Methods of steering traffic into MPLS and Segment Routing LSP is one of the least standardized and most confusing parts of traffic engineering.…
Despite many advantages of Segment Routing, some networks still prefer to use RSVP for traffic engineering – and they can have good reasons for this. Is there any value of SDN controller with RSVP-TE, compared to configuring policies on each …
Segment Routing was supposed to make MPLS easier and give more power to network operators. Sadly, vendors decided to make it harder by selling weird protocols and over-engineered controller bloatware.…
MPLS is such a user-friendly technology it needs a special label that does nothing.
…
My recent post about Anycast in Segment Routing led to an interesting argument on whether other MPLS transport protocols can do anycast routing.…
MPLS or Anycast Routing – for a long time, you had to choose one. Segment Routing allows you to have both.…
In any L2 overlay network, ARP handling will always remain a big pain for network operators.…
Instability of routing protocol sessions – or, in the network engineers’ slang, flaps, is by far the most common and the most basic routing problem that ever occurs.
…
In highload cloud networks there is so much traffic that even 100G/400G port speeds do not suffice, so sharing the load over multiple links is the only feasible solution.
…
For any network that provides routing services to customers it is important to segregate them in different virtual topologies that don’t interfere with each other.
