Description

通过IP封装的CCNx消息分段的切入转发
技术领域
本发明大体上涉及数据网络上的高效通信。更确切地说，本发明涉及使用IP封装的CCN消息分段的切入转发。
背景技术
互联网和电子商务的扩增持续形成大量的数字内容。内容中心网络(CCN)架构已经设计为有助于访问和处理此类数字内容。CCN包含实体或节点，例如，网络客户端、转发器(例如，路由器)，以及内容产生者，其通过传送用于各个内容项的“兴趣”包和继而接收“内容对象”包而彼此通信。CCN兴趣和内容对象通过它们的唯一的名称识别，所述唯一的名称是通常阶层结构的可变长度识别符(HSVLI)。通常，兴趣和内容对象在它们可以到达它们的目的地之前行进穿过多个链路。每个链路可以具有其自身的最大传输单元(MTU)，其中不同MTU限制施加不同分段要求。端到端CCN分段描述于以下申请案中：
2013年10月28日递交的标题为“用于具有阶层结构可变长度标识符的包的基于杂凑的转发的系统和方法(SYSTEM AND METHOD FOR HASH-BASED FORWARDING OF PACKETSWITH HIERARCHICALLY STRUCTURED VARIABLE-LENGTH IDENTIFIERS)”的第14/065,691号美国专利申请案(在下文中为“第14/065,691号美国专利申请案”)，发明人为Marc E.Mosko和Michael F.Plass；以及
2013年10月30日递交的标题为“用于内容中心网络中的最小路径MTU发现的系统和方法”的第14/067,587号(律师档案号PARC-20130874US01)美国专利申请案(在下文中为“第14/067,587号美国专利申请案”)，发明人为Marc E.Mosko。
在由CCN和互联网协议(IP)节点或路由器等转发装置组成的异构网络中，CCN内容段(在兴趣中请求的或在内容对象中接收到的)可以大于网络的最大传输单元(MTU)。一个解决方案是在网络层处使用IP并且依赖于IP分段。CCN消息(兴趣或内容对象)可以作为IP有效负载承载并且随着它逐段行进到下一CCN路由器通过当前已知的IP分段方法进行分段。CCN节点可以依赖于标准IPv4或IPv6协议堆栈以在每个CCN跃点处重新组装分段。然而，此解决方案引入延迟，因为CCN路由器需要等待所有IP分段到达以便重新组装整个CCN消息并且确定下一CCN跃点。此外，此解决方案引入额外延迟，因为在重新组装之后，IP包可能需要重新分段用于随后跨越网络行进。
发明内容
一个实施例提供促进网络上的消息分段的切入转发的系统。操作期间，系统接收对应于消息的分段并且含有分段标头的包。系统在数据结构中储存分段标头与阶层结构可变长度识别符(HSVLI)之间的映射关系，其中HSVLI包括从最常用层级到最特定层级的连续名称组分排序。系统在接收与消息相关联的所有分段包之前基于分段标头作出针对所述包的转发决策，由此促进网络上的消息分段的切入转发。
在一些实施例中，分段标头包含：指示分段对应于消息的流量识别符；指示对应于消息的分段的总数的分段计数；以及指示分段的指数的分段数目。
在一些实施例中，数据结构进一步包括对应于包含互联网协议(IP)源地址的元组的分段流识别符、IP目的地址、指示承载在IP包中的较高层协议的协议字段。以及指示分段对应于消息的流量识别符。
在一些实施例中，系统维持待定兴趣表(PIT)的指令，其中PIT中相应的项指示待决兴趣、流量识别符、识别兴趣并且对应于流量识别符的阶层结构可变长度识别符(HSVLI)，以及指示已经提供用于所述兴趣的多个对应的内容分段的分段位图列。
在一些实施例中，系统使用外部IP标头包封包以跨越混合网络传输包，其中混合网络包含与以下各项中的一或多个相关联的节点：内容中心网络(CCN)；运行IP的版本四的网络；以及运行IP的版本六的网络，由此促进使用网络上的IP封装的消息分段的切入转发。
在一些实施例中，包含有响应于内容中的兴趣的内容对象，其中基于分段标头中的相同流量识别符，含有内容对象的包的尺寸与对应于内容中的兴趣的最大分段相比在尺寸上是相等或更小的。
在一些实施例中，系统通过请求节点确定网络的最大传输单元(MTU)。系统将消息分段成一或多个包，其中每个包的所述小于或等于网络的MTU。系统生成识别对应于消息的一或多个包的分段标头。
