Abstract: An example method for distributed service chaining is provided and includes receiving a packet belonging to a service chain in a distributed virtual switch (DVS) network environment, the packet includes a network service header (NSH) indicating a service path identifier identifying the service chain. The packet is provided to a virtual Ethernet module (VEM) connected to an agentless service node (SN) providing an edge service such as a server load balancer (SLB). The VEM associates a service path identifier corresponding to the service chain with a local identifier such as a virtual local area network (VLAN). The agentless SN returns the packet to the VEM for forwarding on the VLAN. Because the VLAN corresponds exactly to the service path and service chain, the packet is forwarded directly to the next node in the service chain. This can enable agentless SNs to efficiently provide a service chain for network traffic.

Abstract: In order to facilitate efficient and scalable lookup of current hop limits of transmitted packets, a communications device embeds hop limit values along with other connection parameters in a connection data structure. To transmit a packet for a particular connection, the communications device retrieves the data structure for the particular connection and applies the hop limit value embedded in the data structure to the packet for transmission. To keep track of the hop limits being embedded in different data structures of different connections, the communications device use a binary search in which each node of the search tree correspond to a different connection. The communications device maintains one such search tree per communications interface.
