Co-Packaged Optics Maximum Rate Allocation Algorithm, Marco Mazzini, Alberto Cervasio

Defensive Publications Series

With the introduction of co-packaged optics (CPO)-based hosts, systems can be designed in a manner that is more flexible than conventional systems. It is possible to view the CPO as an electro-optical matrix rather than a battery of pluggable modules as with conventional hosts. Such an approach provides the opportunity to design CPO-based switches for flexibility, protection, and resilience up to 102.4 Terabits or beyond. Pluggable solutions, in addition to being more expensive, may not have such capabilities. Leveraging such opportunities, this proposal provides new techniques for defining the connectivity between CPO hosts in a manner that allows for maximum …

Preserving Manual Modifications To Auto-Generated Code Across Versions, Patrick Blesi

Defensive Publications Series

When an automatic code generator updates code that has been manually modified, the manual edits get overwritten and effectively lost. This is a problem for test and development engineers.

Optimized Multi-Homing In Inter-As Option B For Ethernet Virtual Private Networks, Satya Mohanty, Mankamana Mishra, Ali Sajassi

Defensive Publications Series

It is becoming increasingly common to stretch Ethernet Virtual Private Network (EVPN) services across Inter-Autonomous System (Inter-AS) boundaries. In such Inter-AS deployments, providers do not like to expose loopbacks of a provider edge (PE) router's loopbacks in one AS to the other AS, since this typically ensures less maintenance overhead and also allays security concerns. Inter-AS Option B for EVPN is ideally suited for such deployments as the next-hops of the EVPN routes for Inter-AS Option B are reset at the AS Border Router (ASBR), so the receiving AS does not know the loopback addresses of an advertising AS. This …