在一些实施例中，系统生成对应于消息的HSVLI的流量识别符。此外，分段标头包含流量识别符、指示对应于消息的分段的总数的分段计数以及指示分段的指数的分段数目。

具体实施方式
呈现以下描述以使所属领域的技术人员能够制备并且使用实施例，并且在特定应用以及其要求的背景下提供以下描述。所属领域的技术人员将易于了解对所揭示的实施例的各种修改，并且在不脱离本发明的精神和范围的情况下，本文本所定义的一般原理可应用于其它实施例以及应用。因此，本发明不限于所示出的实施例，而是应符合与本文本所揭示的原理以及特征一致的最广范围。
概述
本发明的实施例提供使用由CCN和IP节点组成的异构网络中的IP封装促进CCN消息分段的切入转发的系统。在此类网络中，当CCN兴趣或内容对象消息大于底层网络的最大传输单元(MTU)时，网络提供分段服务，例如，IP分段。CCN消息作为IP包中的有效负载承载，其随后使用IP分段进行分段，并且从请求CCN节点发送到目的IP地址处的CCN节点。接收CCN节点可以使用标准IPv4或IPv6协议堆栈以在每个CCN跃点处重新组装分段。然而，此方法引发延迟因为：1)CCN节点需要等待所有的IP包分段到达以便重新组装CCN消息并且确定下一CCN跃点；以及2)在重新组装之后，CCN消息可能需要重新分段用于随后跨越网络的传输。
本发明解决了由于重新组装和重新分段的延迟和低效率的问题，方法是预先将CCN消息分段成与底层网络的MTU相同尺寸或更小的分段并且在每个消息分段的有效负载中包含分段标头。分段标头识别分段为属于CCN消息。操作期间，CCN节点发送与可以是CCN兴趣或内容对象的CCN消息相关联的第一分段，所述第一分段含有唯一地识别内容段的HSVLI以及分段标头。通过CCN节点发送的随后的分段含有相同CCN消息的部分和适当的分段标头，其指示对应于CCN消息的流量识别符、总分段计数和指数。分段传递到IP层并且通过适当的IP标头封装。
中间CCN节点接收第一分段、将流量识别符映射到HSVLI、更新其待决兴趣表(PIT)，并且通过将分段传递回IP层将分段转发到CCN数据路径中下一CCN跃点。当此中间CCN节点接收相同CCN消息的随后的分段时，它简单地检查流量识别符并且以与第一分段相同的方式将分段转发到下一CCN跃点而无需必须等待属于相同CCN消息的所有分段都在作出转发决策之前接收到。此系统因此促进通过底层IP封装的CCN消息分段的切入转发。
以下术语描述CCN架构的元素：
内容对象：单个命名数据段，其结合到唯一名称。内容对象是“持久性的”，这意味着内容对象可以在计算装置内来回移动，或跨越不同计算装置移动，但是并不发生变化。如果内容对象的任何组成部分发生变化，那么形成变化的实体产生包含更新内容的新内容对象，并且经由新密码编译签名将新内容对象结合到新唯一名称。
唯一名称：CCN中的名称通常是独立位置的并且唯一地识别内容对象。数据转发装置可使用名称或名称前缀朝向生成或储存内容对象的网络节点转发包，而无论所述内容对象的网络地址或物理位置如何。在一些实施例中，名称可以为阶层结构可变长度标识符(HSVLI)。HSVLI可划分成若干阶层组成部分，其可以不同方式构造。举例来说，个体名称组成部分parc、home、ccn及test.txt可以左向前缀为主方式(eft-oriented prefix-majorfashion)构造以形成名称“/parc/home/ccn/test.txt”。因此，名称“/parc/home/ccn”可为“/parc/home/ccn/test.txt”的“亲代(parent)”或“前缀”。额外组成部分可以用于区分内容项的不同版本，例如协作文档。
在一些实施例中，名称可包含非阶层式识别符，例如从内容对象的数据(例如，校验和值)和/或从内容对象的名称的元素导出的杂凑值。基于杂凑的名称描述于2013年3月20日递交的标题为“用于基于名称的包转发的有序元素命名(Ordered-Element Namingfor Name-Based Packet Forwarding)”的第13/847,814号美国专利申请案中，发明人为Ignacio Solis。名称还可以为平面标记(flat label)。下文中，“名称”用于指NDN中的数据段的任何名称，例如阶层名称或名称前缀、平面名称、固定长度名称、任意长度名称或标记(例如，多协议标记交换(MPLS)标记)。
