the QoS weight of a path is the sum of the QoS weights of the links on the path.And for a multiple measure,the QoS weight of a path is the accumulation of the QoS weights of the links on the path.
In this paper,we are only concerned with one delay constraint and one loss probability constraint,and not concerned with the minimal measures.There are two reasons:
