    • It is proposed a method to operate a communication network, wherein a first node (A) is connected via a plurality of intermediate nodes with a second node (Z). A connection is associated with a first metric (202) and a second metric (204). It is determined a communication path (206) from the first node (A) to the second node (Z) along the intermediate nodes (B-K) by feeding results from a first optimization step regarding the first metric (202) to a second optimization step regarding the second metric (204) and feeding results from the second optimization step regarding the second metric (204) to the first optimization step regarding the first metric (202).

    • In order to measure the latency of a particular transport service from end to end, a method of measuring the latency of a transport connection between a first network node (NT) and a second network node (N2) is provided, which makes use of a virtual concatenation function with a buffer (B) to compensate the differential delay between members in a received virtual concatenation group. In particular, the first network node (NT) creates a virtual concatenation group which has as members at least two multiplexing units (VC4_1 VC4_2). A first of the two (VC4_1) is used as a reference for the latency measurement. The second (VC4_2) is sent to the second network node (N2), where it is looped back to said first network node (NT). The first network node (N1), by using its buffer (B) available for re-aligning members of a virtual concatenation group, determines a latency difference between the first and second multiplexing units (VC4_1, VC4_2).
    • 为了从一端到另一端测量特定传输服务的等待时间,提供了测量第一网络节点(NT)和第二网络节点(N2)之间的传输连接的等待时间的方法,其利用 虚拟级联功能与缓冲器(B)以补偿接收到的虚级联组中成员之间的差分延迟。 具体而言,第一网络节点(NT)创建具有至少两个复用单元(VC4_1 VC4_2)作为成员的虚拟级联组。 两个中的第一个(VC4_1)用作延迟测量的参考。 第二个(VC4_2)被发送到第二个网络节点(N2),在第二个网络节点(N2)处被环回到第一个网络节点(NT)。 第一网络节点(N1)通过使用其可用于重新对准虚拟级联组的成员的缓冲器(B)来确定第一和第二复用单元(VC4_1,VC4_2)之间的等待时间差。

    • It is proposed a method to operate a communication network, wherein a first node (A) is connected via a plurality of intermediate nodes (B-E) with a second node (Z). In a first determination step (222) an open path (224) starting with the first node (A) as a source node is determined. The open path (224) does not comprise the second node (Z) as a destination node. In a second determination step (226) a reaching path (228) starting with one of the intermediate nodes (C) in the open path (224) as a source node is determined. The reaching path (228) comprises the second node (Z) as a destination node.