兴趣：包，其指示对于数据段的请求，且包含所述数据段的名称(或名称前缀)。数据消费者可跨越信息中心网络散布请求或兴趣，CCN路由器可朝向可提供所请求数据以满足所述请求或兴趣的存储装置(例如，缓存服务器)或数据产生者传播所述请求或兴趣。
本文中所揭示的方法不限于CCN网络并且同样适用于其它架构。CCN架构的说明描述于2008年12月18日递交的标题为“在内容中心网络中控制兴趣和内容的传播(CONTROLLING THE SPREAD OF INTERESTS AND CONTENT IN A CONTENT CENTRICNETWORK)”的第12/338,175号美国专利申请案中，发明人为Van L.Jacobson和DianaK.Smetters。
示例性网络和通信
图1说明根据本发明的一个实施例促进网络上CCN消息分段的切入转发的示例性网络100。网络100可包含客户端装置116、内容产生装置118和路由器或节点102、104、106、108、110、112和114处的其它转发装置。网络100可以是异构网络，其中节点102-114中的每一个可以是CCN路由器或纯IP路由器。举例来说，节点102、108、112和114可以是CCN路由器，而节点104、106和110可以是纯IP路由器。CCN路由器可以是驻留在IP路由器顶上的CCN转发装置。换句话说，CCN可以实施为IP上的覆盖。其它CCN覆盖架构也是可能的。节点可以是计算机系统、终端表示用户和/或可以生成兴趣或产生内容的装置。举例来说，请求CCN节点102可以在内容段中生成兴趣；中间CCN路由器108和112可以接收和转发消息分段；以及CCN内容产生者114可以满足请求兴趣。节点102可以在内容段中生成兴趣；对所述兴趣消息预先分段；添加分段标头到每个分段，并且转发兴趣分段到中间CCN路由器108。CCN路由器108可以确定分段标头是否指示流量识别符与HSVLI之间的映射关系。如果映射存在，那么CCN路由器108将消息分段转发到下一CCN节点。底层IP层随后重新写入IP标头使得目的IP地址指向下一CCN节点。如果映射关系并不存在，那么CCN路由器108将流量识别符映射到HSVLI、更新其PIT，并且将兴趣分段转发到下一CCN跃点(例如，CCN路由器112)。相同过程发生在每个中间CCN路由器处直至消息分段到达可以产生内容或其高速缓存含有请求内容的节点(例如，产生者114)。
内容产生者114可以接收兴趣分段、预先分段请求的内容对象、添加分段标头到每个分段包，并且沿兴趣的反向路径转发回内容对象分段。CCN路由器112可以接收分段并且通过继续遵循兴趣的反向路径转发内容对象分段(例如，到CCN路由器108以及到请求节点102上)。请求节点102接收所有内容对象分段并且重新组装内容对象。
接收和转发兴趣分段
图2呈现根据本发明的一个实施例图示用于接收和转发指示内容段中的兴趣的包的方法的流程图200。操作期间，系统(例如，中间CCN路由器)接收对应于CCN消息的分段并且含有分段标头的包(操作202)。如果包含有足够的信息来识别CCN兴趣(例如，内容名称，例如，阶层结构可变长度识别符(HSVLI))(决策204)，那么接收节点确定内容是否已经存在于其高速缓存中(决策210)。如果确实如此，那么系统前进到图5中所描绘的操作。如果包不含唯一识别符(例如，HSVLI)，那么系统确定来自分段标头的流量识别符是否已经存在于本地数据结构中(决策206)。如果未在本地数据结构中发现流量识别符，那么这指示含有用于兴趣的唯一识别信息的第一分段尚未到达中间路由器。中间路由器可以缓冲分段并且继续接收和缓冲分段直至它接收含有识别信息的第一分段(操作208)。替代地，中间路由器可以丢弃包、发送通知消息到起始CCN节点，并且等待直至它接收相关分段(操作208)。
如果流量识别符存在于数据结构中(决策206)那么HSVLI与流量识别符之间的映射关系已经形成、指示含有HSVLI的分段已经通过中间路由器接收到。在这种情况下，系统执行兴趣消息分段的切入转发，方法是在接收与消息相关联的所有分段包之前将分段转发到CCN数据路径中的下一跃点(操作216)。中间CCN路由器通过将CCN分段传送到底层IP层转发分段，其基于下一跃点CCN节点处的IP地址重写IP标头。
