Container lsp
In the first part of the article I tried to describe the capabilities of some approaches to balancing traffic in the MPLS domain, the idea was to show the unique hardware requirements for the chip, which allow us to achieve success, in one way or another. The second part will be devoted to the story of Kireeti Kompella's relatively fresh draft [Multi-path Label Switched Paths Signaled Using RSVP-TE], and a description of how to use its Juniper implementation to solve some problems.
The task of efficient utilization of communication channels in the RSVP-TE network has much in common with the task of packing things in bags, suitcases or containers before release. Everyone who did this will say that things of approximately equal size fit much easier and more evenly. It’s good if the size of things is noticeably smaller than the size of the container, but when suddenly there is a need to fit a voluminous object into one of the bags already ready for departure, re-sorting is inevitable. In the RSVP-TE world, this is called a bin-packing problem. To understand what I'm talking about, look at Figure 1, the green and blue lines are the LSP1 set along the ACDE and LSP2 path along the BCE path at times T = 1 and T = 2, respectively. If at time T = 3 the LSP2 band would need to be expanded to a value of 8, the capacity of the CE channel would not allow this. In the world of things and suitcases, we would spend a little time re-sorting things to solve this problem. RSVP-TE allows, with certain reservations, to do the same, for it came up with setup and hold LSP priorities, a potentially wider LSP can be assigned a high priority so that narrow LSPs move, however this approach works just until the same priorities come up for the LSP and then everything repeats.
This happens for two reasons:

