Struct AdmissionParameters 

pub struct AdmissionParameters {
    pub max_subscriptions_per_peer: u32,
    pub max_header_fetches_per_peer: u32,
    pub max_transaction_fetches_per_peer: u32,
    pub max_commit_fetches_per_peer: u32,
    pub max_commit_fetches_total: u32,
}

Per-peer, per-RPC concurrency caps for the inbound consensus gRPC server.

Each cap bounds how many concurrent requests of one RPC group a single committee peer (keyed on its authenticated authority index) may have in flight; a peer cannot consume another peer’s budget. These are local, non-protocol parameters — heterogeneous values across authorities are safe, so they can be rolled out and tuned per node.

The defaults are sized for ~100-validator committees and the local synchronizer fan-out toward one server. 0 turns a cap off; each cap is checked on its own.

Fields

max_subscriptions_per_peer: u32

Max concurrent block-subscription streams per peer.

If unspecified, this will default to 2.

max_header_fetches_per_peer: u32

Max concurrent header fetches per peer (fetch_block_headers + fetch_latest_block_headers).

If unspecified, this will default to 32.

max_transaction_fetches_per_peer: u32

Max concurrent transaction fetches per peer (fetch_transactions).

If unspecified, this will default to 16.

max_commit_fetches_per_peer: u32

Max concurrent commit fetches per peer (fetch_commits + fetch_commits_and_transactions).

If unspecified, this will default to 8.

max_commit_fetches_total: u32

Max concurrent commit fetches across all peers, beyond which a peer is still granted its first. A fast commit-sync response holds its commits and certifier headers until it has been sent, and reads its transactions from the store while it is being sent, so this caps what serving them can cost the node at once, short of one response per peer.

If unspecified, this will default to 16.