如果接收到的分段确实含有HSVLI(决策204)并且内容并不驻留在中间路由器的高速缓存中(决策210)，那么中间路由器形成将流量识别符从分段标头映射到HSVLI的数据结构(操作212)。中间路由器更新待决兴趣表(PIT)，方法是添加对应于兴趣的项(操作214)并且通过针对CCN路由路径中的下一跃点重写外部IP标头转发分段。在一些实施例中，PIT包含兴趣分段位图列，所述位图列在每次对应的兴趣分段通过中间路由器接收到时更新。
接收和转发内容对象分段
图3呈现根据本发明的一个实施例图示用于接收和转发含有内容对象的包的方法的流程图300。中间CCN路由器接收对应于内容对象消息的分段并且含有分段标头的包(操作302)。中间路由器基于包含在内容对象消息分段的分段标头中的流量识别符检查相应的PIT项(操作304)。中间路由器还更新PIT中的分段位图列(操作306)，其储存指示是否已经接收到与内容对象相关联的所有分段位图(例如，64位长度的位图)。举例来说，基于来自用于特定的内容对象分段的分段标头的分段计数和分段指数，中间路由器可以在位图中用“0”更新适当的位以指示已经接收到分段。一旦分段位图中的所有位都是“0”，那么位图列“归零”(决策308)，指示中间路由器已经基于相同流量识别符接收到对应于消息的所有分段。中间路由器移除PIT项(操作310)以指示已经满足待决兴趣。最后，中间CCN路由器转发内容对象分段，方法是将CCN分段传送到底层IP层，其基于下一跃点CCN节点的IP地址重写IP标头(操作312)。
预先分段兴趣和生成分段标头
图4呈现根据本发明的一个实施例图示用于预先分段兴趣和生成分段标头的方法的流程图400。操作期间，系统(例如，内容请求节点)基于所确定的MTU确定网络的最大传输单元(MTU)(操作402)和预先分段消息，使得分段的尺寸低于或等于网络的MTU(操作404)。请求节点基于阶层结构可变长度识别符(HSVLI)生成流量识别符(操作406)。系统生成包含流量识别符、总分段计数和分段指数的分段标头(操作408)并且包含分段标头作为所有消息分段上的有效负载的一部分(操作410)。最后，请求节点发送消息分段到IP层，其生成用于CCN数据路径中的下一跃点CCN节点的IP标头(操作412)。
预先分段内容对象消息
图5呈现根据本发明的一个实施例图示用于通过预先分段内容对象满足内容段中的兴趣的流程图500。系统(例如，内容产生者节点)接收CCN兴趣消息的所有分段(操作502)，并且在确定内容产生者节点可以满足兴趣之后，使用接收到的分段和包含于分段标头中的信息(例如，分段的总数和每个分段的指数)重新组装兴趣消息(操作504)。作为回应，内容产生者节点将对应的内容对象分段成不超过最大接收到的兴趣分段的尺寸(操作506)。内容产生者节点生成包含流量识别符、总分段计数和分段指数的分段标头(操作508)并且包含分段标头作为所有内容对象分段上的有效负载的一部分(操作510)。最后，内容产生者节点通过将CCN分段传送到底层IP层转发内容对象分段，其基于下一跃点CCN节点的IP地址重写IP标头(操作512)。
消息分段和数据结构的示例性格式
图6A说明根据本发明的一个实施例用于促进网络上的消息分段的切入转发的CCN兴趣或兴趣分段600的示例性格式。分段600包含兴趣或兴趣分段614和分段标头618。分段标头618包含流量识别符608、分段计数610和分段数目612。兴趣或兴趣分段614含有CCN消息的一部分，并且分段标头618包含在每个CCN分段有效负载中以将分段识别为属于该CCN消息。流量识别符608是将分段识别为属于CCN消息的数目或共同标签。在一些实施例中，流量识别符608可以是随机生成的64位数目。流量识别符608还可以是基于HSVLI生成的基于杂凑的值、HSVLI的可路由的部分，和/或CCN消息的其它组分，如第4/067,587和第14/065,691号美国专利申请案中描述。分段计数610指示对应于CCN消息的分段的总数。分段数目612指示流内的分段的指数。IP标头616含有IP源地址602、IP目的地址604和协议字段606。其它已知的IP标头字段(未示出)也可以包含在IP标头616中。举例来说，在一些实施例中，IP标头616包含用于设定成“1”的“不分段”(DF)子字段的控制标志以指示IP包(在这种情况下承载预先分段的CCN消息分段614和分段标头618作为有效负载)不应该分段。