Returning to the problem of luggage, we could try to make out the suddenly discovered thing to such an extent that all its parts evenly fill the free space of several luggage. A similar idea was proposed by Kireeti Kompella for optimal utilization of communication channels in the RSVP-TE environment. Instead of signaling one thick path, the router, taking into account the current topology and channel utilization, cheats and signals several less stringent paths, they are called sub-LSPs in the draft. Figure 2 shows how this might look like with respect to the expansion of the LSP2 bandwidth to a value of 8, the router runs a pair of sub-LSPs with lanes of 4 and spreads the traffic along two possible paths.
So, in the draft, a new MLSP concept or container appears; this concept defines a configuration object and controls the set of sub-LSPs. In other words, the TE properties and requirements fixed in the container generate some set of physical LSPs satisfying
constraints and network capabilities. The exact algorithm for calculating the number of sub-LSPs and the bandwidth of the reserved sub-LSP is not described, this is all given to the free implementation of vendors, there are only two caveats to this effect:
The sub-LSPs belonging to a particular MLSP instance are signaled in such a way that transit routers can determine this membership, for this the Path message assumes the use of an ASSOCIATION RSVP with a unique value for each MLSP. Interestingly, before version 4 of the draft, it was supposed to use the Sender Template fields as an identifier. Identification of the sup-LSP membership is useful in that it allows a fairly simple tag saving mechanism, the downstream router does not need to reserve a unique label for each sub-LSP, it is enough to determine which MLSP belongs to the sub-LSP being installed and return the common label to the upstream router.
Depending on the capabilities of the switching chip of the transit router, the draft describes two options for organizing traffic at the data plane level. The first option, called Equi-bandwidth LSP, is to evenly distribute traffic flows across all sub-LSPs on each transit router. The behavior of traffic flows fully complies with per-hop ECMP balancing with the ability to use everything and not just IGP Best. The second possibility implies a weight distribution of traffic flows over the sub-LSP in accordance with the reserved band. It also stipulates the possibility of alternative (at the discretion of the vendor) options for organizing the data-plane.
This data-plane organization has an interesting property — in some topologies, fast convergence in case of accidents is a self-evident consequence even without using mechanisms like MPLS TE Protection, so if the BC channel in Figure 3 fails, router B does not install any repair paths , is able to restore traffic by itself by simply removing one next-hop from the table before the crash information is available to Router A.
Further analysis of the draft pick risks turning into a retelling, so let's move on to examples of use. At the moment, I know only one option, which with certain reservations can be called at least the ideological realization of the draft. The main complaint is that the label saving and sub-LSP identification mechanisms have not yet been implemented, however, a convenient tool for solving some TE problems has turned out. By the way, Juniper Container LSP is fully compatible with classic implementations of RSVP-TE from other manufacturers; this, in my opinion, is a serious plus of this form of implementation.
Attractive is the ability to use Full Mesh Container LSP between PE routers in combination with P devices without serious label stack hashing capabilities. Instead of balancing traffic on each transit router, the Container LSP uses a flexible sub-LSP calculation and signaling mechanism. The algorithm is able to autonomously adjust the number of sub-LSPs, their paths and the occupied bands to the capabilities and topology of the network. The configuration parameters of a container, or a sub-LSP set, their properties and limitations are transferred to the algorithm's input:
The aggregated band is periodically updated based on the band statistics of each sub-LSP and is the sum of these values. The remaining parameters of the container are set manually in accordance with the desired values. Autonomous operation is supported by a periodically repeating normalization event, at which time the algorithm makes one of the following decisions:
The current version of the normalization algorithm performs the calculation, which results in a set of sub-LSPs with equal bandwidth. For example, if the aggregated band is 10, as a result of the calculation, a sub-LSP may appear with the following parameters: 2 through 5, 5 through 2, or 3 through 3.3, if there are several options, the algorithm chooses the one that requires a smaller number of sub-LSPs. Between normalization events, the bandwidth of each sub-LSP can be changed individually using the auto-bandwidth mechanism. At the next iteration of the normalization, the algorithm will collect the current band readings and perform one of its possible actions, the actions of deleting or adding a sub-LSP are performed if the current band of any sub-LSP goes beyond the splitting / merging range. Adding or deleting a sub-LSP is accompanied by band recalculation with the following limitations:
The smallest N value satisfying these inequalities is used to calculate the new sub-LSP band by a simple formula
If the CSPF algorithm fails to find paths with the desired free band, for example due to fragmentation of the free band, N is increased by one, which reduces the individual sub-LSPs band, and the process of finding paths is repeated.
To demonstrate the behavior of the Container LSP, I put together a scheme like this. The bandwidth of each interface is reduced to 10Mbit / s.
We start with the configuration on router A, we need to explicitly enable the collection of LSP statistics (lines 1-3), specify the template from which the sub-LSPs will be created (lines 4-11) and write the properties of the LSP container towards router B (lines 12-22 )
After activation of the code, the container is initialized, and, since. Traffic statistics are not yet established. The minimum number of sub-LSPs with a band equal to the split band. After some time, the auto-bandwidth mechanism accumulated statistics (zero in this case) and adjusted the band.
In a live network, it is better to estimate the traffic order in advance, and prepare the necessary number of sub-LSPs with an approximate band. This can be done using the minimum-member-lsps and merging-bandwidth parameters (lines 15 and 17).
Now we will generate something about 7Mbps of traffic, and analyze what we got. I waited a while to parse the chronology after the normalization event.
Before the occurrence of the auto-bandwidth update and normalization events, only the statistics change. Note the Max AvgBW util and Sampled Aggregate bandwidth values, the first is the current sub-LSP band, the second is the actual container band.
After some time, the auto-bandwidth mechanism corrected the band of a single sub-LSP;
After some time, the moment of normalization arrived, and since the band actually occupied by the LSP is outside the merge / splitting range, the algorithm decided to add another sub-LSP.
Now let's add about 2Mbps of traffic, judging by the testimony of the Sampled Aggregate bandwidth and
Max AvgBW util statistics crawled up.
After some time, auto-bandwidth adjusted the bandwidth of both sub-LSBs.
And the normalization algorithm added another sub-LSP.
In the case when the entropy of packets transmitted in the LSP is high, you can activate the passive auto-bandwidth mode, in this case the band will be updated only during the normalization process, thereby saving some CPU time.

This happens for two reasons:

- local, non-deterministic calculation and optimization of paths on each router;
- lack of mechanisms to coordinate the calculation of paths between routers.

- the amount of the reserved sub-LSPs band must not be less than the container requirements.
The sub-LSPs belonging to a particular MLSP instance are signaled in such a way that transit routers can determine this membership, for this the Path message assumes the use of an ASSOCIATION RSVP with a unique value for each MLSP.

N - sub-LSP, X - , minimum-member-lsps - sub-LSP, maximum-member-lsps - sub-LSP, splitting-bandwidth - , merging-bandwidth -
[X/splitting-bandwidth] ≤ N ≤ [X/merging-bandwidth]
minimum-member-lsps ≤ N ≤ maximum-member-lspsThe smallest N value satisfying these inequalities is used to calculate the new sub-LSP band by a simple formula
B = X / NIf the CSPF algorithm fails to find paths with the desired free band, for example due to fragmentation of the free band, N is increased by one, which reduces the individual sub-LSPs band, and the process of finding paths is repeated.
