Abstract: In one aspect, the disclosure relates to azide-containing poly(ether imide) polymers (PEIs; N3-PEI-N3) synthesized via a heterogenous diazotizationazidation reaction. In one aspect, the azide-containing PEIs can be solution-cast into films and then thermally crosslinked. In a further aspect, the crosslinked PEIs (X-PEIs) exhibit superior thermal and mechanical properties. In a still further aspect, X-PEIs display outstanding resistance to classical solvents for conventional PEI, including THF, DCM, chloroform, DMF, and NMP. In another aspect, with an initial number average molecular weight (Mn) of 8.9 kDa, the disclosed azide-containing PEIs have a high crosslinking density and thus possess desirable thermal, mechanical, and solvent resistance properties.

Abstract: A first provider edge (PE) determines whether a link between the first PE and a second PE is a high latency link, where the second PE is a next hop of the first PE. When determining an actual latency corresponding to the link, the first PE compares the actual latency with a first latency threshold. When the actual latency is greater than or equal to the first latency threshold, it indicates that the actual latency exceeds a latency upper limit corresponding to the link, the first PE determines that the link is a high latency link. In this way, it is not necessary to wait for network management personnel to determine whether the link is a high latency link. After determining the actual latency corresponding to the link, the first PE can determine in time whether the link is a high latency link.

Abstract: Embodiments relate to a routing information processing method and apparatus. The method implemented by a first network device includes: obtaining a local route corresponding to a second network device, where the local route includes a first identifier; allocating a first segment identifier based on the fact that the first identifier exists only in the local route; obtaining a local route and a remote route that correspond to a third network device, where each of the local route and the remote route includes a second identifier; allocating a second segment identifier based on the fact that the second identifier exists at least in the local route and the remote route; and sending routing information including the first segment identifier and the second segment identifier. This avoids traffic interruption of a failure-free single-homed network device in a scenario in which single-homing and multi-homing coexist.