图6B说明根据本发明的一个实施例促进网络上的消息分段的切入转发的CCN内容对象或内容对象分段620的示例性格式。内容对象或内容对象分段620含有与图6A中的兴趣或兴趣分段600类似的字段。即，分段620包含内容对象或内容对象分段634和分段标头638。分段标头638包含流量识别符628、分段计数630和分段数目632。应注意与内容对象相关联的分段的尺寸和数目可以不同于接收到的且包含于对应的兴趣消息中的分段的尺寸和数目。举例来说，内容对象消息分段的尺寸可以不大于最大接收到的兴趣分段。此外，因为响应于接收到的兴趣的内容对象的总体尺寸可以大于接收到的兴趣，所以与内容对象分段流相关联的分段的数目可以大于与接收到的兴趣流相关联的分段的数目。如同图6A中的兴趣或兴趣分段600，分段620包含含有IP源地址622、IP目的地址624和协议字段626的IP标头636。
图7说明根据本发明的一个实施例通过系统保持以促进网络上的消息分段的切入转发的示例性数据结构700。数据结构700包含名称字段702，其描绘为阶层结构可变长度识别符(HSVLI)但是可包含本文所述的其它格式。数据结构700还可以包含流量识别符704，如关于图6A和6B中所描绘的分段标头的格式所描述。流量识别符704对应于HSVLI 702，使得含有相同流量识别符的消息分段对应于相同CCN消息。数据结构700还可以包含请求节点的IP源地址706、接收节点的IP目的地址708，以及用于运输包的协议710。在一些实施例中，用于运输IP包的较高层协议可以是传输控制协议(TCP)、用户数据报协议(UDP)或通用路由封装协议(GRE)。在一些实施例中，流量识别符704、IP源地址706、IP目的地址708和协议字段710一起形成来自IPv4包的元组。此元组包括可以是12字节字段的分段流ID。在一些实施例中，分段流ID可用于维持在PIT中的状态以指示特定的分段流的路径。举例来说，数据结构700的一个项可包含具有流量识别符824、IP源地址1.1.1.1、IP目的地址3.3.3.3和指示TCP的协议字段的“/wildlife/air/bird/finch”的HSVLI。
图8说明根据本发明的一个实施例通过系统保持以促进网络上的消息分段的切入转发的示例性待决兴趣表(PIT)800。PIT 800可包含描绘为阶层结构可变长度识别符(HSVLI)的名称字段802，但是其可包含本文所述的其它格式。PIT 800还可以包含兴趣进入端口字段804，其指示兴趣到达的端口对应于对应的内容对象应该发送出的端口。PIT 800还可以包含流量识别符字段806，如关于图6A和6B中所描绘的分段标头的格式所描述。流量识别符字段806对应于名称字段802，使得含有相同流量识别符的消息分段对应于相同CCN消息。PIT 800还可以包含分段位图列808，其储存指示是否已经接收到所有内容对象消息分段的位图(例如，64位长度位图)。在一些实施例中，PIT 800可包含兴趣分段位图列(未示出)，其储存指示是否所有的兴趣消息分段已经被接收到的位图。系统可以使用此位图，结合时间到实时(TTL)字段或其它超时或过期字段以确定是否在PIT 800中移除不完整项。系统可以出于未在本文中列举的其它目的进一步使用兴趣分段位图列。
示例性计算机及通信系统
图9说明促进网络上的消息分段的切入转发的示例性计算机及通信系统902。计算机及通信系统902包含处理器904、存储器906和存储装置908。存储器906可包含易失性存储器(例如，RAM)，所述易失性存储器充当管理存储器并且可用于储存一或多个内存池。此外，计算机及通信系统902可以耦接到显示装置910、键盘912和指向装置914。存储装置908可以储存操作系统916、内容处理系统918和数据932。
内容处理系统918可包含指令，当通过计算机及通信系统902执行所述指令时可以使得计算机及通信系统902执行本发明中描述的方法和/或过程。具体来说，内容处理系统918可以包含用于接收对应于消息的分段并且含有分段标头的包的指令(通信机构920)。内容处理系统918还可以包含用于在接收与消息相关联的所有分段之前基于分段标头作出针对包的转发决策的指令(转发机构928)。
